Weather Summary for NE Minnesota and NW Wisconsin
Date: July 26, 2016
Warm and muggy conditions in the Northland today as high temperatures topped out in the 80s with dew points in the 60s with even a few locations in northwest Wisconsin and east central Minnesota up around 70 degrees this afternoon. Winds were out of the north, west or south at 5 to 15 mph. Late this afternoon a cold front extended from west central into northeast Minnesota. Scattered showers and a few thunderstorms have been developing near this boundary this afternoon but these storms have not been able to hold together very long before they fall apart.
Forecast Discussion for NE Minnesota and NW Wisconsin
Tonight (July 26)
A cold front in northeast Minnesota late this afternoon will move slowly south/east tonight while high pressure builds south over Manitoba Province.
Scattered showers and thunderstorms are possible tonight mainly near and south of Highway 2, affecting east central Minnesota and most of northwest Wisconsin. It is quite unstable late this afternoon with mesoanalysis showing CAPE ranging from 1500-3000 j/kg along with lifted indices of -3 to -8 degrees Celsius. Winds aloft are quite weak though, and there isn't much of a low level jet either so this could be part of the reason why storms have had a tough time developing/sustaining themselves this afternoon despite the favorable amount of instability and moisture that is available for storms. The amount of instability will diminish during the night which is typical after sunset but there should still be enough for continued scattered thunderstorm coverage through the night, again mainly affecting east central Minnesota and northwest Wisconsin.
Locally heavy rain and cloud to ground lightning will be the main hazards from thunderstorms tonight with a risk for hail and strong winds this evening south of Highway 2.
Lows will be in the 60s with 50s in northern Minnesota. Winds will shift to the north or east at 5 to 15 mph.
Wednesday (July 27)
Breezy and cooler around Lake Superior as east winds increase to 10 to 20 mph with gusts to 25 mph with highs around 70 degrees. Inland locations will have highs in the 70s to lower 80s.
Occasional showers and scattered thunderstorms are possible in parts of the Northland on Wednesday with drier conditions returning from north to south for Wednesday night.
Mostly cloudy skies tomorrow with winds out of the north or east at 10 to 15 mph. Mostly cloudy to partly cloudy tomorrow night with winds out of the east or northeast at 5 to 15 mph, low temperatures will be in the 50s to lower 60s.
High pressure passing north of our area late this week should result in mainly dry weather across the Northland for Thursday and Friday. High temperatures are expected to be in the 70s to around 80 degrees with cooler temperatures around Lake Superior as northeast winds continue late this week.
