The chilly air sticks around for the first half of tonight but then clouds roll in ahead of a warm front by dawn and under the clouds there may be a little light snow. The snow could linger through rush hour in the monrning until about 10 am. Any accumulation would be light in the form of a dusting or so in southeast Wisconsin. The temperatures jump back in a big way to near 40 degrees for Friday and Saturday on very windy southwest breezes, and there could be a little light snow or a rain snow mix again on Saturday afternoon. A big Arctic air mass slams into Southeast Wisconsin for Saturday night, Sunday and the beginning of next week. That's when high temperatures will stay stuck in the teens and even single digits, and we could see our first below zero reading on Tuesday morning!
