.SHORT TERM...
(Today through Sunday)
Issued at 509 AM EDT Sat Oct 10 2026

Isaias has become post tropical but continues to be the major factor
in the forecast for the remainder of the short term. It made
landfall yesterday as a strong Category 2 and the remainder of the
eye continues to make its way north through Alabama. Peak wind gusts
for the metro area are expected after 8 AM and should finally begin
to ease after midnight. Gusts up to 45 MPH will be possible during
this time causing power outages and downed trees.

Rainfall totals through the short term continue to come in at around
2-4 inches, though the possibility for higher totals continues to
dwindle in the areas of the heaviest rain bands this afternoon. As a
result, our flood watch will continue until 8 AM on Sunday. There is
the possibility the end time will change, given the speed at which
the remnants of the storm are moving.

Tropical tornadoes will continue to be a threat that will ramp up as
we introduce some heating to the area. The threat is largely along I-
85 and south though the metro is included in a Marginal Risk as
well. Tropical tornadoes spin up quickly and are often short lived,
but continue to have multiple ways of receiving warnings.

Lingering impacts from the storm are expected to come to an end
Sunday evening as it`s picked up by a strong northerly jet into the
mid Atlantic. It`s still a serious situation, so please continue to
heed warnings and local authorities.

.LONG TERM...
(Sunday night through Friday)
Issued at 509 AM EDT Sat Oct 10 2026

The long term picks up after the remnants of Isaias are not but a
memory. Dry air will settle in across the southeast and bring back a
little bit of summer on the backside. Highs in the mid to upper 80s
are expected as high pressure keeps winds out of the west. Drier
conditions will start off the long term, but as the high slowly
meanders to the east, we`ll start to see a moisture return by the
middle part of the work week brining afternoon heat index values
back into the 90s.

Expect overnight lows to be comfortably in the 50s and 60s for much
of the area with winds becoming light and variable during the
overnight hours. By next weekend, some of the model runs are
beginning to indicate the possibility for a strong cold front to
push down from the north that will bring fall back into the region.
But for the meantime, enjoy a little bit more late summer and plenty
of sunshine.

.AVIATION...
(12Z TAFS)
Issued at 629 AM EDT Sat Oct 10 2026

Strong NE winds to start off the TAF cycle with sustained 20kts and
the occasional gust to 35kts. Winds will continue to to gust to
around 35kts through the rest of the afternoon, though isolated
higher gusts are possible. Low level wind shear will also linger
through the day before resolving after 18Z as the remnants of Isaias
begin to push off to the northeast. MVFR to IFR conditions will
continue for both CIGS and VIS as wind driven rain continues. TSRA
is possible after 14Z.
