.SHORT TERM...
(Today through Monday)
Issued at 415 AM EST Sun Nov 24 2024

Key Messages:

  - Monitoring potential patchy river, lake, and valley fog
    development this morning

  - Warming trend the next two days ahead of an approaching system.
    Highs will be in the 60s today and 70s in some locations
    tomorrow.

Forecast:

Monitoring for lake, river, and valley fog across the area. These
have formed in parts of Alabama and Tennessee where moisture is a
bit better. However, seeing some signs of formation starting to
happen in parts of northern Georgia. If formation continues, an SPS
for patchy dense fog may be necessary in these areas.

Upper level ridge will continue to build in aloft today as we are
caught between the large system over the Canadian Atlantic and a
developing system in the Great Plains. Surface winds will be
westerly in response, but should remain on the lighter side. Expect
clear skies outside of some passing high clouds (which will be a bit
more likely in the NW). We will continue a gradual warming trend as
the post frontal airmass modifies with highs in the lower 60s to mid
60s in north Georgia and mid to upper 60s in central Georgia.
Blended in some higher resolution guidance for dewpoints today to
account for some mixing processes NBM may not be capturing as well
in its blend.

Tonight won`t be quite as cold, with temps reaching down into the
40s in most areas. Two factors at play here - a slight increase in
moisture and a corresponding increase in cloud cover. Both are a
response to low pressure system rapidly moving from the Great Plains
into the midwest on Monday, helping drive a cold front into the
Great Plains. This will be our next weather maker going into the
long term forecast below. Highs Monday will be in the upper 60s to
lower 70s, which is 5 to 10 degrees above normal for this time of
year.

.LONG TERM...
(Monday night through Saturday)
Issued at 415 AM EST Sun Nov 24 2024

At a glance:

    - Increasing chances for a rainy Thanksgiving

    - Unseasonably warm week, much cooler weekend

Moving into Tuesday and the start of the long term forecast, a broad
cold front extending from a strong surface low trekking across the
Great Lakes will be making its way into northwest Georgia. Chances
for showers will increase for areas roughly along and north of a
line extending from Columbus to Macon through early Tuesday
afternoon, with the best frontal forcing fizzling out before
completely clearing the forecast area. As it stands, rainfall totals
don`t look to break a quarter of an inch on Tuesday, and areas south
of the Atlanta Metro are unlikely to see meaningful accumulations at
all.

Weak high pressure moves in at the surface to more properly dry
things out for the remainder of the day Tuesday and Wednesday, but
only briefly as more widespread chances for showers and
thunderstorms look to filter in on Thanksgiving Day. Global
models are in good agreement that a swath of deep layer moisture
will overspread the Southeast, but less solid on associated
surface features. The Euro develops and deepens a strong surface
low that treks quickly across the Mid South into the Mid Atlantic,
with a strong front in tow. Rain chances would taper off mid-to-
late afternoon Thursday with this more progressive system.
However, the GFS`s solution resolves a much weaker surface low --
placed further to the south (approximately along TN`s border with
AL and GA) -- and lingers moisture well into Friday morning. Finer
details regarding rainfall will be heavily dependent upon
subsequent model runs. As it stands for the NBM forecast, a
gradient in QPF is likely to be found once precipitation has
cleared south central Georgia: as much as 1-1.5" for areas along
and north of the I-20/I-85 connector, and 0.25-0.75" for area
further south. The amounts are subject to change as this event
moves into the lens of the short term and HiRes guidance, but it
looks like a rain jacket may be necessary for any Thanksgiving
festivities. Breezy conditions are likely post-front Friday, with
tightly packed isobars evident in forecast surface analyses.
Comparably much drier air is ushered in on the heels of the front
to carry us into the weekend, with our clear and very cool
airmass being reinforced by the eastern fringes of yet another
surface high pressure system.

Regarding temperatures, it will be a tale of pre- and post-
Thanksgiving front. Tuesday through Thursday will see highs in the
mid-50s to 60s, while Friday and Saturday will reach into just the
mid-40s to 50s (!). Lows will flip-flop between the mid-30s to 40s
and lower-40s to 50s each day Tuesday through Friday, before
plummeting into the mid-20s to 30s for the weekend following the
stronger frontal passage Thursday.
