We’re in for a cool down heading into October!

TODAY: A couple troughs of low pressure will progress through the region today and tonight. Highs reach the mid 50's as strong cold air advection will begin to drive down temperatures into the overnight hours. Winds will be out of the NW at 10-20 MPH, gusting higher at times. We'll see mostly cloudy skies with a 60% chance for scattered showers.

TONIGHT: Lows fall into the 40's in WI and the 30's in MN. Patchy frost will be possible. A 40% chance for scattered showers continues through the overnight, with that chance gradually decreasing towards the mid morning hours. Northern MN has a chance to see mixed precipitation, or even just flurries as we head towards Thursday morning. If this does happen, I don't expect any accumulation as the ground is still too warm.

THURSDAY: Our first day of October features highs in the mid 40's with mostly cloudy skies. We'll see a 20% chance for showers. Skies will gradually become clear heading into the evening and overnight hours as high pressure moves in.

THURSDAY PM: This will likely be our coldest night of the season so far. Lows will dip down into the 20's and teens as clear and calm conditions promote radiational cooling. Widespread frost will be likely. There's even a small chance for some lake effect snow along the South Shore in eastern WI and MI, but this would be brief as winds will calm down into the evening hours before temperatures get too cold.

FRIDAY: High pressure brings mostly clear skies with highs in the mid 40's. Lows dip into the 20's and 30's with partly cloudy skies.


Have a great day!
