.PREV DISCUSSION... /Issued 403 AM EDT TUE MAY 31 2016/

.SHORT TERM /Today through Wednesday/...
Stagnant airmass in place for today with little to no flow and
similar regime for Wednesday although a bit more enhanced moisture
field. Kept mainly slight to low end chance pops for diurnally
driven convective potential and again attainable conditional
instability given good daytime heating and decently steep mid
level lapse rates /esp if you weigh in on the Nam/. Only other
forcing mechanism could be a weak perturbation late today from the
NW. Kept a bit higher chance pops for Wednesday given the better
moisture in place and coverage of any afternoon development could
get more widespread/outflow driven.

Above normal temps continue thru the period and even bumped slightly
warmer than guidance today given how warm we verified
yesterday...expect many areas back in the low 90s.

.LONG TERM /Wednesday Night through Monday/...
General trend of the long term remains consistent among the
models. North and Central GA continue under a weak ridge until the
end of the week with mainly diurnal showers and thunderstorms. The
trough deepening over the northeast states during the Friday and
Saturday time frame should push a front into or close to north GA
for the start of the weekend. The next closed low should push into
the Great Lakes region Sunday into Monday and deepening the trough
farther into the southern states. This should push another front
into GA Sunday and GFS and ECMWF are showing some drying for
Monday as the front pushes southward through the state. Expect
somewhat higher pops for Friday through Sunday with drying from
the north on Monday.

.AVIATION...
12Z Update...
VFR conditions expected to continue and afternoon cu
field in 5-6 kft range. Kept SCT coverage as tomorrow has better
chance for BKN. Big question is what winds will do near KATL...best
thoughts on initial NE then swing NW by 18z with weak mixing then
back on east side for overnight. Could very well have VRB this
afternoon though at least magnitudes should stay under 7kts. Still
low end chance of isolated shower/storm by afternoon into early
evening but too low to include mention in TAF.

//ATL Confidence...12Z Update...
Low on wind direction.
High on all else.
