This is what was gawx was talking about earlier.A surface trough interacting with an upper-level low is producing a
broad area of disorganized showers and thunderstorms about 600 miles
east-southeast of the Georgia coast. Surface pressures remain high
across the area, and significant development of this system is not
anticipated due to dry air and unfavorable upper-level winds. The
disturbance is expected to move westward today, and then
west-northwestward at about 15 mph on Monday, reaching the coast of
the southeastern United States by late Monday.
