1/31/09: Saturday’s Weather Report

Issued at 4:30 PM CST, Saturday, January 31st, 2009

Surface Analysis at 22z:

Low pressure averaging 982 mb was moving into the Southwest half of Ontario. A warm front attached to this low had lifted into far Northeast Minnesota with a cold front attached to this low just entering far Northwest Minnesota. A prefrontal trough or wind shift line was noted over Central Minnesota. Strong pressure rises of 2-3 mb per 2 hours were occurring This Afternoon behind the trough and cold front and on the southwest side of the deep low off to our north.

The January thaw came in with a vengenance around Minnesota Today as high temperatures soared through the 30s and 40s with even a few locations out West inching close to the 50 degree mark! The 60 and 70 degree temperature contours came as far north as far Southern Nebraska and far Southern Iowa Today. Strong warm advection partially responsible in causing these very warm temps around Minnesota Today was shifting east of the state as of late Today with strong cold advection (aloft) crashing southeast through the state.

Upper Air Analysis at 22z:

Strong shortwave was tracking into Western-Southern Ontario with the flow aloft generally from the west around Minnesota Today. This storm is causing quite a bit of snow Today to the north of the surface low with many locations in Western and Central Ontario back into Manitoba seeing their visibilities drop to fractions of a mile Today in moderate to heavy snow. Very impressive 12 hour H5 height falls of 150-270 meters were spreading east out of the Dakotas and Southern Canada Today in assocation with this powerful storm system. H85 temperatures at 22z ranged from +2 to +6 degrees C across Central, Eastern, and Southern Minnesota to zero to -6 degrees C in Northern and Western Minnesota. Even colder air with H85 temps of -20 degrees C were found over Central Manitoba. Another aspect of this big storm has been the howling winds that have affected Western Minnesota Today. 500 mb winds were up to 90 knots This Afternoon from North Dakota and Northern South Dakota through Western and Central Minnesota with 40-60 knot 850 mb winds across the Northern Plains and Upper Midwest. These very high winds aloft were able to mix down to the surface Today with 30 to 55 mph winds occurring across much of Northwest and Western Minnesota.

Today’s Weather:

Cloudy skies with areas of fog, flurries, and a bit of light freezing drizzle did occur over portions of Minnesota late last night through This Morning as a warm front pushed east-northeast across the state. As of late Today, only far Northeast Minnesota was still seeing areas of fog and low clouds while mostly cloudy skies associated with the cold advection part of this storm were found across Northern and Northwest Minnesota, the rest of the state was still seeing clear to mostly clear skies.

Temperatures around Minnesota at 4 PM ranged from 46 degrees at St. Paul to 36 degrees at Bemidji to 32 degrees at Detroit Lakes to 43 degrees at Grand Rapids to 46 degrees at Hibbing to 39 degrees at Ortonville to 46 degrees at Aitkin to 45 degrees at Moose Lake to 46 degrees at Granite Falls to 47 degrees at Glencoe to 43 degrees at Winona.

Here are some wind speeds around Minnesota at 4 PM with the wind gusts in parenthesis.

Hallock: W at 33 mph (45 mph)

Thief River Falls: W at 32 mph (44 mph)

Flag Island: W at 43 mph (49 mph)

Alexandria: NW at 31 mph (41 mph)

Aitkin: (39 mph)

Brainerd: (35 mph)

Grand Rapids: (35 mph)

International Falls: (36 mph)

Tonight through Sunday Night:

*High Wind Warning* continues until 6 PM CST Tonight for extreme Western Minnesota.

*Wind Advisory* continues until Midnight CST Tonight for Northwest and Western Minnesota.

Strong low pressure will continue on it’s eastward track, passing north-northeast of Minnesota during this forecast period. A cold front will push rapidly to the southeast and through all of Minnesota by late This Evening which will then be followed by a secondary cold front which will drop south into Northern Minnesota by Sunday Night. Look for partly to mostly cloudy skies across Minnesota during this period with flurries or a few snow showers possible Tonight, mainly across Northern Minnesota…Then a few snow showers or flurries could occur over all but Western and Southern areas of the state Sunday and Sunday Night. Low temperatures Tonight will be in the teens and 20s with some single digits possible Northwest, but with winds staying up the whole night and the real strong push of cold air remaining aloft, it’ll be pretty difficult for readings to fall into the single digits Tonight. Highs on Sunday will be in the teens and 20s with 30s possible Southeast. Lows Sunday Night will be in the single digits and teens with subzero readings possible Northwest. Winds Tonight through Sunday Night will be out of the west, northwest, or southwest. Wind speeds will average 15 to 25 mph, but wind gusts of 25 to 50 mph will continue around the state, especially Tonight.

Extended Forecast:

Colder air will move into Minnesota early next week as the flow aloft once again becomes north to northwest, it doesn’t appear that this cold blast will be too significant though, but with H85 temps falling to -18 to -24 degrees C…This could still support nighttime lows into the double digits below zero early next week for parts of Minnesota. A vigorous upper trough will be sliding south and east across Minnesota on Monday…This system could bring some snow showers or flurries to parts of the state at that time, in addition, winds aloft look to veer to the NE for a time late Monday Afternoon or Evening which could lead to a brief period of lake effect snow near Lake Superior in Northeast Minnesota. By Mid-week, temperatures should be moderating a bit as the early week cold blast shifts east of Minnesota thanks to an area of low pressure which will approach the state from the northwest, precipitation looks minimal with this system though. By later next week or next weekend we could see a low pressure system lift out of the Plains while another low moves in from the west-northwest. Right now this system looks pretty moisture starved, but it may be able to tap into a little bit of gulf moisture and cause areas of snow, rain, or freezing rain over parts of Minnesota late next week or next weekend.

High temperatures Monday and Tuesday will be in the single digits and teens with some spots up North possibly staying below zero. Lows Monday Night and Tuesday Night will be in the single digits, teens, and 20s below zero.

Forecast for Duluth/Superior:

.Tonight… Windy. Partly to mostly cloudy. Low 20 to 25. Wind west at 15 to 25 mph with gusts of 25 to 40 mph possible.

.Sunday… Breezy. Considerable cloudiness with flurries possible. High 28 to 34 with temperatures falling through the 20s. Wind west at 15 to 25 mph.

.Sunday Night… A few flurries or snow showers possible. Mostly cloudy. Low 10 to 15. Wind west to northwest at 10 to 20 mph. Chance of snow 20%.

.Monday… A few flurries or snow showers possible. Mostly cloudy. High 15 to 20. Chance of snow 30%.

.Monday Night… A few flurries possible. Low 2 below to 7 below.

.Tuesday… Partly cloudy. High 8 to 13.

.Tuesday Night… Partly cloudy. Low 4 below to 3 above.

1/31/09: Incredible warmth/powerful storm

Issued at 12:50 PM CST, Saturday, January 31st, 2009

At 1830z a deep area of low pressure averaging 984 mb was centered over Eastern Manitoba with strong darkening noted on water vapor satellite imagery surging southeast across the Northeast half of North Dakota into Northwest Minnesota. This powerful low is causing temperatures to sky rocket over all but Northern and Northeast Minnesota early This Afternoon in addition to this, high winds were spreading through North Dakota and will soon move into Western Minnesota. *Note: 51 mph wind gust recently at Crookston Minnesota per 1 PM observation.

*High Wind Warning* is in effect through 6 PM CST Today for far Western Minnesota with a *Wind Advisory* in effect from 6 PM This Evening until Midnight CST Tonight for this same area. Some cities included in these headlines are… Crookston… Moorhead… Hallock… Warren… And Breckenridge.

*Wind Advisory* is in effect from 3 PM CST Today to Midnight CST Tonight for parts of Western Minnesota. This advisory includes the following cities… Baudette… Red Lake… Bagley… Bemidji… Park Rapids… And Wadena…

Wind speeds in the advisory area will be in the 20 to 40 mph range This Afternoon and Tonight with wind gusts of 40 to around 60 mph possible for several hours in the high wind warning area. Winds this strong could knock down trees and power lines. These strong winds will also cause areas of blowing snow to develop which will limit visibilities to under a mile at times.

Additional wind headlines may be needed for other parts of Minnesota later Today or Tonight as 850 mb winds increase to 40-60 knots as deep low pressure passes north of Minnesota and causes strong winds to occur west and south of the area of low pressure.

At Noon Today, surface temps had risen into the 30s and 40s across all but Northern and Northeast Minnesota where readings were still holding in the 20s thanks to low clouds and areas of fog which was dense in some locations. Some locales out in Westcentral Minnesota were even close to 50 degrees at Noon Today.

850 mb temperatures at 12 PM CST ranged from +2 to +10 degrees across all but Northeast and far Northern Minnesota.

3 hour temperature rises per RUC model have been in the 12 to 16 degree range across much of Minnesota early This Afternoon…Pretty incredible!

Here are some of the lower pressure readings as of late This Morning and early This Afternoon in response to this strong area of low pressure.

Hallock MN: 29.16″

Roseau MN: 29.08″

Warroad MN: 29.09″

Baudette MN: 29.11″

Flag Island MN: 29.06″

Winnipeg Manitoba: 29.06″

The temperature inversion which developed in Duluth This Morning has broken as of Noon Today. Fog and low clouds have burned off, giving way to sunshine as of early Afternoon. Some examples of the inversion…At 9 AM Today, the 925 mb temperature at Duluth was -5 degrees C…850 mb temperature was around zero to +2 degrees C…Surface temperature was -8 degrees C… At 12 PM CST Today, the 925 mb temperature at Duluth was around -4 degrees C…850 mb temperature was +2 degrees C and the surface temperature was -2 degrees C. This wasn’t a very strong inversion, so all we needed to do was break the sun out and cause some of the gusty winds aloft to mix down to the surface which we’ve done.

High temperatures for the rest of Today could really take off in the city as readings to our west and northwest were in the upper 30s to low and mid 40s as of 1 PM Today. 40s were as far east as Grand Rapids, Aitkin, and Brainerd.

High temperature forecast of 25 to 30 degrees for Duluth Today will have to be raised to 35 to 40 degrees, I do believe will top the freezing mark for the first time this month.

1/30/09: Friday’s Weather Report

Issued at 3:12 PM CST, Friday, January 30th, 2009

If the high temperature fails to reach 32 degrees at Duluth on Saturday, then this will go down as just the 15th time since 1874 that a January has failed to produce a temperature of 32 degrees. It’s a tricky forecast for the city on Saturday, we have pros and cons at the present time. One thing favorable for temps reaching or even exceeding 32 degrees is that will have a southwest to west surface wind, plus a deep surface low will be passing by to our north putting us in the warm sector for a time. Negatives would include the deep snow cover and the fact that we may be dealing with a temperature inversion with warm air aloft and cooler air trapped at the surface, but if the strong winds aloft can mix down to the surface, then this inversion will break up enough allowing for sunshine to develop which would aid in warming things up and causing the mercury to possibly reach the freezing mark for the first time this month. The last time the high temperature failed to reach 32 degrees in January at Duluth was back in 2004, prior to this was 1994.

Surface Analysis at 20z:

Active storm track across Canada with three lows up in that area Today. One low averaging 1004 mb was centered over the Western half of Quebec Province. A second low averaging 1008 mb was centered over the Northwest half of Ontario Province. A third low averaging 977 mb was moving toward Northern British Columbia. A warm front was attached to the Ontario low with this boundary extending from Eastern Manitoba down through the Eastern Dakotas. A cold front extended from Central Manitoba to Central Saskatchewan. High pressure averaging 1020 mb was centered over the Southern half of Missouri.

Upper Air Analysis at 20z:

Northwest flow aloft was in place over the Upper Midwest Today with a strong upper trough associated with last night’s arctic blast around Minnesota moving through the Eastern Great Lakes toward Eastern Canada. An upper trough was moving into Northwest Canada with 12 hour H5 height falls of 90-120 meters This Afternoon…This system was moving toward the east-southeast. Strong warm advection was taking place across the Upper Midwest This Afternoon with 3 hour surface temperatures rising 8-12 degrees around Minnesota, moisture was also increasing as evident by surface dewpoints which have gone up 6 to 12 degrees over the last 3 hours. H85 temperatures at 3 PM ranged from -12 to -16 degrees C from Northern to Eastern Minnesota to -8 degrees C in Southwest and far Western Minnesota. The zero degree C 850 mb contour was still over the Central Dakotas as of Mid-Afternoon, while the real warm air with +4 to +12 degree C 850 mb temps centered over the Western Dakotas through the Northern Rockies. Strong warm advection will persist around Minnesota into early Saturday Afternoon with the zero degree C 850 mb temperature line reaching Northern and Northeast Minnesota, while Western and Southern areas of the state see their temperatures aloft warm to +4 to +6 degrees C on Saturday.

Surface temperatures were in the mid 30s and 40s This Afternoon over the Central and Western Dakotas with 50s around the Rapid City area, the above freezing temperatures extend up into Saskatchewan and parts of Manitoba Today, so this area of warm air, albeit cooler than what is occurring Today will be moving over Minnesota on Saturday since the flow aloft is from the northwest, and soon to be more from the west.

Today’s Weather:

Saw partly to mostly cloudy skies around Minnesota Today with the most cloudiness out in Western Minnesota and the most sunshine farther East, this is changing though late Today as clouds are overspreading Northern and Eastern areas of the state. There’s been some flurries and light snow at times Today outside of Eastern Minnesota, but none of this has been very significant. High temperatures around Minnesota were in the teens and 20s Today with some 30s showing up in Southwest Minnesota. Winds across the state were out of the south or west Today around 10 to 20 mph.

Temperatures around Minnesota at 3 PM ranged from 10 degrees at Lake Elmo to 14 degrees at Thief River Falls to 14 degrees at Grand Rapids to 16 degrees at Moorhead to 9 degrees at Ely to 28 degrees at Wheaton to 14 degrees at Brainerd to 10 degrees at Mora to 31 degrees at Canby to 27 degrees at Pipestone to 14 degrees at Mankato to 12 degrees at Red Wing.

Tonight:

A warm front will inch east through Western toward Central Minnesota during the night. Look for partly to mostly cloudy skies around Minnesota with the potential for some light snow and flurries over Northern, Central, Southern, and Eastern Minnesota. A bit of light freezing drizzle may also develop Overnight across Northcentral into Eastcentral Minnesota. Little if any accumulation of snow is expected Tonight with any ice accumulations remaining under 0.01″, but it may be enough to cause some slick spots early Tomorrow Morning. Temperatures Tonight will remain steady or slowly rise through the night with readings generally in the single digits, teens, and 20s with some areas in Southwest and Western Minnesota possibly staying around 30 degrees. Winds will be out of the south or west around 10 to 20 mph.

Saturday and Saturday Night:

*Blizzard Watch* is in effect from 12 PM til 6 PM CST for far Northwest and far Western Minnesota. Some cities included in the watch are: Crookston… Moorhead… Hallock… And Warren…

A strong area of low pressure between 984-989 mb will track into Southern Ontario Province, passing near the Lake Nipigon area during this forecast period. A warm front and cold front attached to this low will be advancing east-southeast through the state into Saturday Evening. Warmer air will be over the state on Saturday which will then be replaced by a new surge of cold advection which will move in Saturday Night behind the low and cold front. Partly to mostly cloudy skies will cover the state Saturday and Saturday Night with some flurries possible at times in Northern Minnesota. Patchy light freezing drizzle may also occur Saturday Morning from Northcentral through Eastcentral Minnesota. High temperatures on Saturday will rise into the 20s and 30s with 40s possible in Southwest Minnesota. Lows Saturday Night will be in the single digits, teens, and 20s. Winds will shift from the south and west to the north and west during this forecast period. 850 mb winds are forecast to increase to 35 to 55 knots across much of Minnesota on the west and south sides of the deep low off to our north, some of these higher wind speeds should make it down to the surface with 15 to 35 mph winds expected over most of Minnesota, wind gusts could reach 35 to 50 mph though over Western areas of the state. If the winds increase this much, then ground blizzard conditions could develop for a time Saturday over far Western Minnesota. The current snow pack is pretty crusty though, so it will take some strong winds to loosen up the top layer of snow cover.

Extended Forecast:

Low pressure will be passing off to the northeast of Minnesota to close out the weekend while a 500 mb trough swoops east-southeast into the Upper Midwest Sunday and Monday, this trough will deepen as it passes through our area. This upper trough combined with a potential storm along the East Coast early next week will help to pull another batch of arctic air currently seen over Northern and Eastern Alaska through the Yukon and Northwest Territories in Canada down into Minnesota from Monday through early Wednesday the way it looks now. Temperatures in the areas where the arctic air has been building the last few days have been down into the 30s, 40s, and even 50s below zero during the night and Morning hours, but as this arctic surge drops southeast it should modify somewhat, but it still looks plenty cold around Minnesota early next week. The Sunday through Tuesday period looks pretty dry around Minnesota, but there could be some flurries or snow showers passing through from time to time. High temperatures on Sunday will be in the single digits, teens, and 20s with lows Sunday Night in the single digits and teens below to above zero. Highs Monday will be in the single digits and teens with some spots in the North possibly staying below zero. Lows Monday Night will fall into the single digits, teens, and 20s below with some 30s below possible over parts of the North. Again this next cold surge should linger into Wednesday Morning, then temperatures should start to moderate the remainder of next week possibly into next weekend. GFS model continues to show a potential weather system possibly affecting Minnesota’s weather later next week or next weekend with another system possible early the following week. Both systems could bring some snow, ice, or even some rain to parts of the state, but again it’s way too early to nail down the exact timing, strength, and tracks of these lows.

Forecast for Duluth/Superior:

.Tonight… Becoming mostly cloudy. Snow flurries or patchy light freezing drizzle possible late. Low 5 to 10 with temperatures steady or slowly rising Overnight. Wind southwest at 5 to 15 mph.

.Saturday… Breezy. Patchy light freezing drizzle possible early. Mostly cloudy during the Morning, then becoming partly sunny. High 25 to 30. Wind southwest at 15 to 25 mph, becoming west.

1/29/09: Thursday’s Weather Report

Issued at 4:24 PM CST, Thursday, January 29th, 2009

Weather History:

On this date in 2008, the high temperature reached 35 degrees at Duluth Minnesota, but a new blast of arctic air sent the low temperature plummeting to 19 degrees below zero on the same day. That’s a difference of 54 degrees in 24 hours!

Surface Analysis at 22z:

Low pressure averaging 1004 mb was centered over Eastern Ontario with high pressure averaging 1018 mb centered over Southern Manitoba.

Upper Air Analysis at 22z:

Northwest flow aloft has amplified a bit Today around the Upper Midwest as a new surge of arctic air spreads south into Minnesota behind the weak system that moved through last night. An upper level trough was seen on water vapor satellite imagery progressing east across the Upper Midwest and Upper Great Lakes Today with a few disturbances rotating south-southeast along and behind this upper trough. A 120-140 knot jet max was found from Central Saskatchewan Province through Eastern Montana and the Western Dakotas Today on the backside of this upper trough. 850 mb temperatures around Minnesota at 4 PM Today ranged from -18 degrees C across Northern Minnesota to -12 to -14 degrees C in Southern Minnesota. The coldest air with this latest arctic blast was found north-northeast of Minnesota Today where the lowest 500 mb heights were found and the coldest 850 mb temps of -20 to -22 degrees C were located.

Today’s Weather:

Partly to mostly cloudy skies covered Minnesota Today with a few light snow showers and flurries falling at times over parts of the state. Snow accumulations from Wednesday Afternoon through This Morning were generally an inch or less, but the Arrowhead of Minnesota picked up around two inches of snow thanks to some lake effect which occurred for a time on Wednesday. High temperatures around Minnesota were in the single digits below to above zero with teens and 20s farther South. Winds across the state were out of the north or west Today at 10 to 20 mph with some higher gusts over Western and Southern Minnesota. Afternoon wind chills were mostly in the single digits below to above zero with teens and even some 20s below farther North.

Temperatures at 4 PM around Minnesota ranged from 14 degrees at South St. Paul to -2 degrees at Hallock to -2 degrees at Detroit Lakes to 1 degree at International Falls to 7 degrees at Hibbing to 1 degree at Wadena to 10 degrees at Aitkin to 11 degrees at Rush City to 19 degrees at Pipestone to 18 degrees at St. James to 14 degrees at Dodge Center.

Tonight:

High pressure will be in control of Minnesota’s weather. Look for partly to mostly cloudy skies with any flurries ending during the Evening. Lows will be on the cold side with readings in the single digits, teens, and 20s below zero with some locations staying on the positive side of zero in Southwest Minnesota. Winds will be out of the west or northwest around 15 mph.

Friday and Friday Night:

Low pressure will tracking to the north-northeast of Minnesota during this period while a warm front moves into Minnesota from the west by Friday Night. Could see some flurries or some patchy light freezing drizzle develop over parts of Minnesota during this period as strong warm advection pattern develops. Look for partly to mostly cloudy skies Friday and Friday Night with highs in the single digits, teens, and 20s with nearly steady or slowly rising temperatures Friday Night. Winds during this period will shift to the south and southwest around 10 to 25 mph.

Extended Forecast:

Strong area of low pressure around 988 mb will be tracking into Central Canada this weekend. A push of warmer air will occur south of this low and ahead of a cold front on Saturday with 850 mb temps climbing to between +2 and +6 degrees C with the warmest air the farther South you go. Problem with getting this warm air above us to mix down to the surface will be the possibility for cloud-cover which could cause an inversion to develop allowing the warmest air to stay aloft, the best potential to see temperatures rise above 32 degrees on Saturday seems to be over Southwest and possibly Westcentral Minnesota, the rest of Minnesota should see highs mainly in the 20s to near 30 degrees. The period from Saturday Night through Monday will see an upper level trough move in from the west-northwest, this upper trough will deepen and cause a more amplified upper air pattern to develop as we head into the early to possibly mid part of next week. What will also help to amplify the pattern will be a potential bomb of a storm that could take shape and ride northeast along the Appalachins or slightly farther east from there from Monday through Wednesday of next week, this storm has the possibility of being a major system with a severe winter storm and possible blizzard to the west and northwest of the low track with flooding rains along and ahead of the track. This storm will stay well to the east of Minnesota, but it will still have some influence on our local weather since it will help to bring down another shot of arctic air early next week.

Low temperatures around Minnesota will be in the single digits, teens, and 20s Saturday Night with high temps on Sunday holding pretty steady from Saturday’s low temperatures. Lows Sunday Night will be in the single digits below to above zero with some teens farther South.

Low temperatures Monday Night and Tuesday Night of next week could drop back into the teens, 20s, and possibly even some 30s below zero over portions of Minnesota based off the latest GFS model run This Afternoon…The Euro model is slightly warmer, but still supports another cold push early next week.

Now, as I stated yesterday the weather pattern may change after the middle of next week once that monster storm along the East Coast moves out, this new pattern may lead to more active weather around the Upper Midwest for early and mid February, but this Winter has seen a very reluctant N/NW upper level flow pattern that just doesn’t wanna leave for long periods of time, this is reflected by the 18z GFS model run Today which shows a powerful 1064 mb arctic high building south out of the Yukon region and giving Minnesota another dose of arctic air toward the second week of February.

Forecast for Duluth/Superior:

.Tonight… Clear to partly cloudy. Low 4 below to 11 below. Wind northwest around 15 mph.

.Friday… Partly sunny. High 10 to 15. Wind becoming southwest at 10 to 15 mph.

.Friday Night… A few flurries possible. Mostly cloudy. Low 5 to 10 with slowly rising temperatures. Wind south to southwest at 10 to 15 mph.
