.NEAR TERM... (Today and tonight) Issued at 227 AM EDT Wed Sep 24 2025
Airmass moistening continues under maritime-influenced southerly flow on the left periphery of surface high pressure ahead of an approaching cold front. This morning starts off unseasonably warm/muggy with patchy fog possible. Temperatures then soar into the low-mid 90s by the afternoon amidst a healthy cumulus field via thermal lift. Expect a rather robust seabreeze later today, which should act as a forcing mechanism for isolated convection along/SE of the I-10 corridor on the FL Big Bend side where current satellite- derived Precipitable Water ranges from 1.5-1.8 inches. Convection appears to linger across parts of the Suwannee Valley this evening near I-75. For tonight, lows merely drop to the low 70s in addition to good chances for patchy fog developing over much of the Tri-State area near sunrise. Isolated showers may approach the coast early Thursday-morning on the heels of moist pre-frontal southwesterly flow. &&
.SHORT TERM... (Thursday through Friday night) Issued at 227 AM EDT Wed Sep 24 2025
Rain, rain will finally be on the way thanks to an approaching frontal system after a bone-dry September to date! Showers with isolated thunderstorms may be ongoing over parts of SE AL and the FL Panhandle Thursday morning before spreading eastward through the afternoon. Environmental conditions appear favorable for semi- organized convective clusters capable of gusty to perhaps isolated damaging winds, frequent lightning, and locally heavy downpours. A Marginal Risk (level 1 of 5) for severe weather is highlighted across SE AL and most of the FL Panhandle & SW GA in the Day 2 SPC Outlook, beginning Thursday morning. High temperatures range from the upper 80s to low 90s.
Very high rain chances are forecast areawide on Friday as the front passes through the region. Expect a widespread soaking rain that will be much welcomed and beneficial to drought-stricken locations. It is unlikely that flooding would materialize as it would take quite a bit of precipitation. However, localized runoff issues are possible in urban, low-lying, or poor-drainage areas. The threat for strong thunderstorms will also continue. High temperatures dip into the 80s via rain-cooled air and thick cloud cover. Low temperatures are forecast to be mostly in the low 70s.

.LONG TERM... (Saturday through Tuesday) Issued at 227 AM EDT Wed Sep 24 2025
Frontal passage occurs some time this weekend with rain chances dwindling from west to east. However, it remains unclear how dry we get or for how long beyond Sunday thanks to the low predictability on the evolution of a meandering cutoff low across the SE US. It is possible that our sensible weather remains unsettled next week if cyclonic flow aloft lingers. High temperatures are forecast to mainly be in the 80s with lows in the 60s.

.AVIATION... (06Z TAFS) Issued at 227 AM EDT Wed Sep 24 2025
The main concern through the early morning hours is the possibility for brief patchy fog and low clouds around VLD, ECP, and DHN. Any patchy fog and low clouds will quickly dissipate after sunrise with VFR conditions expected for the remainder of the period.

.MARINE... Issued at 227 AM EDT Wed Sep 24 2025
A 3Z ASCAT pass showed variable winds below 10 kts.
CWF Synopsis: Surface high pressure off the Eastern Seaboard fosters southerly winds today with a local shift to southwesterly from the afternoon seabreeze across the immediate nearshore waters. Winds turn out of the southwest on Thursday ahead of an approaching the front. Chances for showers and thunderstorms notably increase into the weekend. Winds shift out of the north/northwest on Saturday following frontal passage.
&&
.FIRE WEATHER... Issued at 227 AM EDT Wed Sep 24 2025
A pre-frontal airmass will continue to gradually moisten via southerly winds until the front`s arrival around late Thursday. For today, expect very warm and mostly dry conditions outside of isolated seabreeze convection along/SE of the I-10 corridor generally east of the Apalachicola River. By Thursday, rain chances jump considerably in addition to the potential for strong thunderstorms capable of gusty winds and frequent lightning. Widespread wetting rains appear likely during frontal passage, especially on Friday. Showers linger in the forecast on Saturday, but will be on a diminishing trend from west to east.
&&
.HYDROLOGY... Issued at 227 AM EDT Wed Sep 24 2025
Beneficial rainfall is poised to arrive Thursday into Saturday from a cold front. At a minimum, most folks should expect at least a quarter of an inch during that time frame (particularly Friday) with locally higher amounts beneath the stronger thunderstorms and/or training convection. Given the ongoing (flash) drought conditions areawide, flooding concerns are low. Current Flash Flood Guidance suggests 4-6 inches of rain would need to fall within 6 hrs. We are not expecting our drought to bust from this activity, but it`s a start!
