Forecast Discussion for Northeast Minnesota and Northwest Wisconsin
Low pressure which brought the rain and snow to our area Friday Night and This Morning has moved into Western Quebec Province late This Afternoon with high pressure centered in Western Nebraska. Skies were mostly cloudy Today with spotty instability showers moving southeast through Northern-Northeast Minnesota. Highs Today were mainly in the 40s, but a few locales were close to 50 degrees This Afternoon. Winds were out of the north or northwest under 15 mph.
Today's Upper Level Analysis:
A west-southwest 500mb flow was in place from the Southern Rockies through the Central Plains and Northeast U.S. while a west-northwest H5 flow stretched from the Northern Rockies to the Upper Midwest. An upper level trough covered the Pacific Northwest per water vapor satellite imagery with several disturbances heading E-NE through the Southern Rockies to Ohio Valley.
Scattered showers will end by mid-Evening. Partly to mostly cloudy skies will be found in our area Tonight with lows mainly in the 30s. Winds will be out of the north or west under 15 mph.
Easter Sunday and Sunday Night:
High pressure will head east out of the Western High Plains with a milder southwest wind developing in our area. Highs on Sunday will be in the 50s to lower 60s with lows Sunday Night in the 30s to around 40 degrees. Partly to mostly sunny skies are forecast Tomorrow with the possibility for a few Afternoon showers in Northern Minnesota. Sunday Night will be dry with partly cloudy skies. Winds will be out of the southwest at 10-20 mph during this period.
Monday and Monday Night, April 25th: Looks dry in our area with a stationary front off to our north while low pressure develops in the Southcentral Plains. Highs on Monday will be in the 50s and 60s, but it will be turning cooler near Lake Superior as onshore winds develop. Lows Monday Night will be in the 30s to lower 40s.
Tuesday and Tuesday Night, April 26th: Model differences continue during this period with the track of a low pressure system. The GEM-GLOBAL, UK, and EURO models are farther west-north with this system which would result in rain spreading into Northwest Wisconsin and Northeast-Eastern Minnesota Tuesday Afternoon through Tuesday Night. The GFS is farther south-east which would keep most of our area dry. Highs on Tuesday will be in the 40s and 50s with 30s near Lake Superior. Lows Tuesday Night will mainly be in the 30s. Note: Strong E-NE winds could develop during this period near Lake Superior, especially if this low takes the northern route. A few of the models during the past few days have shown 850mb wind speeds increasing to 40 to 60 knots on Tuesday which would result in wind gusts >35 mph.
Some lingering showers are possible Wednesday and Thursday, April 27th-28th as an upper level trough pushes slowly east across the Upper Midwest. It does appear that the secondary low which will develop in the Southern Plains on Wednesday will track too far east to give us any rain or snow for mid-week.
