SHORT TERM
(THIS AFTERNOON THROUGH SUNDAY)
ISSUED AT 149 PM EDT SAT OCT 17 2026
NORTH AND CENTRAL GEORGIA ARE SOLIDLY POST-FRONTAL, WITH SUPREMELY
DRY AIR (PWAT OF 0.32" MEASURED ON THIS MORNING'S 12Z SOUNDING, WELL
BELOW THE 10TH PERCENTILE CLIMATOLOGICALLY) OVERSPREADING THE
SOUTHEAST IN ITS WAKE. ENCROACHING MID-LEVEL RIDGING AND SURFACE
HIGH PRESSURE WILL SUPPORT MOSTLY CLEAR, DRY, AND INCREASINGLY
LESS BREEZY CONDITIONS FOR THE REMAINDER OF THE WEEKEND. HIGHS
TODAY AND TOMORROW WILL BE PLEASANT, IN THE UPPER 50S TO NEAR 70.
AS THE CORE OF THE COLD/DRY AIRMASS MOVES IN OVERNIGHT --
COINCIDENT WITH PRIME CONDITIONS FOR RADIATIONAL COOLING UNDER
CLEAR SKIES -- OUR CHILLIEST MORNING OF THE SEASON IS TO COME ON
SUNDAY: WITH LOWS IN THE MID-30S TO 40S. A FROST ADVISORY HAS BEEN
ISSUED FOR PORTIONS OF NORTHEAST GEORGIA WHERE SLACKENING WINDS
(ESPECIALLY IN SHELTERED AREAS) AND TEMPERATURES AT OR BELOW 36
WILL SUPPORT AT LEAST PATCHY FROST FORMATION TONIGHT.
CARE HAS BEEN TAKEN TO ACCOUNT FOR STRONG MIXING POST-FRONT (THAT
OFTEN OVERPERFORMS AVAILABLE MODEL GUIDANCE), AND DEWPOINTS ARE
LIKELY TO PLUNGE INTO THE UPPER-20S TO 30S FOR SOME ON SUNDAY.
PORTIONS OF THE AREA MAY APPROACH CRITICAL THRESHOLDS FOR FIRE
WEATHER TOMORROW AFTERNOON, AND PRODUCT ISSUANCE MAY BE NECESSITATED
-- ESPECIALLY IF GUSTS LINGER THROUGH SUNDAY.

EAST COAST. NORTH AND CENTRAL GA WILL REMAIN DRY IN THIS SETUP, AS
NORTH-NORTHEAST FLOW KEEPS PWATS BELOW 0.5" AND RAIN CHANCES NEAR
ZERO. TEMPERATURES WILL SLOWLY WARM EACH DAY, BUT REMAIN RIGHT
AROUND NORMAL, WITH HIGHS SLOWLY CLIMBING FROM THE MID TO UPPER 60S
