||The only January 2010 winter storm of any consequence produced periods of moderate to heavy snow across most of south-central and southeast Wisconsin on January 7th. Total snow accumulations were mostly in the 6 to 12 inch range. This storm was the result of strong forcing associated with a vigorous upper-low that tracked from central Iowa to east-central Illinois and then eastward. The storm had brisk northeast surface winds of 13 to 17 knots (15 to 20 mph) with gusts to 26 knots (30 mph) as the associated surface low deepened across north-central Illinois. This provided the low-level winds a long fetch over the relatively warmer open waters of Lake Michigan. Additionally, steep lapse rates and lake-induced CAPE between 250 and 280 J/kg, produced lake-effect snow bands that enhanced snow accumulations near the lake. Some wind gusts to 30 to 39 knots (35 to 45 mph) were reported along the Lake Michigan shoreline, resulting in snow drifts of 1 to 3 feet in height. Numerous vehicle spin-outs and accidents were reported across south-central and southeast Wisconsin. At least two people were hospitalized due to serious injuries suffered in vehicle accidents: one in Salem (Kenosha Co.) and the other one in the Town of Lyndon (Sheboygan Co.). Both are considered indirect injuries.
Maximum snow amounts in each county included 13.1 in Germantown (Washington Co.), 12.5 in Sturtevant (Racine Co.), 10.2 in Big Bend (Waukesha Co.), 10 in Elkhart Lake (Sheboygan Co.) and West Allis (Milwaukee Co.), 9.4 in Port Washington (Ozaukee Co.), 9.2 in Reedsburg (Sauk Co.), 8.6 in Horicon (Dodge Co.), 8.5 in Dodgeville (Iowa Co.) and Paddock Lake (Kenosha Co.), 8.4 in Argyle (Lafayette Co.), an estimated 8 in far west-central Green County and far east-central Walworth County, 7.9 in Milton (Rock Co.), an estimated 7.5 in far southwest Dane County, 7 in Watertown (Jefferson Co.) and Ashford (Fond du Lac Co.).
