Southern Wisconsin should prepare for a renewed stretch of summer heat early next week, with daytime highs forecast to climb into the low 90s from Monday through Wednesday, according to WMTV. The station flagged those days as First Alert Days because heat and humidity will create elevated heat-related health risks for some residents.
What to expect this weekend
WMTV reports a few very isolated storms remain possible this Friday afternoon, mainly across southern parts of the region. Those brief storms could produce lightning and locally heavy rain but should fade near sunset. Once the showers move out, skies are expected to clear overnight.
Saturday looks quiet with mostly clear skies and temperatures near seasonal norms. Forecasters note a possibility of patchy fog Saturday morning, chiefly in western counties, as light winds and clearing skies create conditions for reduced morning visibility. Travelers are advised to allow extra time if driving early.
Heat returns early next week
A strong ridge of high pressure is forecast to build over the region heading into early next week, WMTV said, setting up several days of hot weather. While dew points are expected to be somewhat lower than during the previous hot spell this summer, humidity will still make conditions feel warmer.
| Time frame | Outlook |
|---|---|
| Friday (late) | Isolated storms; clearing after sunset |
| Saturday | Mostly clear; patchy morning fog possible |
| Monday–Wednesday | Highs in the low 90s; heat index values into the lower–mid 90s |
WMTV warned the combination of heat and humidity could push heat-index readings into the lower- to mid-90s on the hottest days. That level of heat can be stressful for infants, older adults and people with chronic medical conditions, as well as those who work outdoors.
- Stay hydrated and take frequent breaks in the shade if you must be outside.
- Check on neighbors, relatives or others who may be more vulnerable to heat.
- Be mindful of early-morning fog if traveling Saturday.
Forecasters say storm chances remain low through much of next week while the high-pressure ridge holds. Residents with outdoor plans should monitor local updates in case timing or intensity of the heat or any isolated storm risk changes.
