What a crazy morning in Milwaukee. One cluster of thunderstorms dumped very heavy rain over downtown creating flash flooding on the east side. Riverside High School had significant flooding and some cars were stranded in the high water.
Check out the link for Marianne Lyles story about the flooding:
Take a look at the radar estimate of rainfall in Milwaukee.
The rainfall was very concentrated in the downtown area. Most parts of SE Wisconsin picked up less than 1/4″ of rain. 2″ of rain fell in about one hour.
I am becoming concerned about Tuesday’s severe weather setup for our area. A strong low pressure center will slowly move closer to our area pushing a warm front into Southeast Wisconsin. The big question is how much sunshine we will get tomorrow. If we get a lot of sun, I am worried for a pretty big outbreak of severe weather. This would include the possibility of tornadoes. Here is the risk from the Storm Prediction Center.
I would not be surprised to see the risk raised to moderate for Tuesday. Here is the RPM computer model for 4pm tomorrow.
Note the individual cells moving through the area. Because of the proximity of the low pressure center, there will be plenty of shear available to get these storms spinning. I am hoping the storms that are currently across Nebraska, Kansas, and Iowa produce enough cloudiness that we stay cloudy tomorrow. If that does not happen and we are sunny, the atmosphere will become very unstable. Please stay tuned throughout the day tomorrow. Stay safe.
