Weather Synopsis

A very cool airmass was over the Northland today.  Late afternoon meso-analysis revealed 500mb temperatures of -22 to -25C with 850mb temperatures from +3 to +5C.  Daytime highs today were only in the 50s to lower 60s while a few locations in far northeast Minnesota had temps in the upper 40s this afternoon.  Persistent NW flow aloft brought another disturbance down into our area today although today's system tracked farther north compared to Saturday's.  Rain was widespread most of the day in far northeast Minnesota while occasional showers were common over most of the rest of the Northland.  Winds were a bit gusty today out of the northwest with wind speeds in the 10 to 25 mph range.

Rain will continue most of the night in far northeast Minnesota along and east of a line from near Forest Center, Isabella and Silver Bay.  A few showers will also occur west/south of those areas in northeast Minnesota and northwest Wisconsin but this activity should taper off by later this evening with mainly dry weather expected for these areas overnight.  Could be some patchy fog late tonight otherwise partly to mostly cloudy skies with cool low temperatures in the 40s, maybe even some 30s up north if skies clear out enough.

Turning a bit warmer but still slightly cooler than normal for Monday with highs in the 60s to lower 70s under partly to mostly sunny skies -- A few pop up afternoon showers or thunderstorms in parts of the Northland as well.

Tuesday still looks to be one of the nicer days this week with a mix of sun/clouds along with a breeze out of the SW -- Highs Tuesday mainly in the 70s (Normal for late June)

Cooler temps return midweek along with chances for rain and perhaps a few thunderstorms.  Low pressure moving east out of the northern Plains along with a warm front and cold front will lead to these rain chances for Wednesday.  Higher moisture content also moves in with PWATS over 1.25" this could lead to some heavier downpours in parts of the Northland for Wednesday.

.Tonight...  Spotty showers before midnight.  Partly to mostly cloudy.  Low 45 to 50.  Wind northwest at 10 to 20 mph.
