Marine Weather and Tide Forecast for Columbus, GA

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.

LONG TERM
(Monday morning through next Friday)
Issued at 149 PM EDT Sat Oct 17 2026

Dry and Gradually Warming Next Week:

Guidance remains in good agreement on the forecast for much of next week, with a closed mid-level low within broader troughing over the 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 on Monday, to the mid to upper 70s by mid to late week. Overnight lows will remain fairly crisp, ranging from the low to mid 40s early in the week, to the upper 40s by late week.
