.Near Term.../through Friday/...

Low pressure will move to the northeast Today. Remnants of slow 
moving Nicholas will continue over Louisiana Today, with a warm 
front extending east from it. Troughing will extend from the low to 
the northeast, to this warm frontal boundary, yielding an extended
frontal zone. Early in the day, expect the best rainfall coverage 
along and north of the frontal zone across SE GA, but coverage and
intensity of the convection will increase in the afternoon, 
especially in the warm sector across NE FL. 

While convective coverage will decrease overnight with the loss of
diurnal heating, the presence of the frontal zone will keep a few 
showers around. 

The low to the northeast will continue to track north northeast 
Friday, while the remnants of Nicholas to the west will move little.
Moisture will continue to move east across the region along the 
lingering frontal zone, yielding another day with higher convective
coverage. The frontal zone is expected to move a little north 
during the day, which will help bump temperatures up. 

Temperatures will trend a little below normal Today, then near 
normal for Friday.       

&&

.Short Term.../Friday night through Sunday night/...

High pressure will build to the north this period, with an inverted
trough developing over forecast area. Ample moisture will remain in 
place this period, leading to a period of above normal precipitation
chances. 

Temperatures are expected to trend near normal this period. 

&&

.Long Term.../Monday through Wednesday/...

High pressure will build to the northeast this period, leading to a
prolonged stretch of onshore flow. Moisture will remain across 
area, so above normal precipitation chances to continue. 

Temperatures will trend near to a little below normal this period. 

&&

.Marine...

Low pressure will track to the north northeast over the next few 
days, with a trough from it laying southwest across area and 
connecting to a warm front which extends east from the remnants of
Nicholas to the west. High pressure will build to the north over the
weekend, as an inverted trough develops over forecast area. The high
will build more toward the northeast early next week into mid week. 

Rip Currents: SE GA: Moderate Today, Low Friday
              NE FL: Moderate through Friday
