NEAR TERM
(Today and tonight)
Issued at 349 AM EDT Sat May 18 2024
One more potential round of severe weather is on tap for this morning and afternoon as we watch the last of a series of disturbances over the last few days finally push through. As of 3am ET showers and thunderstorms were already beginning to develop well off to our west and northwest in southern Louisiana and Mississippi as the shortwave ejects east out of the mid-level trough currently over Arkansas. All these are expected to continue east through the morning and afternoon and bring widespread showers and storms to the forecast area across southeast Alabama, southwest Georgia, the Florida Panhandle and the Big Bend. Surface instability is somewhat lacking currently but plenty of elevated instability is currently in place as evidenced by convection quickly developing to our west as the forcing arrives.
The main challenge this morning and afternoon is the convection evolution. Currently, fairly stable surface conditions are in place thanks to a large outflow boundary from Friday evening storms, but this boundary has largely stopped it's southward progression and across the Panhandle is already starting to lift back north with a more unstable airmass moving in. This is evident by looking at surface obs further west where surface dewpoints are in the upper 70s compared to the low 70s near TLH. As the forcing moves east this morning, we should see a gradual uptick in the coverage of storms. The severe threat these pose will be questionable given the lack of surface based storms overland currently, but with heating of the day and increasing coverage, a gradual uptick in severe probabilities is expected as storms move into the eastern portions of the Panhandle and southwest Georgia around mid-morning. Storms generally get to Big Bend and south- Georgia late this morning and into the early afternoon hours and this is likely when severe probabilities will be their highest (pending a failure mode below not happening).
One potential failure mode for severe weather developing today would be to keep an eye on storms currently across southern Louisiana. With the better surface instability still across the Gulf waters, it's possible the storms ongoing there could throw off a lot of cloud cover and potentially limit low-level instability that can develop across our area later this morning and into the afternoon. Regardless, even if these lower the threat for severe weather, the strong shortwave rotating through and elevated instability should at least pose some threat for isolated damaging wind and/or hail today should the greater instability not develop.
Additionally, precipitable waters remaining high will bring a risk for localized flood due to high rainfall rates in any storms, especially if those storms traverse over areas that received high rainfall amounts on Friday.
SHORT TERM
(Sunday through Monday night)
Issued at 349 AM EDT Sat May 18 2024
An upper level trough will be exiting the region on Sunday with the last of the remaining showers and thunderstorms clearing out through the day. There is a 40%-70% chance for showers and thunderstorms on Sunday however; some storms may be strong to severe for the eastern Big Bend counties and along the I-75 corridor, as it will be warm with dew points in the 70s, and remaining instability. The SPC has highlighted the extreme SE Big Bend in a Marginal (level 1 of 5) Risk for severe storms. Cooler air aloft is expected to filter in by the afternoon from the northwest. Upper level ridging will begin building in the west Sunday afternoon into Monday. PoPs on Monday will be limited to the I-75 corridor at around 35% as a shortwave passes through.
Temperatures for the short term will have highs in the upper 80s to around 90 degrees. Because of the northerly flow, our GA counties may only reach the mid-80s for highs for Sunday and Monday. Overnight lows will be in the mid 60s.
LONG TERM
(Tuesday through Friday)
Issued at 349 AM EDT Sat May 18 2024
Upper level ridging builds through the week, allowing for warming temperatures and mostly dry weather. Highs will be in the low 90s with overnight lows in the mid to upper 60s.
AVIATION
(18Z TAFS)
Issued at 155 PM EDT Sat May 18 2024
Thunderstorms have passed all of the terminals, though we still have some trailing stratiform rain for a few more hours. With subsidence and lack of thermal lift in the mid-cloud covered and rain- cooled air, we will not see much low-level cloud cover through this evening.
Overnight, the moist low-level air mass will support development of stratus and strato-cumulus clouds with mostly IFR ceilings.
These will continue until 2-3 hours after sunrise, then begin to lift with daytime heating later Sunday morning.

FIRE WEATHER
Issued at 349 AM EDT Sat May 18 2024
Fire weather concerns will be low through the beginning of next week. This is mostly due to the wet pattern we're currently in.
While rain chances lessen Sunday and into early next week, the widespread rainfall totals from the weekend will likely have been around 1 to 3 inches which is well above normal for this time of year and no significantly dry air mass is expected into much of next week.
HYDROLOGY
Issued at 349 AM EDT Sat May 18 2024
A Flash Flood Watch remains in effect for the entire region except the SE Big Bend in FL, Lowndes and Lanier Counties in GA, through 4 PM EDT / 3 PM CDT Saturday. Another 1-2 inches is expected with localized higher amounts possible. Due to already saturated soils, flash flooding will be a concern with training thunderstorms. The region along and west of the Apalachicola River Basin is highlighted in a Slight (level 2 of 4) risk for excessive rainfall today, while areas to the east are covered in a Marginal (level 1 of 4) risk for excessive rainfall.
The Withlacoochee River at Valdosta (Skipper Bridge Road) and Quitman as well, as the Ochlockonee River at Concord, continue in minor flood stage.
