.SHORT TERM...
(This afternoon through Wednesday)
Issued at 227 PM EST Tue Dec 24 2024

Calm and clear through christmas day. Winds light and variable to
non-existent, mostly from the East. Precipitation and cloud cover
in models for Wednesday continue to drop, now dropping to near
zero. This is due in part to increased confidence in the strength
of surface high pressure and a wedge pattern across the region.
Moisture transport over the wedge has decreased as well. Increased
trough development over the southern Plains and western Gulf
states resulting in increased ridging over the southeast. The good
news is that ridging will mean increasing temps through the
coming days. Frost is likely overnight tonight, however this will
be significantly more patchy going into Thursday morning.

.LONG TERM...
(Thursday morning through next Monday)
Issued at 227 PM EST Tue Dec 24 2024

The long term period picks up on Thursday with an active synoptic
pattern that will support gradually increasing rain chances over
the course of Friday afternoon through Sunday morning.

The SREF depicts a wedge in place and ridge aloft at the start of
the period on Thursday. The ridge is progged to remain in place
on Friday while a shortwave trough traverses the ArkLaMiss and
Mississippi River Valley. Meanwhile, the wedge may strengthen on
Friday as increasing moisture advection ahead of the shortwave
supports precip falling into the wedge aloft and in-situ cooling.

The larger-scale trough axis will shift eastward from the Great
Plains to the Great Lakes/Ohio River Valley over the course of
Saturday through Monday. The ensemble guidance is in general
agreement that this longwave trough will deamplify on Monday as a
band of stronger winds approaches from the Pacific Northwest and
merges with the trough. A trailing cold front associated with a
low pressure system progged to traverse the Great Lakes and
southeastern Canada is expected to push through north and central
Georgia on Sunday, during which precip efficiency should be
maximized. There is a slight chance for thunderstorms on Sunday
across portions of central Georgia, where the National Blend of
Models (NBM) has a 20% to 40% chance for SBCAPE to exceed 500
J/kg. Shear profiles will bear watching regarding the potential
for storm organization, given the likelihood for strong winds
aloft with the trough axis in place. The current QPF is for 0.50"
to 1.50" (with the lower totals across the southeast portion of
the forecast area). Up to 2.0" of rain may fall across the higher
terrain of north Georgia.

Temperatures will be near-normal on Thursday and Friday while the
wedge is in place. Temperatures will increase to well-above-
average through the weekend as return flow brings warm, moist air
across north and central Georgia.
