Weather Synopsis for northeast Minnesota and northwest Wisconsin

A very chilly late April day across the Northland with widespread wintry precipitation this morning which led to slippery/slush covered roads -- Late this afternoon we're seeing an area of snow and mixed precip continuing to affect extreme northeast Minnesota while elsewhere over the Northland there were scattered areas of snow or mixed precipitation, most notably near the head of Lake Superior where some lake effect precipitation has formed late this afternoon.

Low pressure was centered north of Green Bay, Wisconsin as of 4 PM today, this low will lift N/NE and be centered just northeast of Lake Superior by Thursday evening.  An upper level low/trough will move across the upper Midwest during the next 24 hours...This entire system will become negatively tilted as it lifts through the Great Lakes.  Lingering snow, sleet and freezing rain is forecast over parts of the Northland through Thursday evening although precipitation rates should be lighter compared to what occurred earlier today -- The main impacts with some additional snow and or ice accumulations through Thursday evening are forecast to be over extreme northeast Minnesota and over eastern sections of northwest Wisconsin.

A very chilly airmass will be over our area into Thursday as 850mb temperatures drop to around -10 to -15 C.  Lows tonight will be in the teens and 20s with highs Thursday only in the 30s with 20s possible in far northern Minnesota.

It'll warm up Friday with highs getting into the 40s, possibly around 50 degrees but this will still be below average, although warmer than it has been recently.

The big story by late this weekend will be a potential winter storm that may hit portions of the Northland.  Low pressure is forecast to lift N/NE out of the southern Plains over the weekend, if this system comes far enough to the north, it will bring a swath of accumulating snow to parts of northeast Minnesota and northwest Wisconsin sometime between Sunday and Monday.  Note:  There is still a chance this system will track farther south/east than what the computer models have been showing recently, and this would reduce the potential for snow in our area.

Forecast for Duluth and Superior

.Tonight...  Scattered snow showers.  Patchy freezing drizzle possible.  Overcast.  Low 21 to 26.  Wind north at 10 to 20 mph.

.Thursday...  Mostly cloudy.  Cold! Flurries possible.  High 30 to 34.  Wind northwest at 10 to 20 mph.  Note:  Coldest high temperature on record for April 27th at Duluth is 32 degrees set in 1950; 2nd coldest is 33 degrees set in 1908; 3rd coldest 34 degrees set in 1969.
