AMZ400 Synopsis For Altamaha Sound Ga To Flagler Beach Fl Out To 60 Nm- 720 Pm Est Sun Dec 10 2023
Synopsis..
a strong cold front will push across the waters around midnight bringing an abrupt shift and increase in winds. A brief period of gale force gusts will be possible with the initial wind shift and an hour or so afterward before decreasing to small craft advisory level conditions. High pressure will build from the west allowing winds to gradually subside as they shift northerly through Monday. That high pressure will build to the north and strengthen through the week, which will yield a prolonged period of strong northeast winds through the end of the week and into next weekend.

Gulf stream..
the approximate location of the west wall of the gulf stream as of dec 09, 2023 at 1200 utc...
50 nautical miles east of flagler beach. 53 nautical miles east of saint augustine beach. 61 nautical miles east of jacksonville beach. 78 nautical miles east of st simons island.

AVIATION
(06Z TAFS)
Issued at 112 AM EST Mon Dec 11 2023

IFR ceilings will prevail at the regional terminals through around 08Z, with light showers lingering at CRG through 07Z and at SGJ through around 08Z. Ceilings will then quickly lift to MVFR between 08Z-09Z, with VFR conditions then expected to prevail at the regional terminals by 10Z. West-northwesterly surface winds will remain sustained around 10 knots overnight, with winds shifting to northwesterly and increasing to 10-15 knots by 13Z.
Surface winds will then shift to northerly at GNV, SGJ, and SSI towards 20Z and towards 00Z elsewhere. Winds are expected to subside to the 5-10 knot range towards sunset on Monday evening.

UPDATE
Issued at 635 PM EST Sun Dec 10 2023

The threat of severe weather has ended and the earlier tornado watch was cancelled. Pockets of moderate to heavy rain continue to push east and a few embedded and elevated storms are still possible south of Jacksonville along the NE FL coast for the next half hour or so.

Upstream, the cold front is progressing eastward across the FL panhandle and will reach our area late this evening then push offshore into the Atlantic by midnight. A strong initial bout of wind is expected with the frontal passage, with gusts in the 35-40 mph range. Though isolated gusts of 40+ mph will be possible, mainly at the immediate beaches, it will be so brief that a Wind Advisory is not necessary. A few more showers capable of moderate rain will also push through with the front as it passes.

Strong cold air advection will plummet temperatures overnight and low temps into the upper 30s from the Suwannee Valley northward across inland SE GA. Elsewhere, low to mid 40s are anticipated by sunrise Monday.

SHORT TERM
(Monday through Tuesday night)
Issued at 305 PM EST Sun Dec 10 2023

Building high pressure from the west will lead to dry conditions for the area during the start of the week. Onshore flow will lead to the advection of moisture over coastal locations resulting in the possibility of a few coastal showers. Daytime highs will mainly be in the upper 50s across the area with north central Florida reaching the lower 60s. Temperatures will hover just above freezing during the overnight hours into Tuesday. Lows for most of northeast Florida will dip to the low/mid 40s. Lows over the the Suwannee Valley Region in northeast Florida and northward towards southeast Georgia will see temperatures dip to the mid 30s. Come Tuesday, the dry conditions will continue with the addition of an increase in cloud cover as the day progresses. A bit warmer temperatures on Tuesday as Highs will be in the 60s with warmer temperatures over north central Florida.

LONG TERM
(Wednesday through next Sunday)
Issued at 305 PM EST Sun Dec 10 2023

The dry conditions are expected to continue at the start of the forecast period as high pressure remains to the north of the area. Precipitation chances increase on Friday, with the counties in north central Florida with the best chances of rain as moisture moves northward from central Florida . Precipitation chances will currently stay in the 30% to 40% range as guidance remain uncertain in the magnitude and the northward extent of instability and deep moisture. Daytime Highs will remain in the 60s during this period, with north central Florida counties getting into the lower 70s. Overnight Lows in southeast Georgia will be in the mid/upper 40s, whereas northeast Florida will have lows in the mid/upper 50s.

MARINE
Issued at 305 PM EST Sun Dec 10 2023

A strong cold front will cross the local waters this evening with solid Small Craft Advisory conditions in the Southwest flow ahead of the squall line of strong to isolated severe thunderstorms that will precede this front with stronger storms being capable of producing damaging wind gusts and waterspouts through early this evening. Outside of thunderstorm activity, westerly winds will increase towards sunset for the near shore waters, with winds then shifting to northwesterly and occasionally gusting to Gale Force after midnight both near shore and offshore, but will hold off on Gale Warning as most of the peak wind gusts over 35 knots will occur with pre-frontal convection.

High pressure will then build over the southeastern states in the wake of this cold frontal passage on Monday morning, allowing for gradually diminishing northerly winds and subsiding seas. This high pressure center will migrate northeastward and will strengthen over the coastal Carolinas on Tuesday, resulting in an extended period of strong northeasterly winds and steadily building seas that will persist into next weekend with Small Craft Advisory headlines re-developing. Coastal troughing developing over our near shore waters will likely develop showers by mid to late week that may persist into next weekend.

Rip Currents/Surf: Offshore flow on Monday will lead to Low Risk of Rip Currents, with a return to Moderate Risk of Rip currents on Tuesday as onshore flow develops, then High Risk likely from Wednesday well into next weekend as onshore flow increases and surf builds. Surf around 2 ft Monday will build to 2-4 ft on Tuesday, and 3-6 ft Wednesday, then into the 5-8 ft range by Thursday with High Surf Advisory headlines likely through the end of the week at least.
