Weather Synopsis for northeast Minnesota and northwest Wisconsin

Finally dried out today with abundant sunshine over the Northland with mild high temperatures in the upper 50s to low/mid 60s with slightly cooler temperatures closer to Lake Superior.

Quiet and dry tonight with lows in the 30s to lower 40s; mainly clear skies are expected.  Saturday will feature sunny to mostly sunny skies with increasing cloudiness from north to south during the afternoon-evening hours thanks to a cold front which will drop S/SE through the Northland.  This front could produce a few rain or snow showers in northern Minnesota Saturday night.  Temperatures on Saturday will be on the mild side with highs generally in the upper 50s and 60s.

Colder temperatures move in for Sunday as tomorrow afternoon's cold front reaches southern Minnesota while high pressure to our NW allows for a chillier airmass to filter into our area.  There is also a threat for some precipitation on Sunday, and this precipitation could be in the form of snow or rain with light snowfall accumulations possible in parts of the area.

Next week still has potential to turn stormy at times -- The first system will affect the area Monday-Tuesday with scattered rains while far northern Minnesota sees snow or a rain/snow mix.  Two more storms could affect the Northland sometime during the April 27th-30th time frame -- Rain or snow is possible with those systems later next week/next weekend depending on their tracks and the thermal profile of the atmosphere.
