Milwaukee is waking up to partly cloudy skies and temperatures around 57 degrees Monday, but the clouds will give way to a sunny, comfortable afternoon. Highs should reach about 76 degrees, with light north winds keeping the day pleasantly mild rather than midsummer-hot.

Sunny Monday, Crisp Monday Night

The National Weather Service in Milwaukee/Sullivan expects dry weather through Monday, with north winds of 5 to 10 mph and a few clouds returning late in the day. No watches or warnings are posted for southern Wisconsin or Lake Michigan, according to the National Weather Service.

Monday night will turn noticeably cooler, with partly cloudy skies and a low near 58 degrees. Patchy fog could develop after midnight, especially in low-lying areas, but any fog should fade shortly after sunrise Tuesday.

Warm Tuesday Leads Into Midweek Storm Chances

Tuesday brings mostly sunny skies and a high near 81 degrees, with a southwest breeze of 5 to 10 mph. The first rain and thunderstorm chances arrive after 1 a.m. Tuesday night, when the chance of precipitation reaches about 30%.

Wednesday looks warmer, with a high near 84 degrees and a 40% chance of showers and thunderstorms. Some storms could linger into Wednesday morning before conditions improve by Wednesday afternoon, though forecasters say the chance of severe weather remains low.

Clear Skies Return Before A Wetter Weekend

Thursday and Friday should bring a welcome stretch of sunny, dry weather, with highs near 81 and 76 degrees, respectively. Overnight lows will settle into the low to mid-60s, making for comfortable sleeping weather and relatively easy outdoor plans.

Rain and thunderstorm chances rise again Saturday night and Sunday. Saturday carries a 20% chance of showers or storms during the day, increasing to 40% overnight, while Sunday brings a 50% chance with mostly cloudy skies and a high near 79 degrees.
