Tornado Hits Parts of Waukesha County

***Watch WISN 12 News for the latest on the tornado that hit Waukesha County!***

Severe weather hit parts of Southeast Wisconsin this evening.  The hardest hit areas were in Waukesha County from Eagle to North Prairie east to Muskego where a tornado(possibly significant) touched down.

Here is a timeline of the events that occurred this Monday evening.

  • 8:02 p.m. First Tornado Warning issued for southwest Jefferson County
  • 9:03 p.m.  Tornado Warning issued for south central and southwest Waukesha County
  • 9:16 p.m.  Reports of Tornado hitting Eagle & near North Prairie in Waukesha County(13 minutes of lead time before the tornado hit)
  • 9:48 p.m.(estimated)  Reports of damage from possible tornado in Muskego

We did severe weather coverage on WISN 12 News for much of Monday evening beginning with the first warning at around 8:00 p.m.  I focused on the storm relative velocity which helps to show rotation within the storm.  This is what the first tornado warnings were based on…meaning they were radar indicated.

The map below shows an incredible radar signature showing strong rotation at 8:34 p.m. near Muskego.  This is when a possible tornado hit parts of Muskego.

Many viewers sent in storm photos and reports and we thank you!  If you have VIDEO or PICTURES of the tornado, storm clouds or damage please post it to the U-Local section of   Below is a link.

Please stay tuned to WISN 12 News for more on the aftermath of the tornadoes, and also the latest on the severe weather potential for Tuesday and Wednesday.

  1. You guys had a busy night. Those of us living up in northern Dodge County breathed a sigh of relief as we saw the nasty storms stay far to our south. Unfortunately, some communities down south saw significant damage. Glad no one was seriously injured.

    We had a thundershower roll through here between 9:00-9:30 with some heavy rain accompanied by thunder and lightning, but no wind. The rain just came straight down.

    Hope we will be as lucky later today and tonight

    • Cliff,

      The best news of last night was no serious injuries from the tornado. Looks like the NWS rated it a strong EF-2. We’ll talk more about this on WISN 12 News today. Thanks for the report.


  2. Good job covering the storm last night Jeremy. But what about True Beauty? I only got to see 10 minutes of it before you came on the tv. When I tune in to see True Beauty, I don’t expect to see you.

    • Pete…watch our newscasts today or check Hopefully we can re-air the show. The True Beauty fans were much more understanding of the weather cut-ins than the Bachelorette fans:) Thanks for the note. Jeremy

  3. I am located just off tans dr. and high bluff dr. in Muskego and observed the storm as long as I could. I heard the sirens go off twice, but before it went off for the second time, I heard that distinct rumbling sound. I know it wasn’t thunder and seconds later the siren started going off. I feel confident that I indeed heard that twister.

    • Lucas,

      I’m guessing you heard the tornado near Muskego. Glad you are okay! I was one mile from a nightime tornado in Salina, KS back in 2008…very scary!


  4. What do you think our chances are of having tornadoes today/tonight? Last night wasn’t supposed to be the way it was, do you see anything that raises concern right now for later on?

    • Kevin,

      Highest risk for severe weather is overnight and then again on Wednesday. Biggest threat is damaging winds, but as I stated in the blog yesterday, you can never rule out an isolated tornado when severe weather strikes. SPC has our area in a moderate risk for severe wx late tonight and Wednesday.
