.PREV DISCUSSION... /Issued 342 AM EDT Wed Oct 18 2017/

SHORT TERM /Today through Thursday/...

High pressure will dominate the short term forecast period, with
cooler and drier airmass remaining over the state. Have continued
mention of patchy frost for far NE Georgia, and Special Weather
Statement remains in effect for Fannin, Union, and Towns through 9
AM. Confidence in patchy frost occurring again on Thursday morning
is low, with guidance blend temperatures not dropping low enough to
include in the grids for now. Will allow the day shift to take
another look.

Highs today will generally be in the low to mid 70s, except the 60s
in the NE GA mountains. Thursday, temperatures will be 4-6 degrees
warmer, with temperatures in the low 70s north to near 80s south.
Gradual warming trend expected into the extended periods.

LONG TERM /Thursday Night through Tuesday/...

No significant changes made to the general trends through the long-
term forecast. Period still starts out dry with a gradual warming
trend back to above normal temperatures through the end of the work
week as upper-level ridging builds across the region. Still some
inconsistencies between medium range models concerning the timing/
strength/path of the system early next week. All are still cutting-
off a fairly deep upper low in eastern Texas by Sunday and migrating
it along the gulf coast into the first half of next week. We should
see enough return moisture by Sunday to bring POPs back into the
forecast, but best chances will be Monday/Tuesday as this system
moves east into the region.
