AMZ400 Synopsis For Altamaha Sound Ga To Flagler Beach Fl Out To 60 Nm- 158 Am Edt Wed May 15 2024

Synopsis -
widespread showers and the potential for strong to severe storms are expected over our local waters through the morning hours. Stronger storms may produce damaging wind gusts, hail and even waterspouts. Storms and showers will shift southeastward late Wednesday morning as a cold frontal boundary shifts southward through the waters.conditions will improve from north to south Wednesday afternoon and evening, with breezy westerly winds expected outside of Thunderstorms that will gradually subside by Thursday afternoon as weak high pressure moves over the southeastern states. Winds will turn southerly on Friday ahead of the next frontal boundary that will impact our area this weekend. Showers and Thunderstorms will likely impact our local waters from Saturday afternoon through Sunday morning, with a few strong storms possible. Winds will then shift to northwesterly by Sunday afternoon and night as this front pushes offshore.

NEAR TERM
Issued at 201 AM EDT Wed May 15 2024

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

Shortwave energy crosses southern and central parts of the area tonight, and combined with plentiful moisture and elevated instability will develop showers and thunderstorms overnight, especially from about I-10 southward. In addition, a cold front is approaching western GA as of the 03Z WPC surface analysis, which will continue to shift southeastward throughout the night and today. Effective/0-6km shear is definitely sufficient, but the more significant element is the amount of available energy, especially aloft, where forecast soundings indicate near or about 2000 J/kg of MUCAPE or higher, with noticeable amounts within the hail growth zone. Therefore, expecting hail to be the primary threat with any stronger updrafts, though shear and kinematics certainly would warrant strong wind potential of 40-60mph. An isolated tornado cannot be ruled out as well, though this potential looks marginal.

Overnight convection will be persistent into the late morning to early afternoon hours while slowly drifting south with the approaching front and associated dynamics aloft with the parent upper trough. Expecting a similar threat to play out for southern counties in northeast FL for the late morning to afternoon period, as vertical profiles will remain similar (high CAPE and sufficient shear). It is certainly possible for a couple of showers and isolated thunderstorms to pop up immediately ahead of the approaching front though lagging behind overnight activity as the front progresses southeastward (as far north as north of I-10), in which some high res solutions are suggesting. Though the severe threat should drop off quite a bit from south of north throughout the afternoon as a lot of drier air works its way in aloft. Southwest to westerly winds will also be quite breezy today, though below wind advisory criteria (10-20 mph and gusts in the upper 20s to 30s). Temps will be not as traditional today due to the frontal boundary and morning convection - generally in the mid to upper 80s south of I-10, with some areas approaching 90 possible over a stretch of southeast GA.

The front should settle sufficiently south of the region by tonight as some drier air near the surface and especially aloft fills in. Overall decreasing clouds and lows in the 60s inland, and near 70 near the St. Johns River and coast.

SHORT TERM
(Thursday through Friday night)
Issued at 201 AM EDT Wed May 15 2024

Thursday...Dry airmass in place between weather systems will continue mainly dry conditions under mostly sunny skies with above normal temps reaching into the upper 80s/lower 90s over inland areas with West-Northwest winds at 10-15 mph and East Coast sea breeze remains pinned closer to the Atlantic Coast.

Thursday Night...High clouds slowly increase ahead of next weather system with light SW winds at the surface. Low temps in the 60s inland and lower 70s along the Atlantic Coast. Dry conditions will continue.

Friday...Moisture levels will continue to slowly increase ahead of the weekend weather system in the low level SW steering flow and this may be just enough to trigger afternoon/evening shower/storm activity along the sea breezes as they move further inland and meet along the US 301 corridor later in the day. Temps continue well above normal in the upper 80s SE GA and lower 90s NE FL with slightly lower values along the Atlantic Coastal areas.

Friday Night...Still some significant model diffs as the faster ECMWF bring in pre-frontal showers/storms in this period while the latest GFS/NAM keeping activity to the NW of the region with mostly dry and humid conditions, so for now have been keeping with model blends which keep scattered showers/isolated storms going through the night with above normal low temps in the lower/middle 70s.

LONG TERM
(Saturday through Tuesday)
Issued at 201 AM EDT Wed May 15 2024

Saturday...Next frontal boundary pushes into the region with a return to heavy rainfall and isolated strong to severe storm potential area-wide and rainfall chances already in the 60-80% range. Above normal temps will continue ahead of the frontal boundary with upper 80s SE GA and still into the lower 90s for NE FL with Heat Indices still close to 100F across NE FL.

Sunday/Monday/Tuesday...Models coming into better agreement that in the wake of departing storm system a drier airmass will push into the region on Northwest flow with limited rainfall chances and temps still slightly above normal but not as hot with Max temps in the 85-90 range and lows 65-70. Some limited moisture return by Monday and Tuesday may lead to widely scattered afternoon/evening showers and storms along sea breeze boundaries but overall below normal rainfall chances are expected.

AVIATION
(06Z TAFS)
Issued at 124 AM EDT Wed May 15 2024

SHRA and TSRA are developing at this hour, and are expected to increase in coverage for most through the next several hours. TSRA is expected for at least all FL terminals, though have continued to include at SSI as well. Recent trends in guidance have been for a southern shift in TSRA coverage, though confidence is too low to remove SSI from TSRA consideration. GNV and SGJ are will have the highest chances for TSRA as well as strong to severe TSRA, which will last into the late morning to afternoon hours. Some storms this morning could be capable of large hail and gusts of 35-55 knots. Heavy rainfall and lower ceilings will also cause periods of MVFR and isolated IFR, as indicated in TEMP groups. TSRA and especially strong/severe TSRA threat subsides from north to south at terminals this afternoon and into the evening, with only some isolated SHRA lingering before sunset. VFR is expected to return for the final 3 to 6 hours of the forecast period.

MARINE
Issued at 201 AM EDT Wed May 15 2024

Widespread showers and the potential for strong to severe storms are expected over our local waters through the morning hours.
Stronger storms may produce damaging wind gusts, hail and even waterspouts. Storms and showers will shift southeastward late Wednesday morning as a cold frontal boundary shifts southward through the waters.Conditions will improve from north to south Wednesday afternoon and evening, with breezy westerly winds expected outside of thunderstorms that will gradually subside by Thursday afternoon as weak high pressure moves over the southeastern states. Winds will turn southerly on Friday ahead of the next frontal boundary that will impact our area this weekend.
Showers and thunderstorms will likely impact our local waters from Saturday afternoon through Sunday morning, with a few strong storms possible. Winds will then shift to northwesterly by Sunday afternoon and night as this front pushes offshore.

Rip Currents: Moderate rip current risk continues today due to unsettled weather, dropping to low Thursday with generally weakening offshore flow.
