.NEAR TERM... (Through Sunday) Issued at 116 PM EDT Sat Sep 20 2025
The combination of a very weak shortwave trough, the afternoon sea breeze, and generally dry air will lead to only a few very isolated showers and storms this afternoon, similar to previous days. But, it will be quite hot this afternoon with highs in the mid to upper 90s. Any showers or storms that manage to develop this afternoon will fade after sunset. Some patchy fog is possible tonight, mainly in the Florida counties up into Valdosta. Lows will be in the upper 60s to lower 70s.
On Sunday, another shortwave moves into the lower Mississippi Valley with dry air trying to push in from the east. This will keep isolated showers and storms mostly along and west of the Choctawhatchee River basin tomorrow afternoon with rain chances around 20-30%. The rest of the area likely remains dry. Highs will still be warm by late September standards, climbing into the lower 90s.

.SHORT TERM & LONG TERM... (Sunday night through Friday) Issued at 116 PM EDT Sat Sep 20 2025
Another weak shortwave moves across the area Monday, but with some drier air lingering in place, very isolated showers and storms at most would be expected, mainly in the eastern Big Bend. Otherwise, it stays hot and dry through Wednesday as a weak mid-level ridge tries to nose in from the west south of a strongly positively- tilted trough from the Great Lakes into the Plains. Highs climb back to the mid-90s by Wednesday with very low rain chances.
Later in the week, the aforementioned trough to our north poses a tricky forecast and model solutions differ greatly still on the evolution and placement. Cluster analysis via GFS/Euro/Canadian ensembles has about two-thirds of the solutions showing some form of rex block pattern late next week with the trough cutting off south of a ridge over southern and eastern Canada. The other third of solutions is more progressive and doesn`t cut off the western end of the trough. A farther south and/or cut off solution would generally favor better rain chances in our area late week, but a farther north and/or more progressive solution will keep the better rain chances well to our north. Regardless, while rain chances do increase late week to around 40-50%, it`s still of low confidence. Most likely rainfall totals are around half an inch through the end of the week, but the reasonable low-end potential amounts are around a tenth of an inch with a reasonable high-end around 1-1.25 inches.
High temperatures will fall back into the upper 80s with lows in the upper 60s.

.AVIATION... (00Z TAFS) Issued at 704 PM EDT Sat Sep 20 2025
VFR conditions are expected over the next 24 hours, with the exception of patchy fog potential near VLD Sunday morning, where we continue a tempo for this possibility.

.MARINE... Issued at 116 PM EDT Sat Sep 20 2025
Winds will clock around from the southwest to out of the east by late tonight into Sunday as high pressure shifts eastward over the Appalachians. Winds for the most part will remain light to gentle, though some moderate easterly surges are possible, mainly Sunday and Monday nights. Seas will remain around 1 to 2 feet. Winds become more southerly to southwesterly ahead of an approaching cold front late in the upcoming week with an increased chance for

.FIRE WEATHER... Issued at 116 PM EDT Sat Sep 20 2025
Isolated showers and maybe a storm or two will be possible this afternoon near the sea breeze along and south of I-10. A few more showers and storms are possible Sunday afternoon mostly in the far western Florida Panhandle. Otherwise, high dispersions are expected Sunday afternoon over the Big Bend into the I-75 corridor of south Georgia. Min RH values will drop into the low to mid 30s Sunday before gradually rising through the week. Elevated fire concerns continue thanks to drying fuels and worsening drought conditions.

.HYDROLOGY... Issued at 116 PM EDT Sat Sep 20 2025
Any rainfall that falls over the next 5 days will be very isolated and rather light. Mid to late next week, better rain chances return, but rain amounts vary significantly. Regardless, at this point it doesn`t appear that this will be a drought-busting rain event with most likely totals being around 0.25 to 0.75 inches. The high end rainfall totals are around 1-1.25 inches, which is still not quite enough to alleviate the drought. And there`s a low-end possibility that we miss most of the rain with the 10th percentile rainfall around a tenth of an inch.
Given the very hot temperatures, lower humidity, and general lack of appreciable rainfall, drought conditions continue to worsen across the area, in some cases, rapidly. Until a good soaking rain occurs, drought conditions will keep worsening as we enter our driest months climatologically.
