A heat advisory was in effect for much of the day, but we never reached heat advisory criteria here. So what happened? We never even made it to 90 and our heat index stayed under 95. The heat advisory was cancelled for most of our counties, but continues in Fond du Lac, Jefferson, and Dodge counties until 9pm.
The reason for missing the heat had to do with thunderstorms that rumbled north to south across Lake Michigan this morning and early afternoon. That brought us some cloud cover, but also kept the wind southeast until later in the day. That kept our temperatures a little cooler and dewpoints stayed in the low to mid 60s. Tonight the dew points are much higher hovering around 70 degrees. Our lows tonight will be warm, staying in the 70s and it will be sticky.
The holiday weekend forecast is a good one. All three days look to have plenty of sunshine. It will be hot and sticky on Saturday with highs in the upper 80s. A cold front will move through in the morning, but chances of storms will be very minimal. Cooler air will then arrive on Sunday and Monday. Sunday looks great with highs in the upper 70s near the lake and lower humidity. Independence Day will be sunny and comfortable with a high of 80. The weather will be great for all the fireworks and parade celebrations. For a list of all the parade times and fireworks in your area click here:
I wanted to talk a little more about the crazy storms that hit on Thursday evening in Racine and Kenosha counties. Even though little to no rain fell, the storms brought 60-80 mile per hour winds knocking down hundreds of trees and taking out power to over 20,000 customers. In all my years here, I have never seen a storm over Lake Michigan create a downdraft that moved east. It was a very unusual storm. I wanted to show you what the storm looked like in 3 dimensions. It was a very powerful storm.
The storm was over 50,000 feet tall and had a hail shaft that rose to 30,000 feet. That is really incredible for around here. A big thank you to the National Weather Service for providing the image above. There were some amazing pictures of huge 50-100 year old trees knocked to the ground from the straight-line wind damage. The first one is from Vick Frederick on 13th Street in Racine.
Vick was rather fortunate this did not hit the house directly. The next image was sent to my Facebook page from Amada Aude of Racine.
The clean up will take a long time. I have talked to quite a few long-time residents from Racine and Kenosha and many say this is the worst storm that they have ever seen. Always remember to stay away from power lines after a storm like this. Treat all of them as if they were live even if they are not sparking.
Have a safe and happy 4th of July weekend from Weather Watch 12.
