.SHORT TERM...
(This afternoon through Friday)
Issued at 221 PM EDT Thu Sep 3 2026

It`s another hot afternoon across North and Central Georgia thanks
to the dome of high pressure overhead and ridging aloft still in
place over the MS Valley extending eastward. Current temperature
observations range from 92-97F with heat indices in the upper 90s to
low 100s. Make sure to stay hydrated and take frequent breaks in the
shade if you`re outdoors for an extended period. Similar to
yesterday, there could be a stray shower around late this afternoon
across our northern, western and extreme southeast counties but most
will remain dry. Heading into Friday, the only notable change will
be a slight uptick in afternoon rain chances across our far southern
counties high pressure at the surface begins to slowly weaken and
two weak boundaries one from the northeast and one from north FL
creep towards the area. Wetting rain likely wont be substantial
but coverage and probability of occurrence will be a tad higher
than what we`ve seen the past few days.

Daytime temperatures will continue to remain in the mid to upper 90s
through Friday. Dewpoints in the upper 60s to low 70s will keep heat
indices in the upper 90s to lower 100s. With no significant
pattern shift within the next 36-48hrs, elected to again extend
the current Heat Advisory for Northwest Georgia through Friday
evening. With outdoor activities likely ongoing heading into Labor
Day weekend, potential heat related impacts were also considered.
Additional extensions may be warranted going into the weekend.

.LONG TERM...
(Saturday morning through next Wednesday)
Issued at 221 PM EDT Thu Sep 3 2026

The Bermuda ridge centered off the GA/SC coast continues into the
weekend but it begins to weaken Sat. This ridge continues to keep
things mostly dry but precip chances slowly increase Sat into the
beginning of next week. The models are showing a significant band of
moisture associated with a weak frontal boundary moving northward
out of the Gulf and northern FL Fri. With the ridge in place across
north GA this boundary stalls across south GA but does increases
precip chances across central GA due to its proximity Sat. With the
ridge weakening as we go further into the weekend a backdoor cold
front moves SW out of the Carolinas and into NE GA Sun afternoon.
This front is fairly weak and looses a lot of its strength as it
pushes into the old weakening ridge, but it will be a catalyst for
increased precip chances Sun/Mon. Slightly cooler air is expected
behind the frontal boundary Monday, as a ridge of high pressure
centered over Hudson Bay sinks southward into the Mid-Atlantic
states. There still remains the potential for diurnal convection,
Mon, with things drying back out for Tue/Wed.

Little change in the temperature trends are likely through the
weekend with temps in the middle to upper 90s through Sunday. Will
see slightly cooler temps Mon/Tue/Wed after the frontal boundary
passes through with highs in the 80s to lower 90s.

possible until 01Z up to 20-30 kts thanks to outflow from nearby
TSRA at all sites. As outflows dissipate, winds will go light to
near calm and VRB at most sites overnight. Some IFR cloud cover or
