Very light snow or a few flurries are possible overnight before the snow really flies later on Tuesday morning.Overnight low temperatures will stay in the upper-twenties with clouds and winds off the lake. Most of the accumulating snow won't start moving into southeastern Wisconsin until after 8am and it will become more widespread throughout the late morning hours on Tuesday. The worst period of snow looks to be midday with 1-2" of snow expected across much of the area. Higher amounts are possible in the southwest with lighter amounts expected in the northeast as this storm is taking a more southern route. Snow tapers off late Tuesday night with an additional inch possible, keeping storm totals mainly between 4-7" south of Milwaukee and about 2-4" in Milwaukee and Waukesha.
