Nothing like coming back from vacation to severe weather and a crazy temperature drop. Honestly, I don’t think I would want it any other way. Wisconsin in June brings a little bit of everything. After 3 days in a row with record-setting or tying high temperatures of 94, 97, and 93, the temperatures this afternoon hovered right around 50 degrees.
It was my two oldest daughters last day of school today and we all shivered through a picnic lunch. I felt bad for the kids whose parents must not have seen the forecast and their kids were dressed in shorts. The picture below is of my daughter Claire. Notice that she is dressed appropriately. I have made the mistake too many times of not getting my kids in warm enough clothes. This does not go over well when your dad is a meteorologist.
Yesterday was quite a day around the weather center. I was too busy to post a blog so I will try to make up for that today. The cold front meant serious business late yesterday. It was a pretty good setup for severe thunderstorms with all of our low-level moisture and hot temperatures. One main ingredient that was missing was shear. That is why we only had one tornado southwest of Madison. Here is the write-up from the NWS:
The weak tornado, rated EF1, touched down in central Dane county, as verified in a National Weather Service damage survey crew on Thursday, June 9th. Assistance with the survey was provided by members of the MidWest Severe Storm Tracking/Response Center. The tornado spun up about 2.5 miles west-southwest of Verona at about 741 pm CDT and continued for about 21 minutes. It dissipated about 802 pm CDt about 3 miles northeast of McFarland.
Damage consisted primarily of uprooted trees and broken tree branches which fell on power-lines. In Verona, damaged trees or tree branches crushed a garage, and damaged at least one home and a vehicle. Scattered power-outages were noted. Some minor roof shingle damage was seen. The tornado had a maximum width of 100 yards. The path length was about 17.6 miles. This tornado was rated at the bottom of the EF1 category with wind speeds of about 86 to 90 mph. Damage along the path was sporadic.
The bigger issue was the cold pool of air that surged in behind the main line of storms and pushed a bow echo across SE Wisconsin. Severe thunderstorm warnings were issued for almost every county. There was a real possibility of hurricane force winds with the bow echo. The radar was showing 70-90 mph winds just aloft the surface as the storms emerged from Dane and Rock counties. We were fortunate that the strongest winds never mixed to the surface. Even without, the strongest winds, there were still plenty of damage reports from Jefferson, Walworth, Racine, and Kenosha counties. There was also sporadic damage around other parts of the area. Here are a few of the images sent to Weather Watch 12.

Browns Lake had strong winds that damaged a boat and pier. Thanks to Greg for the photo.
The above picture is my favorite. It is from Matt in Milwaukee. He was flying back to Milwaukee from Las Vegas and took the picture of the cumulonimbus clouds as it was just beginning to break the cap.
Our weather will stay rather chilly for the next few days and we have more rain on the way. That will happen again late tonight. Here is the RPM forecast for 6am Friday morning.
Rainfall totals will likely range from .50″ to 1″ across the area. Here is the RPM forecast for accumulated rainfall.
Coming up in tomorrow’s blog, I will focus in on the weekend forecast and talk about the heat burst that parts of the area had on Wednesday. Quite a rare phenomena in our area.
