A prolonged stretch of dangerous summer heat will continue across Chattooga County and Northwest Georgia through the Independence Day weekend, with afternoon temperatures climbing into the mid to upper 90s and heat index values frequently topping 100 degrees.

A Heat Advisory remains in effect today from noon until 8 PM, with heat index values expected to reach 105 degrees across the area. Today’s high will be near 97, and while skies will remain sunny, the combination of heat and humidity will create hazardous conditions for anyone spending extended time outdoors.

The extreme heat eases only slightly Wednesday through Friday. High temperatures will remain in the mid-90s, while heat index values are expected to range from the upper 90s to around 103 degrees. A few locations could still briefly reach 105 degrees during the hottest part of the afternoon.

Beginning Wednesday, isolated afternoon and evening thunderstorms will return to the forecast. Rain chances remain relatively low through Friday, ranging from 20 to 30 percent, but any storm that develops could produce gusty winds, frequent lightning and brief heavy rainfall.

Looking ahead to the Fourth of July weekend, temperatures will remain well above normal with highs around 95 degrees Saturday and 93 degrees Sunday. Afternoon and evening thunderstorms will become more numerous, with rain chances increasing to 30 percent Saturday and 50 percent Sunday. By Monday, scattered showers and thunderstorms are expected to become even more widespread, with rain chances climbing to 60 percent as a weather pattern change begins to take shape.

Residents planning outdoor activities this week or attending Independence Day celebrations should stay hydrated, wear lightweight clothing, take frequent breaks in the shade or air conditioning, and never leave children or pets inside parked vehicles. Those working outdoors should schedule strenuous activities during the morning hours whenever possible and remain alert for signs of heat-related illness.
