SHORT TERM /Tonight through Wednesday Night/...
The over all pattern continues through the short term. We have
been in this pattern for at least 2 maybe 3 weeks now and there
appears to be no changes in the near future. The main east-west
oriented upper ridge continues to control the weather pattern
across the southern CONUS. A wave developing over the northern
gulf is moving onshore the LA/MS/AL/FL coast bringing SHRA/TSRA
to the SERN states. This precipitation is moving northward over
over south GA and is beginning to push into the SW corner of our
CWA. Right now not seeing much thunder for our area...just showers
and they appear to be diminishing as they push northward. With the
increased gulf moisture moving into the region coverage may be a
bit more Wednesday than today. SBCAPE values are expected to get a
bit stronger Wednesday with reading in the 1800-2700 J/kg range so
may see a bit more potential for wet microbursts and lightning.
Temps should continue slightly above normal with Heat Index values
remaining below 105 so no advisory expected.

01

LONG TERM /Thursday through Tuesday/...
No major changes needed to the long term portion of the forecast.

Ridging aloft begins to break down by Friday into Saturday. This
should allow a weak trough to set up across the CWFA. The weak
trough should remain in place through Sunday or early
Monday...before riding begins to build back over the southeast for
the middle part of next week.

A weak lee trough may try to set up across eastern GA, but
overall,high pressure should dominate the sensible weather at the
surface.

Scattered showers and thunderstorms are expected each day and should
be diurnal in nature. No strong indicators for widespread severe
weather are noted at this time.

.AVIATION...
06Z Update...
VFR conditions through the much of the TAF period. Southwest winds
will increase through the morning hours and top out around 7-10kt
during the afternoon. Sct CU field development by mid/late
morning around 6kft with limited convective coverage expected.
Removed PROB30 from all metro TAF sites given persistent
thermodynamic environment and little TSRA formation the last
several days. CU field will erode through loss of heating giving
way to clear conditions again Wednesday night.

//ATL Confidence...06Z Update...
High confidence on all elements.
