New UPDATE, AVIATION

UPDATE
Issued at 835 PM EDT Mon Jul 14 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

Lowered temps heading into the evening hours as showers and storms helped to bring temps into the lower 80s and upper 70s sooner than earlier forecast. Otherwise forecast remains the same. Lingering showers and storms will continue to move towards west-southwest thanks to the northeasterly flow. Winds will become near calm during the overnight hours as temps fall into the lower to mid 70s area wide.

NEAR TERM
Issued at 226 PM EDT Mon Jul 14 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

An area of weak low pressure has developed over the Gulf Stream off the east coast of FL today. This low will enhance ENE flow shifting the Atlantic sea breeze further inland this afternoon.
The late start to convection today has allowed for temperatures to soar into the low to upper 90s and heat indices approaching Heat Adv criteria. High DCAPE over our inland areas and a moist airmass (PWATs ~ 2 in) will promote some stronger wet microbursts with gusty winds to 40-60 mph possible and localized flooding. The best chance for isolated strong/severe storms will be mainly where the sea breezes collide between US 301 and I-75 corridors late this afternoon into evening. The low will gradually shift westward toward central/north-central FL tonight into early Tuesday morning. Overnight lows will be in the 70s.

SHORT TERM
(Tuesday through Wednesday night)
Issued at 226 PM EDT Mon Jul 14 2025

Low pressure over the area Tuesday will shift to the west Wednesday out into the northern Gulf. PWAT values over the area will be highest over northeast Florida and along the coast by the afternoon, providing enough moisture for localized heavy rainfall.
Winds coming in off the Atlantic will help push afternoon sea- breeze convergence towards I-75 where a few stronger storms could start to develop in the afternoon and evening time frame. High daytime temperatures will be a few degrees cooler than previous days, with temperatures in the low to mid 90s over southeast Georgia and upper 80s to low 90s over northeast Florida. Overnight temperatures will be in the low to mid 70s area wide, staying slightly warmer in coastal areas.

LONG TERM
(Thursday through next Monday)
Issued at 226 PM EDT Mon Jul 14 2025

High pressure builds in from the east and sticks around through the end of the period as low pressure in the Gulf moves further west. Plenty of moisture over the area and diurnal heating with winds mostly from a southerly direction will help continue the afternoon rain and storms trend. Temperatures will slowly increase into the weekend with temperatures above the seasonal average.

AVIATION
(00Z TAFS)
Issued at 835 PM EDT Mon Jul 14 2025

Showers and storms have cleared the area. Near calm winds expected along the TAF sites this evening, with easterly-southeasterly winds developing around 13Z/14Z. Period of MVFR cigs during the early daylight hours along the coast TAF sites. Showers and storms activity likely to begin around the mid afternoon, PROB30 groups for now.

MARINE
Issued at 226 PM EDT Mon Jul 14 2025

A weak area of low pressure has developed over the Gulf Stream today and slowly shifts westward into the coastal waters tonight. Showers and thunderstorms will then increase in coverage on Tuesday and Wednesday as the low shifts westward across the Florida peninsula and into the eastern Gulf, with low pressure potentially strengthening later in the week near the northern Gulf coast. NHC has highlighted the northern Gulf coast for a low chance of tropical/subtropical development for this week. Prevailing northeasterly winds today will shift to southerly by late Tuesday as the low shifts west of our local waters, with south- southeasterly winds briefly strengthening to Caution levels near shore on Wednesday afternoon.
Rounds of showers and thunderstorms will continue through late in the week as southerly winds prevail.

Rip Currents: Moderate risk of rips with surf/breakers of 1-2 ft today. Threat begins to increase Tuesday into mid-week as flow slowly becomes more onshore.
