.SHORT TERM...
(Today through Saturday)
Issued at 323 AM EDT Fri May 10 2024

Key Messages:

 - Thunderstorms will bring widespread rainfall to central
   Georgia this morning.

 - A frontal passage today will result in cooler and less humid
   weather on Saturday.

Today and Saturday:

The initial weather concern today will be an MCS moving out of
Alabama. General thinking is that the MCS will track eastward this
morning along an outflow boundary and instability gradient left by
prior convection (from yesterday and overnight). This boundary
currently stretches from south central Alabama into southern
Georgia and is nearly stationary. Assuming storms follow this
boundary, the greatest potential for severe weather though noon
today should be over southern Georgia and the Florida Panhandle.
Any storms in central Georgia should be elevated and working with
an atmosphere that has been chewed up and spit out by several
rounds of thunderstorms over the last 24 hours. Thus the severe
weather potential for places like Columbus and Macon should be
towards the lower end of the scale. The primary hazards with any
stronger storms would be damaging wind gusts or hail. Thunder
could occur as far north as Atlanta this morning, but severe
weather is not anticipated due to a lack of appreciable
instability.

An airmass shift will occur this afternoon as a cold front sweeps
through Georgia. The front will announce it presence via the
arrival of gusty northwest winds this afternoon. Sustained winds
between 10 and 20 mph are expected along with peak wind gusts in
the 25 to 35 mph range. Drier air will move in behind the front
and this will bring any lingering precipitation in central Georgia
to an end this evening.

By Saturday morning a cooler and drier airmass should be firmly in
place across the Southeast. This will set the region up for a very
pleasant start to the weekend, with high temperatures in the mid
to upper 70s and low humidity (35-45%). Northwest winds should
continue in the region on Saturday. While the winds will decline
some compared to today, peak gusts in the 20 to 25 mph range are
still anticipated in the afternoon.

.LONG TERM...
(Saturday night through Thursday)
Issued at 323 AM EDT Fri May 10 2024

Key Messages:

 - Quiet weather will continue in the region Sunday and Monday.

 - Two additional rounds of widespread rainfall are probable in
   Georgia between Tuesday and next weekend.

The Outlook for Next Week:

Next week should begin with a surface high and upper level ridging
over the Southeast. Due to this pattern Sunday and Monday should
feature dry weather and average to slightly below average high
temperatures. Atlanta can expect a high in the upper 70s on Sunday
and a high near 80 on Monday.

Looking further into the upcoming week it looks like the Southeast
will be in for at least two more rounds of widespread rainfall.
Both the GEFS and EPS show consistent signals for a round of
rainfall Tuesday into Wednesday followed by a second round of
precipitation next weekend. The time of year and strength of the
troughs driving both rounds of precipitation suggest at least
some potential for stronger thunderstorms with both events. Some
localized flooding concerns could also develop by next weekend,
and it is worth noting that multiple GEFS and EPS members are
indicating rainfall totals of 2 to 4 inches with second potential
rain event.

.AVIATION...
(12Z TAFS)
Issued at 636 AM EDT Fri May 10 2024

A mix of IFR, MVFR and VFR conditions will occur over the region
through 18Z today. These conditions will primarily be driven by
low ceilings, though scattered showers and thunderstorms will
produce reduced visibilities at times in central Georgia. Showers
and thunderstorms should mostly end by 16Z today, though isolated
showers could pop up between 20Z today and 01Z Saturday in east
central Georgia. The ongoing variable winds in the region should
become more consistent west to northwest winds after 16Z today.
Peak gusts in the 25 to 35 kt range are expected between 17Z
today and 01Z Saturday.

//ATL Confidence...12Z Update...
Overall confidence in the KATL TAF is moderate.
Moderate confidence in the wind forecast.
High confidence in the visibility and precipitation forecast.
Low confidence in the ceiling forecast between 12Z and 16Z today.
