.DISCUSSION...00 UTC surface analysis shows a cold FRONT moving off
the Florida East Coast in association with a 993 MB surface LOW
PRESSURE system across Central New York. Cooler AIR continues to
arrive behind the front, but it isn`t appreciably cold with
dewpoints back nearer the HIGH pressure area over Texas only in the
low to MID 30s. So while a cool down is expected here locally,
extremely cold temperatures are not.

Upper air data from 00 UTC and vapor imagery shows a high AMPLITUDE
TROUGH moving through the Ohio and Tennessee River Valleys. The last
IMPULSE to affect our region is at the base of the trough swinging
through Middle Georgia. The local KTAE SOUNDING shows the drier and
cooler airmass that has arrived. The precipitable water value is
down to 0.39 inches and the entire depth of the sounding is colder
than 24 hours ago.

Remaining forecast concern will be the TEMPERATURE forecast.
Lingering STRATUS behind the front will slow the temperature drop
across Southern Georgia, but clearing skies are arriving elsewhere
across the region. The pressure GRADIENT is light, but still some
light winds are expected overnight so the CURRENT forecast MIN
temperatures in the upper 30s certainly looks good and could be just
a tad on the low side. However, given UPSTREAM readings already in
the low to mid 40s will assume temperatures locally will respond
similarly once the lingering CLOUD cover gets out of here after 06z.
Thus, plan on making no changes to the current forecast.
