Area Forecast Discussion...Updated for Aviation
National Weather Service Peachtree City GA
640 AM EST Sun Jan 22 2017


.SHORT TERM /Today through Monday/...

The second round of showers and thunderstorms are continuing this
morning. Best instability remains central and south at this time as
the warm front lingers south of Columbus to Vidalia. Currently have
a tornado watch for the last county row of our forecast area and
southward. Main upper system will drop into the lower MS valley this
afternoon and continue into the southern Appalachians tonight. Strong
dynamics are associated with this system and could overcome any
lingering stable air from previous showers. So another round of
possible severe storms is expected for this afternoon and into the
evening. The closed upper low will continue to push across the
Appalachians on Monday with extensive wrap around clouds and
showers through most of the day.

The flash flood watch will continue as is for north and central
GA. Additional storms with heavy rain are possible at any point
in the forecast area.

.LONG TERM /Monday Night through Saturday/...

Minimal changes made to the extended forecast grids. Region gets back
to more seasonal temperatures but should remain dry after mid-week
system passes.
