.PREV DISCUSSION... /Issued 355 AM EDT Mon Oct 15 2018/

SHORT TERM /Today through Tuesday/...
Main focus will be the slow southeastward progression of a front and
enhanced moisture axis currently draped across the TN valley. Have
trended slight to low end chance pops across portions of our north.
While the far northern tier has the greatest chance for showers and
even some isolated thunder, the Nam 300K theta sfc indicates some
isentropic upglide could aid isolated shower development farther
south along the I-85 corridor by this afternoon. The front has
greater progression tonight into Tuesday so have expanded the chance
pops across the northern majority and into parts of central Georgia
by Tuesday afternoon where the boundary could stall. Also included
slight chance thunder mention for central Georgia in the afternoon
given progged conditional instability present.

Expecting above normal temps this afternoon with low to mid 80s
reached for most locations, then lower at least for north Georgia
Tuesday given aforementioned front and increased moisture/cloud
cover influence.



LONG TERM /Tuesday Night through Sunday/...
The main concern at the start of the long term will be a moist
upper level flow that could cause mainly light showers Tuesday
night and possibly into early Wednesday and mostly favoring
n GA. Instability will be lacking and the shower chances will
dry up later Wednesday.

The next best chance for rain will come Friday night into Saturday
night as an upper level trough brings rather deep moisture
with a cold front forecast to move across the area on Saturday.
At this time, overall instability is lacking so not expecting much
in the way of thunderstorms but may need to be added for central GA
on Saturday if some instability gets generated.

The vast majority of the rain should end by Sunday.

Nighttime temperatures will start well above normal Tuesday night
then bounce above and below normal the rest of the long term.

Initial MVFR deck forming around sites around 1200-1500 ft.
Thinking will lift/scatter after 14/15z then generally SCT cu
field today 4-5 kft. Approaching front late in the period so have
some MVFR cigs and increased SHRA chances after about 09z Tuesday.
Winds mainly light SE initially then swing SW after 17z today,
with west to NW shift early Tuesday morning. Magnitudes under 7
