.UPDATE...
Issued at 920 PM EST Thu Nov 14 2024

The primary change made to the short term forecast this evening was
to add patchy fog across portions of eastern Georgia overnight into
tomorrow (Friday) morning, where winds will generally be lighter than
the rest of the forecast area. Elsewhere, any fog should be
localized to bodies of water and valleys.

.SHORT TERM...
(This afternoon through Friday)
Issued at 233 PM EST Thu Nov 14 2024

Surface analysis shows a cold front across far NW GA with a wedge
still in place across far NE GA. The front will continue to push
southward this afternoon, eventually mixing out any remains of the
wedge. High pressure, cooler temperatures and dry conditions will
build in behind the exiting frontal boundary. Temps for Friday will
be near normal values.

Patchy light rain will continue ahead of the front across the far SE
portion of the CWA for the next few hours. QPF amounts will be light
and generally average around a tenth of an inch. Some patchy fog is
possible, but winds speeds should keep widespread and/or dense fog at
bay.

.LONG TERM...
(Saturday morning through next Wednesday)
Issued at 233 PM EST Thu Nov 14 2024

The extended starts out dry and cool with lows Sat morning in the
30s and 40s across the area. High pressure which began to build into
the area from the short term strengthens through the weekend becoming
centered over the Carolinas and N GA by Sun morning. This ridge will
keep things dry but we will see a slight warming trend beginning
Sunday afternoon through Tues.

We will begin to see a pattern change Monday night into Tuesday as
the high pressure ridge shifts eastward becoming centered just off
the GA coast by 12z Tue. A cutoff low begins to develop along the
MX/TX/NM border Sunday morning then moves rapidly NE into the
central/northern plains by Monday afternoon. There is still some
uncertainty with respect to the intensity of the low and how it will
impact Georgia, especially as it gets absorbed by a deep trough
digging into the central CONUS. However, guidance is trending towards
better agreement on a cold front extending from this low advancing
towards the Lower Mississippi River Valley by Tuesday morning. Precip
chances increase from west to east for GA beginning Tue
afternoon/evening as this boundary moves into the region.

Meanwhile, a tropical cyclone is anticipate to be positioned to the
west of the Yucatan Peninsula early Tuesday, then advance
east/northeast through the Gulf of Mexico. Due to the ridge over the
Atlantic coast/west Atlantic blocking northward progression and the
cold front (and aforementioned trough) pushing any potential tropical
cyclone south and east of GA. The models continue to track any
tropical cyclone activity through the Florida Peninsula Wed/Thu.

.AVIATION...
(06Z TAFS)
Issued at 1252 AM EST Fri Nov 15 2024

Low cigs from AHN to MCN and points SE will continue to push SE and
erode from the NW side as drier air filters into the area. More low
clouds are noted on satellite pix across extreme NW GA. Patchier low
clouds and fog are occurring in between these 2 masses of clouds,
including around the Atlanta metro area. Conditions are expected to
gradually improve across the board through the rest of the night. The
lowest cigs and vsbys will continue at AHN (LIFR) for the next few
hours, but even there conditions will show improvement before
daybreak. Skies are expected to clear out by mid-morning at most
locations with generally light NW winds (although a few gusts to 15
kts are possible during the late morning and afternoon).

//ATL Confidence...06Z Update...
Medium on cigs and vsbys through the early morning, high for other
elements.
