Forecast Discussion for Northeast Minnesota and Northwest Wisconsin

Today's Weather:

Another very nice early spring day across the area with plenty of sunshine and just a few passing mid and high level clouds.  Highs Today were generally in the 40s, except for some 30s closer to Lake Superior.  Winds were light and variable under 12 mph.

Today's Upper Level Analysis:

Blocking pattern as of late is starting to break down as a very potent 150+ knot upper level jet blasts southeast out of Western Canada through the Northern-Central Rockies/Western High Plains per RUC model analysis.  This is helping to erode the persistent H5 trough which had been over Central Canada and the Upper Midwest during the last few days.

Tonight:

Partly to mostly cloudy skies will be found in our area with high pressure centered just off to our east.  Lows will be in the teens and 20s with south or southeast winds under 15 mph.

Thursday and Thursday Night:

Should have less sunshine Tomorrow compared to previous days as a low pressure trough heads east through the Northern Plains.  Southerly winds will be in place out ahead of this system which will draw some moisture north into the Upper Midwest.  Most of Tomorrow looks dry for our local area, but some rain or snow showers could develop by mid or late Afternoon generally west of an International Falls to Brainerd line.  By Thursday Night, the risk for some rain and or wet snow will increase from west to east as a trough of low pressure moves into the Upper Midwest.  Highs Tomorrow will be in the 30s and 40s with lows Tomorrow Night in the 20s and 30s.  Winds will be out of the south or east under 20 mph during this period.

Extended Forecast:

Low pressure will continue to move south/east on Friday, this system should reach the Southern Great Lakes by Friday Evening.  Some additional wet snow and or rain will likely be found in Northern Minnesota and Northwest Wisconsin on Friday before mainly dry conditions return for Friday Night through Saturday Night. 

Note:  Precipitation totals should be under 0.25" from Thursday Afternoon through Friday Afternoon with snowfall accumulations of 1" or less, although a spotty 2" total is not out of the question...But those should be few and far between.

Highs for Friday and Saturday will be in the 30s and 40s with lows Friday Night and Saturday Night in the 20s.

Mainly dry conditions should continue for Northern Minnesota and Northwest Wisconsin from Sunday through Tuesday, April 3rd-5th...There will be a storm system crossing the Rockies this weekend before it pulls out into the Central Plains/Southern Great Lakes/Ohio Valley areas early next week, right now it looks like the bulk of the precipitation (rain or snow) would remain to our south, although the area along and south of a line from Brainerd to Hinckley to Hayward and Park Falls could see some snow or rain from Sunday through Monday, but it doesn't look like it would be a very big deal at the moment.
