Weather Summary for NE Minnesota & NW Wisconsin
Date:  May 29, 2016

An upper level low pressure system is moved east/northeast and out of the Northland this afternoon but right on its heels was an upper level disturbance which dropped southeast into the Upper Midwest. Cold air aloft combined with daytime heating helped to develop spotty showers in our area today with somewhat steadier rainfall occurring in extreme northeast Minnesota closer to the center of the upper low.  High temperatures today were in the 60s with 70s south of Highway 2 thanks to more sunshine compared to areas farther north.  Winds today were out of the west or northwest at 10 to 20 mph with higher gusts.

Forecast Discussion for NE Minnesota & NW Wisconsin

Confidence:  High.

Tonight:  Any leftover spotty showers will end by 9 PM.  Dry overnight with patchy fog.  Partly to mostly cloudy skies are expected with lows in the 40s and 50s.  Winds out of the west or northwest will turn more out of the southwest later in the night, wind speeds generally in the 5 to 15 mph range.

Memorial Day:  Nice! A weak boundary will be over northern Minnesota on Monday and there is a chance that a few spotty showers will develop Monday afternoon mainly over northern Minnesota.  Mostly sunny skies but some cumulus clouds will likely develop during the late morning and afternoon hours.  Highs are forecast to be in the 70s to lower 80s with west or southwest winds at 10 to 20 mph.

Changes take place Monday night as moisture surges north out ahead of the next area of low pressure which moves east out of the northern Plains -- Showers and a few thunderstorms should overspread the Northland from southwest to northeast Monday night with lows in the 50s with 40s near Lake Superior.  Winds will shift to an easterly direction tomorrow night at 10 to 15 mph with higher gusts around Lake Superior.

...Looking ahead...

Confidence:  Medium to High.

Occasional rain and possibly a few thunderstorms across the Northland on Tuesday as an area of low pressure, warm front and cold front move through the Upper Midwest.  Gusty east winds and probably some fog and drizzle around Lake Superior on Tuesday with highs only in the 40s.  Inland areas will have highs in the 50s and 60s with 70s possible in far southern parts of the area.

A risk for scattered showers will continue on Wednesday as low pressure at the surface and aloft continue to move across the Upper Midwest and western Great Lakes.  Highs on Wednesday will be in the 60s with 70s possible in eastern Minnesota and northwest Wisconsin.
