.SHORT TERM AND LONG TERM...
(This Evening through next Tuesday)
Issued at 300 PM EDT Wed Aug 12 2026

Mid level ridging will meander over the northern Gulf coast Thursday
then gradually shift northwest into the Mid-South and southern
Plains Friday and into the weekend, then shift west towards the High
Plains Tuesday as a series of mid level shortwaves ride over the
ridge across the northern states. Despite the mid level height
center moving further west, the ridging actually strengthens this
weekend and sets up through the southeast US. At the surface, high
pressure will essentially remain throughout the Gulf through early
next week maintaining west to southwest low level flow and the
continued influx of Gulf moisture. Subsidence is evident via area
cross sections with dry air at and above 700mb. This will allow some
mixing but with highs in the mid to upper 90s heat indices will
still reach 105-112F Thursday and Friday with heat advisories likely
and will need to keep an eye on coastal sections for an excessive
heat watch.

As the mid level high shifts north into the weekend this will allow
a slug of moisture to infiltrate the area from the east. PWATs jump
up as well as the column above 700mb moistens which will limit
mixing and keep our heat indices elevated. Highs look to approach
the century mark early next week with heat indices in portions of
the area above 113F and possibly necessitating excessive heat products.

As the mid level ridge is nearly overhead, rain chances Thursday and
Friday will be below normal and mainly forced along the seabreeze;
first along the Panhandle seabreeze then move inland with time. As
the ridge moves away this weekend with added moisture, rain chances
are a little higher Saturday and Sunday at 40-60%. However, as the
ridge strengthens into early next week, rain chances decrease
significantly, back to 20-30%.

Bottom line? The hazardous heat wave will continue into next week
with not much relief from afternoon and evening thunderstorms.

.AVIATION...
(18Z TAFS)
Issued at 115 PM EDT Wed Aug 12 2026

Scattered storms are expected this afternoon and evening with the
greatest chances for impacts at KVLD. Outside of convection, VFR
conditions are expected.

&&

.MARINE...
Issued at 300 PM EDT Wed Aug 12 2026

Light to moderate west to southwest breezes will continue into
the weekend as high pressure dominates. A slight uptick in winds
in the nearshore waters and bays is possible as the sea breeze
develops each afternoon. Isolated showers and storms will mostly
be confined to land areas, but nearshore morning showers or storms
could pose a waterspout risk.

&&

.FIRE WEATHER...
Issued at 300 PM EDT Wed Aug 12 2026

Light southwest to west transport winds will continue over the
next few days. Dispersions will be good with mixing heights
generally from 4500-6000 feet. Scattered showers and storms are
possible each afternoon, generally starting near the coast in the
late morning or early afternoon, then moving inland through the
afternoon hours. The exception will be any organized complexes of
storms that would generally move south-southeast. Gusty, erratic
winds and frequent lightning are possible in and near storms.
Otherwise, hazardous heat will be expected each day with highs in
the mid to upper 90s and heat index values of 105-115.

.HYDROLOGY...
Issued at 300 PM EDT Wed Aug 12 2026

Isolated to scattered afternoon showers and thunderstorms are
expected each day. Localized heavy downpours are possible in
heavier convection. Although a few instances of nuisance flooding
may occur, widespread flooding concerns are not expected.
