AMZ400 Synopsis For Altamaha Sound Ga To Flagler Beach Fl Out To 60 Nm- 122 Pm Est Thu Dec 7 2023
Synopsis..
high pressure will shift over the waters this afternoon and evening and progress eastward beyond the gulf stream this weekend as a cold front approaches from the northwest. The cold front will pass across the coastal waters Sunday night into Monday and elevate winds and seas to small craft advisory levels, particularly offshore. Numerous showers and scattered Thunderstorms will be associated with this frontal passage. Behind the front, an initial area of high pressure will build from west and then to the north through Tuesday resulting in breezy to windy onshore flow through the latter half of next week.

Gulf stream..

NEAR TERM
(Through Friday)
Issued at 146 PM EST Thu Dec 7 2023

For the latest NE FL and SE GA Daily Key Messages please visit: https:// www.weather.gov/media/jax/briefings/nws-jax-briefing.pdf

Tranquil weather conditions are expected tonight through Friday as high pressure continues to migrate overhead and then push east into the Atlantic through Friday. As it does so, predominant flow will shift southerly and prompt a warming trend that will carry into the weekend. Lows tonight will be warmer tonight as an impulse lifts overhead bringing a blanket of mid and high clouds; readings will be in the low/mid 40s inland and in the low 50s closer to the coast, which will not support frost development.

SHORT TERM
(Saturday through Saturday night)
Issued at 146 PM EST Thu Dec 7 2023

By Saturday, southerly winds will warm up temperatures into the mid to upper 70s area-wide, with some locations seeing high temps about 10 degrees above climo. By Saturday evening showers ahead of a frontal passage moving southeastward will approach inland southeast Georgia.

LONG TERM
(Sunday through next Thursday)
Issued at 146 PM EST Thu Dec 7 2023

Active weather expected Sunday as a cold front approaches from the northwest. Numerous showers forecast across NE FL and SE GA, with a chance for isolated thunderstorms as well. Some of which have the potential to be strong, but chances remain low at this time.
Fairly good agreement on timing among models for this frontal passage, with the onset of precip beginning late Saturday night into early Sunday morning, filling in southeastward throughout the day. Elevated southwesterly flow off the Gulf of Mexico ahead of the frontal passage will allow for ample moisture, with PWATs rising above 1.5 inches. The heaviest rainfall and greatest thunderstorm risk timing will be early afternoon to evening on Sunday.

Following the frontal passage Sunday evening, dry air will infiltrate in across the region, and temperatures will bounce back to below average. Sunday night lows will be in the upper 30s across inland SE GA, with lower to mid 40s along the coast and inland NE FL as gusty winds shift to northwesterly. Chilly high temperatures Monday as cold air advection continues, temperatures will stay below 60 degrees for most of NE FL and SE GA. As winds calm slightly, low temperatures fall to just above freezing for inland SE GA, frost at this time is not expected due to winds remaining at 5-10 mph overnight. Temperatures will gradually warm up mid- week to near normal as high pressure builds to our north, allowing for breezy onshore winds and potential for isolated showers on Wednesday moving inland off the Atlantic.

AVIATION
(18Z TAFS)
Issued at 1247 PM EST Thu Dec 7 2023

Surface high pressure migrating through the region will keep winds light and variable through the period. An uptick in moisture levels will allow some patchy MVFR-, possibly IFR-, grade restrictions at NE FL terminals late tonight through around sunrise Friday. On Friday a weak sea breeze will develop late in the period with speeds under 10 knots. A scattered field of afternoon cumulus around 4-5 kft will develop Friday.

MARINE
Issued at 146 PM EST Thu Dec 7 2023

High pressure will shift over the waters this afternoon and evening and progress eastward beyond the Gulf Stream this weekend as a cold front approaches from the northwest. The cold front will pass across the coastal waters Sunday night into Monday and elevate winds and seas to Small Craft Advisory levels, particularly offshore. Numerous showers and scattered thunderstorms will be associated with this frontal passage. Behind the front, an initial area of high pressure will build from west and then to the north through Tuesday resulting in breezy to windy onshore flow through the latter half of next week.

Rip Currents: Moderate risk of rip currents will continue through Friday at NE FL beaches. A lower risk is expected at SE GA beaches through the end of the week. Increasing risk is expected this weekend with a passing cold front.

FIRE WEATHER
Issued at 146 PM EST Thu Dec 7 2023

Moisture will return to NE FL and SE GA beginning Friday as winds shift southerly, rising minRH values to above 50% through the weekend.
Dispersion will be fair to low Friday and Saturday inland, with critically low values along the immediate Atlantic coast, below 20 units on Friday.
Rain chances will increase over the weekend, especially by Sunday when a cold front moves into the area accompanied by numerous to widespread showers and a slight chance of thunderstorms. The front will sweep east of the area Sunday night.
