Near Term

Main Highlights: Through Tonight

- High Risk for Rip Currents - Coastal flooding potential

For Today, high pressure to the north will strengthen as an inverted trough begins to develop to the east southeast of the area. The high to the north will continue to strengthen to the north Tonight, with the inverted trough also strengthening. Between the high and trough, an elevated northeast flow is expected. Winds will begin to pick up Today, and continue through Tonight, being most noticeable at the coast.

Coastal hazards will increase this period due to the strengthening onshore flow.

Temperatures will be below normal Today, despite sunshine. With the onshore flow, there will be a wide range of temperatures Tonight, as the coast will have lows in the mid 60s, with upper 40s over interior SE GA.

Strong high pressure over the Mid-Atlantic region early on Monday will slowly settle southward while gradually weakening through midweek. Meanwhile, deep troughing initially in place along the southeastern seaboard will likely cutoff over the Bahamas, with lowering surface pressures to the south of our region keeping a relatively tight local pressure gradient in place on Monday and Tuesday. A slightly drier air mass will continue to overspread our region, but enough low level convergence will remain in place to occasionally bring showers to coastal northeast FL and the St. Johns River basin. Northeasterly winds will remain sustained in the 25-30 mph range for coastal northeast FL on Monday, where winds will frequently gust to 40-45 mph through around sunset before a gradual decrease begins on Monday night. Otherwise, mostly sunny skies will prevail in the drier air mass for inland southeast GA and the Suwannee Valley, while partly to mostly cloudy skies continue elsewhere on Monday. Highs will again remain in the low to mid 70s, except upper 70s for north central FL and the Suwannee Valley.
