...New AVIATION, FIRE WEATHER...

.NEAR TERM...
(Today and tonight)
Issued at 250 PM EDT Fri May 24 2024

Isolated thunderstorms will be possible late this afternoon into
the evening hours. The best chance of seeing a thunderstorm will
be in our Alabama and Georgia counties. Temperatures through the
rest of the afternoon are expected to be in the upper 80s to
around 90 with dew points generally in the mid/upper 60s inland,
low 70s at the coast. These values equate to heat indexes in the
91 to 96 degree range. Overnight lows tonight will average in the
low 70s inland, mid 70s near the coast. Low clouds and patchy fog
may develop over some areas overnight.

.SHORT TERM...
(This evening through Saturday)
Issued at 402 PM EDT Fri May 24 2024

A building mid/upper ridge will place our region in a northwest
flow regime aloft. Disturbances embedded in the flow will move
southeastward along the periphery of the ridge. One of these
disturbances is expected to bring a chance of showers and
thunderstorms tomorrow afternoon and evening. We opted to increase
the chance of showers/thunderstorms from 20-30% to 30-40% for
Saturday afternoon. Rain chances are lower near the coast. Given
the moisture, shear, and instability parameters, we cannot rule
out isolated strong to severe thunderstorms. SPC has placed much
of the region along and north of I-10 in a Marginal Risk of
severe weather. Isolated damaging wind gusts and large hail are
possible.

The other story this weekend will be the building heat thanks to the
aforementioned ridge. Higher dew points on Saturday will boost
heat index values up to 100 degrees while actual afternoon
temperatures average in the low 90s. By Sunday, the ridge builds
further bringing both good and bad news. The good news entails a
much lower chance of afternoon showers/thunderstorms. The bad
news is we will likely add another degree or two or three to your
afternoon temperatures and heat index values. Practicing heat
safety (drinking plenty of water, wearing light colored clothing,
etc..) will be a must for those of you enjoying your holiday
weekend outdoors.

.LONG TERM...
(Monday through next Thursday)
Issued at 250 PM EDT Fri May 24 2024

The temperature outlook for Memorial Day and Tuesday is very
similar to Sunday with highs averaging in the low/mid 90s and heat
index values approaching 100 degrees. There is a 20-30% chance of
afternoon showers and thunderstorms north of I-10 on Monday due
to an approaching frontal boundary. The front brings a better
chance of showers/thunderstorms on Tuesday (~30-40%). Once again,
shear and instability parameters will be sufficient for a few
strong thunderstorms. Drier conditions are expected in the front`s
wake. The early outlook for next Wednesday and Thursday features
highs in the upper 80s to low 90s with afternoon dew points
falling into the 50s and 60s (lower humidity). The drier air
would allow for cooler nights, with inland overnight lows in the
mid/upper 60s, low 70s at the coast.

.AVIATION...
(00Z TAFS)
Issued at 707 PM EDT Fri May 24 2024

Another night of light to calm winds, with MVFR to IFR ceilings
expected to affect all terminals after 08z. Lowering vsbys are
possible for the TLH, DHN, and ECP terminals around daybreak.
Borderline VFR cigs are expected to return for the afternoon
hours, but there is a chance for isolated to scattered showers and
thunderstorms after 18z.

&&

.MARINE...
Issued at 250 PM EDT Fri May 24 2024

Light winds and low seas will continue through the holiday
weekend. The lone exception will be if Saturday`s thunderstorms
can make it far enough south to impact winds and seas over the
Gulf. Therefore, locally higher winds and seas cannot be ruled out
near and within thunderstorms on Saturday. West to southwest winds
may increase somewhat ahead of an approaching frontal boundary on
Monday and Tuesday. The front will also bring a chance of a few
showers/thunderstorms. Quiet weather, light winds, and low seas
should prevail in the front`s wake on Wednesday and Thursday.

&&

.FIRE WEATHER...
Issued at 707 PM EDT Fri May 24 2024

Breezy southwesterly transport winds and high mixing heights will
likely lead to high dispersions across the area both Sunday and
Monday. Scattered showers and thunderstorms are expected across
the region Saturday afternoon with gusty winds, lightning, and
small hail possible.

&&

.HYDROLOGY...
Issued at 209 AM EDT Fri May 24 2024

Portions of the Withlacoochee, Ochlockonee, and Choctawhatchee
river basins continue to remain in minor flood as they drain from
last weeks storms. Some points along the Ochlockonee could fall
below flood stage this morning. With the Withlacoochee slowly
draining into the Suwanee, we could see some rises reaching minor
flooding on portions of the Suwanee in the coming week. Overall,
outside of the possible points along the Suwanee reaching flood in
the next week, no other river basins are expected to reach flood
stage this week.

Widespread rainfall totals over the next 7 days will generally
remain around 0.5 inches or less, with portions of SE Alabama
potentially reaching 1 inch of QPF in the next week. This amount
of rainfall is hydrologically insignificant, and will not lead to
additional riverine flooding concerns.
