New UPDATE

UPDATE
Issued at 1037 AM EDT Tue May 14 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

A broken line of showers and storms went through SE GA and NE FL this morning, with residual convection along SR16 this late morning. This convection will continue to push eastward. Some of the residual convection may produce winds to 40 mph, before pushing offshore. A second batch of convection extends from Marion County into the northeast Gulf of Mexico. The line of showers and storms over the NE GOM will advect into the Nature Coast and push inland with strongest storms for JAX AOR this afternoon across north central FL will bulk of stronger to severe storms moving into the I-4 corridor this afternoon. We will be closely monitoring the storms that track across north central FL for best moisture convergence will reside over Marion, Alachua, Putnam and Flagler Counties this afternoon. Otherwise convection with this particular round will be limited across the rest of northeast Florida and SE GA.

Another disturbance will bring in another round of showers and storms across the region overnight. Plenty of elevated instability will be in place, as the nearly stalled front northwest of the area also starts to make some progress southeastward. Needless to say, a strong to severe threat will be present overnight tonight, as convection moves towards the area likely in the form of a squall line. In addition, heavy rain and localized flooding has the highest potential during the pre-dawn hours into Wednesday morning, primarily south of I-10. Stay tuned for more developments on that throughout the day.

NEAR TERM
Issued at 303 AM EDT Tue May 14 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

A rather complex and tricky forecast continues for most of today and into tonight, as several shortwave impulses ride along a nearly stalled boundary across the area. The first round will be during the morning hours today, as showers and storms currently over the western FL panhandle move their way across the region.
With the morning timing of the precip, instability will be rather limited. However, still expecting enough buoyancy in place aloft for embedded thunderstorms within the approaching line of showers and trailing stratiform precip. Given the dynamical support with the shortwave and modest lapse rates aloft, there will be a chance for strong to severe storms as well, with gusty winds and hail being the main hazards. The best chance for this looks to be along and south of I-10 where the most instability will be in place. In fact, timing may also help an uptick of later morning surface heating in areas furthest south and east, and therefore an uptick in surface based CAPE.

The first batch clears the area around late morning, with the amount of potential convective coverage uncertain during the afternoon/evening due to the morning showers and storms. It will take some time for the atmosphere to "reset" behind the morning convection, though still expecting enough daytime heating for some showers and thunderstorms to pop up by the evening hours. Temps climb into the 80s to low 90s south and dew points will be near and over 70 area wide, and with the boundary lingering with modest dynamics aloft, there will be potential for strong to severe cells once again. Similar to this morning, gusty winds and hail will be the main threats, though an isolated tornado cannot be ruled out.

Convection should clear out approaching midnight tonight before, you guessed it - another wave of energy aloft moves another round of showers and storms across the region overnight. Plenty of elevated instability will remain overnight, as the nearly stalled front northwest of the area also starts to make some progress southeastward. Needless to say, a strong to severe threat will persist through overnight tonight, as convection moves towards the area likely in the form of a squall line. Stay tuned for more developments on that throughout today. Lows tonight will be mild once again, similar to those of this morning (upper 60s and low 70s).

SHORT TERM
(Wednesday through Thursday night)
Issued at 303 AM EDT Tue May 14 2024

Wednesday...Ahead of approaching frontal boundary still expect ongoing morning numerous to widespread showers and storms across NE FL with heavy rainfall the main threat, although some isolated strong to severe storms with damaging winds still possible. Models still on track with pushing this boundary slowly southward through NE FL through the afternoon with skies becoming Mostly Sunny across SE GA as rainfall ends there during the morning hours with rainfall ending across NE FL by the late afternoon/early evening hours. Localized flooding will be the main impact across inland NE FL through the day as 3 day storm total rainfall amounts in some locations likely approach 4-6 inches, especially across Hamilton/Suwannee/Columbia/Gilchrist counties and a flood watch may be required at some point during this event. Breezy West- Southwest flow at 15-20G30 mph expected as diurnal heating mixes down leftover winds behind the trailing frontal passage. Likely sunshine breaking out by the afternoon hours should push Max temps into the mid/upper 80s for all areas.

Wednesday Night...Drier airmass overspreads the local area with dry conditions after sunset and skies becoming mostly clear and temps falling into the 60s area-wide behind the frontal passage.

Thursday...Lingering 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.

LONG TERM
(Friday through Monday)
Issued at 303 AM EDT Tue May 14 2024

Friday...Long range models still differ on timing of next frontal boundary with the latest GFS run keeping the local area dry and hot, while the ECMWF remains faster with pushing scattered afternoon/evening storms into the region. So for now the model blends have kept PoPs in the 30-50% range. Southwest steering flow will push Max temps above normal and into the lower 90s inland and upper 80s along the Atlantic Coast along with Heat Indices pushing close to 100F.

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...Lots of long range model uncertainty as some models push drier air into the region, while some stall the frontal boundary in the vicinity so for now the model blends are just placing normal diurnal scattered convection due to local sea breeze activity as above normal temps continue.

AVIATION
(12Z TAFS)
Issued at 806 AM EDT Tue May 14 2024

First line of convection extends from JAX thru GNV across NE FL and another cluster is west of KSSI this morning. This line and cluster will move eastward and push offshore by 14z. Some wind gusts of 30 to 35 mph with some stronger storms is possible with cigs and vsby briefly lowering to IFR with downpours of rain.
from 14z to 20z we should see a brief respite of convection.
Between 20z and 22z, we may a second chance of showers and storms recommence with TEMPOS of thunderstorms through 02z. Again brief lowering of vsbys and cigs associated with heavy downpours during this period. Models show another respite with this wave of showers and storms from 02z through 06z, with perhaps a third round of convection commencing during the overnight hours.

MARINE
Issued at 303 AM EDT Tue May 14 2024

Elevated south-southeasterly winds across the local waters will begin to subside through today, with Small Craft ADvisory conditions lowering through this morning. Rain and embedded storms will pass over the waters this morning, then again this afternoon/evening and through the overnight hours while a warm front slowly lifts northeastward into the waters by daybreak. A wave of strong to severe storms will develop and move eastward into the waters during the late morning hours today, and be capable of considerable thunderstorm wind gusts, hail, and waterspouts. Winds will trend lighter and offshore behind the warm front Tuesday morning. This will be followed by a slow moving cold front that will pass into the waters on Wednesday. Conditions begin to improve Thursday as an area of weak high pressure consolidates to the east.

Rip Currents: Rip current risk remains moderate through tomorrow with the enhanced flow and stalled boundary over the area.
