No changes to current forecast.

.DISCUSSION...
Dry/cool air continues to drive down across the state as
strong/nearly cut-off upper low spins across the Kentucky/Indiana
state line this morning.

After morning lows in the 50s across much of north and central GA, 11am
/15z/ temperatures have rebounded to the upr 60s and 70s. Not
expecting much more warming beyond the next couple hours as a
pronounced NW flow will advect/maintain the cool/dry airmass
across the state. Current forecast in very good shape. No changes
to the hourly grids necessary at this time.

.PREV DISCUSSION... /Issued 707 AM EDT Thu Sep 29 2016/


LONG TERM /Friday Night through Wednesday/...
The extended portion of the forecast remains quiet.

High pressure at the surface will dominate for much of the extended
forecast. The surface ridging begins to weaken by the end of next
week as a cold front begins to approach the Mississippi River.
Aloft, a long wave trough will dominate across the eastern US
through early next week. By the middle of the week, ridging begins
to build across the area. So, will all of this said, a dry and
seasonable forecast will hold.

One thing to keep an eye on though, is the progression of TS
Matthew. For now, both the GFS and ECMWF keep the storm well to the
east of the CWFA.
