JACKSONVILLE, Fla. – If you’re planning to head outside for Fourth of July festivities in Northeast Florida, you’ll want to keep a close eye on the sky and maybe have a backup plan ready. Isolated showers in Southeast Georgia are possible, as well.
Storms could put a damper on celebrations in southern counties
The biggest weather concerns for the holiday are centered around Marion, Putnam, and Alachua counties, where the chances for heavy rain and strong storms are highest. Parts of southeast Georgia could also see some storms, though coverage there is expected to stay limited.
Storms that do develop could pack a punch. Slow-moving cells combined with plenty of moisture in the atmosphere could lead to heavy downpours and localized flooding. Strong storms may also bring frequent lightning and gusty, unpredictable winds — so if you hear thunder, head inside.
The good news? Storm activity is expected to taper off after sunset. However, scattered showers and storms could linger into the mid-to-late evening hours inland, so that fireworks show isn’t completely in the clear just yet.
Dangerous heat adds to the holiday hazards
The storms aren’t the only thing to watch out for. Temperatures on the Fourth are forecast to climb into the mid-to-upper 90s, and when you factor in the humidity, it’s going to feel even hotter. Heat index values, the feels-like temperatures, are expected to reach 102 to 107 degrees in many areas.
Overnight, temperatures won’t offer much relief. Most inland areas will only cool down to the lower-to-mid 70s, while coastal spots stay in the upper 70s. There’s also a chance of patchy light fog in some inland areas, both this morning and again late tonight.
Heat concerns stretch into the weekend, early next week
The heat isn’t going anywhere fast. Heading into Sunday and Monday, inland areas can expect high temperatures to stay in the mid-to-upper 90s, with coastal areas seeing highs in the upper 80s to lower 90s.
Overnight lows will settle in the mid-70s inland and the upper 70s along the coast and near the St. Johns River. Heat index values are expected to surpass 100 degrees again, and a Heat Advisory could be issued for Sunday and Monday.
Stay safe this holiday weekend
Whether you’re watching fireworks, grilling out, or hitting the beach, make sure you’re staying hydrated, wearing sunscreen, and watching for storm updates throughout the day.
