Milwaukee started Tuesday, June 30, 2026, under clear skies and thick, sticky air, with temperatures already near 79°F and dewpoints high enough to make it feel like a wet blanket outside. The National Weather Service has an Extreme Heat Warning in effect through 7 p.m. CDT Wednesday, July 1, 2026. Highs both days are expected in the low to mid 90s, with heat-index values topping 100°F and a higher risk of heat-related illness.
Afternoon Heat And Gusty Southwest Winds
Forecasters expect highs around 93°F on Tuesday and near 95°F on Wednesday, with heat-index readings making it feel like the low 100s. Southwest winds of 10 to 15 mph with gusts up to 25 mph will add a bit of breeze but not much relief. The Extreme Heat Warning and forecast details come from the NWS Milwaukee. Anyone working outdoors is urged to schedule the toughest tasks for the morning, take frequent breaks in air-conditioned spaces, and watch for signs of heat exhaustion.
Storm Chances Later This Week
Shower and thunderstorm chances creep back into the picture later in the week, with storm clusters possible Thursday night into Friday and scattered storms likely into the holiday weekend. Most storms should remain scattered, but Friday currently looks like the best bet for measurable rain, with localized totals between one tenth and one quarter of an inch. If you are planning outdoor events for Saturday, July 4, keep an eye on updated forecasts, since periodic downpours could briefly interrupt the festivities.
Where To Cool Off
For residents without reliable air conditioning, the City of Milwaukee keeps an updated list of cooling sites, public pools, and splash pads. Check the city’s page for locations and hours. Details are available from the City of Milwaukee, or you can call 211 for assistance. Health officials recommend staying hydrated, avoiding the midday sun when possible, and checking in on older neighbors, young children, and pets while the heat wave lasts.
