Still Cooler by the Lake, Monday
The southeast Wisconsin, Waukesha and Milwaukee forecast for the rest of your Saturday night will be fairly quiet for the night besides a slight chance of a sprinkle. Overnight lows will be around 40.
The daytime hours on Monday will be quiet. Again, we're not going to get very warm thanks to the persistent breeze off of Lake Michigan. Get away from the Lake to warm up. Skies will be partly to mostly cloudy with highs will top out in the low-50's by Lake Michigan but low-60's well inland.
Our best chances of rain will be on Monday night. That will be a cool front moving through with lows in the mid- to upper-40's.
Tuesday, we could have a lingering morning shower, but the day won't be a wash. Highs will top out in the upper-50's for our lakefront communities and Milwaukee temperatures, but mid-60's for Waukesha's temperatures and areas inland.
Most of the rest of the week after Tuesday should be dry and cooler by the Lake. That means 50's lakeside and around 60 inland.
Opening Day looks dry with highs in the mid-50's. That means the roof will be closed, but it still will be nice out.
