.SHORT TERM...
(Today through Tuesday)
Issued at 454 AM EDT Mon Oct 12 2026

Clear and pleasant conditions are expected today, and will continue
through the rest of the work week. Temperatures will rise into the
low 80s by early afternoon, but with NW winds we`ll keep our
humidity down. Temps will fall into the low 60s tonight before
heating into the mid 80s tomorrow.

Gradient winds have eased, though we may see a few gusts to 20 mph
this afternoon. The higher elevations of NE Georgia could see gusts
as high as 30 mph as we heat up and mix into a lingering jet at
850mb.

.LONG TERM...
(Tuesday night through Sunday)
Issued at 454 AM EDT Mon Oct 12 2026

The extended periods begin Tue night with a large high pressure
ridge centered over western NC with its ridge axis extending from
the Mid-Atlantic down to the MS/AL Gulf coast. This ridge stays
fairly stationary through Thu keeping things warm and dry but it
does weaken slowly through the end of the week. Temperatures Wed,
Thu, and Fri will be in the 80s to near 90s with lows mainly in the
60s. As this ridge begins to weaken Thu,  a fairly organized frontal
boundary begins to move SE out of the upper to middle MS river
valley. It makes its way SE Thu night to just NW of the AL/GA/TN
border by daybreak Fri. As this front moves SE both the ECMWF and
the GFS show it loosing strength as a lot of its dynamics and
moisture moving NE closer to the parent low center which will be
over the New England states by this time. Just the southern tail end
of this front swings SE through the state Fri/Fri night with the
models showing it moving into N FL by daybreak Sat. If this holds
true all we should see from this frontal passage is maybe some
increased cloud cover but the biggest things we will see is very
Fall like temps moving into the area next weekend.

The models show a very strong high pressure ridge pushing into the
area from the northern/central plains behind the exiting frontal
boundary Fri. This ridge will bring a cooler/drier airmass with it
cooling the Southeastern U.S. off substantially. We could see highs
temps in the 60s and 70s Sat with lows in the 40s Sat night. May
even see some upper 30s across the NE GA mountains. Sundays High
temps expected to be in the 60s. We could literally go from wearing
shorts and short sleeves Fri...to sweaters and jackets Sun morning.
