One Mild Day, then a Little Snow
The southeast Wisconsin, Waukesha and Milwaukee forecast for the rest of the night will see those clouds on the increase. Those clouds could bring us a little patchy freezing drizzle overnight. Lows will bottom out in the mid-20's.
Monday looks to be the milder days of the workweek until things become colder after Tuesday. Highs will top out in the mid- to upper-30's. There's a chance of a little drizzle or sprinkles, but most of the day should be quiet.
A mix of rain or snow could start to develop on Monday night but little if anything would accumulate by Tuesday morning. Lows will bottom out in the mid-20's. You'll also notice those winds picking up.
Tuesday looks like a pretty good shot at a little accumulating snow.. As of right now, it looks like by the end of Tuesday we could see 1-2". Most of this should fall through the morning hours, then taper off as the afternoon wears on. This could change if the storm system gets stronger or takes a different track. Another thing you'll notice is the wind. The gusty, northerly winds will also usher in colder air. We'll start off the day in the upper-20's, but temps will fall to around 20 by the end of Tuesday.
Tuesday night will be windy and cold, but the snow should be gone by then. Lows will bottom out in the single digits.
Most of Wednesday and Thursday should be cold and quiet, but snow could move back into the area on Friday. After that, we could hit 40 again by next Sunday.
