AVIATION
(06Z TAFS)
Issued at 214 AM EDT Sun Apr 28 2024
VFR conditions will prevail at the regional terminals. Occasional broken ceilings of 3,500 - 4,500 feet will be possible at the terminals, especially after sunrise. Isolated showers may move onshore from the Atlantic waters after 12Z, but confidence remains too low to indicate anything other than vicinity coverage at the terminals during the daylight hours on Sunday. Cloud cover is expected to decrease towards 00Z Monday. Gusty onshore winds that have been sustained around 15 knots overnight at SSI, SGJ, and CRG will diminish to around 10 knots after 08Z, while easterly surface winds sustained at 5-10 knots elsewhere will diminish to around 5 knots by 09Z. East-southeasterly surface winds will become breezy by 15Z, with sustained speeds of 10-15 knots and gusty at the inland terminals and around 15 knots and gusty at the coastal terminals. Wind speeds will subside substantially after 01Z Monday.
UPDATE
Issued at 721 PM EDT Sat Apr 27 2024
Isolated light rain showers that are more or less sprinkles will continue to push on shore until drier air offshore (PWATS < 1") advects slowly westward and over the region tonight.
Mostly cloudy skies continue as moisture circulates within the upper ridge aloft. The onshore breeze and cloud cover will keep temps mild overnight with lows anticipated to read in the low 60s inland and mid to upper 60s for coastal areas.
The surf zone remains rough via webcams and the onshore flow. There is a High Rip Current Risk in effect through Sunday.
SHORT TERM
(Sunday through Monday night)
Issued at 151 PM EDT Sat Apr 27 2024
Sunday...High pressure ridge axis remains north of the region across the Carolinas and breezy Easterly flow will continue across NE FL/SE GA, with strongest winds at the Atlantic Beaches at 15-20G25-30 mph and mixing down to 10-15G20-25mph over inland areas by the afternoon hours. The onshore flow will continue to keep temps slightly below normal with highs in the mid/upper 70s for the Atlantic Coastal counties and into the 80-85 range over inland areas. While an isolated coastal shower cannot be ruled out, overall measurable rainfall chances will remain in the "silent" 10-15% range with the ongoing forecast.
Sunday Night...Not much change with the pattern other than a slight shift to a Southeast steering flow through the overnight hours which will lead to less wind than is expected tonight and will allow for skies to become mostly clear over inland areas with Strato-Cu clouds still pushing onshore along the Atlantic Coast.
Low temps expected to fall into the upper 50s inland and remain in the 60s along the Atlantic Coast. Slightly less wind and cloud cover over inland areas may lead to some patchy fog development, but chances of any significant fog remain too low to include in the forecast at this time.
Monday...High pressure ridge axis attempts to shift slowly southward into the NE FL/SE GA region which will allow for the steering flow to become more South-Southeast and lead to temps returning to more normal levels with highs in the middle 80s over inland areas and around 80 along the Atlantic Coastal areas. While the SE surface flow will onshore and expect East Coast sea breeze to develop and move inland, there will be a 10-15% chance of a sprinkle or shower as it moves inland, but will continue to keep any measurable rainfall "silent" in the ongoing forecast.
Monday Night...Ridge axis will remain across the region with a light southerly steering flow under Mostly clear skies. Temps will nudge upwards to slightly above normal levels with lows in the lower 60s inland and mid/upper 60s along the Atlantic Coast.
Slightly stronger signal for some patchy late night dense fog by sunrise Tuesday morning over inland areas, but too early to add to the ongoing forecast, but something to monitor.
LONG TERM
(Tuesday through next Saturday)
Issued at 151 PM EDT Sat Apr 27 2024
Tuesday...The newer 12Z GFS/NAM model runs are suggesting a weaker frontal boundary pushing into the region from NW with some widely scattered shower/isolated storm activity during afternoon/evening hours, which could interact with local sea breezes, but the ECMWF model remains too dry with this feature for much in the way of measurable rainfall so will continue ongoing "silent" forecast with PoPs of 10-15%. Best chances for any rainfall will likely across across inland SE GA. Ahead of this feature, Max temps will push into the upper 80s/near 90 over inland areas with 80-85 temps along the Atlantic Coast.
Wednesday through Saturday...With weak high pressure ridge lingering in the region through the end of the week and approaching frontal boundary from the Northwest, expect mainly diurnal sea breezes to slowly push inland each day, but any significant moisture remains limited and rainfall chances remain on the low end in the 10-20% range, but cannot be ruled out on any day along the sea breeze, while longer range models are suggesting that better rainfall chances will exist by next weekend as possible stronger frontal boundary pushes closer to the region.
While rainfall forecast remains low to moderate, models are suggesting above normal temps through this period with a moderate to high confidence of daily highs around 90 degrees over inland areas and in the lower/middle 80s closer to the Atlantic Coast.

Issued at 151 PM EDT Sat Apr 27 2024
Strong high pressure to the north northeast near the Mid-Atlantic coast will sink southward down the eastern seaboard through this evening with breezy easterly winds as a coastal trough over the northeast Florida waters tightens the local pressure gradient and Small Craft Advisory conditions the northeast Florida nearshore waters and all of the offshore waters. Slightly less winds and seas will bring Small Craft exercise caution conditions to the Georgia nearshore waters. Isolated showers will shift westward with the trough over the waters through this early evening. The high will slowly weaken overnight as it shifts southward near the North Carolina Outer Banks with winds diminishing near shore.
Small Craft Advisory conditions will persist offshore through Sunday morning. Winds and seas will further subside late Sunday into Sunday night as weaker high pressure anchors off the southeastern seaboard early next week, followed by prevailing winds shifting to southerly towards midweek.
Rip Currents: High Risk of Rip currents at all area beaches today.
A high risk is expected at all area beaches again on Sunday.
HYDROLOGY
Issued at 151 PM EDT Sat Apr 27 2024
Moderate Flooding continues over portions of the lowers Santa Fe River near Three Rivers Estates, but should lower into minor flooding by late Sunday, then remaining in minor flood through next week.
