Weekend Weather: Excessive Heat and Strong Thunderstorms
Before you head out the door for the weekend, here is the latest weather information!
Heat will be the main story. Excessive Heat Warnings are in effect for a large section of Wisconsin. Temps of 90-100F, plus high humidity will drive the heat index into the 100-110F both today and Saturday. Thunderstorm activity increases Saturday night and Sunday as a cold front arrives. Strong to severe thunderstorms are possible.
Saturday, Jun 30 2018- Temperatures stay warm overnight into Saturday, becoming excessively hot during the day. Looks like a repeat of today. Breezy at times. T-storms are possible across Upper Michigan and the far north during the morning which could be strong. High temps will reach the 90's with humidity-driven heat indices exceeding 100F once again.
It's possible a thunderstorm complex will form overnight into Sunday morning. Because of this strong thunderstorm chances were extended into northeast Wisconsin but this prediction is less certain. I considered using severe wording more aggressively but decided against it. We will be watching closely.
Excessive is a relative term and hype is not our thing, but Friday and Saturday will be about as toasty as it gets for Wisconsin.
