Area Forecast Discussion
National Weather Service Peachtree City GA
721 AM EDT Sun May 19 2019
.PREV DISCUSSION... /issued 329 AM EDT Sun May 19 2019/
SHORT TERM /Today through Monday/...
A quiet but relatively warm start to the day with current
temperatures still in the 70s over many locations. Some mid level
clouds noted over east and southeast sections of the forecast area,
otherwise mostly clear. Low pops will be the rule for most of today
as precipitable water values drop below an inch for many locations
and 1.15 in at a maximum. CAPE values will also be reduced from
previous days with around 1000 J/KG for far eastern portions. Will
go with isolated pops for these areas, otherwise a dry forecast is
in store for today and this is supported well by hi res guidance.
A front will approach the area tonight and although its looks like
instability will abate by the time it gets to our area, a residual
line of showers will maintain itself. Will go low end chance for now
for the NW tier.
Area of enhanced moisture will settle into the remainder of North GA
for Monday. Instability will increase through the afternoon hours
with CAPE values approaching 1200 J/KG for west central portions.
This combined with PW values of 1.70 inches should allow for mid
range chance pops along the I85 corridor. It will be continued warm
through the short term with the highest temps this afternoon around
90 for the metro and lower 80s for Central GA.

LONG TERM /Monday Night through Saturday/...
The much-discussed upper ridge will dominate the forecast through
the coming week. Persistent dry weather and well above-normal
temperatures will be the result. The upper ridge will continue to
strengthen by late week with temperatures responding accordingly.
Low-to-mid 90s early week will thus be replaced by mid-to-upper 90s
to near 100 in central Georgia by late week into Memorial Day
weekend. Drought conditions will gradually worsen across central
Georgia during this time as the hot temperatures and dry weather
continue. Refer to the climate section below for record temperatures
for the coming week.

.AVIATION...
12Z UPDATE...
VFR conditions to continue for this cycle with in general less
TSRA activity anticipated. In fact, have dropped VCSH at AHN and
MCN although this may need to be upgraded with subsequent
forecasts depending on if any storms develop. A secondary line
will approach overnight Sunday into Monday morning but confidence
in how much of this remains in tact is low. Will just plan on VCSH
aft 10Z for ATl for now with Prob30 from 14Z. Winds to remain on
the west side with low end gusts for ATL.
//ATL CONFIDENCE...12Z UPDATE...
High on all elements.
