The high pressure ridge moves well to the east by Monday. This along with the approach of a weak cold front will yield a more southerly flow over the waters Monday and Tuesday.

Area Forecast Discussion National Weather Service Jacksonville FL 824 PM EDT Thu May 2 2024

New UPDATE, AVIATION

UPDATE
Issued at 820 PM EDT Thu May 2 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

Enhanced deep moisture, with PWATS near 1.4 inches, located over the western zones of the forecast area and good convergence combined with MLCAPE of about 1000 J/kg continue to produce scattered, generally weak convection. Heavy rain and gusty winds are the main impacts.
Activity is generally centered near or west of I-75 corridor as of 8 pm. Looks like activity should mostly be dissipated by midnight.
Continued to advertise patchy to areas of fog tonight but may trend toward more coverage and lower visibility in the fog based on the guidance that is currently available. Will update our briefing to show this with the best chances of fog over the eastern half of the forecast area.

NEAR TERM
Issued at 208 PM EDT Thu May 2 2024

Still anticipating development of a few showers, isolated t-storms, with west-coast sea breeze in NW FL peninsula late this afternoon...
otherwise clear to partly cloudy skies expected. Continued mention of patchy fog toward dawn. Current low temperature forecast Tonight looks good...with mid 60s inland and around 70 coast.

SHORT TERM
(Friday through Saturday night)
Issued at 208 PM EDT Thu May 2 2024

Low level high pressure ridging will remain stubborn for Friday, which will overall tend to limit convective coverage despite a consistent sea breeze influence and adequate layer moisture.
Though still will expect isolated to widely scattered showers and a few t'storms Friday, mainly around the I-95 corridor similar to today. Convection should wean after sunset, with the potential for some overnight and morning fog once again into Saturday Morning given the pattern in place. Saturday, a rather slow moving mid level shortwave will slide across the general area in the zonal flow aloft, which will result in higher chances of daytime convection compared to Friday. Expecting the highest coverage to be over more inland southeast GA and the Suwannee River area, dropping off further east and southeast as the sea breeze boundary penetrates further inland. Not expecting a severe threat given the flow regime aloft, though a few strong storms cannot be ruled out with MLCAPE near or slightly above 1000 J/kg.

Temperatures will be very warm once again Friday, especially inland with the onshore flow quickly affecting areas approaching the coast. Upper 80s to around 90 inland, with low to mid 80s approaching the coast east of I-95. With the higher coverage of showers and t'storms Saturday, highs will be overall lower - in the mid to upper 80s inland and low 80s at the coast.

LONG TERM
(Sunday through next Thursday)
Issued at 208 PM EDT Thu May 2 2024

Generally onshore flow with surface high pressure sitting well offshore in the Atlantic should continue overall diurnal convection chances for the end of the weekend, and likely into the start of next week. Guidance also continues to move a weak impulse across the general area around Monday to Tuesday, though confidence is still lower than usual as the placement and magnitude of the shortwave remains in question. High pressure ridging builds further westward into the Gulf of Mexico by the middle of next week as a high pressure ridge also builds aloft.
Therefore, an overall increasingly dry and warmer trend should coincide for this period, possibly approaching record highs by Wednesday and/or Thursday.

AVIATION
(00Z TAFS)
Issued at 820 PM EDT Thu May 2 2024

Some low threat of -TSRA at GNV over the next 1-2 hours but otherwise mostly clear into late tonight. Rather good chances of fog expected at JAX, VQQ, and CRG tonight and have trended lower with the vsby.
Lower confidence for vsby problems at SSI but indicated MVFR possible.
Next TAF update will be able to fine tune forecast. After the fog dissipates by 13z-14z Friday, VFR clouds expected and precip chances are too small to add any VCSH or VCTS at this time.

MARINE
Issued at 208 PM EDT Thu May 2 2024

Stationary high pressure centered well north of the waters will maintain a southeast flow over the waters through the upcoming weekend. Afternoon and evening wind surges are expected today and Friday due to the sea breeze. The high moves eastward Monday. This along with the approach of a weak cold front will yield a more southerly flow over the waters Monday.

Rip Currents: Moderate risk through Friday.
