Forecast Discussion for Northeast Minnesota and Northwest Wisconsin

Today's Weather:

A day similar to Friday with below normal temperatures, lots of sunshine for inland areas while scattered lake clouds, snow showers/flurries persisted at times near Lake Superior.  The snow showers reduced visibility for very brief periods of time, but accumulations have been extremely light or non-existent.  Highs Today were in the middle 20s to lower 30s with temps in the Arrowhead right around 20 degrees.  Winds Today were out of the north or east at 5-15 mph with a few higher gusts near Lake Superior.  Surface map This Afternoon featured a few areas of high pressure averaging 1030mb stretching from Central Canada to the Upper Midwest.

Today's Upper Level Analysis:

North-northwest 500mb flow was locked in place over the Upper Midwest which will detour any systems moving into the Western U.S. to our south into the middle of next week.  A cold airmass covers much of the Great Lakes, Northern Plains, and parts of the Central Plains with Afternoon 850mb temperatures ranging from -6 degrees C at Aberdeen, South Dakota; -4 degrees at Kansas City; -10 degrees C at Chicago; and -13 degrees C at Duluth.

Tonight through Sunday Night:

High pressure will remain in control of our weather during this period with clear to partly cloudy skies.  Lows Tonight and Sunday Night will be in the single digits below to lower teens above zero with a few Northern Minnesota locales possibly dropping to the teens below zero.  Highs Tomorrow will be in the 20s to lower 30s.  North or east winds will continue under 15 mph.  Scattered lake effect clouds, snow showers/flurries will linger at times through Sunday Night near Lake Superior, but no major accumulation is expected.

Extended Forecast:

High pressure is locked in place and will continue to our area dry and quiet into the middle of next week.  Monday and Tuesday's high temperatures will be in the 20s and 30s, it's not out of the question that a few locales could sneak toward 40 by next Tuesday (which is right around average for this time of year) Low temperatures Monday Night and Tuesday Night will be in the teens.  Models continue to show some sort of a clipper system moving into the Upper Midwest late next week, Thursday-Friday, April 1st-2nd time frame, this system doesn't look very impressive at the moment, but it could bring some rain and or snow showers to our area as it moves through.
