Wisconsin Snow Returns - Power Outages Reach 20,000

Nov 09, 2011
Central Wisconsin experienced the first snowstorm of the 2011-2012 season today. A panhandle type storm system moved northeast from southwest Missouri to southern Lake Michigan bringing rain, snow and strong winds. Winter storm warnings were issued for central and northeast Wisconsin, while winter weather advisories were issued across south central Wisconsin. The snow was heavy for most of the day with reports of Thundersnow in Green Bay. Snowfall totals have been ranging between 3-9 inches with heavier amounts to the north.

The water vapor image and 500mb height map shows a strong vort max moving northeast through Iowa, Illinois and Wisconsin. The surface map indicates a strong pressure rise/fall couplet moving over Lake Michigan. This difference in pressure produces strong winds within this region due to the strength of the deepening low and the 500mb disturbance.

The storm system is still ongoing across northeast Wisconsin and the final snow totals won't be official until later tonight. According to twitter feed reports (#wiwx) from the Green Bay Gazette power outages have occurred well over 20,000 in Stevens Point, Antigo, Rhinelander amongst other areas across the state.
