There may be a little rain in the morning, but there will probably be a break in any action that could develop on Sunday. The longer the atmosphere has to prime up, the better the chance of any storm becoming severe. This potential will begin in the afternoon. This is not a guaranteed severe weather outbreak. As it sits right now, the better potential of severe T'storms are further north and west of the area. This could change. Our main threats tomorrow afternoon are damaging winds and hail. Most of our area is under the slight risk of severe thunderstorms. That means IF you see a thunderstorm, there's a slight chance these could become severe. The higher tornado potential, as things sit at the moment, are further to the north and west. They are under the moderate risk of severe thunderstorms. Highs tomorrow will be quite warm with readings topping out in the mid- to upper-70's.
Tomorrow night, the main batch of energy with this system will be working through Wisconsin. With it, more showers and T'storms will be working through the area. These again, could be strong to severe. The main threats would be damaging wind and hail. The better tornado potential would be further to the north. A lot of this activity tapers off later in the night. Overnight lows will be in the low-50's.
Get ready for much cooler temperatures with plenty of wind on Monday. Highs will only top out in the mid-50's before falling into the 40's as the day progresses. We could see a few scattered showers, but it wouldn't be an all-day rain.
Most of the rain chances will work out of here on Monday night. Get ready for another frost potential, but this is not uncommon at this time of year.
Tuesday looks quiet and dry. Highs will top out around 50 for our lakefront communities and Milwaukee temperatures, and mid-50's for Waukesha's temperature and inland areas.
There's another chance of rain on Wednesday, but there won't be any big warm-ups or cool-downs for this upcoming week.
