***Watch WISN 12 News for the latest weather information!***
Thank you for stopping by the Weather Watch 12 blog. After Wednesday’s heavy downpours in Milwaukee, and the brief tornado near Cambria, the quiet weather on Thursday was welcomed.
The Cambria tornado was produced by an isolated low-topped supercell. It spun up quickly and without warning. Here is video of the tornado just south of Cambria!
Here is the very latest on the tornado from the NWS survey that was conducted on Thursday.
The tornado was rated EF-1, with winds estimated at 90-95 mph.
Below is a map for the tornado’s path. The path length was 4 miles, and the tornado was on the ground from 6:27-6:41 p.m. Below is a map of the path, and also a couple of damage highlights. Just click on any of the images to enlarge.
During our tornado coverage last evening from 6:30-7:30p on WISN 12 we showed the velocity of the storm numerous times. This helps us guage the direction of the winds within the storm. When a tornado occurs a tight ‘couplet’ will often appear on the radar. When green(toward the radar location) and red(away from the radar location) are right next to each other in velocity mode, this indicates rotation. Often when this rotation appears a tornado is either on the ground or possibly about to develop.
Below is the velocity at 6:32 p.m. when the tornado was on the ground. This map is from the NWS NEXRAD radar.
If you have ever heard us say “Radar indicated tornado”, that means something like the map above is showing rotation, but no spotters have reported a tornado.
The good news is we shouldn’t have to worry about thunderstorms or severe weather for a few days. Cooler and less humid weather will return to the region on Friday. below is a surface map from 4 p.m. Thursday. When looking at this map check out the dew points in the 50s in central Wisconsin. The dew point(green number) in Wausau was 55 degrees, while in Milwaukee it was still a sticky 68! The lower dew points will try to work into our area in the next 24 hours.
Enjoy the quiet and less humid weather, and make sure to stop back for an all new weather blog again on Friday!
Have a great day!
