Forecast Discussion for Northeast Minnesota and Northwest Wisconsin

Today's Weather:

Chilly high pressure (1034 mb) was centered over Western Minnesota late Today.  Besides some scattered lake effect clouds near Lake Superior in Northwest Wisconsin and some scattered clouds in Northeast Minnesota, skies for the most part were mostly sunny Today with high temperatures ranging from the middle 40s to middle 50s along with the coolest 850 mb temperatures to date with values of zero/-2 degrees C in Northern Minnesota and Northwest Wisconsin Today.  Winds Today were out of the north or east under 15 mph.

Today's Upper Level Analysis:

An amplified pattern covers the U.S. Today with a broad upper level trough covering the Upper Midwest and Great Lakes per RUC model analysis and water vapor satellite imagery...An upper level low covered portions of California and Nevada Today while an upper level ridge was in place across the Central-Southern Rockies.

Tonight through Sunday Night:

Strong high pressure averaging 1032 mb will exit slowly to our south/east during this period.  Mostly clear skies are forecast through Sunday Night with lows Tonight in the 20s and 30s, highs Tomorrow will be mainly in the 50s to around 60 degrees, lows Tomorrow Night will be in the 30s, but some 20s are possible in the typical cold spots.  Areas of frost will occur late Tonight and again late Sunday Night.  Winds will be calm or variable in direction Tonight, shifting to a southerly direction under 15 mph Tomorrow and Tomorrow Night.

Extended Forecast:

A stretch of pleasant early October weather should continue most of next week across our area as cut-off lows remain over the Southwest U.S. while a new one forms over the Eastern U.S.  We will see a cold front try to move into the Upper Midwest around mid-week, although right now it looks like this front will come through dry.  High temperatures will be in the 50s and 60s for Monday and Tuesday with lows both nights mainly in the 40s, although a few 30s are possible Monday Night.
