Forecast Discussion for Northeast Minnesota and Northwest Wisconsin

Today's Weather:

Low pressure of 1005 mb was centered in the Southwest half of Wisconsin (between Arcadia and La Crosse) late Today with a a secondary low averaging 1008 mb just north of Minneapolis Minnesota. A warm front was over across Southern Wisconsin This Afternoon where temperatures in the 80s and dewpoints in the upper 60s/mid 70s along with strong southerly winds were in place Today while a cold front was sinking south through Southern Minnesota. The large complex of heavy rain and embedded thunderstorms which tracked northeast through all of Northwest Wisconsin, Eastcentral and Northeast Minnesota Today has exited to our E/NE late This Afternoon with just some pockets of light rain and drizzle lingering in portions of Northeast Minnesota and Northwest Wisconsin late Today. A very moist airmass was in place across our area Today with PWS as of 3 PM ranging from 1.30"-1.50" with 850 mb td's of +8/+13 degrees C. Overcast skies and unseasonably cool temperatures were found in our area Today with highs only in the mid 50s to lower 60s with upper 40s common at the head of Lake Superior. 850 mb temperatures as of 3 PM ranged from +8/+14 degrees C across Northeast Minnesota and Northwest Wisconsin. Winds Today were out of the north or east at 5-15 mph, but much stronger winds of 15-30 mph with gusts up to 40-50 mph did occur near Lake Superior. Note: There have been a few reports of downed trees and power lines in Duluth Today due to the high winds.

Today's 500 mb analysis:

Southwest flow aloft covered the Upper Midwest Today per water vapor satellite imagery. Upper level ridge covered the Southern-Eastern U.S. with an upper level trough across the Western U.S. Unusually strong upper level winds (100-120 knots) extended from Central Oregon to Central California with another area of strong upper level winds (110-130 knots) over parts of Northern Ontario Province through Central Quebec Province per RUC model analysis. An upper level low (588 meters) was tracking northeast through Eastern Missouri/Southwest Illinois Today per water vapor satellite imagery/RUC model analysis. This warm-core system has been responsible in the flooding rains that have occurred during the past few days in portions of Texas and Arkansas. Note: As many as 10 deaths were reported in Arkansas Thursday Night due to the flooding.


Areas of drizzle could linger most of the night, especially near Lake Superior where some fog is also possible. The rest of our area should be mainly dry Tonight, but a few showers can't be ruled out in Southern areas. Mostly cloudy skies will cover our area Tonight with patchy fog possible. Lows Tonight will be in the 40s and 50s with north or east winds at 5-15 mph with gusts to 30 mph continuing especially This Evening near Lake Superior.

Saturday and Saturday Night:

A stationary front will be centered well to our south-southeast through Tomorrow Night. Another low pressure disturbance is forecast to track E-NE out of the Rockies and across the Upper Midwest during this period. Another round of rain-showers should develop and spread E/NE into parts of Northeast and Eastcentral Minnesota and Northwest Wisconsin Tomorrow and Tomorrow Night, although rain amounts Tomorrow should be much less compared to what we saw Today. Rain should end from west to east Saturday Night the way it looks now. Partly sunny-mostly cloudy skies are expected on Saturday with highs in the 50s and 60s. Partly-mostly cloudy skies are forecast for Saturday Night with lows in the 40s and 50s. Winds during this period will be out of the north or east at 5-15 mph.

Extended Forecast:

The frontal boundary currently over Southern Minnesota will sag south into the Central Plains this weekend while an upper level trough approaches the Upper Midwest from Central Canada. At this time it appears that Sunday and Sunday Night will be generally free of any rain, although a few showers can't be ruled out in Northern and Southeast parts of our local area. A slight chance for showers will also exist for Monday and Monday Night across Northern Minnesota and Northwest Wisconsin. High temperatures Sunday and Monday will be in the 50s and 60s with lows Sunday Night and Monday Night in the 40s and 50s.
