Early Evening Update....storms are moving south

Scattered showers and storms will move out of the southern part of our area between 7 pm and 8 pm.  Storms over Walworth, Racine, and Kenosha counties are showing signs of wakening.

A possible tornado was reported in the  Deerfield community just west of Jefferson county shortly before 4 pm.  A few buildings were damaged along with several trees.

5 PM Update:  Scattered showers and storms south of I-94 remain very strong this evening.  We do expect a gradual decrease in intensity through 7 pm.  The storms are expected to move out of the area between 7 pm and 8 pm.

3 PM Update:

Scattered showers and storms have erupted along a boundary across SE WI this afternoon.  Surface temperatures in the 80s combined with plenty of humidity have fueled the storms.

Storms that do fire could contain small hail and brief gusty winds.  Locally heavy rainfall will be the greatest threat with the storms.  Rain and storms will likely move southwest and out of the area after 10 pm.

NOON Update - The cold front will be the trigger for showers and storms once that atmosphere gets primed up.  The timing looks to be after lunchtime through sunset, with the 2-7pm time being the best chances.  The main threats will be hail and strong winds.  With the higher amounts of moisture present, heavy downpours and ponding of the roads will be possible. The SPC's marginal risk has shifted a bit; it still includes a chunk of SE Wisconsin and parts of the metro.


An upper-level trough and cold front will be the main weather maker today giving way to developing scattered showers and thunderstorms by this afternoon. Ahead of this front, temperatures will drive well into the 80s today, add in higher dew points, and this will give the storms some better dynamics to work with. So, some of these storms that kick up this afternoon could be stronger, especially southwest of Milwaukee where there could be a few storms producing strong winds and hail. Highs will make a run at 90.

This might be our only chance of rain for quite a while. The next five days after today, there remains just slight chances of rain until the middle of the week. That bodes well if you want a nice weekend, not if you want a good soaking for your lawn. Behind the front, high pressure moves in and this gives us the dry weekend. Highs will stay in the low 80s with plenty of sunshine!
