Good news if you didn’t want a soggy Wednesday, but bad news if you wanted more soaking rains. The heaviest rain potential has dropped south of the Cheddar Curtain and we’re looking at only 0.1 - 0.5” of rain today. It’s not an all day rain and the heaviest rain will be in scattered pockets.

Learning about the Wisconsin portion of the VORTEX-USA project, seeing how the state compares to others with respect to how we receive and respond to weather warnings. After this is a panel discussion about the 2025 flooding.

Still time to stop by the Wisconet poster at the @ametsoc.org Madison Summit to learn about our web development philosophy and how we create tools for expert and non-expert users.

We could not buy a drop of rain in July. Now, southern Wisconsin is in line for another 1-2 inches of rain this week, with most of it falling Wednesday. There’s a Level 2/4 risk of excessive rainfall on Wednesday, including Madison, Milwaukee, and Fond du Lac.

We’re looking forward to seeing everyone this week at the @ametsoc.org Madison Summit! Stop by the poster session tomorrow to talk to our program manager and front end developer. Be sure to bookmark wisconet.wisc.edu as your one-stop-shop for Wisconsin weather information while you’re in town!

As the rain winds down, we see widespread 2-4 inch totals across southern Wisconsin…much needed rainfall after a very dry July. A side benefit is that the sky looks a little bluer than it has In the last couple weeks. The rain has helped clear out remnant smoke particles.

And there was much rejoicing from the lawns, gardens, and watersheds, as a steady rain fell across southern Wisconsin. Widespread 2-4” totals have been measured by Wisconet and CoCoRaHS observers in the last 24 hours.

The forecast is looking good for heavy rain along and south of I-94, with 1-3 inches possible. Lower totals further north. With as dry as its been, the rain may not soak into the soil initially, so watch for ponding in low-lying areas. Current radar: wisconet.wisc.edu

Drought continues to spread across Wisconsin as our dry July winds to an end. Shallow-rooted plants need irrigation, as plant available water through 8" is approaching zero. Southwestern Wisconsin has a chance for heavier rain tomorrow, but not enough where it's needed most.

It is uncommon to see strong tornadoes in the morning in Wisconsin. Looking back from 1950 through April 30 of this year, the prime time for strong tornadoes in Wisconsin is between 2 and 7 pm (CST). Yesterday's tornado began at 10:56 am CST, making it just the 10th to start during that hour.

NWS-Green Bay rated the Appleton-Menasha tornado a preliminary EF3, with maximum estimated winds of 140 mph. Since 1950, per NCEI storm events database, that's only the 4th tornado rated F/EF3+ in either Outagamie or Winnebago Counties. The last one, there, was April 27, 1984.

Today is a much cooler, less humid, and calmer day. The eastern half of the state saw quite a lot of rain and severe weather yesterday, so the quieter day will allow for clean up and the tornado survey in Appleton, Menasha, and Neenah to finish.

We've received reports of another lightning fatality in Wisconsin this morning. This would be Wisconsin's 2nd lightning fatality of 2026 and 3rd in the last two years. The victim was trimming trees when a thunderstorm developed nearby. www.wmtv15news.com/2026/07/27/2...

29-year-old man dies after suspected lightning strike in Whitewater

Whitewater Fire and EMS responded around 10 a.m. to the 400 block of South Elizabeth Street in the City of Whitewater for a person stuck in a tree, possibly struck by lightning.

Beyond the severe thunderstorms, extreme heat continues. Wisconet has a new network record for heat index, as we've hit 118°F at our stations in La Farge and Montello.

Lots of severe weather ongoing today across eastern Wisconsin and there is now a tornado that has hit parts of Appleton. Stay weather aware this afternoon and seek shelter immediately if warnings are issued!

It's a busy weather map this morning, with extreme heat in southern Wisconsin, severe storms in northeastern Wisconsin, and bad beach conditions along the lakeshores. Today's a good day to stay in the air conditioning and watch the Wisconet data! wisconet.wisc.edu

Tropical dewpoints across Wisconsin this morning.

It's as humid as a jungle though. All my windows have a lot of condensation. Lucky me to have air conditioning.

As expected, most of us did not get much rain over the weekend, but our Luxemburg station did manage to get a little more than half an inch of rain. Keeping an eye on the storm complex that's just on the Wisconsin-Michigan border and for additional development this afternoon.

Today’s heat and humidity will provide some of the ingredients necessary for severe weather. Most of Wisconsin is in a Level 3/5 risk for severe weather for this evening and overnight. Damaging winds are the main threat, but the Northwoods could see large hail and tornadoes.

Very humid morning, with dewpoints at least 10 degrees higher than they were 24 hours ago over southern Wisconsin. The high humidity coupled with warm temperatures means that we’re expecting heat indices over 100 for most of the state today. Drink plenty of water!

Heat Advisories and Extreme Heat Warnings in place across all but northeastern Wisconsin for tomorrow. Heat indices could reach 110 across the Extreme Heat Warning and above 100 in the Heat Advisory. Drink plenty of water and avoid strenuous outdoor work tomorrow.

Scattered rain and thunderstorms return to Wisconsin this weekend. Don’t get your hopes up about widespread heavy rain and drought busting, but some of us will see some light rain accumulations hitting the gauges. Some storms tomorrow could have gusty winds and large hail.

Six months ago, it was -41.6°F at our weather station in Knight. 11 days ago, Knight hit 95.5°F. A difference of 137.1 degrees! Here's how the rest of the state stacks up for the difference between the lowest January temperature and the highest July temperature.

We knew our cooldown wouldn't last forever, and we've got an Extreme Heat Watch in place for most of western Wisconsin for Sunday and southwestern Wisconsin for Sunday and Monday. Heat indices up to 105°F possible. Keep tabs on the heat: wisconet.wisc.edu/data/maps

"Another problem stems from the distribution of air-pollution sensors around the country." Mesonets can expand the distribution of air-pollution monitoring - if a high-quality, reasonably-priced sensor were to be commercially available.

As wildfires continue to get bigger and more frequent, humans need a better way to know how safe it is to be outside, Dan Engber argues.
