The southeast Wisconsin, Waukesha and Milwaukee forecast for the rest of your Sunday night has that secondary front rolling through, and the temperatures will be falling. As the front moves through, you could see a stray rain or snow shower, but otherwise it will just be blustery and colder with overnight lows in the low-20's.
Opening Day looks to cold and blustery, but looks dry with highs in the mid-30's. Skies will range from mostly sunny to partly cloudy.
The cold and blustery conditions continue on Monday night with overnight lows only around 20. That's way below average for this time of year.
Tuesday will still be on the cool side, but we'll keep it dry. Highs will top out around 40. Not too good for this time of year.
We'll moderate things into the low- to mid-40's for Wednesday with mostly sunny skies, to near 50 on Thursday. Our next chance of a little rain rolls in this upcoming weekend. Most of this upcoming week will have temperatures below average with the coldest being tomorrow.
