Wisconsin Summer Weather Alert: Hail, Thunderstorms, and Wildfire Smoke Collide Monday Afternoon

A Wisconsin Summer Weather Alert has been issued for the Green Bay area, and if you’ve got plans outdoors on Monday afternoon, you’ll want to pay close attention. Forecasters are tracking a round of thunderstorms expected to sweep through the region—bringing the chance of gusty winds and small hail, especially along the busy U.S. 41 corridor.

While this isn’t shaping up to be a dangerous severe weather event, it’s one of those afternoons where you’ll be glad you checked the forecast. These summer storms could develop quickly after 1 PM and bring a short but punchy round of rain, lightning, and even hail about the size of peas in certain spots. If you’re driving, gardening, or working outdoors, you’ll want to be ready to duck for cover—or at least grab a sturdy umbrella.

What You Can Expect on Monday

Temperatures will dip slightly below average for this time of year, with highs in the low to mid-60s. It’ll feel cooler and breezy, with winds gusting up to 24 mph. That wind, paired with developing storm cells, sets the stage for some quick-hitting afternoon storms.

The Wisconsin Summer Weather Alert especially highlights areas near U.S. 41 in Green Bay, where the environment looks most favorable for isolated storm cells to develop. These storms may produce brief bursts of small hail, especially during the mid- to late-afternoon window. While we’re not expecting widespread damage, even minor hail can dent cars, harm gardens, and make driving slippery.

What Makes This Alert Worth Paying Attention To

What makes this alert important isn’t just the storms themselves—it’s how they might catch you off guard. The weather could shift quickly, turning what looks like a calm, breezy afternoon into a stormy, noisy one. And if you or your kids have plans to be outdoors after lunch—sports practice, errands, or heading home from school—it’s worth planning ahead.

Smoke drifting in from Canadian wildfires could also worsen air quality in the area, so it’s a good idea to limit time outside, especially if you or someone in your family has asthma or other respiratory conditions.

What You Can Do Now

• Check the weather before heading out Monday afternoon.

• Delay errands or commutes if you can—especially around 1 to 5 PM.

• Bring in or secure outdoor items like garden tools, lawn furniture, or toys.

• Have a backup indoor plan for kids or pets who normally spend time outside.

The good news? The storms will likely move out by evening, and the rest of the week looks brighter and warmer—just in time to enjoy some true early summer weather.

FAQ About Wisconsin Summer Weather Alert

1. So, what’s the deal with this Wisconsin Summer Weather Alert? Should I be worried?

Not panicking territory—but definitely something to pay attention to. Monday afternoon, we’re looking at some pop-up thunderstorms in the Green Bay area. They could come with gusty winds and little bits of hail—nothing extreme, but enough to make a mess of your afternoon if you’re caught outside. It’s more about being ready than being scared.

2. When are these storms actually going to show up?

Most likely after 1 PM, right into the afternoon hours. That’s when the air gets unstable enough for storms to form. If you’re planning a grocery run, walk with the dog, or anything outside—try to wrap it up before lunch if possible.

3. Is the hail really something I should be concerned about?

It’s not baseball-sized or anything dramatic, but small hail—about pea-sized—can still be a pain. It might ding up your car or flatten your garden plants if you leave them unprotected. If you’ve got a garage or a place to stash outdoor stuff, now’s the time to use it.

4. I’ve got kids’ sports practice and errands—do I need to cancel everything?

Not necessarily, but you’ll want to have a backup plan. If the storms roll through while you’re out, it could mean soggy shoes, slippery roads, or delays getting home. Try to shift outdoor things to the morning, or just be flexible in the afternoon.

5. Is the rest of the week going to be like this too?

Actually, things are looking up after Monday. Once these storms clear out, we’re expecting sunnier skies and warmer temps heading into midweek. So if Monday’s a little messy, just know summer’s still on track to show up right after.
