Area Forecast Discussion
National Weather Service Peachtree City GA
325 PM EDT Wed May 24 2017


.SHORT TERM /Tonight through Friday/...
Complex system moving across the CWA with rotating cells
continuing across central GA. Will continue the Tornado Watch for
mainly the eastern half of the CWA along and ahead of the main
area of convection. Drier air is already moving into western GA
and this will continue to be the trend. Will end the pops from the
west through this evening, however the cold core H5 low will move
over the CWA and this will keep northern GA unstable enough for
scattered showers through the night. The H5 low move rapidly into
the Carolinas however with daytime heating and the proximity to
the cold core, there will continue to be scattered showers/tstorms
over northeast GA through much of Thursday. Skies become mostly
clear Thursday night and Friday. Winds will be gusty Thursday but
should diminish Thursday night and Friday.

.LONG TERM /Friday Night through Wednesday/...
No major changes for the long term. Previous long term discussion
follows...

LONG TERM /Friday Night through Tuesday/... Shortwave ridge of
high pressure will maintain dry and stable conditions through
Saturday, with temperatures quickly bouncing back during the day
Sat.

Moisture will gradually increase this weekend as W/SWerly flow
becomes more pronounced across the region ahead of large upr vortex
dropping south from central Canada over the northern Plains/upper
Midwest. By Sunday and into the first part of next week, several
shortwaves will interact with sufficient moisture and low lvl convg
along a west-east oriented frontal boundary to support an increasing
chance of shower and a few thunderstorms. This "system" is not
looking nearly as impressive as what we`ve been dealing with over
the past few days but it will bring the area more rain, on top of
what we`ve had already. Drier air moves in from the northwest late
Monday into Tuesday with a nearly stationary frontal boundary across
north Florida/south Georgia - where lingering chances for
showers/storms will exist Tuesday. Temperatures into early next week
should remain around normal for late May -- lower to mid 80s for
highs and mid 60s for lows.

.HYDROLOGY...
Storms with brief heavy rain continue across parts of eastern GA
but these are moving quickly and the threat of flash flooding has
ended. Will therefore cancel the Flash Flood Watch.

&&

.AVIATION...
18Z Update...
Main area of convection over the MCN area and another line of
showers and isolated tsra from North GA to near Anniston, AL.
These areas of convection will continue moving east. Behind these
areas are scattered showers. The scattered showers will move
across the forecast area behind the main areas of convection as
they exit the region. The precip will be out of the forecast area
by late this evening. A few showers/tsra will dot extreme north
Georgia tonight but should stay north of ATL and AHN. Cigs mostly
VFR into tonight with MVFR cigs will fill into the region late
tonight. Cigs will lift and scattered by 18Z Thursday. Winds will
be southwest and gusty this afternoon, diminishing tonight and
become west and gusty Thursday morning.

//ATL Confidence...18Z Update...
Low on timing of convection this afternoon.
Medium to high on remaining elements.
