...ISOLATED STRONG/SEVERE STORMS POSSIBLE SOUTHEAST GA LATE WEDNESDAY...
NEAR TERM
(Through Tonight)
Issued at 220 PM EDT Tue Apr 22 2025
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 weak surface ridge axis will be across the north FL peninsula and flow aloft remains southwesterly. A shortwave will approach the area through tonight but airmass and moisture are generally not supportive of mentioning precip. However, a shower or two (about 10 percent chances) will be possible over southeast GA this evening. Highs today will reach into the mid and upper 80s, with lower 80s at the coast. Meanwhile, scattered cumulus will dissipate this evening but high clouds are likely to continue tonight. Some patchy fog is forecast late tonight for inland areas. Lows tonight in the 60s expected.
SHORT TERM
(Wednesday through Thursday night)
Issued at 220 PM EDT Tue Apr 22 2025
Hot temperatures continue Wednesday and Thursday, with inland highs reaching the mid 80s to lower 90s, with the Atlantic sea breeze keeping the coast a few degrees cooler both days. Low temperatures will be mild in the 60s, with near 70 degrees along the coast and St. Johns river basin.
Precipitation chances will be mainly north of I-10 both Wednesday and Thursday as a front remains stalled north of the forecast area. With solid daytime heating and a sea breeze formation, isolated thunderstorms are likely in the afternoons and evenings.
Wednesday looks like a better opportunity for stronger to isolated severe storm formation, with CAMs highlighting southeast Georgia, as well as north central Florida (west of the St. Johns river basin) through the evening. Strong winds and hail will be the primary threats with any strong or isolated severe thunderstorm development due to relatively steep mid level lapse rates.
LONG TERM
(Friday through next Tuesday)
Issued at 220 PM EDT Tue Apr 22 2025
Above average temperatures will continue through the weekend, again with the Atlantic sea breeze keeping the coast a little bit cooler than inland locations. Showers and isolated thunderstorms will be possible over southeast Georgia on Friday and Saturday as a cold front approaches. The front will move through the area on Sunday, bringing rain chances of 20-30% across NE FL and SE GA along with isolated thunderstorms. Behind the front, temperatures will return to near normal for the start of next week.
AVIATION
(18Z TAFS)
Issued at 130 PM EDT Tue Apr 22 2025
The TAF period will feature VFR conditions through the period except for MVFR fog restrictions at VQQ by 07z through 13Z.
Otherwise, mainly SCT cumulus at or above 4 kft through this evening with south to southeast winds of 5-12 kt, strongest from the southeast for the coastal TAFs. Winds become light south tonight and increase from the south-southeast near 10 kt on Wednesday.
MARINE
Issued at 220 PM EDT Tue Apr 22 2025
Little change in the ongoing marine forecast with southeast to south winds up to 10-15 kt and seas of about 2-4 ft much of the week. There is a slight increase in the combined sea heights by Thu night into Friday, but for most part seas stay in the 2-4 ft/2-3 ft range with dominant periods of 5 to 9 seconds. A further increase in winds and seas will be possible over the weekend as a backdoor front moves into the region.
Rip Currents: A moderate risk of rip currents is in effect for Northeast Florida and Southeast Georgia beaches rest of today and Wednesday due to the onshore winds and surf 2-3 feet. Stronger rip currents can form near piers and jetties. Always swim near a lifeguard.
