Tuesday through Thursday (April 5-7)

A sloppy Tuesday and Wednesday on the way as low pressure tracks south/east out of the Northern Plains -- Wet snow and rain and possibly some sleet will spread across the Northland on Tuesday with lingering precipitation expected from Tuesday night through Wednesday.  Note:  A few inches of slushy snow is looking more and more likely especially along and north/east of Highway 2, the best chance for this snow accumulation appears to be from Tuesday afternoon into Tuesday evening, this is when the heaviest band of precipitation passes through the area.
