Forecast Discussion for Northeast Minnesota and Northwest Wisconsin

Today’s Weather:

High pressure centers around 1024 mb were found across the Central Plains and to our southeast in Southern Wisconsin, meanwhile a stronger high of 1032 mb was beginning to build southeast out of Southwest Saskatchewan Province. A cold front was dropping south into Northern Minnesota This Afternoon, but even with this boundary moving in skies stayed mostly sunny Today. High temperatures were in the single digits and teens Today with 850 mb temperatures as of 2 PM ranging from -9 to -13 degrees C. Winds Today were out of the south or west under 15 mph.

Today’s 500 mb analysis:

Northwesterly flow prevailed across the Upper Midwest Today with upper level ridging covering areas from the Northern Rockies into the Central and Southern Plains while another upper level trough covered portions of the Pacific Northwest This Afternoon per RUC model analysis.

Tonight through Sunday Night:

Cold front in Northern Minnesota This Afternoon will drop south through our entire area Tonight with high pressure building back into our area behind this front from late Tonight through Tomorrow Night. Mainly dry conditions will persist in our area during this period with some lake effect snow showers possibly developing in Ashland and Iron Counties in Northwest Wisconsin by Sunday and Sunday Night, snowfall amounts of 1-3″ are possible in those areas by late Tomorrow Night. Lows Tonight will be in the single digits below to above zero with some teens below in Western-Northern areas. Highs Tomorrow will be in the single digits to low teens with lows Tomorrow Night in the single digits, teens, and 20s below zero. Winds from the south or west will become northwest at 10-20 mph Tonight with northwesterly winds continuing Tomorrow and Tomorrow Night under 20 mph.

Extended Forecast:

A rather tranquil weather pattern is expected to continue for our area next week with no organized systems expected at this time. We could, however, see a few minor disturbances pass through the Upper Midwest which could bring some flurries or snow showers to parts of our area sometime during the middle or end of next week, but right now these impulses look fairly weak.

High temperatures on Monday will be in the single digits and teens with mainly teens expected on Tuesday. Lows Monday Night will be in the single digits, teens, and 20s below zero with lows Tuesday Night in the single digits below to above zero.

A moderating trend in temperatures is expected in the Upper Midwest later next week with highs possibly climbing toward 30 degrees toward next Friday or next Saturday.

Forecast Discussion for Northeast Minnesota and Northwest Wisconsin

Today’s Weather:

Arctic high pressure of 1032 mb was centered in Southern Wisconsin This Afternoon while a 1026 mb high was centered in Southwest Saskatchewan Province. High pressure of 1020 mb was centered in Southwest South Dakota with a 1026 mb high centered in Northwest Ontario Province. Needless to say high pressure was in control of our weather Today with mainly sunny skies and cold temperatures. Highs Today were in the single digits and low teens with 850 mb temperatures as of 3 PM ranging from -10 to -15 degrees C. Winds Today were out of the south or west under 15 mph.

Today’s 500 mb analysis:

Northwest flow aloft prevailed across the Upper Midwest Today with a powerful upper level jet of 130-180 knots extending from the Southern and Eastern Great Lakes into parts of the Northeast U.S. Strong upper level low (552 meters) was centered over the Northern Texas/Southern Oklahoma area This Afternoon per RUC model analysis and water vapor satellite imagery with movement toward the east-northeast. This H5 low across the Southern Plains is part of a larger winter storm which is affecting many areas from Oklahoma and Arkansas east through Kentucky, Tennessee, and eventually into the Carolinas and Virginia.

Tonight through Saturday Night:

High pressure will remain in control of our weather through this period. Clear to partly cloudy skies are expected in Northern Minnesota and Northwest Wisconsin Tonight with partly to mostly cloudy skies Tomorrow and Tomorrow Night. Bitterly cold temperatures will occur once again Tonight with lows falling into the single digits, teens, and 20s below zero. Highs Tomorrow will be in the single digits and teens with lows Tomorrow Night in the single digits and teens below zero. The possibility does exist for a few flurries in parts of our area Tomorrow or Tomorrow Night as a trough swings south/east into Northern Minnesota, this chance looks quite low, however. Winds during this period will have a westerly component to them under 20 mph.

Extended Forecast:

Weather pattern continues to look fairly quiet for Northern Minnesota and Northwest Wisconsin from Sunday into Monday, could see a period of lake effect snow showers affect Ashland and Iron Counties in Northwest Wisconsin during this period, but right now this event looks quite light. A reinforcing shot of arctic air will build south/east out of Central Canada late this weekend and early next week with the southwestern flank of that cold pool pushing into our area which will result in more subzero nighttime lows for Sunday Night and Monday Night. A weak disturbance appears that it will pass south/southeast of our local area from late Monday into Tuesday, this system could bring some flurries into Eastern Minnesota and Northwest Wisconsin early next week, but nothing major is expected.

High temps will be in the single digits and teens Sunday and Monday with lows Sunday Night and Monday Night in the single digits and teens below zero, but some of the traditional cold spots could drop into the 20s below zero.

Forecast Discussion for Northeast Minnesota and Northwest Wisconsin

Today’s Weather:

Arctic high pressure of 1036 mb was centered in Northwest Iowa early This Evening with a 1032 mb high centered in Southeastern Saskatchewan Province. This ridge of high pressure resulted in partly cloudy to sunny skies across our local area Today with very cold daytime highs only in the single digits above zero. 850 mb temperatures as of 7 PM ranged from -18 to -25 degrees C with the heart of the coldest air now found over Eastern Ontario Province where -26 to -30 degree C H85 temps were found early This Evening. Winds Today were out of the north or west under 20 mph. The arctic air in place combined with a northwest wind moving across Lake Superior resulted in the formation of some lake effect snow showers Today along the South Shore of Lake Superior in Northwest Wisconsin with new snow accumulations of 1-4″ Today in parts of Bayfield, Ashland, and Iron Counties.

This Evening’s 500 mb analysis:

Northwest flow aloft was in place across the Upper Midwest This Evening per RUC model analysis and water vapor satellite imagery. Polar vortex (504 meters) has moved east into the Eastern Ontario-Western Quebec Province area This Evening with a powerful upper level jet of 120-170 knots extending from Southern Minnesota through the Central and Southern Great Lakes into the Upper Ohio Valley region.

Tonight through Friday Night:

Arctic high pressure will remain in control of our weather through this period. Expect generally partly cloudy skies with very cold temperatures persisting. Lows Tonight and Friday Night will be in the single digits, teens, and 20s below zero with highs Tomorrow in the single digits to low teens above zero. Winds will be out of the north or west under 20 mph during this period. With the arctic air in place and a W/NW wind coming off Lake Superior the potential exists for a few snow showers through Tomorrow Night, mainly impacting Ashland and Iron Counties in Northwest Wisconsin, snow amounts should remain less than 2″ though.

Extended Forecast:

Dry weather will continue across our area this weekend with one high moving away while a new area of high pressure builds in from the north. There will be another surge of arctic air later this weekend that will try to advect southwest/south into our area, although right now it looks like the brunt of that arctic air will remain off to our northeast. High temperatures Saturday and Sunday will be in the single digits and teens with lows Saturday Night and Sunday Night in the single digits and teens below zero.

A minor snow event is still possible for parts of Northwest Wisconsin and Northern Minnesota early next week, but the forecast models Today have trended slightly more to the south and a tad drier with this system, so all in all it looks like a fairly dry weather pattern for our area through the weekend, and perhaps even into early next week.

5 Day Forecast for Duluth/Superior

.Tonight… Bitterly cold. Mostly clear. Low 13 below to 18 below, a little warmer in Downtown Duluth. Wind west under 15 mph. Wind chills approaching 25 below zero.

1/28/2010: Lake Superior Photos

Decided to take a short 15-20 minute drive to Park Point to view Lake Superior This Afternoon on what was a very cold arctic day in Duluth Minnesota, lots of ice/snow hugging the immediate shortline, but quite a bit of open water remains on the Southwestern shore of Lake Superior, usually if were going to see it 100% ice covered, it would’ve happened by now. Could the lack of ice spell a milder Spring in Duluth? Time will tell. Enjoy the pics!
