ALT A map of the severe weather outlook for this afternoon, June 10, showing a level 3 out of 5 risk across the Upper Mississippi River Valley.
A widespread heat wave will build across the central U.S. through midweek before shifting to the East Coast, where it peaks on Friday, then slowly ease over the weekend.
An early season heatwave can often be more dangerous and pose a greater risk for heat-related illness. This will be the most significant heat so far this summer for many locations.
The most important things you can do in significant heat are to stay hydrated and interrupt your exposure to the heat by taking breaks out of the sun and/or being in cooled locations.

Following record-breaking rainfall in April, Wisconsin entered May largely free of drought concerns.
Now, moderate drought (D1) has returned to 13.5% of the state, with abnormal dryness (D0) covering a vast majority of Wisconsin.
Heat can be more dangerous than many realize, but every heat-related illness and death is preventable.

Milwaukee is a prime example of Wisconsin's precipitation ping-pong pattern.
After recording its wettest April on record (9.49"), Brew City swung to its driest May, receiving just 0.36" of precip all month. That's 3.18" below the amount Milwaukee typically receives in May.
May was a stark change from April. Severe weather was less frequent, and dry conditions quietly returned.
We'll have a full May Climate Summary available in the coming weeks. In the meantime, check out our latest blog to see what summer might have in store.
After a record wet April, things have been dry this month.
Abnormally dry conditions are expanding across western and southeastern Wisconsin in the latest Drought Monitor.
With below normal precipitation more likely than not over the next 10 days, expect this to continue.
With summerlike heat in the forecast, take a look at Wisconsin's summer 2026 outlook.
Current guidance suggests a slight lean toward drier-than-normal conditions in northwest Wisconsin, while temperature signals remain uncertain.

Thinking about Wisconsin's last spring freeze?
