Increasing temps and humidity through the Memorial Day weekend
It's been a rather soggy last 48 hours with 1-2" of rain falling across most of southeast Wisconsin. This has basically eliminated our precipitation deficit not only for the month of May, but for 2022 as well.
The slow moving low pressure system responsible for this wet weather is finally pushing to the east with drier weather moving in for most of the extended Memorial Day weekend. The exception will be Saturday afternoon through early evening with a few isolated showers and a rumble of thunder are possible.
That being said, the better chance for rain Saturday will be across the northern half of the state.
Onshore wind will keep temperatures near normal in the low to mid 70s on Saturday, but winds turn to the south and southwest for Sunday and Monday, boosting temps back into the 80s. Some spots away from the lake may even make a run at 90° on Memorial Day.
While wind will be light on Saturday, you'll definitely notice the wind on Sunday and Monday with gusts over 30 mph possible at times. This is what will help pump in the warmer, and also more humid air.
Dew points return humid levels on Sunday and stay there through Tuesday.
A cold front will track through sometime late Tuesday into Wednesday, which will get rid of the warmth and humidity and bring us the next best chance for showers and storms.
