Forecast Discussion for Northeast Minnesota and Northwest Wisconsin

(Today’s Weather)

A strong area of low pressure averaging 996 mb was centered over the Southwest portion of Ontario Province as of 2 PM with a strong cold front extending from Northeast Minnesota through Western Wisconsin. Airmass along and ahead of this front was characterized by widespread low cloudiness Today with dewpoints generally in the 60s with 850 mb td’s of +12 to +16 degrees C with PWS of 1.50″-1.70″. The clouds have kept temperatures generally in the 60s and 70s This Afternoon which has kept CAPES generally under 500 j/kg. Result from all this has been for a broken line of showers with some heavy downpours and perhaps an isolated thunderstorm or two along the cold front across Northwest Wisconsin and far Eastern Minnesota This Afternoon. As the cold front passes by…skies become partly-mostly sunny with gusty west winds at 15-30 mph with somewhat drier air advecting in behind the cold frontal boundary.

(Today’s Upper Level Analysis)

A strong upper level trough with 60 meter 12 hour H5 height falls continued to spread through the Northern Plains into the Upper Midwest This Afternoon with the dry slot associated with this wound up storm system progressing quite rapidly toward the east-northeast from Westcentral Minnesota.

(Tonight)

Low pressure will deepen to around 991 mb during the night as it remains over Southern Ontario Province. The potent upper level trough over the Dakotas This Afternoon will continue to push south-east into our area Tonight. Scattered showers and isolated thunderstorms will continue in far Northeast Minnesota and Northwest Wisconsin before 7 PM Tonight as the cold front attached to this low continues to push north-east through those areas. Meanwhile scattered strong to severe thunderstorms developing over the Dakotas This Afternoon under the cold H5 trough could make a move toward the western-southern parts of our area before Midnight with a threat for a few showers or thunderstorms generally over Cass and Crow Wing counties in Minnesota before this activity dissipates toward the late Evening hours. Otherwise expect partly-mostly cloudy skies Tonight with lows in the 50s to around 60 degrees. Winds will become southwest or west and will increase to 15-30 mph.

(Sunday and Sunday Night)

Strong low pressure at the surface and aloft will be located to our northeast during this period with gusty west winds at 15-35 mph continuing across our area on the back side of this storm. Look for partly-mostly cloudy skies during this period with shower chances confined to mainly Northern areas of Minnesota both Sunday and Sunday Night… Highs Tomorrow will be in the 60s and 70s with lows Tomorrow Night in the 40s and 50s.

(Extended Forecast)

Looks like our upper level pattern will be going back to a more persistent north or northwest flow aloft across the Upper Midwest through most of next week and possibly beyond this time as upper level ridging heads back into the Western U.S. while to our east we see one if not more cut-off lows take shape over the next week… This type of pattern is generally dry for our area and is not favorable for any sort of severe weather outbreaks with even general thunderstorm activity hard to come by with this type of upper level pattern.

Low pressure will continue to sit and spin over the Great Lakes region through at least Tuesday of next week which will keep our area locked in a cooler northerly flow aloft. The chilliest day appears to be on Monday when high temperatures will only reach the 50s and 60s across Northeast Minnesota and Northwest Wisconsin thanks to extensive cloudiness and H85 temperatures which are forecast to drop to +2 to +6 degrees C across our local area…Pretty unusal to see 850 mb temps that low this time of year. Low temperatures Monday Night will be in the 40s and 50s. Could see some drizzle or areas of showers as well over parts of the area especially on Monday. High temperatures on Tuesday will be in the 60s and low 70s with some 50s possible in far Northeast Minnesota. Lows Tuesday Night will be in the 40s and 50s. Expect partly-mostly cloudy skies for Tuesday and Tuesday Night.

No real big warm ups can be expected across our neck of the woods as long as we see this N-NW H5 flow stay in place… Temperatures for the most part will be at or below normal levels as we move into early July.

6/26/09: Friday’s Weather Report

Issued at 2:39 PM CDT, Friday, June 26th, 2009

Forecast Discussion for Northeast Minnesota and Northwest Wisconsin

(Today’s Weather)

Sunny to mostly sunny skies were found over our area Today with high temperatures in the 70s and 80s with 2 PM 850 mb temperatures of +13 to +18 degrees C. Dewpoints were generally in the 50s This Afternoon with PWS of just 0.60″-0.80″ across our local area. Winds Today were out of the south or east at 10-20 mph which resulted in cooler temperatures with mainly 60s closer to Lake Superior. Weather map at mid-Afternoon features an area of low pressure of 1004 mb over far Western South Dakota with a cold front running from Northwest North Dakota to Northern Wyoming. High pressure of 1014 mb was pulling east away from our area This Afternoon while a warm front was developing from Central South Dakota to Northern Missouri.

(Today’s Upper Level Analysis)

A potent shortwave trough was heading east-southeast through the Pacific Northwest This Afternoon per water vapor satellite imagery with strong jet stream winds of 110 knots noted across Southern Saskatchewan This Afternoon per RUC H3 model analysis. An H5 ridge remained over the Central and Southern Plains Today although it has shrunk a bit in size compared to 24 hours ago as the system to our west starts to deepen and begins to break down this ridge. A W-NW 500 mb flow was in place across the Upper Midwest This Afternoon between the storm to our west and a potent H5 low over Eastern Canada.

(Tonight)

Look for partly to mostly cloudy skies with lows in the 50s and 60s. Winds will be out of the south or east at 10-20 mph. Showers or thunderstorms are expected to develop later Tonight mainly over western and southern parts of our area as the LLJ increases to 30-45 knots Overnight which will help pull deeper moisture currently to our west and southwest northeast into our area during the night. PWS are expected to soar into the 1.00″-1.75″ range by later Tonight over most of our area as low pressure near the Black Hills of South Dakota This Afternoon heads toward the Eastern Dakotas Overnight. Severe weather is not expected Tonight with any thunderstorm that develops due to extremely low amounts of instability…however locally heavy downpours could develop with the increasing amount of moisture in the air.

(Saturday and Saturday Night)

Low pressure will deepen to around 993 mb as it tracks through Western Minnesota Saturday Morning then to Southwestern Ontario Province by Saturday Evening. A cold front attached to this low will surge east and will pass through Northeastern Minnesota between 11 AM-2 PM Saturday and through Northwest Wisconsin between 2 PM-5 PM Saturday.

Showers and a few thunderstorms will likely occur Saturday Morning with some locally heavy downpours possible as a 30-50 knot LLJ continues to pull deeper moisture into our area out ahead of the surface low/cold front.

Some clearing is then expected to take place across Northwest Wisconsin and Eastcentral Minnesota Saturday Afternoon and this could result in CAPES rising toward 1000 j/kg thanks to temperatures which would warm through the 70s to low 80s with dewpoints in the 60s with PWS of 1.00″-1.75″ and H85 td’s of +10 to +14 degrees C.

If we can heat out enough and get enough clearing to develop…then we could see a few thunderstorms re-develop Saturday Afternoon across mainly Northwest Wisconsin and perhaps the far Eastern parts of Minnesota. Should a thunderstorm develop it could become severe Saturday Afternoon with 30-40 knots of 0-6 KM Bulk Shear in place. Damaging winds and large hail would be the main threats if severe weather did develop. Right now the counties of Washburn…Sawyer…Price…Iron…and Ashland seem to be the areas where a low severe weather risk does exist Tomorrow Afternoon.

Another area to watch will be over Cass…and Crow Wing counties in Northcentral Minnesota…These areas will be near the strong upper level trough which will blast south-east out of the Dakotas on Saturday. Some instability and at least weak amounts of moisture will likely remain in place and with some Afternoon heating combined with colder temperatures aloft could cause a few thunderstorms to develop over western parts of the area late Saturday Afternoon-Saturday Evening…Gusty winds and small hail would be the main threats out of those storms if they do develop.

Expect partly-mostly cloudy skies during this period with highs Tomorrow in the 60s and 70s with some 80s in southern parts of our area. Lows Tomorrow Night will be mainly in the 50s. Look for south, west, or east winds to become west or southwest at 10-20 mph during this period with wind gusts nearing 30 mph Saturday Afternoon and Saturday Night.

(Extended Forecast)

Strong low pressure and a very strong upper level trough will set up shop near or over the Great Lakes from late this weekend into perhaps the middle of next week. What this means for our local area will be a northerly upper level flow which will cause temperatures to be much cooler compared to what we have seen as of late. Partly-mostly cloudy skies are forecast on Sunday with showers possible mainly in Northern Minnesota. The threat for showers or some drizzle will then push more to the south and east from Sunday Night into Monday the way it looks now. High temperatures on Sunday will be in the 60s and 70s with lows Sunday Night in the 40s and 50s. High temperatures Monday will only be in the 50s and 60s with lows Monday Night in the 40s and 50s. Winds will also be quite gusty at times on the backside of this strong storm with northwest and north winds of 15-25 mph with gusts around 30 mph expected from Sunday into Monday.

5 Day Forecast for Duluth/Superior

.Tonight… Mostly clear This Evening with skies becoming mostly cloudy Overnight. Showers possible after 2 AM. Low 57 to 62 Inland and 50 to 55 closer to Lake Superior. Wind southeast to east at 10 to 20 mph. Chance of rain 40%.

.Saturday… Showers into early Afternoon. Considerable cloudiness with some clearing possible during the Afternoon. High 70 to 75. Wind southeast at 10 to 15 mph…becoming southwest to west at 15 to 20 mph during the Afternoon. Chance of rain 60%.

6/25/09: Thursday’s Weather Report

Issued at 5:14 PM CDT, Thursday, June 25th, 2009

Forecast Discussion for Northeast Minnesota and Northwest Wisconsin

(Today’s Weather)

A beautiful early Summer day across our area with plenty of Afternoon sunshine, gentle northwest winds, warm temperatures, and tolerable amounts of humidity. High temperatures Today were in the 70s and 80s with 4 PM 850 mb temperatures of +14 to +17 degrees C. Dewpoints were in the 40s and 50s Today with west or northwest winds at 10-20 mph. Today was mainly dry…however a few showers and thunderstorms erupted early This Morning mainly affecting western and southern parts of our area. Surface weather map late This Afternoon features an area of high pressure of 1012 mb over Southeast Manitoba Province with a cold front centered over the Central parts of Manitoba/Ontario Province.

(Today’s Upper Level Analysis)

A large H5 ridge continued to dominate much of the Central and Southern Plains This Afternoon with this ridge extending west through the Central and Southern Rockies. Active spots in terms of scattered strong to severe convection were noted on the northeast side of this ridge across Eastern Canada and the lower Great Lakes and on the northwest side of this ridge across the Northern Rockies This Afternoon. A strong upper level low had moved into Northwest Canada late Today with 60 meter H5 12 hour height falls associated with that feature across Alberta Province per RUC model analysis.

(Tonight)

High pressure will be in control of our weather although we will see that cold front to our north sag a bit to the south during the night. No precipitation is expected with that front since upper level riding will be found over our area Tonight. Lows will be in the 50s and low 60s with west or north winds under 15 mph.

(Friday and Friday Night)

High pressure will head off to our east during this period while a cold front settles into Northcentral Minnesota before stalling out and lifting back north as a warm front by Friday Night. Low pressure will be situated over the Western High Plains during this period with a southerly flow developing across our area out ahead of this low and on the backside of the area of high pressure. Looks like another very nice day on Friday with partly cloudy-mostly sunny skies with high temperatures in the 70s and 80s with a few spots possibly nearing 90 degrees down toward Brainerd. Dewpoints are expected to hold in the 40s and 50s on Friday although muggier air will eventually return to southwest parts of our area by Friday Night. It does look mainly dry across the area during this period…Although showers or thunderstorms should start to affect Western-Southern parts of the area later Friday Night as a 30-40 knot LLJ advects deeper moisture and weak instability into our area. Lows Friday Night will be in the 50s and 60s with partly-mostly cloudy skies. Winds will be out of the south or east during this period at 10-20 mph.

(Extended Forecast)

A fairly strong storm system for early Summer standards will affect our weather this weekend. Strong low pressure is forecast to lift north-east through the Upper Midwest on Saturday with this low then slowing down as it reaches Southern-Central Ontario Province from Saturday Night through late Sunday. A very potent upper level trough will also dig east-southeast into our area this weekend. Looks like we could be setting the stage for a period of windy weather especially from late Saturday into late Sunday as westerly winds increase to 15-30 mph across the area…But with H85 wind speeds of 40-55 knots…The surface winds could end up even stronger than what is expected at this time. Rain chances look greatest on Saturday as the low and it’s warm front/cold front track through the area. Still doesn’t look to promising for much in the way of severe weather around the area…although Northwest Wisconsin and possibly the far Eastern portions of Minnesota could be dealing with an isolated severe weather risk Saturday Afternoon if enough clearing can occur behind Saturday Morning’s glob of rain…although the severe threat will also hinge upon the timing of the cold front which right now appears to be through all of Northeast Minnesota between Noon-2 PM Saturday with the front pushing through Northwest Wisconsin between mid and late Afternoon Saturday. Could see some wrap around showers affect parts of the area later this weekend as the strong upper level trough/surface low move slowly to the east. High temperatures Saturday and Sunday will be in the 60s and 70s with some 80s possible on Saturday in Southern parts of our area. Lows Saturday Night and Sunday Night will be in the 40s and 50s. It should be noted that high temperatures on Sunday may struggle to get out of the 50s in the Arrowhead of Minnesota if clouds and rain are more persistent than what is expected right now.

5 Day Forecast for Duluth/Superior

.Tonight… Clear. Low 56 to 61. Wind west to northwest at 5 to 15 mph.

.Friday… Mostly sunny. High 80 to 85 but turning cooler closer to Lake Superior. Wind variable at 5 to 15 mph.

.Friday Night… Partly to mostly cloudy. Showers or thunderstorms possible Overnight. Low 57 to 62. Chance of rain 20%.

.Saturday… Showers… A thunderstorm also possible. Mostly cloudy. High 67 to 72. Chance of rain 50%.

.Saturday Night… Variable cloudiness. Low 52 to 57.

.Sunday… Variable cloudiness. Showers possible. High 70 to 75. Chance of rain 20%.

.Sunday Night… Partly to mostly cloudy. Low 50 to 55.

Forecast Discussion for Northeast Minnesota and Northwest Wisconsin

(Today’s Weather)

Weak area of high pressure of 1014 mb was building into Northern Minnesota from Eastern North Dakota This Afternoon with a cold front turning stationary across Southern Minnesota. Drier air has been pushing into our local area Today behind this cold front while the real muggy air was confined to Southern Minnesota. Dewpoints across our area were in the 40s, 50s, and low 60s This Afternoon with temperatures in the 70s and 80s along with west, southwest, or north winds around 15 mph or less. 850 mb temperatures as of 2 PM ranged from +15 to +17 degrees C. Partly-mostly sunny skies were found across our area Today with some radar echoes passing through Southern Burnett…Washburn…and Sawyer counties in Northwest Wisconsin Today but there’s been little if any rain reaching the ground.

(Today’s Upper Level Analysis)

Large H5 ridge covered much of the Central and Southern Rockies…Plains…and the Southern parts of the U.S. This Afternoon with the ridge axis extending from Southern California to Central Wyoming to Central Iowa to Southeast Mississippi per RUC model analysis. Fast winds aloft were found north of this ridge from the Pacific Northwest east through the Upper Midwest. Upper level lows were centered just off the Eastern seaboard with a very strong upper level low associated with 150 meter H5 12 hour height falls moving toward Southwestern British Columbia This Afternoon. Of greater concern for our area is the disturbance coming east-southeast out of the Northern Rockies Today although the main impacts out of that feature will likely remain south of our area.

(Tonight)

The aforementioned disturbance moving into the Northern Plains will cause scattered showers and thunderstorms mainly southwest-south of our area Tonight…although some showers may make sneak into the Brainerd/Hinckley/Siren/Hayward/Park Falls area in Minnesota and Wisconsin especially This Evening… Otherwise look for partly-mostly cloudy skies Tonight with lows in the 50s and low 60s but some patchy 40s are possible up North. Winds will be out of the west, north, or southwest around 15 mph or less.

(Thursday and Thursday Night)

High pressure will be in control of our weather although we will see a cold front head south out of Central Canada with this boundary moving into Northern Minnesota later Thursday and Thursday Night. A stray shower or thunderstorm could develop near this boundary in far Northern Minnesota Thursday Afternoon or Thursday Night…otherwise this period looks high and dry across our area with mild temperatures and comfortable humidity levels. Highs Tomorrow will be in the 70s and 80s with lows Tomorrow Night in the 50s and low 60s with some 40s possible once again in Northern Minnesota. Winds will be out of the southwest, west, or north at 10-20 mph.

(Extended Forecast)

High pressure will move off to our east on Friday with a southerly return flow becoming established across the Upper Midwest between the departing high and an area of low pressure which will approach the region from the Northern Rockies/Western High Plains. The cold front which will drop south out of Central Canada is forecast to turn into a warm front across Southern or Central Minnesota on Friday with this boundary lifting north-east Friday Night and Saturday which will then be followed by a fairly potent cold front which should move through our area on Saturday. Showers or thunderstorms are possible as this system moves across the area Friday Night and Saturday. Severe weather chances don’t look very good at this point since it appears that this system will be coming through at an unfavorable time of day to support a bigger severe weather risk for our area…although if it slows down some…then Northwest Wisconsin and Eastcentral Minnesota could be under the gun for some severe weather Saturday Afternoon or Saturday Evening. This system looks fairly dynamic at this point with fairly strong W-SW H5 winds of 35-50 knots and a pretty decent low level jet of 30-45 knots. Shear also looks pretty good at this point as does the moisture return into this system… Will continue to monitor the evolution of this system for any possible changes over the next 24-36 hours. High temperatures on Friday will be in the 70s and 80s with a few spots nearing 90 degrees toward the Brainerd area. It does look like will see an onshore wind kick back up by Friday so it will turn cooler closer to Lake Superior. Lows Friday Night will be in the 50s and 60s. Highs Saturday will be in the 70s and 80s with lows Saturday Night in the 50s to low 60s.

Models diverge greatly from late this weekend into the early part of next week. 12Z GFS from Today has a cut-off low…very chilly temperatures…and off an on rainy spells across our area from Sunday through perhaps the middle of next week as low pressure cuts-off from the main flow of the jet stream allowing it to sit and spin over the Upper Midwest/Upper Great Lakes vicinity from Sunday into the early or mid part of next week. The other long range models aren’t as enthused with the GFS solution Today so perhaps the GFS is up to no good.

Note: The 12z GFS from Today does look pretty extreme late this weekend and early next week considering were almost into early July…But the way this past Spring was I guess anything is possible.

5 Day Forecast for Duluth/Superior

.Tonight… Partly to mostly cloudy. Low 55 to 60. Wind west at 5 to 15 mph.

.Thursday… Mostly sunny. High 80 to 85. Wind west at 10 to 15 mph.

6/23/09: Tuesday’s Weather Report

Issued at 4:08 PM CDT, Tuesday, June 23rd, 2009

Forecast Discussion for Northeast Minnesota and Northwest Wisconsin

(Today’s Weather)

A very warm and humid day across our area with a cold front moving east out of Western Minnesota. Highs were in the 70s and 80s Today with a few locales pushing toward 90 degrees. Dewpoints were generally in the 60s with PWS of 0.80″1.60″…Lowest in the eastern areas with richer moisture to our west and northwest. Winds Today were out of the south or east at 10-20 mph which has caused some cooling closer to Lake Superior. Scattered supercells formed for a time between 1-3 PM This Afternoon in Eastcentral Minnesota…Generally in Crow Wing/Aitkin counties…These storms have for the most part diminished in intensity over the last hour…However additional storms are firing off at times across Crow Wing/Cass counties late Today. Storm motions have been toward the east or east-northeast This Afternoon.

(Today’s Upper Level Analysis)

Hot H5 ridge was baking the Central-Southern Plains This Afternoon while disturbances continue to ride up and around this ridge triggering scattered strong to severe convection across the Northern Plains/Upper Midwest Today. Upper level troughs were in place across the Western U.S. and across the Northeast U.S.

(Tonight)

A cold front will be moving south-east across most of our area during the night. Plenty of instability will be found along and ahead of this boundary Tonight with CAPES of 1000-2500 j/kg during the Evening hours with LI’S of -2 to -8 degrees C. 0-6 KM Bulk Shear and Effective Bulk Shear will range from 30 up to 40 knots with a weak southwesterly LLJ of 20-30 knots and faster H5 winds from the W-SW at 30-45 knots. Scattered showers and thunderstorms will be possible across the area Tonight…although capping issues and a lack of deeper moisture outside of the west-southwest portions of our area could keep the severe threat pretty isolated. If the mid/upper level moisture can increase ahead of the cold front This Evening…then the risk for severe weather could become somewhat more widespread than what were seeing late This Afternoon. Partly to mostly cloudy skies will be found across our area Tonight with lows in the 50s and 60s with south or east winds turning west and northwest around 15 mph. If storms become severe the main threats will continue to be large hail and damaging winds.

(Wednesday and Wednesday Night)

Cold front will settle south out of our area on Wednesday with high pressure building into our area from the west which will help squash the H5 ridge a bit more to the south compared to where it’s been the last day or so. A risk for a few showers or thunderstorms could linger Tomorrow mainly in Northwest Wisconsin and possibly Pine County Minnesota…Otherwise dry weather is anticipated during this period with lowering humidity and very pleasant temperatures. Highs Wednesday will be in the 70s and 80s with lows Wednesday Night in the 50s and 60s. Look for west, southwest, or northwest winds at 10-20 mph during this period.

(Extended Forecast)

High pressure will remain in control of our weather Thursday and Thursday Night which will cause clear-partly cloudy skies with mild temperatures and tolerable humidity. Highs Thursday will be in the 70s and 80s with lows Thursday Night in the 50s and 60s. High pressure pushes east of our area Friday making way for the next low pressure system and cold front which look to pass through our area sometime Friday Night or Saturday. This system could produce another round of showers and thunderstorms and a possible severe weather threat later this week. High temperatures on Friday will be in the 70s and 80s but some 90s are possible in southern areas. Lows Friday Night will be in the 50s and 60s.

It should be noted that the longer range forecast models are beginning to show a possible pattern change which would put our area back in a Northwest flow aloft or basically the same old pattern we’ve been locked into for the most part since last Winter. This pattern change may take place later this weekend and it could last for a while if it does occur since it seems like once we get into a northwest flow aloft it doesn’t really wanna break down for quite some time. That’ll be something to keep an eye on during the next few days.

5 Day Forecast for Duluth/Superior

*Severe Thunderstorm Watch* number 500 remains in effect until 8 PM CDT This Evening…

.Tonight… Humid. Partly to mostly cloudy. Showers or thunderstorms possible through about Midnight. A few storms could become severe with large hail and damaging winds. Low 58 to 63. Wind southwest becoming west to northwest at 10 to 15 mph. Variable winds becoming west at 10 to 15 mph during the night closer to Lake Superior. Chance of rain 30%.
