Thank you for stopping by the Weather Watch 12 Blog! The heat and humidity continued to blast the area on Thursday, as the heat index climbed to 101 degrees in Watertown! Only a light lake breeze kept the temperature in the 80s in Milwaukee. The official high on Thursday was 88 at Mitchell Field.
By Friday, winds will shift around to the south, and the lake breeze will affect fewer locations. In Milwaukee, highs should soar into the lower 90s with heat indices in the mid to upper 90s. As the heat and humidity continues, a cold front will be nearing the region. As the front slams the heat and moisture, the potential will exist for severe weather.
If you have outdoor plans on Friday it appears that most of the day should be dry. The later we get into the afternoon and especially the evening, the higher the rain chance. As of Thursday evening, our in-house high resolution computer model was placing a line of strong storms across southern Wisconsin around 10-11 p.m. Below is a snapshot of the storms at 10 p.m. Friday. Keep in mind this is from just ONE computer model.
The Storm Prediction Center also has our area highlighted for the potential for severe weather. This puts a bullseye over areas to our west with a 30% chance. What does this mean? It means there is a 30% chance of severe weather within 25 miles of a point. The map below keeps southeast Wisconsin in the 5-15% area.
I think when the adjusted severe weather outlook is issued by the Storm Prediction Center on Friday morning, southeast Wisconsin will be in a slightly higher risk area. The biggest threat from the storms will be damaging winds. We’ll have to watch this closely, because there will be plenty of fuel for these storms to work with.
Keep in mind, day or night 24 hours a day we will keep you updated on WISN 12 if severe weather strikes. I’m already planning on a ‘long’ evening/night in the weather office for Friday.
