.SHORT TERM...
(Today through Saturday)
Issued at 348 AM EDT Fri Jul 12 2024

Warm, benign weather is expected through the short term period.
Coastal low pressure area over the South Atlantic Bight, just in the
periphery of the Bermuda ridge, will provide tropical moisture into
the Carolinas and far eastern Georgia this afternoon and into
Saturday. As a result, expect warming trend to continue into the
weekend, with temperatures and dew points increasing by a few
degrees each day. Heat Index values will be in the upper 90s to low
100s, and remain below Heat Advisory criteria through Saturday.
Forecast grids continue to include slight to chance PoPs for east
central Georgia for this afternoon and Saturday, but tight PoP
gradient will restrict chances close to the South Carolina border.

Into the weekend, sunny skies will be marked by building CU field
and widespread CU/stratus spreading in from the east. Winds will be
light and variable.

.LONG TERM...
(Saturday night through Thursday)
Issued at 348 AM EDT Fri Jul 12 2024

-Hot

-A break from the heat might be possible late next with a possible
front.

These next couple of AFDs are primarily going to be me trying to
figure out how to say Hot in new and exciting ways. High pressure
builds off the coast this weekend and we get stuck in weak zonal
flow well into next week. Chances for any meaningful precip will
likely not show up until a cold front pushes in Wednesday night and
into Thursday of next week.

The chance of afternoon thunderstorms over the weekend and into
early next week will be limited to the far southern portions of the
CWA and even there, it seems unlikely. Dewpoints will be in the 70s
south of Columbus to Macon, but given mid level dynamics and no
significant forcing at the surface there won`t be much to work with
as far as lift goes.

To drive the point home: Hot. Expect Heat Indices to be in the
triple digits for most of the CWA with the exception of the
mountains until the middle of next week. Overnight lows will be in
the mid 70s which won`t provide much relief and will result in an
early start to the heat.

.AVIATION...
(18Z TAFS)
Issued at 142 PM EDT Fri Jul 12 2024

VFR conditions are expected to persist through the period. A SCT-
BKN cu field between 060-080 has developed and is expected to
persist through the afternoon hours. Isolated SHRA/TSRA in
portions of far east Georgia this afternoon should stay away from
all TAF sites. Winds will be primarily light through the remainder
of the day and tomorrow, at 6 kts or less. Winds are expected to
shift to NW by 19-20Z this afternoon, becoming light and variable
after sunset. On Saturday, winds will come up from NE in the early
morning, shifting to NW by 17-18Z.

//ATL Confidence...18Z Update...
Medium confidence on wind directions.
High confidence on all other elements.
