Forecast Discussion for northeast Minnesota and northwest Wisconsin

.Short Term Forecast...

Tonight (October 8)

Mostly cloudy skies should gradually give way to some clearing during the night.  High pressure will move over the Northland tonight which will promote good radiational cooling if or when skies clear.  Low temperatures will mainly be in the 30s but some locations could drop into the 20s.  Light and variable wind direction at around 10 mph.

Sunday (October 9)

Warm air advection pattern develops on Sunday with 850mb temperatures of 0 to around -3 degrees Celsius this evening climbing to +4 to +12 degrees Celsius from northeast-southwest by Sunday evening.

High pressure moves off to the east while a warm front passes through the Northland Sunday night.  Shouldn't be any precipitation as that warm front moves through.

Partly to mostly cloudy skies are expected on Sunday with highs in the 50s with 40s along the North Shore and over the Arrowhead of Minnesota.  Lows Sunday night will be in the 40s.  Winds will be out of the south or southeast at 10 to 20 mph.

.Extended Forecast...

Monday (October 10)

Dry and mild on Monday with a gusty south-southwest wind.  Highs will be in the 60s to lower 70s which would be 10-20 degrees above average.  The reason for this warmup - Low pressure well to our north with a cold front to our west, this puts the Northland in the warm sector of this system with a gusty/mild southwesterly wind.

A cold front will begin to move into western portions of the area Monday night and that is where some showers could occur, the rest of the area stays dry.  Lows will be in the 40s and 50s.

Tuesday (October 11)

A cold front moves across the Northland with a chance for showers on Tuesday.  Still mild ahead of this front with highs in northwest Wisconsin reaching the 60s to around 70 degrees while northern Minnesota will have highs in the 40s and 50s.
