...Afternoon Area Forecast Discussion...

.SHORT TERM...
(This afternoon through Wednesday)
Issued at 244 PM EDT Tue Mar 26 2024

Highlights:

 - Showers gradually tapering off from the NW this evening and
   overnight.

 - Lingering thunderstorms possible tonight SE of Macon.

Mid-afternoon skies were mostly clouds to cloudy across the area.
Earlier thunderstorms have mostly come to an end across the area for
now other than some isolated storms here and there within a more
stratiform rain area. The greatest instability at this time appears
to be farther to the S, with ongoing storms over the FL panhandle.
Increasing dynamic energy and a modest increase in instability may
lead to more thunderstorm activity tonight across our extreme SE
zones. Additional rainfall amounts this evening and overnight will
average .5-.75", mostly near and SE of Macon. An isolated strong
storm remains possible overnight in the aforementioned areas.

Elsewhere, low clouds, decreasing, mostly light showers, and patchy
fog are expected. Winds will shift to NW overnight, with some cooler
air filtering in behind the front (mid 40s in the NW). Clouds will
thin and lift on Wednesday with highs ranging from the mid 60s
across the N mountains to the mid 70s across the S. Clouds will
scatter out Wed night with lows mostly in the 40s.

.LONG TERM...
(Thursday morning through next Monday)
Issued at 244 PM EDT Tue Mar 26 2024

Kicking off the long term outlook Thursday morning, the stalled front
finally moves out of the area, taking PoPs with it. The expansive
trough finishes pushing through by Friday morning and broad high
pressure ridging builds over the Southeast CONUS. Post frontal
conditions will mean moisture is slow to return to GA, as weak
surface flow through the weekend slowly raises PWATs back above 0.5"
Saturday afternoon. Ridging also means that any shortwave
disturbance will continue to trek around us. Temperatures will
likely rise well above normal, with highs near 80 across North GA
and some mid 80s through central GA. Lows through the weekend will
begin in the high 30s but will progress to the mid to upper 50s by
Sunday night. Our next chance for precip returns as the ridge slowly
drifts eastward Monday into Tuesday. PoPs should remain low though,
as model agreement this far out remain low as well.

.AVIATION...
(18Z TAFS)
Issued at 144 PM EDT Tue Mar 26 2024

Mostly showers or stratiform rain presently occurring across the
Atlanta metro area. Isolated thunderstorms may redevelop through the
rest of the afternoon, mostly near and SE of a CSG to MCN line where
some peeks of sun break out and lead to some increased instability.
The slowing cold front will gradually push SE across the TAF sites
this evening (after midnight at CSG and MCN). The front is expected
to stall SE of MCN later tonight. Cigs are expected to thicken and
lower overnight, with IFR to LIFR conditions forecast. Winds will
subside through the rest of the afternoon, with a shift to NW behind
the cold front.

//ATL Confidence...18Z Update...
High on wind shift timing, wind speeds and rain ending times, medium
for other elements.
