.PREV DISCUSSION... /Issued 325 AM EDT Tue Sep 19 2017/

SHORT TERM /Today through Wednesday/...
High pressure ridge continues to weaken through short term period.
Models are in pretty good agreement with the overall pattern,
showing ripples in the nearly zonal flow through tomorrow
afternoon when a weak short wave moves across north Georgia.
Moisture increases across the area, which will allow for patchy
fog development each day. Increased moisture will also aid in
isolated shower or thunderstorm development this afternoon, mainly
over Northwest Georgia were models showing some instability. Any
showers/thunderstorm that develops will quickly dissipate rapidly
with the loss of heating. As the short wave moves across the area
tomorrow, will again have a chance of showers or an isolated
thunderstorm. With increased moisture over west Georgia have kept
convection there. Guidance temperatures continue to advertise near
normal temperatures, and see no reason to stray far.

LONG TERM /Wednesday Night through Monday/...
So far there continues to be no significant impacts forecast
from Jose and Maria during the long term except to cause a drying
and more stable airmass Sunday into Tuesday, which will lead
to a lack of rain chances across the area.

Until then, still looking at a return to Isolated to scattered,
mostly diurnally favored, convection across the area. This is
due to some increased moisture and a weak upper trough across the
area.

Forecast temperatures will start above normal then return close
to normal over the weekend into next week.
