.NEAR TERM... (Through Wednesday) Issued at 204 PM EDT Tue Sep 23 2025
Only minor changes in sensible weather are expected on Wednesday, compared with today. The main change will be enough increase in moisture for a few more air mass seabreeze-inspired showers in the afternoon, mainly over our Florida and far south Georgia counties along the seabreeze fronts.
The increase in moisture will come as a result of low-level flow clocking around from light easterly today to light southerly on Wednesday. The turn to southerly flow will occur as we come into the environment well in advance of a cold front that will be moving across the Arklatex and Mid-South regions late in the day. The air mass across the east-central Gulf is considerably moister today than it is over the tri-state area, so even weak southerly flow will readily infuse more moisture into the air mass. Surface dewpoints of 70+F will become more common along and south of the I-10 corridor.
We will have the same hot afternoon air mass, with non-coastal high temps of 90-95. When factoring in a couple-degree rise in dewpoints, heat index values will reach 95F-102F. Though the calendar now says autumn, it is not yet time to let pumpkin spice amnesia make you forget your heat-related safety tactics.

.SHORT TERM AND LONG TERM... (Wednesday night through Monday) Issued at 204 PM EDT Tue Sep 23 2025
An upper level low will continue to strengthen, broadening a positively tilted trough from the Midwest. Troughing will begin to dig into the Deep South starting tomorrow. The frontal boundary will begin to bring moisture back increasing PWATS to over 2 inches. Height levels begin to drop in the Tri-State area and adiabatic lapse rates begin to steepen providing sufficient support for increased instability in the latter end of the week. These environmental conditions can bring convection capable of gusty winds and frequent lightning and potential hail Thursday afternoon and into Friday. Consequently, SPC currently has a marginal risk for the convective day 3 outlook on Thursday.
Moving into the weekend, wet conditions continue to be expected as the frontal boundary moves through the region. Drier air will be in place following the wake of the front dropping dew points into the mid to low 60s as the frontal passage appears to move through sometime Saturday. Post front, temperatures are expected to increase with max temps in the high 80s to low 90s for the start of next week. The potential for a cut off low to retrograde over the area can enable mid to upper level cloud cover next week before the low gets pulled back into the main flow.

.AVIATION... (00Z TAFS) Issued at 709 PM EDT Tue Sep 23 2025
Light and variable winds overnight and should become southerly during the day while remaining light. Patchy fog with low cigs are likely for our western terminals (DHN and ECP) during the morning hours, and clearing around 14z. VLD also has fog in the TAF due to it being a moistening atmosphere and climatological persistence. VFR cigs are on tap for this afternoon with scattered fair-weather cumulus. There is a minimal chance for isolated showers/thunderstorms during the late afternoon hours; potentially affecting the TLH and VLD terminals.

.MARINE... Issued at 204 PM EDT Tue Sep 23 2025
Surface high pressure along 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 east into the Atlantic in response to an approaching frontal system on Wednesday. Winds turn southerly, followed by southwesterly as the front approaches on Thursday. Winds shift to out of the north/northwest on Saturday following frontal passage. Winds will remain gentle-moderate throughout the forecast period.

.FIRE WEATHER... Issued at 204 PM 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 204 PM 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.
