NEAR TERM
(Today and tonight)
Issued at 251 AM EDT Fri Sep 20 2024

Another beautiful day on tap for the region as high pressure settles in overhead. Dry and warm conditions are expected with light northeasterly winds under mostly sunny skies. A bit of patchy fog will be possible along the I-75 corridor this morning, but dense fog is not anticipated due to conditions being drier than yesterday.
Highs today are forecast in the mid 80s to low 90s with lows tonight in the upper 60s to low 70s.

SHORT TERM
(Saturday through Sunday night)
Issued at 251 AM EDT Fri Sep 20 2024

Surface high pressure and an upper level ridge build into the region over the weekend with light east and northeasterly flow expected.
Dry air and the broad subsidence over the region will keep rain chances out of the forecast. Expect temperatures above normal and in the low 90s.

LONG TERM
(Monday through Thursday)
Issued at 251 AM EDT Fri Sep 20 2024

Long term guidance remains in good agreement through much of the period. The upper level ridge from the weekend is expected to continue spreading east across the northern Gulf. This should keep temperatures warm and rain chances low to near zero into at least Tuesday and possibly longer depending on how the long range pattern evolves. Temperatures will continue to remain in the low 90s through Tuesday and possibly into later next week.

After Tuesday is when long range models begin to diverge very quickly. Part of the reason is due to the upper level pattern over the continental US and another point of uncertainty is what, if anything, becomes of a potential tropical disturbance across the Caribbean or southern Gulf. The potential disturbance that many ensemble members have indicated next week show the complex pattern that is often known as the Central American Gyre (CAG). Disturbances that originate out of the CAG typically have large uncertainty compared to tropical waves because they form from a very broad area of low pressure. This broad area of low pressure will typically have smaller areas of even lower pressure that rotate around the larger Gyre and are driven by stronger areas of showers and thunderstorms.
Models typically have a hard time identifying which one of these smaller areas of low pressure rotating in the Gyre could become a tropical disturbance. So when you combine the large uncertainty in the Gyre along with uncertainty in the upper level pattern over the continental US it's one reason why ensembles next week still show possibilities from Texas to the East Coast of Florida.
Additionally, all these possibilities are assuming one system even forms at all.

So summing the long term outlook up, we'll be warm and dry through Tuesday but our eyes remain on tropics. By early next week, we'll likely begin to get a better idea if we need to watch for anything moving up out of the Caribbean, but for now enjoy the sunshine and don't forget the sunscreen.

AVIATION
(18Z TAFS)
Issued at 133 PM EDT Fri Sep 20 2024

High pressure continues to build over the TAF sites through the period. Winds NNE to ENE though the period, with the exception of ECP due to sea-breeze shifting the wind to WSW late this aftn.
VFR conditions are expected for all TAF sites, except for another brief period of restrictions in fog at VLD on Saturday morning.

MARINE
Issued at 251 AM EDT Fri Sep 20 2024

Winds remain light and variable and seas remain low through today.
This weekend, easterly winds will become established and hold through the middle of next week. This will lead to an increase of seas of 1 to 3 feet, with the larger waves being found offshore.
Cautionary conditions may be observed next week during the overnight hours if we're able to get the stronger easterly surges.
Dry weather prevails through the weekend, with showers and storms starting to creep back into the forecast early or mid next week.

FIRE WEATHER
Issued at 251 AM EDT Fri Sep 20 2024

Dry conditions and relatively light winds are expected for the next couple of days with high pressure over the area. There are no fire weather concerns at this time.

HYDROLOGY
Issued at 251 AM EDT Fri Sep 20 2024

Dry conditions look to persist through the weekend and into early next week. At this time there are no hydrology concerns; however, it is worth noting that the CPC has above normal chances for precipitation in the 8-10 day forecast. This is likely due to the anticipated development of a tropical cyclone in either the northwest Caribbean or southeast Gulf. At this time it is too early to determine what, if any type, of hydrology impacts we might see. Especially since there is high uncertainty with the ensemble and global models of where this system could go. Stay tuned to the forecast.
