The southeast Wisconsin, Waukesha and Milwaukee forecast for the rest of the night will consist of a few lake effect clouds pushing through. With a few of those clouds, a few flurries may fall, but it's nothing that will cause you any problems the rest of the night. Overnight lows will bottom out in the mid-teens for our lakefront communities and Milwaukee temperatures and around 10 for our inland areas and Waukesha temperature. Our temperatures will actually rise as the late night goes on.
A few areas to the west might start off a little bit on the cooler side. As this system moves closer, it will start to touch off a little drizzle, light rain and possibly a little freezing drizzle. This does NOT look to be a major icing event. Overnight lows will bottom out in the low-30's but actually might be rising as the night wears on. None of the precipitation looks heavy at all.
Tuesday will be partly cloudy to mostly sunny and seasonable. Highs will top out in the upper-20's.
