...Evening Update...

.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.
