The two major models continue to differ in the short-term forecast guidance. The NAM forecast model suggests a drier frontal passage while the GFS shows more moisture and greater precipitation. The NAM seems to be too dry and the GFS looks more likely but because of the disparity between the two solutions I am guessing we will experience a hybrid of them.
A slight risk of rain will exist today (12/30) but the greater chance will exist tomorrow as the bulk of the low-level moisture enters the area. Throughout the day on Thursday, there will be a chance of rain showers and as the day progresses, chances of precipitation will rise. By 10PM (12/31), the front will enter eastern Georgia and the last of the precipitation will exist the coast by early Friday morning.
Temperatures around the area will reach approximately 58°F on Thursday. Friday morning, the low will drop to about 52°F on the islands and 49°F inland. During the day Friday, 59°F will be the high temperature and winds will pick up to around 15 - 20mph from the West.
Expect cold temperatures, even on the islands, this weekend and early next week with lows possibly creeping down to 25°F on Tuesday morning.
Happy New Year!
