.PREV DISCUSSION... /issued 236 PM EDT TUE MAY 24 2016/

SHORT TERM /Tonight through Wednesday Night/...
Ridging influence and the associated dry weather pattern will begin
to weaken its grip through the short term as a more active southwest
flow aloft becomes established by late in the period. Not expecting
any rain chances for this short term forecast package... but would
not be surprised to see an isolated shower develop over the
northeast GA mountains Wednesday afternoon with help from orographic
lift. However... will just show 10-15% pops up that way for now.

Therefore... mainly a temperature forecast with mostly clear skies
and a light southwest wind allowing temperatures to dip into the mid
and upper 50s across most of north GA tonight... with lower 60s
expected further south. The warm southwest flow... coupled with
ample sunshine... will push highs on Wednesday into the upper 80s
for most areas... except cannot rule out a few spotty lower 90s
across the far southern reaches late Wednesday afternoon. Lows
Wednesday night will hold in the 60s across the area as the warming
trend continues under a southwest flow influence.

LONG TERM /Thursday through Tuesday/...
Only tweaks to the long term based on the latest guidance.

Previous Discussion...
General trends through the extended forecast period remain
relatively unchanged. Models still show a rather indistinct pattern
for this region. Overall...large-scale upper-level pattern continues
fairly static with the larger wavelength troughiness stuck across
the rockies and high plains and broad/weak ridging over the east.
Surface ridge shifts far enough east by Thursday for isolated to
scattered convection across the north. By the weekend...both the GFS
and ECMWF showing some manner of easterly wave moving in from the
western Atlantic and flirting with the region. This should be enough
to spread slight chance/chance POPs across the entire forecast area.
Both also linger some type of weak low over the region through early
next week which should keep a diurnally skewed scattered convection
pattern in place through the end of the forecast period as well.
Instability never forecast to be too impressive and no strong
forcing indicated so chances for strong to severe thunderstorms
appear to remain minimal through the period.
