..RED FLAG WARNING IN EFFECT UNTIL 6 PM EST THIS EVENING FOR
STRONG WINDS AND LOW HUMIDITY FOR FAR NORTH GEORGIA..

* Affected Area...Far north Georgia, including much of the
  Chattahoochee National Forest.

* Timing...Through 6 PM EST.

* Winds...Northwest at 15 to 20 mph with gusts near 30 mph. 
  Gusts over 40 mph possible at elevations above 3000 feet. 
  Winds will subside a little this afternoon.

* Relative Humidity...As low as 20 percent.

* Temperatures...Lower to mid 40s, even at ridge tops.

* Impacts...Due to low humidity and breezy winds, in addition to 
  dry fuels and ongoing significant drought conditions, any 
  fires that develop could spread rapidly. Outdoor burning is 
  strongly discouraged.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

This warning includes the Chattahoochee National Forests. A Red
Flag Warning means that critical fire weather conditions are
either occurring...or will occur within 24 hours.

Please advise the appropriate officials or fire crews in the

.SHORT TERM...
(Today through Wednesday)
Issued at 415 AM EST Tue Nov 28 2023

An amplified upper level flow pattern is in place over the CONUS,
with a deep trough over south Canada extending into north Georgia
and a broad ridge to the west of the Rockies. Over the course of
the day, the axis of the trough will move eastward and clear the
forecast area while the ridge begins to slide southeast towards
the central CONUS. An upper level jet max rounding the southern
periphery of the aforementioned trough is spreading upper level
clouds across the forecast area, although the low-level airmass
remains far too dry for any precipitation chances. Speaking of
which, a cool and dry post-frontal airmass is in place across
north and central Georgia. Low temperatures will start the morning
in the upper 20s roughly north of I-85 and in the low to mid 30s
to the south.

At the surface, strong surface high pressure (1030+ mb) is
centered over the ArkLaTex, and move eastward today along with the
upper ridge. A strong pressure gradient ahead of the high will
lead to breezy winds of 10-15 mph with gusts as high as 25 mph.
Considering the cold morning temperatures and breezy winds, wind
chills are expected to be in the teens in portions of north
Georgia. The breezy winds will also help continue to dry out 10
hour fuels after wetting rain was observed on Sunday and Sunday
night. As the upper jet max drops through east Georgia and South
Carolina and the surface high approaches, skies will clear and a
reinforcing shot of dry continental air will be ushered into the
forecast area. High temperatures in this airmass will struggle to
get out of the 40s north of I-85, and will be in the low to mid
50s elsewhere across the area. Also ran on the lower side of
guidance for dewpoints considering both this reinforcing dry air
and diurnal mixing under the high pressure system, blending in
NBM10, CONSShort, and HRRR solutions. In spite of the cool
temperatures this afternoon, relative humidity values are forecast
to drop to 25-30 percent in the mid to late afternoon.
Considering these RH values, breezy winds, drying fuels, and the
ongoing drought across north Georgia, a Fire Danger Statement has
been issued for the forecast area until 7 PM EST.

Winds are expected to diminish tonight as the high moves closer
to north Georgia. With strong radiational cooling, morning lows on
Wednesday will range from the upper teens in the higher
elevations of far north Georgia to the mid 20s in central Georgia.
With light winds but little low-level moisture, some patchy frost
will be possible. Another clear and dry day is then expected on
Wednesday. High temperatures will be in the low to mid 50s across
the area. Strong diurnal mixing will be possible once again under
the high, and minimum RH values are forecast to range from 22-28
percent across the area. With these RH values and drier fuels than
today, another Fire Danger Statement will likely be needed on
Wednesday.

.LONG TERM...
(Wednesday night through Monday)
Issued at 415 AM EST Tue Nov 28 2023

The long term period picks up on Wednesday night with overnight
lows in the mid-20s to lower 30s. Thursday will be dry amid the
high pressure regime with highs in the mid-50s to lower 60s.
Meanwhile, at the upper levels, a shortwave trough over the Four
Corners will dampen as it progresses eastward. Ensemble guidance
takes this disturbance across the Southeast on Friday along with
an associated surface low. Warm, moist air from the Gulf of Mexico
will be drawn northward into the low pressure system with PWAT
progged to reach 1.0" to 1.5" across the CWA -- on the upper-end
of climatology for this time of year. Widespread showers will move
in across the CWA on Friday with a slight chance of thunderstorms
roughly along and south of I-85. A lack of well-defined
forcing/dynamics suggests that the potential for strong to severe
storms is low. Waves of scattered to widespread showers (PoPs
generally 60% or greater) and isolated thunderstorms will persist
through the weekend into early next week as the CWA remains
downstream of upper-level troughing while continued advection of
GoM air supports a warm, moist environment. Have PoPs decreasing
late Monday night through Tuesday as ensemble guidance depicts the
persistent upper-level trough finally shifting over and east of
the Southeast.

Will need to continue to monitor the potential for flooding
(isolated flash flooding and rises on rivers, creeks, and streams)
as the updated QPF is for widespread rainfall totals of 3.0" to
4.0" with 4.25" to 4.75" along and south of I-85. Swaths of 5.0"
to 5.5" are possible where especially heavy rainfall and/or
repeated rounds of rainfall occur, and at this time, global
ensemble guidance suggests that the southwestern portion of the
CWA is where this is most likely to occur. Already near-normal
streamflows will rise in response to this rainfall and HEFS
(Hydrologic Ensemble Forecasting System) guidance continues to
depict between a 12% and 32% chance for several river gages (most
of which across central GA) to reach minor flood stage within the
next 10 days. Further changes to the QPF can be expected as this
rainfall event draws nearer and hi-res guidance can be taken into
account.

(12Z TAFS)
Issued at 631 AM EST Tue Nov 28 2023

VFR conditions are expected through the period, with high clouds
streaming across the area expected to diminish in coverage through
the morning and early afternoon. Winds will be NW at 7-10 kts
during the early morning before increasing to 10-15 kts with gusts
as high as 25 kts after 14-15Z and through much of the afternoon.
Winds will begin to diminish, with gusts coming to an end, by
22-23Z.

//ATL Confidence...12Z Update...
High confidence on all elements.
