Will see temps gradually warm up through the weekend with mid to upper 40s by Sunday. However, warmth will be accompanied by rain chances. Then a strong cold front is expected to push through later Sunday and will see temps quick drop and a potential for accumulating snow overnight into Monday.
Rain on Sunday will transition to snow Sunday evening as colder air quickly moves into southern WI. Current accumulation potential has 50 to 70% chances for at least 2 inches of snow north of Interstate 94. Some questions still remain about exactly where/when the storm will intensify, which may influence snow totals.
