Forecast Discussion for NE Minnesota and NW Wisconsin
Confidence: Medium to High.
Tonight: A frontal boundary over northern Minnesota late this afternoon will settle a little bit to the south tonight while low pressure remains over the northern Plains. Southerly flow ahead of this system will allow moisture to flow north into the Upper Midwest tonight which will help to generate showers and isolated thunderstorms. Low temperatures will be in the 40s and 50s with lower 60s in far southern-western parts of the Northland. Winds will shift to the south or east at 10 to 20 mph with higher gusts around Lake Superior.
Tuesday: Cold and damp near Lake Superior with highs only in the 40s and 50s along with strong east winds in the 15-30 mph range. For areas away from Lake Superior expect highs to top out in the 50s and 60s with 70s in far southern portions of the area. Lows will be in the 40s and 50s with lower 60s in parts of northwest Wisconsin.
Low pressure along with a warm front and cold front will head into the Upper Midwest on Tuesday which will cause occasional rain and isolated thunderstorms to develop across the Northland -- PWATS ranging from 1.00-1.50"+ will result in locally heavy downpours.
Not much of a threat for severe thunderstorms tomorrow with mostly weak instability in place although if an isolated stronger thunderstorm were to develop it would likely be over northwest Wisconsin and or east central Minnesota.
A few lingering showers will be possible on Wednesday as a surface and upper level area of low pressure continue to affect the Northland's -- This system exits to the east on Thursday which should result in mainly dry weather in our area.
Rain chances return Friday, Saturday and Sunday as the flow aloft shifts more out of the NW which should allow for a couple of disturbances to drop south/southeast into the Upper Midwest and western Great Lakes region, this will cause scattered showers and possibly a few thunderstorms to develop late this week and during the upcoming weekend. Not a total washout over the weekend but scattered showers can't be ruled out.
Daytime highs are expected to be in the 60s and possibly a few 70s from Wednesday through Sunday with cooler temperatures at times near Lake Superior especially on Friday, Saturday and Sunday.
