Forecast discussion for Northeast Minnesota and Northwest Wisconsin

Today's weather:

Light rain and drizzle ended from northeast to southwest as dry air advected into the area around a strong 1032mb surface high which was located in Western Manitoba Province.  Overcast skies during the Morning gave way to decreasing afternoon cloudiness for most areas.  Highs Today were in the 50s to lower 60s with the mildest temperatures found in Northern Minnesota, cooler 40s were common in Downtown Duluth and Superior, east along the South Shore of Lake Superior.  Winds Today were out of the north or east at 10-20 mph with gusts over 30 mph near Lake Superior.

Today's upper level analysis:

500mb low was nearly stationary across the Southern Great Lakes/Ohio Valley region early This Evening per water vapor satellite imagery.  An odd east to west H5 flow was occurring across the Upper Midwest Today as the atmosphere becomes blocked up and amplified.

Tonight through Sunday Night:

High pressure will be in control of our weather during this period with clear to partly cloudy skies.  Low temperatures Tonight and Sunday Night will be in the 30s and lower 40s, but a few 20s cannot be ruled Sunday Night in Northwest Wisconsin and Eastcentral Minnesota.  A threat for patchy frost does exist especially for Sunday Night.  Highs Tomorrow will be in the 50s and 60s, but it will be cooler near Lake Superior.  North or east winds are expected during this period at 5-15 mph with a few higher gusts near Lake Superior.

Extended Forecast:

A quiet weather pattern will continue for our area from Monday through Wednesday, May 16th-18th.  High temperatures for Monday and Tuesday will mainly be in the 60s, but it will stay cooler near Lake Superior.  Lows Monday Night and Tuesday Night will be in the 30s and 40s.  An upper level system off to our east will try to push back toward the west sometime the middle or end of next week, this system combined with another one which will head into the Southern-Central Plains late next week/next weekend could lead to some rain showers spreading north into the Upper Midwest from next Thursday through Sunday, May 19th-22nd.
