Area forecast discussion, Jul 8, 7:35 AM EDT, 6 hours 18 minutes before

Area Forecast Discussion
National Weather Service Peachtree City GA
735 AM EDT Sat Jul 8 2017

.PREV DISCUSSION... /Issued 354 AM EDT Sat Jul 8 2017/

SHORT TERM /Today through Sunday/...
Short term forecast largely dominated by two features. Weak boundary
has settled over middle Georgia, evident on the water vapor imagery
as enhanced moisture extends from the northern Gulf coast across
Georgia and east of the Appalachians and along the mid-Atlantic
coast. The second feature is another cold front draped across the
Ohio Valley, which models expect to sag southward into north Georgia
today. This front is already serving as a focus for showers and
thunderstorms this morning in Tennessee, and have kept pop chances
higher in north Georgia to account for the expected coverage as the
front drops into the state. Expect storm coverage today to be
highest in far north Georgia due to this feature, and over middle
Georgia as the former boundary confines the best moisture to the
southern CWA. Have highlighted these two areas in the pop and wx
grids as a result. Even with the developing low ceilings this
morning, expect cloud coverage to improve by mid to late morning,
allowing for sufficient insolation and an increasingly unstable air
mass for some clusters of storms, some strong. At this time, SPC has
the area outlooked in a Marginal Risk for severe storms, with the
main concern being damaging winds, heavy rain, and frequent
lightning. Small hail is also possible.

Temperatures remain near seasonal normals, and have used a guidance
blend through the short term.

31

LONG TERM /Sunday Night through Friday/...
The stationary front across the area to start the long term
is expected to dissipate on Monday with just a lingering surface
trough remaining. Shower and thunderstorm chances will favor
central GA Sunday night...creeping north slightly but still
favoring central GA on Monday.

The upper ridge builds over the area for the rest of the long term
with the main high centers well east and west of the area. The moist
airmass over central GA will spread across the entire forecast area.
This will lead to highly diurnal shower and thunderstorm chances the
rest of the long term period as a rather typical summertime
airmass predominates.

Forecast temperatures are expected to run within 3 degrees of
normal this long term period.
