It will be hotter than a firecracker this weekend as the Fourth of July approaches, with temperatures in triple digits and heat indices reaching dangerous levels.National Weather Service meteorologist Frank Alsheimer said the temperature is expected to reach 104 in the Bulloch County area today, with a heat index of 115 degrees. Sunday will be just a bit cooler, with a high of 102 and heat index of 113 degrees, he said.The kicker is the humidity. According to the National Weather Service, there is a slight chance of afternoon thunderstorms Sunday, but Alsheimer said while the rain may cool things down a few degrees, the humidity will make it feel just as steamy.The heat, expected to be high in July, comes from a “dome of heat moving eastward into Georgia” from a system coming from the Midwest, he said.As the holiday approaches, temperatures may cool down to the high 90s, with slight chances of rain, and more high humidity, he said.Bulloch County 911 Director Kelly Barnard reminded people to stay indoors during the hottest part of the day, drink plenty of fluids should you have to be outside, and make sure pets, older residents and disabled people are cool.Animals should have fresh water and shade, and checking on them as well as ensuring at-risk people are safe is a good idea, she said.Holli Deal Bragg may be reached at (912) 489-9414.
