...New AVIATION...
.NEAR TERM... (Today and tonight) Issued at 214 AM EDT Tue Sep 23 2025
Not much in the way of noteworthy weather today-tonight outside of chances for early-morning fog around I-75, and isolated seabreeze convection. Weak surface high pressure anchored along/offshore the Eastern Seaboard fosters easterly winds that will continue to moisten the low levels with dewpoints in the upper 60s to low 70s. A narrow upper-level trough axis bisecting the Tri-State area down to the East Gulf keeps a belt of deeper, tropical moisture over the FL Peninsula, as seen on satellite-derived Precipitable Water. This pattern supports a continued trend of toasty days and unseasonably warm nights/mornings. High temperatures are forecast to be in the low to mid 90s under a mix of sun & clouds while lows only hover around 70 degrees.

.SHORT TERM... (Wednesday through Thursday night) Issued at 214 AM EDT Tue Sep 23 2025
The upper-level pattern becomes more progressive as a broad trough amplifies from the Midwest and takes on a positive tilt during the short-term period. An attendant frontal boundary then drops into the Deep South and become a focus for clusters of showers & thunderstorms. Surface high pressure responds by shifting eastward, thus allowing for low-level winds to veer more out of the SE ahead of the front. Our local airmass should therefore moisten back to levels supportive of deeper convection and subsequent better rain chances, starting Thursday. The incoming rain will be much welcomed given the ongoing drought conditions that has been plaguing us this month.
Environmental conditions based on modeled soundings ahead of the front appear favorable for semi-organized convection capable of gusty winds, frequent lightning, and locally heavy downpours. It would not be surprising to see an SPC Marginal Risk (level 1 of 5) introduced to NW portions of the Tri-State area in future outlooks. High temperatures are forecast to cool from the low-to-mid 90s on Wednesday to more widespread low 90s on Thursday. Overnight lows are slated to be in the very warm low 70s.

.LONG TERM... (Friday through Monday) Issued at 214 AM EDT Tue Sep 23 2025
Wet weather continues into the weekend as the frontal system attendant to a broad positively tilted trough gradually moves across the region. Frontal passage appears to be some time on Saturday or Sunday with drier air filtering in its wake from the north. Thereafter, the forecast becomes a bit nebulous thanks global model disagreement on the evolution of a upper low slated to cutoff somewhere over the SE US, then meander about. Finer details will need to be resolved to yield higher confidence on what our sensible weather will look like. For now, rain chances are blend of the NBM & CONSAll to account for the uncertainty. Regardless, expect widespread high temperatures in the 80s (isolated around 90 degrees) and lows mostly in the 60s.

.AVIATION... (12Z TAFS) Issued at 656 AM EDT Tue Sep 23 2025
The main concern through the early morning hours is the possibility for patchy fog and low ceilings at VLD. Fog and low ceilings will dissipate by mid-morning with VFR conditions expected for the remainder of the day.

.MARINE... Issued at 214 AM EDT Tue Sep 23 2025
A late-night ASCAT pass showed light/variable winds over Apalachee Bay.
CWF Synopsis: Surface high pressure along and east of the Eastern Seaboard fosters easterly winds today with a local shift to southwesterly from the afternoon seabreeze across the immediate nearshore legs. High pressure then shifts farther into the Western Atlantic in response to an approaching frontal system from the west on Wednesday. Winds turn southerly, followed by southwesterly as the front approaches on Thursday. Chances for showers and thunderstorms return to the forecast late week into the weekend. Offshore post- frontal winds on Saturday.

.FIRE WEATHER... Issued at 214 AM EDT Tue Sep 23 2025
Very warm and mostly dry conditions continue the next couple days outside of isolated seabreeze convection. A frontal system then moves into the region and is forecast to bring widespread wetting rains in addition to thunderstorms. Pockets of high dispersions are possible mainly north of the FL state line mid-week. Southeast winds today turn more southwesterly along/ahead of the front by Wednesday.
&&
.HYDROLOGY... Issued at 214 AM EDT Tue Sep 23 2025
Mostly dry weather holds for the next 2 days before a frontal system brings the first meaningful chances for rain this month on Thursday. Widespread amounts of at least a quarter of an inch are likely with isolated 2-inches+ possible from the strongest thunderstorms. These values, while beneficial, are not by any means drought-busting, but it`s a start! The axis of greatest precipitation appears to be the FL Panhandle, SE AL Wiregrass, and parts of the ACF basin. Although look to dry out late Saturday or early Sunday following frontal passage, these conditions may be short-lived depending on the evolution of a cutoff area of low pressure expected to meander about the Deep South. Stay tuned.
