This article provides a concise forecast for Wisconsin’s weekend through midweek. It highlights a sequence of low-pressure systems that bring scattered showers, thunderstorms, and patchy fog.
Forecasters warn of an elevated severe weather risk on Monday and again Tuesday, with the potential for tornadoes along a warm front, damaging winds, large hail, and heavy rainfall. The article also maps timing, expected temperatures, wind, and practical safety steps for residents preparing for these storms.
Weekend and Early-Week Storms: What to Expect
Scattered showers and thunderstorms are likely Sunday night, especially across southeastern Wisconsin. Patchy fog could form overnight as the first of several low-pressure systems sweeps through the state, reducing visibility in places.
By Monday morning, most showers should clear. However, the overall pattern remains unsettled as another system approaches.
Forecasters emphasize that an Alert Day is possible on Monday as the atmosphere may or may not cap. As a warm front progresses northward, the exact evolution will determine how storms behave along that front, including whether a few could briefly turn tornadic before transitioning to other hazards.
Monday’s Severe Weather Threat
- An Alert Day has been issued for Monday due to uncertainty about whether the atmospheric cap breaks and how far north a warm front advances.
- Storms near the warm front could start as isolated tornadoes, then shift to a greater risk of damaging winds and large hail.
- Expect heavy rainfall in spots and brief strong gusts that could cause localized wind damage or power outages.
Midweek Risk: Tuesday and Beyond
The midweek period keeps the storm threat alive as Monday’s low departs and another low-pressure system tracks through the region. The pattern favors continued rounds of showers and thunderstorms with several hazards possible as the systems interact with remnant warm, moist air.
Forecasters caution that Tuesday is also an Alert Day since conditions could re-flare into all the severe-weather modes. There is even the possibility that a third low-pressure system tries to re-enter the Midwest by Wednesday, keeping scattered showers and storms in the forecast through the middle of the week.
Tuesday and Wednesday Hazards
- Tuesday could bring renewed thunderstorm potential with a risk of all severe hazards, including tornadoes, damaging winds, large hail, and heavy rain.
- A third low-pressure system may attempt to re-enter the Midwest on Wednesday, maintaining the chance of widespread showers and thunderstorms.
- Residents should monitor multiple channels for updates, as timing and intensity can shift with small changes in the upper-air pattern.
Safety, Preparedness, and Forecast Details
With several rounds of storms possible, preparedness is essential. Have multiple ways to receive severe weather alerts and a clear safety plan for Monday and Tuesday.
Safety and Readiness Tips
- Sign up for NOAA Weather Radio, smartphone alerts, and local emergency broadcasts to stay informed of warnings and watches.
- Identify the safest place in your home or workplace, and practice a quick plan with family or coworkers.
- Secure loose outdoor items, check your emergency kit, and keep a flashlight, batteries, and a supply of water and nonperishable food on hand.
- Charge mobile devices in advance and have a backup power source if outages are possible.
Temperature, Winds, and When Relief Arrives
Temperatures are expected to rise into the mid- to upper-70s early next week. Overnight lows will mainly be in the 50s to 60s.
By Wednesday, highs may dip to the low 70s. Temperatures are expected to fall into the 50s by the weekend as cooler, drier air moves in to end the active storm pattern.
Winds will be gusty at times. Southwest winds could reach up to 30 mph Sunday night, with generally 10–20 mph winds expected through the period.
