This article summarizes an upcoming weather pattern across forecast-for-madison-and-southern-wisconsin/”>southern Wisconsin and the surrounding Midwest. It highlights when showers and potential severe storms may occur, temperatures, wind, UV exposure, and practical safety steps as the pattern evolves into early next week.
Overview of the Emerging Weather Pattern
Forecasters point to scattered showers and thunderstorms starting Thursday night into Friday morning. Conditions will ease by Friday’s dawn.
Friday is expected to bring warmer air, with temperatures climbing into the upper 70s to lower 80s and partly sunny skies. Another wave of showers and thunderstorms is possible late Friday into early Saturday, and one or two storms could become severe.
Sunday and especially Monday look to host the highest risk of severe weather, as a large low-pressure system traverses the Midwest. The southern half of Wisconsin faces the most significant threat, including the possibility of tornadoes.
Lingering showers and storms may persist into Tuesday before a return to quieter conditions by midweek. Daytime highs are forecast in the mid-60s to mid-80s, with overnight lows generally from the 40s to the low 60s.
Thursday Night into Friday Morning: Showers and Clearing
Showers and thunderstorms are expected to be scattered during the Thursday night to Friday morning window, with conditions gradually clearing by early Friday. Expect damp roads and isolated downpours in the pre-dawn hours. Conditions shift toward improvement as the sun rises on Friday.
Key details for Thursday/Friday morning:
- Early showers give way to clearing skies by Friday morning.
- Temperatures rise into the upper 70s to around 80 degrees by daybreak.
- Winds remain light to breezy, with a south-southwest flow developing into the afternoon.
Friday and Friday Night: Warm Day with a Late-Week Rain Threat
Friday should be a mix of sun and clouds, with highs in the upper 70s to lower 80s and mostly pleasant conditions. The atmosphere may destabilize again late Friday afternoon into Friday evening, bringing another round of showers and thunderstorms into Friday night and early Saturday.
One or two storms Friday night could be severe, though coverage is uncertain and depends on moisture return and the timing of a weather front. Individuals should remain weather-aware and have a plan for quickly seeking shelter if warnings are issued.
Forecast highlights for Friday night:
- Possible late-day to overnight thunderstorm development.
- Confidence in severe weather is lower than for the Sunday-Monday window, but cannot be ruled out.
- Otherwise, the weather trend will tilt toward clearing early Saturday.
Sunday into Monday: Peak Severe Weather Potential
The most significant threat unfolds Sunday into Monday as a large low-pressure system sweeps through the region. Sunday marks the onset of elevated risk that intensifies across southern Wisconsin on Monday, with the potential for all severe hazards including tornadoes, damaging winds, large hail, and flash flooding in the strongest cells.
Residents should monitor forecasts closely and be prepared for rapid changes. The greatest concentration of severe weather may occur Sunday night through Monday, with a tapering trend by Tuesday if the system moves through as forecast.
Temperatures, Winds and UV Index
Across the week, daytime highs span from the mid-60s to the mid-80s. Overnight lows will be mostly in the 40s to low 60s.
Winds will be breezy at times, with gusts up to about 25 mph anticipated Friday. A generally south to southwest flow is expected through the period.
UV indices are expected to be high to very high early in the period, then drop to moderate by Monday as the clouds increase and the system approaches. People spending time outdoors should apply sun protection during peak sun hours and be prepared for rapidly changing cloud cover as storms approach.
What to Do and How to Stay Safe
With the threat of isolated to widespread severe storms, especially Sunday into Monday, residents should stay tuned to local forecasts and NOAA Weather Radio.
Have a plan for weather alerts, know your safest shelter location, and secure outdoor items that could become projectiles in gusty winds.
Practical steps include reviewing storm safety procedures, checking your emergency kit, and ensuring you have a way to receive warnings during outdoor activities or travel.
Expect changing conditions from Thursday night through early next week, with the most dangerous period likely Sunday into Monday.
Stay weather-aware, especially if you’re in southern Wisconsin, and be ready to take shelter if a severe weather warning is issued.
