Severe Storms to Hit Southern Wisconsin: What You Need to Know

A strong storm system is moving into southern Wisconsin, bringing with it a chance of severe thunderstorms, hail, and gusty winds. The National Weather Service has issued a First Alert Day for the region, warning residents to be prepared for the potentially dangerous weather. The storms are expected to develop over northern Wisconsin during the afternoon and track southeast into the area between 6 and 10 p.m.

The atmosphere is primed for the development of organized storms, with sufficient wind shear and instability to support the formation of hail and strong wind gusts. The main concern for residents will be the potential for frequent lightning, hail, and gusty winds, which could cause damage to property and disrupt daily activities. While the storms are expected to weaken after sunset, they will still pose a threat to the area, and residents are advised to stay indoors and avoid travel unless absolutely necessary.

Despite the severe weather threat, the weekend is expected to be pleasant, with high pressure building in behind a cold front and bringing dry conditions to the region. Temperatures will be mild, with highs in the low to mid 80s inland and cooler temperatures near the lake. However, the dry conditions will be short-lived, as thunderstorm chances return to the forecast on Monday afternoon and evening.

The bigger story for next week will be the building heat, as a strong ridge of high pressure builds over the upper Midwest, allowing hot and humid air to settle over the region. High temperatures will climb into the 90s by Wednesday and Thursday, with some areas potentially reaching the mid to upper 90s. When combined with dewpoints in the low to mid 70s, heat index values will likely reach between 100 and 105 degrees, prompting heat advisories and posing a significant threat to public health.

Looking ahead, the combination of heat, humidity, and instability in the atmosphere will provide the fuel for scattered thunderstorm chances to continue each day through late next week. While the exact timing and location of these storms will be difficult to predict, residents can expect a more summer-like pattern to develop, with warm temperatures and occasional thunderstorms.

In preparation for the severe weather, residents are advised to stay informed about the latest forecast and warnings. The National Weather Service and local news outlets will provide updates and alerts as necessary, and residents can download the WMTV15 News app or the WMTV15 First Alert weather app to stay ahead of the storm.

With the severe weather threat and heat wave on the horizon, it is essential for residents to take precautions to stay safe. This includes staying indoors during severe weather, staying hydrated during the heat wave, and checking on vulnerable neighbors and loved ones. By taking these steps, residents can minimize their risk and stay safe during the upcoming storm and heat wave.
