.PREV DISCUSSION... /Issued 256 PM EDT Tue Oct 17 2017/

SHORT TERM /Tonight through Wednesday Night/...
Quiet fcst period due to regime dominated by strong ridge. The
enhanced gradient winds should decrease by this evening, though
expecting overall E/NE fetch to persist through Wed. With light
winds (possibly calm in the far north) and strong radiational
cooling expected tonight, the main forecast concern will be with
potential for some patchy frost. Have adjusted guidance blend a few
degrees cooler in the far northeast given how temps verified this
morning, which does result in some locations reaching the mid 30s
with a few hours of supportive lower dewpt depressions. Have
issued a Special Weather Statement accordingly for patchy frost
mention though should mainly be 5-9 AM and limited to Fannin,
Union, and Towns counties - not widespread/confident enough for an
advisory. Otherwise most locations will wake up to low to mid
40s, generally 5- 7 deg below normal.

Wednesday should persist with clear skies and only perhaps some
partly cloudy skies flirting with the far southeast overnight. Highs
expected in the low 70s for most then overnight lows still cool than
normal but moderating a few degrees higher than tonight.

LONG TERM /Thursday through Tuesday/...
No major changes to the forecast needed, as quiet conditions are
expected for the remainder of the week into the latter half of the
weekend.

High pressure aloft and the surface will continue to build across
the area through the end of the week. Both the ridge aloft and at
the surface will begin to push off the eastern shore of the US by
the early weekend as the next weather-maker moves into the
Mississippi River Valley. A cold front is expected to move through
during the early part of next week, with precipitation chances
increasing Sunday night.

A slight warm up is expected through the weekend, with temps
slightly above normal. Models are showing some cooler than climo
temps behind the cold front.
