...Afternoon Area Forecast Discussion...

.SHORT TERM...
(This afternoon through Saturday)
Issued at 244 PM EDT Fri Jul 12 2024

On the western periphery of the Bermuda High, a low pressure
centered near the South Atlantic coast is bringing tropical moisture
into far eastern Georgia. As a result, isolated thunderstorms will
be possible in the far southeastern portion of the forecast area in
the late afternoon hours today. Elsewhere across the forecast area,
benign weather conditions are expected to persist within the
relatively dry airmass. Hot conditions are expected this afternoon
and through the weekend as the gradual warming trend continues.
Apart from the higher elevations of far northeast Georgia, high
temperatures will be in the mid 90s in north Georgia and upper 90s
in central Georgia this afternoon. Low temperatures on Saturday
morning will be in the 60s in far northeast Georgia, and low 70s
across the rest of the forecast area. Highs will be a couple of
degrees warmer across the area on Saturday, and could approach 100
in portions of central Georgia in the peak heating hours. As
moisture continues to spread slowly westward, chances for isolated
to scattered thunderstorms on Saturday afternoon will extend a
slightly further into the area than today. With dewpoints remaining
in the 60s, heat index values are expected to remain below Heat
Advisory thresholds through the period. Winds will be light and
variable today and Saturday.

.LONG TERM...
(Sunday morning through next Thursday)
Issued at 244 PM EDT Fri Jul 12 2024

No major changes to the extended forecast periods...continued HOT.
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 areas of central and south GA and
even there, it appears it will be isolated at best. 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.
