Minor tweaks to low temperature forecast and dew points given
latest trends, but overall forecast is on track. Though some areas
over the interior may drop towards the mid 30s by sunrise,
expecting too breezy for any frost potential. Especially
considering a secondary dry front passes through overnight, which
may stir up the winds a bit and help with CAA continue.

Cool temperatures, dry weather, and clear skies will be in place
through today and tonight as cold dry air settles over the region.
Breezy westerly to northwesterly winds are expected to persist
through the period, acting to inhibit any potential fog
developments overnight and into early Friday morning. High
temperatures today will be in the lower 60s over southeast Georgia
and in the mid to upper 60s over northeast Florida. Overnight low
temperatures will drop down into the upper 30s and lower 40s for
inland areas and in the mid to upper 40s along the coast.

.SHORT TERM...
(Friday through Saturday night)
Issued at 1256 PM EST Thu Nov 21 2024

Dry weather and mainly clear skies, with below normal
temperatures is forecast throughout this period.

The region will be between a trough of low pressure to the
northeast, and building high pressure to the west northwest. Cold
advection will continue on a west northwest flow, with highs in
the upper 50s to lower 60s SE GA, and lower to mid 60s NE FL.

The high will build closer from the west northwest Friday night.
This will be a significantly cooler than normal night. Lows inland
in the mid to upper 30s will be common. Light frost will be
possible inland, but the wind is expected to stir through the
night due to the remaining gradient. While this wind may limit
frost production, it will make it feel cooler with Apparent
Temperature readings dipping into the 30s all the way to the
coast.

High pressure will build close Saturday, then overhead Saturday
night. Highs Saturday in the lower to mid 60s expected. Due to the
high overhead Saturday night, winds will fall off to near calm.
With cool and dry airmass in place, with the light winds
temperatures will fall into the mid 30s inland. A few spots in
interior SE GA and Suwannee valley of NE FL could touch 32 around
sunrise Sunday morning.

a little below normal early this period, then above next week.
