First Alert Day Tonight & Monday; Arctic Blast Mid-Week

MADISON, Wis. (WMTV) - Another clipper system is moving through Wisconsin tonight. Latest model trends have pushed the center of the system closer to the Capital Region. As a result, snowfall amounts have increased & several counties have been added to a Winter Weather Advisory. A First Alert Day has been declared for the remainder of Saturday into early Sunday. The heaviest snowfall will be focused over NE Iowa & SW Wisconsin. 1-3″ of snowfall is expected for much of the region tonight - with 2-4″ totals SW of Madison. A few locally higher amounts are possible. The National Weather Service has included much of south-central Wisconsin in a Winter Weather Advisory - including Dane County & the city of Madison. The advisory expires at 3 a.m. Sunday. Amounts fall to around 1-2″ near Madison and drop off farther North & East. Sunshine is expected again by Sunday afternoon. Highs will only climb into the teens.

Sunday Night - Monday Morning

The final clipper system moves by late tomorrow night into early Monday morning. Widespread snow showers begin after 10 p.m. Sunday and continue until just before sunrise. Most areas could see around 1-3″ with higher amounts near and NE of Madison. Highs on Monday will climb into the upper 20s. SW winds will switch out of the NW by the afternoon - beginning a much colder trend towards Mid-Week.

Arctic high-pressure moves back into the Great Lakes Region - bringing low temperatures below-zero Tuesday and Wednesday with highs in the single-digits both days. Dangerous wind chills are possible during this time frame - First Alert Days will be considered should trends hold.
