Strong Thunderstorms Possible Across Western Wisconsin
A Special Weather Statement is highlighting the potential for impactful weather across Jackson County, Trempealeau County and Clark County, Wisconsin, as thunderstorms develop across parts of western Wisconsin.
The National Weather Service in La Crosse is monitoring the region for scattered strong to severe thunderstorms late this afternoon and evening. (National Weather Service)
While not every storm will become severe, residents should remain weather-aware as conditions evolve through the evening.
What Weather Is Possible?
Thunderstorms developing across the region could produce:
- Strong, gusty winds
- Frequent lightning
- Heavy rainfall
- Small to potentially larger hail
- Brief reductions in visibility
- Localized flooding in areas receiving repeated heavy downpours
The primary concern is that storms could strengthen quickly as they develop.
Jackson County
Jackson County, including communities around Black River Falls, should monitor changing skies and radar trends. Strong thunderstorms could bring sudden wind gusts, lightning and periods of heavy rain.
Trempealeau County
Trempealeau County remains within the area being monitored for late-day thunderstorms. Residents and anyone traveling through the county should be prepared for rapidly changing conditions.
Clark County
Clark County is also included in the area of concern. Storms moving across the region could produce gusty winds, lightning and heavy rainfall.
Why Are Storms Developing?
Late-summer thunderstorms can become stronger when warm, humid air combines with atmospheric instability and sufficient wind shear.
According to the National Weather Service’s latest outlook, scattered strong to severe storms may develop during the late afternoon and evening across west-central Wisconsin. (National Weather Service)
Because thunderstorms can intensify quickly, conditions can change considerably over a short period of time.
Travel and Outdoor Safety
If thunderstorms develop, avoid unnecessary outdoor activities until storms have passed.
If you hear thunder, move indoors. Lightning can strike well away from the heaviest rainfall.
Drivers should also be prepared for:
- Sudden heavy rain
- Water covering roadways
- Reduced visibility
- Strong crosswinds
- Falling tree limbs
Never drive through a flooded roadway. Turn around and find another route.
Radar Watch HQ Weather Tip
Keep weather alerts enabled on your phone and monitor local radar as storms approach. A storm that appears weak several miles away can strengthen rapidly as it moves into a more favorable environment.
The National Weather Service continues to monitor the threat across west-central Wisconsin, with scattered strong to severe storms possible through the evening. (National Weather Service)
