New UPDATE

UPDATE
Issued at 927 AM EDT Fri May 3 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

Morning fog has dissipated and the forecast is generally on track.
Just minor tweaks to POPs for later today and tonight, with some showers and a few thunderstorms expected in similar areas as seen yesterday as the sea breeze penetrates inland. Activity is expected to linger over the Suwannee River Valley area and generally spread into interior GA overnight as a shortwave impulse approaches the area. Only marginal elevated instability and weak flow aloft should essentially curtail any strong or severe potential.

NEAR TERM
Issued at 323 AM EDT Fri May 3 2024

Over the next couple of hours the main concern will be localized fog. Dense fog cannot be entirely ruled out but have left it out of the forecast at the moment with generally low confidence (< 10% chance) of visibility lowering less than 1/4 mile. Any fog that does occur should lift and disperse by 9 AM or earlier.

Stagnant pattern remains in place again today, featuring a stubborn surface high and supporting ridging aloft. Overall the low level pattern will stay consistent but an upper shortwave aloft will shove ridging aloft eastward late this evening and overnight. Strong subsidence and dry air should cap much of the convective attempts along the Atlantic sea breeze this afternoon. Enhanced moisture entering from the west in combination with an Atlantic/Gulf sea breeze interaction may spark isolated to widely scattered storms well inland, near and likely west of the I-75 corridor.
Instability is still on the marginal side (only progged to be around 800-1200 J/kg), thus updrafts should be fairly weak in nature and severe weather is unlikely.

Tonight, the aforementioned shortwave will slowly propagate across the region resulting in increasing instability with a couple degrees of cooling aloft. This should be supportive of showers overnight mainly north of I-10 and a few elevated t-storms are also feasible through the early morning hours Saturday.

Under influence of ridging aloft another seasonably warm day is on tap this afternoon with inland locations making another push toward 90F while coastal spots are cooled by the onshore flow with readings registering in the mid/upper 80s. Following the warm afternoon, temps will be mild, reading in the mid/upper 60s.

SHORT TERM
(Saturday through Sunday night)

Showers and storms are expected this weekend as a series of short waves pass over the region with sea-breeze-driven storm developments becoming more widespread with diurnal heating. Mild easterly-southeasterly winds will persist through the period with the Atlantic afternoon sea breeze winds pushing inland. High temperatures for the weekend will reach into the mid to upper 80s with overnight low temperatures dropping down into the mid 60s over inland areas and in the upper 60s and lower 70s for areas along the coast and adjacent to the St Johns River. Patchy fog potential will exist each morning, especially in localized areas where heavy rain occurs with preceding afternoon convection.

LONG TERM
(Monday through Thursday)
Issued at 323 AM EDT Fri May 3 2024

Shortwave impulses continue to lift across the region through Monday with shower and storm developments becoming more inhibited as the week progresses due to the increased influence of upper ridging and associated subsidence extending over Florida and Georgia. Amid the stout upper ridge, winds turn offshore and enhance mixing which will boost high temperatures toward record levels as the week progresses; readings are forecast to be in the mid 90s.

AVIATION
(12Z TAFS)
Issued at 715 AM EDT Fri May 3 2024

Brief LIFR CIGS/VSBYS this morning at SSI/CRG/VQQ will become VFR by 13Z, then sea breeze from the East Coast will push inland through the day with SCT Cu field, but likely not enough moisture to support any rain chances higher than 20% at the TAF sites at this time, but will continue to monitor. Band of high clouds will overspread the TAF sites this afternoon above the local Cu field and will continue through tonight with winds becoming light after sunset. Have placed the usual MVFR fog at VQQ after 07Z.

MARINE

High pressure will remain anchored northeast of the local waters through the weekend. Afternoon sea breeze development will continue each afternoon for the next several days as high pressure repositions further south, shifting winds toward a southeasterly direction next week. Winds should trend offshore toward the end of next week as a cold front approaches from the northwest.

Rip Currents: Risk will only increase to a low-end moderate level as the Atlantic sea breeze develops during the afternoon hours.
Otherwise, low surf and light wind will keep risk low.
