Wet and windy weather expected later Sunday afternoon through Monday

 

Update as of 7:30 am, Sunday, October 24th

We're still on track for some unsettled changes, coming as soon as after lunch as moisture begins to overspread the area from the south and west.  Winds will pick up and stay gusty through much of Monday.  The heaviest of rain will fall from Sunday late in the day through Monday morning.  1-2"+ amounts are possible.  Again we could see wave heights more than 10 feet, especially on Monday.  Boaters, be advised and stay off the water, starting Sunday afternoon really.  Wind gusts from the northeast will howl more than 40 mph at times as well. Improvements come on Tuesday and Wednesday.

After a beautiful start to the weekend, clouds will be on the increase to start the day on Sunday ahead of a developing area of low pressure. This system will track across Illinois late Sunday into Monday, bringing rain and windy conditions to southeast Wisconsin. Dry weather is expected through Sunday morning, but showers will move in from the south mid to late afternoon.

Rain will become widespread and steady Sunday night into Monday morning.

Showers will taper off for most Monday afternoon, but showers may linger a bit longer near the lakeshore. The heaviest and steadiest rain is expected near the WI/IL border, where 1-1.50" of rain looks likely. Around .75-1.25" is expected along I94 with a sharp cut off in Sheboygan and Fond du Lac counties. Up to .50" is possible far north, but some spots could end up with much less.

As this system gains strength, ENE winds will increase Sunday afternoon, gusting 20-30 mph. The wind will get even stronger Sunday evening through Monday with gusts of 35-45 mph expected.

The most frequent 40+ mph gusts are expected near the lakeshore, where a Wind Advisory has been issued for Monday.

The strong ENE winds will generate 7-10 ft waves on Monday, which will likely lead to lakeshore erosion and minor lakeshore flooding. A Lakeshore Flood Advisory has also been issued for Milwaukee, Racine, Kenosha, and Ozaukee counties from 12 am Monday - 7 pm Monday.
