EAU CLAIRE, Wisconsin — A heat advisory is now in effect from noon today until 8 PM CDT across Rusk, Chippewa, and Eau Claire counties. The National Weather Service warns that heat index values could approach 100 degrees.

High temperatures and humidity may lead to heat-related illnesses. Residents are advised to drink plenty of water, stay indoors in air-conditioned spaces, and check in on friends and neighbors.

The humidity surged on Thursday, with dew points climbing to the mid-60s after several cooler days. Daily highs reached the low 90s in the Chippewa Valley and mid to upper 80s in the surrounding areas.

As the warm weather continues into the holiday weekend, Friday’s forecast warns of heat index levels nearing 100 degrees, with dew points around 70 to possibly 75 degrees. It is crucial for people celebrating Independence Day to remain hydrated.

Forecasters recommend drinking water frequently throughout the day, even before thirst sets in. Avoiding dehydrating beverages like caffeinated drinks, alcohol, and sugary sodas is also encouraged.

While there may be a few isolated showers or thunderstorms on Friday, most precipitation is expected in the early morning hours. The chance for significant storm activity may increase on Saturday, particularly in the afternoon and evening.
