Slight Risk of Severe T-Storms

***Watch WISN 12 News at 5:30 & 10pm for the latest radar updates!***

The first taste of severe weather is possible across parts of Southeast Wisconsin this evening.  A weak cold front dropping through the region will spark showers and thunderstorms.  A few of these storms may contain hail or strong winds. 

A slight risk of severe weather exists from generally I-94 and points south and southeast.  If severe weather develops, it would most likely occur between 6 p.m. and Midnight.  You can track the thunderstorms on our interactive radar right down to your backyard.

Below is the latest convective outlook from the Storm Prediction Center.  Notice that just a small part of far Southeast Wisconsin is included in the slight risk area.  Just click on the map to enlarge.

If you are wondering, in order for a thunderstorm to be considered severe it must contain at least one of the following;  hail of at least 1.0″ in diameter, winds of 58mph or greater, or a tornado.  The severe weather can be radar indicated or reported by a spotter for a warning to be issued.

Looking at the latest data, it continues to support a chance of showers and thunderstorms this evening.  Notice on the forecast map below from the 18Z NAM(North American Model) that most of the activity would occur in far Southeast Wisconsin and northern Illinois.

If thunderstorms move over your backyard this evening or in the coming days…please post your storm reports and rain totals to the comments section of the blog.  You can also drop off storm reports to our Facebook page…WeatherWatch 12

Also, if you take pictures during or after a storm, we would love to see them!  Just post them to the U-Local section of and also feel free to email them to me at

Have a great night and watch WISN 12 News at 5:30 and 10pm for the latest radar trends and the Opening Day forecast!
