UPDATE

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

Adjusted PoPs slightly for this afternoon, main area for any shower/storm development still expected along the I-95 corridor in NE FL as the sea breeze moves inland. Temperatures this afternoon will get into the lower 90s for inland locations with cooler temperatures along the coast in the upper 80s.

NEAR TERM
Issued at 309 AM EDT Tue May 7 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

High pressure ridging from out of the Gulf will strengthen over the region today resulting in inhibited convection with potential showers and storms forming in the afternoon hours primarily along the diurnal sea breeze convergence followed by dry weather conditions through tonight and on into Wednesday morning. High temperatures this afternoon will rise into the 90s over inland areas and into the upper 80s along the coast. Overnight low temperatures will drop down into the mid to upper 60s over inland areas and into the lower 70s for areas near the shoreline and along the St Johns River. Patchy early morning fog developments, potentially forming over areas west of the I-75 corridor will dissipate with the sunrise.

SHORT TERM
(Wednesday through Thursday night)
Issued at 309 AM EDT Tue May 7 2024

The main story through midweek will be the abnormally hot afternoons as stout upper ridging builds overhead and increasing offshore winds pins the cooling sea breeze over the coastal waters.

Very limited rain chances by Wednesday as a batch of dry air drains precipitable water and subsidence capping builds. There is a chance that an isolated late-afternoon shower or two develops along the pinned sea breeze which may push right into the I-95 corridor but unlikely any further. Otherwise, mostly sunny skies and temps pushing toward the mid 90s areawide. These hot readings will even occur at the coast with a the sea breeze push being delayed until around the time of peak heating.

Ridging aloft will flatten slightly by Thursday but gradients tighten as a cold front to the northwest makes inroads into the Southeast. Strengthening southwesterly winds, with gusts around 20- 25 mph, will keep the sea breeze offshore and allow deeper mixing (better heating) under mostly sunny skies. Daily record high temperatures will be threatened Wednesday and Thursday as Heat Index values climb to near triple digits. Being the first HOT days of the year, impacts on heat-sensitive (the young, elderly, and outdoor workers) groups will be possible.

LONG TERM
(Friday through Monday)
Issued at 309 AM EDT Tue May 7 2024

Based on the consistency in the medium range guidance and ensemble systems, the pattern appears to transition to a wetter pattern this weekend and into next week as a cold front slides southward into Florida. With the frontal passage timing details are still a bit murky, so confidence in specifics remains low. Will have to closely monitor what appears to be a nocturnal MCS trailing across the northern Gulf coast region and into southern GA Thursday night into Friday ahead of the front. The materialization and trajectory of that MCS will dictate the environment and threat of severe t'storms with the frontal passage on Friday. Mostly dry conditions are expected over the weekend as the front stays south but chances increase early next week as that old front lifts back to the north as a warm front. Temperatures trend downward and fall below normal through at least Monday before warming up once again.

High pressure ridge will gradually shift south and east through Thursday with breezy south winds expected at times. Offshore winds develop by Thursday night as a cold front approaches the region.
Evening southerly wind surges may lead to cautionary conditions for small craft each night until the cold front arrives by Friday night. Offshore winds will increase Friday ahead of a frontal passage. Brief period of strong northerly winds possible in the wake of the front Friday night into Saturday.

Rip Currents: Moderate risk for NE FL beaches today and Wednesday.

FIRE WEATHER
Issued at 309 AM EDT Tue May 7 2024

Isolated showers and perhaps a storm or two inspired by the sea breeze are possible this afternoon. After today, hotter and drier conditions prevail under a building ridge of high pressure Wednesday and Thursday before a late season cold front arrives Friday. Strengthening surface and transport winds from the southwest ahead of the front will build dispersion each day through Friday. High dispersions are expected areawide by Thursday and likely again Friday. A wetter pattern will kickoff with the frontal passage this weekend and should continue into next week.
