Marine Weather and Tide Forecast for Columbus, GA

SHORT TERM
(This afternoon through Saturday)
Issued at 139 PM EST Fri Dec 12 2025

Expect a bit of a pattern shift for the weekend with increasing clouds over north and central Georgia by Saturday afternoon.
Broad, upper level trough traversing the eastern US will guide a subtropical jet shortwave into the area late Saturday and Sunday.
At this time, NBM POPs appear overdone for late Saturday over northwest Georgia, so have backed off slightly in collaboration with neighboring forecast areas. Will continue to watch whether future model runs show better isentropic lift or more impressive condensation pressure deficits over the area. For now, this environment should just be enough to produce isolated very light rain late Saturday.

This event continues into the long term and the discussion continues into the next section.

LONG TERM
(Sunday morning through next Thursday)
Issued at 139 PM EST Fri Dec 12 2025

A weak frontal boundary sinks south out of the upper to mid MS river valley Sat night and pushes quickly through north and central GA by Sun afternoon. As this front moves through we will see some light showers mainly across western portions of the state with 0.10" to 0.25" of precip expected. The biggest issue with this frontal boundary will be the cold airmass that it ushers into the region Sunday.

As the front exits the area Temps will begin to fall across North GA Sun afternoon. Were looking at high temps across the north GA mountains Sun mainly in the 30s with highs in the ATL area in the 40s. Temps fall rapidly Sun evening/night with good northerly flow pushing this dry/cold airmass into the area. Temps expected to bottom out Mon morning in the teens to lower 20s across north and central GA. These will definitely be some of the coldest temps we've seen so far this season. Dewpoints can also be expected to dip down into the single digits Monday afternoon which would help RH values approach minimum values of 25% or below. If this occurs a Fire Danger Statement may be needed. Temps do not rebound much Monday with highs mainly in the lower to mid 40s across the entire area.
Will see lows back down into the 20s Mon night/Tue morning with things beginning to rebound Tues. Will see highs Tue get up into the 50s and into the 60s Wed.

Other than the brief period of showers Sat night into Sun the extended periods are expected to stay dry. High pressure settles in over the region Mon/Tue and keep things precipitation free through day 7. May see some increased cloud cover Wed/Thu of next week as the ridge shifts a bit off the Carolina/GA coast but still no precipitation expected.
