Detailed forecast

Fri Dec 2, 2022 - The arctic cold front has begun to work across MN with a temperature of 3 at Hallock and 46 at LaCrosse this hour. The front will gradually continue to work southeastward today. Surface convergence ahead of the front will continue, and following the front strong winds will occur. Kept the Yellow (Moderate) for southwestern MN due to blowing dust possibilities but kept the rest of the state in Green (Good). Green (Good) is forecasted for the rest of the weekend as temperatures plummet. The source region of the airmass is in the Green (Good) category and should continue. There may be a couple hours of Yellow (Moderate) in the early morning, which is commonly seen early in the season with bitterly cold temperatures due to the exhaust from furnaces and other heating elements getting caught in the boundary layer. Those should mix out by afternoon each day and Green (Good) AQI is forecasted statewide.
