Forecast Discussion for Northeast Minnesota and Northwest Wisconsin

Today's Weather:

A pair of low pressures one to our northwest and one to our southwest of 1000-1002mb with a trough connecting the two lows has been generating some radar echoes across our area Today, but with quite a bit of dry air in place the majority of this precipitation has not been reaching the ground.  Skies Today were partly to mostly cloudy with high temperatures in the 40s with a few 50s in the Pine River and Brainerd areas.  Winds Today were out of the south or southwest under 20 mph.

Today's Upper Level Analysis:

West-northwest 500mb flow was in place across the Upper Midwest with couple of disturbances riding up and over a strong jet stream >140 knots which covered the Northern Rockies, Northern Plains, and portions of the Upper Midwest per RUC model analysis.

Tonight:

Partly to mostly cloudy skies will continue with a few rain showers possible especially during the Evening.  There might be a few flakes of snow that mix in with these light showers, mainly in the Arrowhead of Minnesota.  Lows Tonight will be in the 20s to lower 30s with south, west, or east winds under 15 mph.

Wednesday and Wednesday Night:

Another disturbance or two will pass by to our south on Wednesday, there could be a few showers mainly in southern parts of our area on Wednesday, otherwise this period looks mainly dry.  Highs Tomorrow will be in the 40s to around 50 degrees, but it will be cooler near Lake Superior.  Lows Tomorrow Night will be in the 20s and 30s.  Winds will be out of the south, east, or north under 20 mph.

Extended Forecast:

A wave of low pressure will head E/NE out of the Central Plains for Thursday and Friday, most of the rain associated with this system should remain to our south, so both Thursday and Friday look mainly dry across Northern Minnesota and Northwest Wisconsin, highs will be in the 40s and 50s, but it will be cooler near Lake Superior.  Lows Thursday Night and Friday Night will mainly be in the 30s.  A powerful surface low and upper level trough are forecast to lift northeast into the Plains this weekend, this system has the potential to produce some rain in our area from Saturday Night through Monday, but how far north this storm tracks is still up in the air at this time and if it stays more to the south, then we may not see much in the way of rainfall in our area this weekend and early next week.
