Area Forecast Discussion
National Weather Service Peachtree City GA
743 PM EDT Mon Oct 16 2017



.PREV DISCUSSION... /Issued 326 PM EDT Mon Oct 16 2017/

SHORT TERM /Tonight through Tuesday Night/...
Frontal boundary sweeping south and east through the state ushering
in a much drier and cooler airmass. There is still a weak line of
showers over our extreme southeastern CWA but they should push south
of the area over the next few hours. As this cooler drier air filters
into the area temps tonight expected to be mainly in the 40s with
some 50s across central GA and some 30s in the the N GA mountains.
Highs Tuesday will be in the 60s to low 70s across the entire area.
Low temps Wednesday morning will again dip down into the 40s with
some upper 30s in the N GA mountains. Due to the expected minimum
temperatures, have indicated areas of frost in the grids in the far
northeast Georgia mountains. At this time, do not expect the frost
to be widespread due to the dry nature of the airmass.

LONG TERM /Wednesday through Monday/...
Quiet weather on tap for much of the extended portion of the
forecast. No major changes in the forecast.

500mb troughing along the east coast will begin to shift eastward
into the early weekend as high pressure begins to build overhead.
The high pressure aloft won`t last too long, as a digging longwave
trough begins to push east of the Mississippi River Valley by the
late weekend, into early next week.

High pressure at the surface will remain in place until the second
half of next weekend. A cold front is expected to impact the CWFA by
early next week. This next system should bring the best chances for
precip within the extended forecast period.

.AVIATION...
00Z Update...
A drier airmass will continue to filter into the area over the
next 24 hours as high pressure dominates behind the cold front.
Scattered cirrus this evening will eventually give way to clear
skies. NW winds at 00z are expected to shift to the NE between 01-03z
and continue on the east side through the period. Gusts should
lessen overnight before redeveloping at 15-20kts after sunrise
and continue through Tuesday afternoon.

//ATL Confidence...00Z Update...
High on all forecast elements.
