Regional Weather View.

It is turning out to be an active week in the Upper Midwest. Something I have not had to say in a long time. Attention is turned to our next weather producer which will spread thunderstorms across Illinois tonight, and significant snow accumulations to parts of Iowa, Far southeast Minnesota and parts of Wisconsin. A cold arctic airmass is waiting to move in behind this storm on strong northwest winds. The entire region will be plunged into this aissmass as the low moves away. The cool airmass will also keep things fairly dry. Temperatures will begin to moderate though the weekend.

Parts of our area will be dealing with a winter storm, but because of the way this storm is shaped only the eastern parts will have this take place. Late tonight as a low pressure system moves from Missouri to Illinois snow will spread northeast through Iowa and into Southeastern Minnesota. A cold front will also sweep in from the northwest. The far western extend of the system will effect our area. Eastern Fillmore and Winona counties will see the heaviest and brunt of the accumulating snows Winona, Harmony, Lanesbro are just a few of the coummunties which stand the best chance at seeing winter storm value accumulations. There will be a sharp cut off, Further west 2-4" are possible including Preston, St Charles and Wabasha. West of here 1-2" are possible effecting Rochester, Austin and Lake City. North and west of here will just see flurries. Blowing snow and free falling temperatures will be a problem as winds gusting up to 40MPH at times bring in an arctic airmass from the northwest. Temperatures will fall into the single digits late Wednesday and below zero Wednesday Night. 

Brunt of arctic airmass in place by Thursday.
For Thursday the brunt of the arctic airmass will be in place. It will also be breezy with cold wind chills making it feel colder.
