MADISON, Wis. (WMTV) - Our winter storm brought accumulation of snow across much of southern Wisconsin overnight. Travel conditions will be hazardous in some locations, especially north of Madison. Secondary roads will be of particular concern. Today is a First Alert Weather Day due to these travel concerns.

An update to the Wisconsin Department of Transportation’s 511 map around 4:30 a.m. back that trend. It shows highways in the Madison area and directly to the west of the city (purple) have slippery stretches. As soon as drivers head north, though, they run into snow-covered roads. Yet, Janesville and Beloit are reporting good winter driving.

Light snow and flurries will continue at times today and into the evening, but very little additional accumulation is expected. Some locations will experience a little drizzle or mist mixing in. As the low pushes off to the east of here, drier air will fill in overnight. Wind will pick up as well with gusts of up to 25 mph by tomorrow morning.
