Rain, Rain, On The Way

***Watch WISN 12 News at 5, 6, & 10 p.m. for live radar updates!***

************9:30 PM Update*******************

Rain/Storms slow to arrive. Storms not likely before 2 or 3 AM. A rainy Thursday morning commute tomorrow. Some pockets of heavy rain possible, but most areas staying under .50″ of rain. Check out the latest radar below and stay up to date with Interactive Radar on wisn.com.


Thank you for stopping by the Weather Watch 12 Blog!  Seven of the past eight days have been dry in Milwakee and across much of southeast Wisconsin, but that is about to change.  Several rain chances are in the forecast and the first chance heads our way tonight and early Thursday.

For today not much to worry about weatherwise, just increasing clouds and temperatures in the upper 60s.  By this evening, low pressure will move across the upper Midwest, and begin to push rain and thunderstorms in our direction.

Below is a surface forecast map for 1 a.m. Thursday.  Low pressure and a warm front will hang near the Wisconsin and Illinois border.  This will help to lift the air resulting in showers and t-storms.  Just click on the image to enlarge.

While showers and storms are likely across southeast Wisconsin, severe weather is not.  In order for severe weather to occur, 3 ingredients are needed – moisture, lift, and instability.  The ingredient lacking in our area will be instability and higher dew points.

The threat for severe weather thru 7 a.m. Thursday will reside from the Twin Cities to La Crosse and then south to Springfield, MO.  Below is the severe weather outlook from the Storm Prediction Center.

Rain totals will vary greatly since heavier downpours will be contained in thunderstorms.  Outside of the thunderstorms, light to moderate rain will occur.  Rain totals will likely be in the neighborhood of 0.25″ to 0.75″ by the time the rain ends early Thursday.  If thunderstorms do occur, some spots may see 1.00″ or more of rain.

You can track the rain day or night right down to your backyard with our interactive radar.  If you’ve never tried it just click below.  The ability to zoom in and out, and also move the radar is a great feature!


Once the rain exits, the wind will increase, and temps will stay in the mid-60s.  At least we may end Thursday with a little sunshine.  Slightly milder weather returns for Friday.

Finally, 3 tropical systems are in the Atlantic Basin right now…Igor, Julia, and Karl.  Julia and Igor are major hurricanes, while Karl is a tropical storm near the Yucatan Peninsula.  Below is a look at all 3 systems on the visible satellite…pretty cool!

If you have any questions or thoughts, please post them to the comments section of the blog.  Have a great day!

  1. Enjoy your rain chances. We are soaked to your south. We have had 3-6 inches + in the last 7 days.

    Long range GFS looking different. Start counting days. LOL

  2. Wow! It happened again. We didn’t get ANY rain overnight when forecasts were generally calling for between 0.5″ to 1.25″.




    • Michael,

      Not sure where you saw a forecast that high, not here. Anyways, most of the appreciable rain stayed in south of Milwaukee. Kenosha had 0.43″ of rain and parts of Walworth County close to one inch. Milwaukee offcially a big zero at Mitchell. Thanks for adding your thoughts.
