A severe thunderstorm watch has been issued for parts of Michigan and Wisconsin until 11 PM EDT

WATCH POSSIBLE: Storms are beginning to develop across far northern WI and the UP of Michigan. A watch is possible, though there's a cap currently in place that may inhibit severe development. #wiwx

Highs today will be sitting around 80º statewide with mostly sunny skies across much of the state. We're seeing some clouds across SE Wisconsin, but I suspect that you'll see some partly sunny skies over the course of the day today.

This is the devastating damage left behind in Menasha after a large tornado swept through the Fox Valley earlier this afternoon. While the National Weather Service will officially rate this tornado in the coming days, the extent of the damage suggests it was a significant tornado

[Wisconsin Wisconsin Authority @wiwxauthority]

Good morning! We will kick off the week with "air you can wear"!🥵 Highs statewide will be in the mid-upper 90s with heat index values making it feel much warmer than that.

- Stay in air conditioning as much as you can
- Drink plenty of water
- Avoid strenuous outdoor activities

and into the afternoon, leading to intermittent sun & clouds. Again, can't rule out a stray hit-or-miss shower but we will otherwise be dry. Have a great day! #wiwx #wisconsinweather #wisconsinweatherauthority

[Wisconsin Wisconsin Authority @wiwxauthority]

Good morning (and apologies for the delayed forecast)!

Today will, for the most part, be dry, but I cannot rule out a stray hit-or-miss shower/thunderstorm. Unfortunately we're at that time of year where diurnal heating (or simply put, the cycle of Earth's surface warming...

and cooling thanks to sunlight/radiation from the sun) can cause a pop-up shower or thunderstorm at any point, often without notice. Much of the state this morning is cloudy but I expect the clouds to begin to move out and also thin out throughout the rest of the morning...
