.SHORT TERM...
(This evening through Wednesday)
Issued at 310 PM EDT Tue Apr 23 2024

An overall quiet period through the next couple of days. High
temperatures will be in the 70s and around 80 further south. Lows
in the upper 40s to low 50s. Our only feature of interest comes from
a boundary (I struggle to call it a cold front) that moves southward
through the area tomorrow afternoon. A few showers may be possible
along I20 and South, however these will likely be isolated at best.
The problem with this is the stable sfc high which continues to sit
to our east, keeping us drier during the boundary passage, and
suppressing any upward motion. Therefore, have left PoPs spotty and
below 25 percent at its highest.

Fire weather wise, winds may be slightly gusty but overall will
mostly stick to around 10 mph. RH values will remain above any 30
percent, particularly since we should begin moistening tomorrow
afternoon and evening.

.LONG TERM...
(Thursday morning through next Monday)
Issued at 310 PM EDT Tue Apr 23 2024

As the extended period begins on Thursday morning, surface high
pressure will be centered over the Great Lakes region, which will
advance a weakening cold front into central Georgia. Low
temperatures on Thursday morning will be in the upper 40s to low 50s
in north Georgia behind the front, and in the mid to upper 50s ahead
of the front. As the surface high pressure moves away to the east
and a low pressure system develops to the east of the Rockies, the
frontal boundary is expected to lift back to the north as a warm
front on Thursday into Friday. Isolated showers and increased
coverage will be possible in the vicinity of the front, although
widespread rain is not anticipated at this time. High temperatures
on Thursday will range from 0-4 degrees above daily averages, in the
upper 70s in north Georgia and low 80s in central Georgia. As the
aforementioned high pressure sets up over the New England area on
Friday, a CAD wedge is expected to develop along the lee side of the
Appalachians and spread into northeast Georgia. Here, temperatures
are forecast to be cooler and limited to the 60s to low 70s.
Elsewhere across the forecast area, highs on Friday will once again
range from the upper 70s to low 80s.

Friday into Saturday, pronounced mid-level ridging will take hold
over much of the eastern CONUS. Meanwhile, the low pressure system
to the east of the Rockies will advance northeastward, riding the
north side of this ridge towards the Great Lakes region. The cold
frontal boundary and associated precipitation expected to stall out
before reaching the forecast area. The gradual warming trend will
continue through the weekend as 1000-500 mb thicknesses increase
under the influence of the ridge. Southwesterly flow aloft will set
up on the back side of the ridge in the later part of the weekend,
which will also lead to moisture return and increasing cloud cover
in the forecast area through the weekend. A second low pressure
system will advance northeastward along roughly the same track as
the first on Sunday into Monday. While a cold front extending from
the south of the low will bring the next appreciable chance for
showers and thunderstorms to the area, long-term guidance continues
to trend slower with the progression of this system, with
precipitation spreading into north Georgia by Monday afternoon,
spreading southward overnight into Tuesday.

(00Z TAFS)
Issued at 729 PM EDT Tue Apr 23 2024
VFR conditions expected to continue through the period. Expecting
increasing clouds Wednesday but they should stay above VFR
criteria. We should also see some isolated SHRA/TSRA but it should
stay isolated enough to keep away from the TAF locations. Winds
are out of the SW and will turn to the W by daybreak. They will
continue to turn to the NW through Wed evening. Wind speeds should
stay in the 6-12kt range through the period.
