As Florida braces for another sweltering summer day, Jacksonville will face high temperatures and the potential for severe thunderstorms this Sunday, July 27th. With a high near 96°F, coupled with a heat index soaring as high as 105°F, residents are urged to take precautions. The National Weather Service (NWS) has issued a summer weather alert due to the extreme heat and the likelihood of afternoon thunderstorms, which could bring heavy rainfall and localized flooding.
According to the NWS, showers and thunderstorms are expected to develop after 2 p.m. Sunday, with the risk of scattered downpours and lightning. The storms could affect afternoon travel, especially along major roads like I-95 and I-295, where reduced visibility and wet conditions could cause delays. Drivers are urged to slow down and avoid unnecessary travel during the storm’s peak.
While the heat is the primary concern, storms will also increase humidity, making it feel even hotter. Local health officials recommend staying hydrated and avoiding prolonged outdoor exposure between noon and 4 p.m. If possible, limit outdoor activities to early morning or late evening. Ensure pets and family members are indoors during the hottest parts of the day.
Looking ahead, the heat will persist into Monday, July 28th, with temperatures near 99°F and a slight chance of storms in the afternoon. By Tuesday, July 30th, a slight chance of thunderstorms remains, but the heat will continue to push temperatures into the mid-90s.
