High Winds Strike Racine/Kenosha Counties…Heat Follows

***Watch WISN 12 News for more on the Heat Advisory!***

Thank you for stopping by the Weather Watch 12 blog!  A severe thunderstorm over Lake Michigan sent damaging outflow winds crashing into lakeshore areas of Racine and Kenosha counties Thursday evening.

Here is a list of some of the storm reports that were received in our weather center.

  • Racine Airport  66mph, several trees/branches down in the area
  • Kenosha Airport  58mph, downed trees
  • Large trees uprooted in Kenosha along the lakeshore
  • Shingles blown off homes 1 mile north of Racine Airport

Most of the damaging wind gusts were reported between 7:48pm and 8:10pm.  Below is the radar image at 7:50pm.  Notice that the thunderstorm cell stayed OVER the lake, but the damaging winds rushed out from the storm.  With no buildings, homes, or trees over the lake the winds had nothing to slow them down, and slammed into lakeshore areas creating winds of 60 to 70 mph.

Severe Storm Thursday, June 30

The result of the strong winds were numerous downed trees, power outages, and lots of cleaning up to do.  Our viewers again were awesome sending in lots of pictures.  This picture was one of the first that I received from Karen Aber of Racine.  This tree blocked a side street as people looked on.

Racine Trees Down June 30

Winds didn’t reach severe levels in Milwaukee, but gusts close to 50mph knocked this tree over at 13th avenue.  The picture was posted by a mobile user on the U-Local section of the WISN.com

One last picture from Nikey Mattson of Caledonia.  Here the winds toppled a tree and took out another gazebo.

As the clean-up gets underway on Friday, so will some extreme heat.  Highs will jump into the 90s, but the dew point, a measure of moisture will surge into the 70s.  The combination of heat and humidity will result in heat indices over 100 degrees in many locations during peak heating.  To keep tabs on the heat index at your house, feel free to use the NWS chart below.

If you are working or playing outside on Friday, make sure to take frequent breaks and drink plenty of water!  Stay hydrated!

For the latest on the heat and any storm over the holiday weekend, watch WISN 12 News.

Have a great day and stay cool!

  1. Hi, Jeremy!

    I think we had an experience here in Reeseville {Dodge County} this a.m. that I never remember having before — we had close to an hour and a half of thunder — about every 30 to 45 seconds — with absolutely no rainfall — and very little if any wind — or any other storm related “action.” Really strange — at least to me! The clouds overhead were a really dark “stormy” blue — but what was strange about them was that it appeared to me that they did not move — just sort of hovered above.

    I heard from someone whose son called from Juneau and reported rain so heavy that people had to pull over to the side of the raod because they couldn’t see — and that winds were so strong that a lot of crops in the fields are now laying down instead of standing up.

    Right now I would call it “hazy sunshine” and the temp in the shad — north side of our house — is 86 degrees.

    Will try to keep tabs on temp and see how high it goes today.


  2. I never thought when I posted the ECMWF graphic over a week ago and said it suggested near 100 degree temperatures, it could have possibly verified. Today La Crosse is forecasted (by their NWS) to get to 103. Incredible.

  3. To the best of my estimation, the event looks like one heckava macroburst..yes macro due to the size of the area affected. In looking at some of the radar images and time lapse, it looks like that storm had a wicked core of over 70dbz. That is VERY impressive. For whatever reason, it quickly collapsed and created the very strong outflow. With minimum friction over water, most of the energy was able to conserve packing a punch near the shore. I looked at the skew-T from GLB at 0z, and showed quite a mid level cap. I wonder if this storm ran into the cap and completely lost its cookies…interesting event none the less…

    • Is the following of any use to you for understanding what was going on shortly before and after?

      My location is approx 3 ½ miles inland. Just prior to the wind gust reaching me, my surface winds were brisk, steady, and from the south. Storm like clouds overhead were moving from SW to NE. The storm producing the wind gust was out over the lake and moving in a general S to SW direction. Just passing this along as possibly useful or interesting.
