The southeast Wisconsin, Waukesha and Milwaukee forecast for the rest of your Saturday night will be quiet with clouds on the increase. Overnight lows will be in upper-teens for our lakefront communities and Milwaukee temperatures, and mid-teens for our inland areas and Waukesha temperatures.
Sunday slowly goes downhill as the day wears on. We'll see some light snow and sleet developing in the afternoon. This is not going to be a big snow-maker as totals for many of us will only see a trace to 1 inch by the end of the day. We will start to mix in freezing rain later in the afternoon from the south. Because of this mix of snow, sleet and freezing rain, the National Weather Service starts a ***Winter Weather Advisory at 2PM Sunday until late Sunday night for the whole area.***
Sunday night, any snow and sleet will change over to a period of freezing rain with the temperatures hovering right around the freezing mark to start the night. Ice accumulation should be between 0.10 to 0.20 inches with any snow changing over to this to the north. This may cause a glaze on any untreated roads or anything else sitting outside. The key is, the temperature will actually rise as the night goes on. That means freezing rain will just change over to rain overnight.
Monday will be mild and a little foggy. We could see a few scattered, light showers. Highs will top out in the low-40's.
Tuesday, rain will develop and it's going to be warm out. Highs will top out in the low-50's the way things look right now.
A strong cold front rolls through on Tuesday night.
Wednesday through the next weekend will be cold again and windy to end the week.
