A frontal boundary will become stationary across the region later today and tonight. A low pressure system will move east along this boundary on Wednesday. As this Low moves through our region, isolated thunderstorms are expected to develop along and south of it. A few strong thunderstorms will be possible over Northeast Florida from Wednesday afternoon through late Wednesday evening.
Also, as this low tracks east, colder air will move in from the north across Southeast Georgia. There is a great deal of uncertainty as to the strength and timing of the cold air at this point, but there is a low chance for light freezing rain or snow near the Altamaha River ends early Thursday morning, if the cold air sinks in before the precipitation moves out of the area. No accumulation is expected.
A few of the thunderstorms may become strong or severe with a chance of strong winds or hail. In addition, some storms could contain rotation which will enhance the chance of a brief isolated tornado…with the best chance of this over our southernmost counties in northeast Florida…e.g. Marion, Putnam, Flagler. Widespread rain and showers will overspread the region Wednesday and early Thursday with rainfall totals ranging from half an inch to around 1.5 inches over parts of inland Southeast Georgia.
The National Weather Service will continue to monitor forecasts, and will provide updates as needed. If expectations change and support a more substantial hazard for our area of responsibility, a n additional email will be sent out by your weather team at the National Weather Service.
