Area Forecast Discussion...Updated
National Weather Service Peachtree City GA
620 AM EST Tue Mar 9 2021

...12Z Aviation Forecast Discussion...

.SHORT TERM /Today through Wednesday/...
Weak upper ridging persists over the region through the period. A
weak short wave moves over the top across the Ohio/Tennessee Valleys
today flattening the ridge a bit, but moisture remains very limited
and only a bit of an increase in upper-level cloud cover expected.
Large surface high dominates the region through the period with the
center shifting just east of the forecast area. Southerly low-level
flow on the back side of this ridge keeps afternoon highs above
seasonal normals each day and brings overnight lows back up to near
normal tonight.

.LONG TERM /Wednesday Night through Monday/...
The extended forecast begins with the high pressure ridge
centered just off the Carolina coast and continuing to dominate
the weather pattern for North and Central GA. This ridge will keep
us in southerly flow so we will see moisture slowly increasing
but still keeping things precipitation free at least through Sat.
The models have been in good agreement with keeping this ridge
over the area through Friday/Saturday but they begin to diverge by
Days 6-7. Both the GFS ans ECMWF keep dry conditions across the
area though Sat but the ECMWF breaks the ridge down a bit faster
allowing precip to move in Sun. Have decided to keep precip out of
the forecast Sun but bring in some low chance PoPs Sunday night
into Monday. Instabilities look rather week so only putting rain
(No Thunder) in the forecast.

Temps will slowly rise through the week with highs expected in
the Mid 70s to lower 80 by the weekend.

.Fire Weather...
Looking at widespread 15-25% relative humidity values again this
afternoon covering the entire forecast area. Duration and 10-hour
fuel moisture conditions favorable for a Fire Danger Statement for
all of our counties again today. Slow increase in low-level moisture
makes conditions a bit more marginal Wednesday. Wind speeds will
remain below criteria to elevate this to Red Flag conditions each
day.

VFR conditions will predominate across the forecast area through

will be light, 5kt or less, and generally from the southwest to
south, becoming southeast to south by this evening.
