Sunday was hot. It’s also the second day anniversary of the hottest temperature ever recorded in Eau Claire’s history. 111 degrees set on July 13th and 14th in 1936.
It was also humid, and mother nature is primed to kick up some thunderstorms overnight that could start your work week, wet.
Meanwhile, a Mesoscale Convective Vortex, which is a small scale low pressure system that produces a circular wind pattern and often times heavy rainfall bands, is moving towards the Chippewa Valley. the timing for this storm will hit closer to sunset through the early morning hours.
The severe weather threat is usually lower inside these systems. The biggest concern with this system is flash flooding. As of now, there is no watch in effect for Western Wisconsin, but check back frequently for updates.
This storm may produce 3-hour rainfall amounts of 1 to 2 inches, with isolated higher amounts. This exceeds the threshold needed to issue a flash flood warning, so keep an eye out tonight and don’t drive through flood waters!
We repeat the heat and humidity again Monday with more storms possible late Monday evening. We just keep rolling with the same heat, humidity, and thunderstorm threats through the week.
