Weather Summary for NE Minnesota and NW Wisconsin
Date:  June 20, 2016

A much quieter day in terms of no severe weather but still on the windy side with gusty west winds at 15 to 30 mph.  Highs were in the 70s with much drier air over the area this afternoon with dew points only in the 30s and 40s which is a far cry from 24-hours ago when dew points ranged from 65 to around 75 degrees.  Sky conditions were mostly sunny to partly sunny with just some fair weather cumulus clouds passing quickly to the southeast today.

Forecast Discussion for NE Minnesota and NW Wisconsin

Confidence:  High.

Tonight:  Pleasantly cool under clear to partly cloudy skies.  Lows in the 50s with 40s possible in the typical cold spots.  Winds will remain out of the west at 10 to 20 mph, higher gusts this evening.

Tuesday:  Dry under partly cloudy skies.  Highs mainly in the 70s with west or northwest winds at 10 to 20 mph which will gradually turn out of the east later Tuesday night.  High pressure will be in control of our weather during the next 24 hours as it slowly builds into the Upper Midwest.

...Extended Forecast...

Confidence:  Medium to High.

Showers are possible from Wednesday into early Thursday morning as low pressure moves east out of the western High Plains -- Not looking at any thunderstorms with this system in our area as the airmass should be fairly stable the way it looks now.  Highs on Wednesday will be in the 60s and 70s.

The weather should improve again on Thursday with highs in the 70s along with a wind shift from the east on Wednesday back to the west for Thursday.

Stormier weather is possible during the Friday evening through Saturday night time frame as a rather strong area of low pressure tracks northeast out of the northern Plains -- This low combined with a warm front and cold front moving into the Upper Midwest could produce showers and thunderstorms across parts of the Northland Friday night into Saturday.  Early indications are for enough moisture, instability, heating, wind shear and stronger winds aloft to be in place which could lead to a few strong to severe thunderstorms especially on Saturday the way it looks now.
