You wouldn’t really know it, but there actually is a strong fall storm affecting the Northland today, but due to the track of this system (thru the Dakotas) our area is being impacted by that dreaded dry slot. End result from this is for a few bands of quick moving rain showers (lasting a few hours at most) moving across our area which is followed by a drying trend, while a steadier, widespread, and much heavier precipitation event occurs on the north/west side of the area of low pressure (North & South Dakota).

Scattered showers continue to lift quickly to the north across northern Minnesota and northwest Wisconsin late this afternoon.
Scattered showers will come to an end by late this evening/overnight.
Rainfall totals in our area certainly came in on the low side compared to what the computer models were showing for today. Computer models were generally showing totals of 0.25-0.50″ in northeast Minnesota today, and from around 0.10-0.25″ in northwest Wisconsin.
