.PREV DISCUSSION... /Issued 1033 AM EDT TUE JUL 19 2016/

UPDATE...
Modifying this mornings sounding at FFC gives us a CAPE of 4500+.
With surface temps peaking in the mid/upper 90s and seeing that
convection is already developing along the NE Alabama/NW Georgia
border...will increase pops to 50% but may need to increase to
likely category as we see how this unfolds. A few of these storms
could be severe with the main threat being damaging winds.

No other changes planned.

PREV DISCUSSION... /Issued 355 AM EDT TUE JUL 19 2016/

SHORT TERM /Today through Wednesday/...
Upper ridge centered west of the MS river will continue as the
dominant weather feature across the forecast area. Convection
should be mainly diurnal...lasting into the evening. A trough
deepening over the northeast states should help push a frontal
boundary southward into the TN valley this afternoon or
evening...and thunderstorms may focus along this boundary. Models
show some drying into north GA by Wednesday. Not certain at this
time how far south the drier air will get...so have kept a slight
chance of thunder for the north on Wednesday...with chance pops
for much of central GA which should remain in the deeper moisture.
No big changes for temperatures...highs mostly mid 90s. No heat
advisory planned for today...only an isolated area over central GA
may reach 105 heat index.

41

LONG TERM /Wednesday Night through Monday/...
Again looking at large...east-west oriented upper ridge as primary
feature in CONUS weather pattern during long term period. Ridge
just a tad weaker than earlier forecasts but still will steer flow
around the central and mid-south states. Could see a batch of
moisture on the periphery of ridge...associated with overnight
storms and weak lift thurs and thurs night in the state but not
hanging my hat on anything widespread. Hard to see any real drying
in this current set of models. Have kept chc pops in the afternoon
and slight chc pops in the evening and overnight thru fcst.

Still no signs of tropical development in Atlantic basin. Would be
nice to see some shift in that pattern if only to allow a few weak
storms into the Gulf to increase rainfall and drop temps here.
This spotty convection is not helping relieve growing drought
conditions.

.AVIATION...
18Z Update...
Band of convection moving across CSG/MCN areas...should be out of
both areas by mid afternoon. Expect scattered tsra to develop
across north GA and move into central GA later this afternoon with
all activity diminishing after sunset. Some drier air moving into
the CWA Wednesday but could see isolated to scattered tsra develop
again Wednesday afternoon. Winds will be light west to northwest
through the forecast.

//ATL Confidence...18Z Update...
Medium on convection.
High on remaining elements.
