Snow is the one the way for tonight, but not much. It looks like we'll pick up an inch or two. Just a little more is possible well north of Milwaukee and Waukesha. For example, areas from Port Washington north to Sheboygan and West Bend north to Fond du Lac, could pick up 3 inches.
Start time on the snow will be 4-7 p.m. this evening. The snow will end between 12 a.m. and 3 a.m. Tuesday morning, but will be followed by periods of freezing drizzle. That could lead to slippery spots on roads and sidewalks for Tuesday morning rush hour. The temperature is expected to get above freezing by about 9 a.m. or so on Tuesday ending the threat for icing.
Another threat for snow is exists for Thursday Night and Friday. So far, though, there's no reason to believe this will be a big deal.
I'll keep an eye on it.
