The southeast Wisconsin, Waukesha and Milwaukee forecast for the rest of your Saturday night will have rain around the area. It becomes steadier as the night wears on. Current indications have rain totals over a half inch. Major flooding doesn't look to be an issue, but the snowpack will take a hit. It is March. Lows will be above freezing in the mid-30's.
Sunday looks like we'll have some areas of rain hanging around. Highs will top out in the low-40's. This will not be the main slug of rain.
Sunday night, more rain will be around the area. Now here's the kicker. The further you live to the northwest, the better your chance of this changing over to snow. The computer models have the bulk of this barely missing us, but it's going to be a close call. Because of this close call, ***A Winter Storm Watch*** has been issued for Fond du Lac County on Sunday evening, rolling through midday Monday. They could see 1-2" on Sunday night. If this whole storm system shifts further southeast, we may start seeing a lot more snow out of this.
Monday, areas to the northwest probably will start off with some accumulating snow. If this system shifts southeast, we'd all see more snow. An additional 1" is possible to the northwest, while the rest of us should see less than that with a few flurries or snow showers. Current computer models have The far northwest counties with a total of 1-3". It's all about the track.
Tuesday, we could see a rain or snow shower, but it shouldn't be a big deal.
Most of the rest of the week, starting Wednesday looks fairly quiet with temps popping above freezing every day. It still won't be that mild though for this time of year.
