| Episode Narrative | This winter storm was the first, widespread storm to affect south-central and Southeast Wisconsin during the 20009-10 winter season. Low pressure strengthened as it moved northeast from the Oklahoma Panhandle across Missouri and western Illinois on Tuesday December 8th, then across northern Illinois and southern Lake Michigan to northern Lower Michigan on Wednesday December 9th. This is a favorable track for heavy snow for southern Wisconsin. Observers recorded widespread 12-inch snow totals, with local 16 to 20 inch amounts. The maximum storm total snowfall reported was 20.2 inches near Mc Farland in Dane County (CoCoRaHS). Snowfall amounts were reduced to between 2 and 6 inches along the Lake Michigan shoreline as a combination of warm air drawn northward ahead of the low and warmer air over the lake turned the precipitation over to rain for a time. Additionally, rapid deepening of the low (a 15-mb fall in less than 12 hours) generated sustained winds of 17 to 26 knots (20 to 30 mph) and occasional gusts of 30 to 37 knots (35 to 43 mph) out of the northeast. This resulted in occasional near-whiteout conditions in open areas due to blowing and drifting snow. The somewhat moist snow and the winds combined to knock down trees and power-lines. At the height of the storm, 32,000 customers in the Madison area and 50,000 customers in the metropolitan Milwaukee area were without electrical power. Maximum snow amounts in each county include an estimated 16 in northwest Marquette County, 13.8 in Berlin (Green Lake Co.), 13 in Ashford (Fond du Lac Co.), 13 in Elkhart Lake (Sheboygan Co.), 16.6 in Reedsburg (Sauk Co.), 16.5 near Doylestown (Columbia Co.), an estimated 15 inches in far western Dodge County, 16 in West Bend (Washington Co.), an estimated 12 in far northwestern Ozaukee County, an estimated 14 in fare southeastern Iowa County, 20.s near McFarland (Dane Co.), 14 in Waterloo (Jefferson Co.), an estimated 10.5 in far southwestern Waukesha County, an estimated 6.5 in far southeastern Milwaukee County, 14 in northern Lafayette County, an estimated 18 in northeastern Green County and northwestern Rock Counties, an estimated 10.5 in far north-central Walworth County, an estimated 9 in far northwestern Racine County, and 5 in far western Kenosha County. |
