...STRONG THUNDERSTORMS POSSIBLE LATE THIS AFTERNOON WEST OF HIGHWAY 301...

NEAR TERM
Today and Tonight...

Fog development this morning will be fairly sparse and generally shallow, as elevated southerly flow maintains a somewhat mixed boundary layer. Otherwise, a few showers continue to stream across inland southeast GA early this AM as upper level diffluence enhances downstream from an approaching shortwave just to the west.

As that shortwave makes its way slowly eastward, the associated cooling aloft and moistening mid levels will offer a sufficient amount of diurnal instability this afternoon. With those ingredients in play along with the sea breezes, scattered to numerous showers are expected to develop during the mid and late afternoon hours, mainly across interior SE GA and inland NE FL west of Highway 301. Steep low level lapse rates will allow potentially strong outflow winds in the vicinity of pulsing storms. Outflow and sea breeze interaction may lead to a few strong storms this afternoon and evening. Given a fairly weak westerly steering flow, motion of storms today will be outflow driven with a tendency to slowly drift back toward the east coast as they weaken. In addition to a few strong gusts with the more robust convection, PWATs pushing toward the 90th percentile according to sounding climo will allow for localized heavy rain (which will be beneficial given the ongoing dry spell).

Convective debris clouds will drift eastward tonight as convection wanes with mostly quiet conditions through the overnight hours.
There will be another chance for at least patchy inland fog, particularly in locations that receive a decent amount of rain.

Temps today will be modulated by cloud cover and the onshore flow which should keep most of SE GA and coastal NE FL high temp readings in the low/mid 80s while the rest of NE FL warms into the upper 80s to near 90 this afternoon. Another mild night will follow the warm afternoon with lows in the mid/upper 60s except at the coast where onshore flow will keep lows from falling below 70F.

SHORT TERM
(Sunday through Monday night)

Pattern of diurnal convection will continue through Sunday and Monday as a series of mid level short waves pass over the region.
Shower and storm developments are expected to be largely scattered with developments becoming more numerous along the diurnal sea breeze boundaries and areas of convergence. High temperatures for this period will be in the upper 80s and lower 90s for inland areas and in the lower to mid 80s along the coastline.

LONG TERM
(Tuesday through Friday)

Predominantly dry weather through the rest of the week as high pressure ridging dominates the weather pattern. Sea breeze winds will be largely pinned to the coast by midweek as prevailing flow shifts to become more out of the southwest due to the positioning of the high pressure axis. Temperatures will rise into the mid 90s as the week progresses with temps potentially reaching record seasonal levels by the end of the period.



AVIATION
(06Z TAFS)
Issued at 128 AM EDT Sat May 4 2024

VFR conds continue with shallow, localized mist/fog developing through the remaining predawn hours at inland airfields (KGNV & KVQQ). Amid a more unstable airmass, sea breeze interaction and a passing disturbance will lead to scattered thunderstorms mainly along and east of Highway 301 during the late afternoon (after 20z).
Convective impacts are most likely at KGNV; however, outflow may impact terminals with vicinity showers/storms. As storms weaken this evening, the remnant showers will drift eastward and possibly pass across coastal terminals in NE FL toward the end of the current TAF period. Outside of outflow influence, predominant winds will be east to east-southeasterly around 7-12 knots then trending lighter after 00z.

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 early this 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.
