.KEY MESSAGES...
Updated at 637 AM EST Fri Mar 6 2026

- Temperatures will remain well above normal (15-20+ degrees)
  through the forecast period, threatening some daily records.

- Scattered showers and thunderstorms can be expected from Friday
  into the middle of next week. A few storms may become strong to
  severe Saturday afternoon, capable of producing isolated
  damaging wind gusts.

.SHORT TERM...
(Today through Saturday)
Issued at 506 AM EST Fri Mar 6 2026

Weak southerly flow out ahead of a more potent trough in the upper
level flow will give us what resembles a summer time convective
pattern this afternoon. As a result, thunderstorm activity will be
difficult to pin down and forecast for. Thunderstorm coverage will
be less than 40% for the day and weak winds aloft means storms that
do form won`t be in much of a hurry to get anywhere.

Fortunately, we`re not expecting widespread severe weather though it
is possible that a few storms could be borderline with temperatures
in the low to mid 80s across the entire CWA. Once the sun begins to
go down, new storm formation is not expected and lingering storms
are expected to fall apart after 02Z but a few could linger across
north Georgia until 06Z.

Outside of thunderstorm concerns, it is expected to feel more like
summer out there than the beginning of March. Highs will continue to
push into record territory reaching the low to mid 80s for most of
the CWA, with overnight lows in the low 60s.

.LONG TERM...
(Saturday night through Thursday)
Issued at 506 AM EST Fri Mar 6 2026

As the extended period begins on Saturday night, much of the
Southeast will be positioned under the western periphery of a
strong subtropical extending through the western Atlantic. Steady
south/southwesterly flow on the edge of this ridge will continue
to stream warm and moist air from the Gulf into the region,
promoting continued warm and humid conditions and a summer-like
weather pattern of diurnally-enhanced showers and thunderstorms
through the weekend and into next week. On Saturday night, a
surface low pressure system to the north of the Great Lakes will
extend a cold front into the Tennessee Valley region. As the axis
of the subtropical ridge slides further to the east, it will allow
the frontal boundary to nudge closer to far north Georgia.
Shortwave disturbances traversing the southwesterly flow aloft
will overrun this front and promote locally higher coverage of
showers and thunderstorms beyond the normal convectively induced
distribution elsewhere. Thus, on Saturday night into Sunday
morning, likely PoPs are forecast in closer proximity to the
front, roughly along and north of the I-85 corridor, with chance
PoPs further to the south. This closely reflects where the
coverage of precipitation is expected to be highest. However,
given PWATs between 1.2-1.6 and the convective nature of the
storms, some variability can be expected, especially where
stronger storms develop and produce locally heavy rainfall.

Low temperatures (and dewpoints) overnight into Sunday morning will
be in the low 60s across the majority of the forecast area, which
will range from 18 degrees above climatological normals in east-
central Georgia to as much as 26 degrees above normal in the far
northern tier. The unseasonably warm condition will allow modest
MUCAPE values to linger well after sunset and into early Sunday
morning. Furthermore, with 0-1 km shear values between 20-30 kt and
deep layer bulk shear values between 30-40 kts to the south of the
front, a few lingering storms will be capable of becoming strong to
marginally severe and developing into loosely organized clusters.
These storms will be capable of producing damaging wind gusts and
frequent lightning. PoPs will be highest during the daytime on
Sunday as the front sinks further south into the area. Rainfall
totals through early next week are forecast to range from 1-2 inches
along and north of I-85 and between 0.5-1 inch to the south.

High temperatures on Sunday and Monday will be in the low to mid 70s
along and north of I-85 due to overcast cloud cover and higher
coverage of showers and thunderstorms. Highs will rise into the low
to mid 80s to the south. Shear and kinematics ahead of the front
will weaken on Sunday into Monday as the front becomes more diffuse
and eventually washes out, which will reduce the risk for organized
severe thunderstorms. Furthermore, with the front dissipating,
little sensible change in the warm and humid airmass is expected in
the wake of the front across north Georgia.

As subtropical ridging becomes re-established over the northern Gulf
and southwest Atlantic on Tuesday and Wednesday, high temperatures
are forecast to climb to their warmest in the period by Wednesday
afternoon. In all but the higher elevations of far northeast
Georgia, highs are expected to range from the low 80s in far north
Georgia to near 90 in east-central Georgia. These highs will range
from 15-22 degrees above normal. With both highs and low
temperatures well above average for early March, we will need to
continue to monitor the potential for record highs and record high
minimum temperatures through much of next week. The next
significant change in the weather pattern is shaping up to be next
Thursday and Friday, when a strong low pressure system
advances a cold front through the area. Much uncertainty remains
with this system`s timing and intensity, which should begin to come
into better focus in the coming days.

.AVIATION...
(12Z TAFS)
Issued at 637 AM EST Fri Mar 6 2026

IFR with a few obs of LIFR are possible from 12-15Z. Improvement to
low MVFR is expected by 16Z. TSRA is possible after 19Z and will run
until 03Z, though confidence in coverage is not might. Winds will be
nearly due south, but should continue to have an easterly component
to it.

//ATL Confidence...12Z Update...

High on all elements.
