According to the National Weather Service, a rare summertime cold front will dive into south GA this afternoon, developing strong to isolated severe thunderstorms by the early evening hours across southeast GA.
The main threats with this activity will be damaging wind gusts of 40-60 mph, heavy downpours and frequent lightning strikes. A few strong thunderstorms will also be possible along the Interstate 95 corridor in northeast Florida late this afternoon. The cold front will then sink southward to the FL/GA border overnight tonight, and a widespread heavy rainfall event is setting up for locations south and east of Waycross and Jesup, where waves of heavy downpours and embedded thunderstorms will push northeastward from the northeast Gulf of Mexico across our area. Rainfall totals of 2"-3" are expected for locations south and east of Waycross and Jesup, with locally higher totals possible. A weak low pressure center may also develop over the northern Gulf of Mexico late this week, possibly keeping the threat for heavy rainfall through Friday. Widespread clouds and rainfall will keep highs in the 80s from Wednesday through Friday region-wide.
Meanwhile, the remnants of Tropical Depression #3 have dissapated, and are moving northward over the Gulf Stream waters east of the east central Florida coast early this morning. This former depression will not bring any impacts to our region today and will accelerate north-northeastward ahead of the approaching cold front tonight and Wednesday.
