Marine Weather and Tide Forecast for Marietta, GA

SHORT TERM
(This afternoon through Sunday)
Issued at 132 PM EST Sat Nov 8 2025

Current satellite analysis shows a bubbling cu field across much of the northern portions of the area along with radar showing showers forming along the northern metro area into western GA.
This area will be the main emphasis for severe weather today as also outlined in SPC's marginal risk. Current mesoanalysis shows an area of 2000 J/kg SBCAPE over this area with a push of 2500-3000J/kg from the SW that could reach into the marginal risk area. Effective SRH is also elevated over this area which contributes to the overall risks for today. The main threats we are looking at are hail up to 1 inch and gusty winds but as the morning has progressed the almost zero tornado potential has increased. Parameters currently out there are pointing at single cellular being the storm mode with the potential for some form of low level spin in at least an isolated storm or two. This threat should remain through the afternoon and evening.

Tomorrow the cold front pushes through beginning the march into the colder weather Monday. CAA advection quickly spreads into the area which will help contribute to the breezy NW winds Sunday into Monday currently at 20-25mph with up to 30 mph in the mountains. Did think NBM was a tad too low so did elect to up the winds ever so slightly.

When it comes to snow potential, not much has changed with the threat. As the CAMs have come in they are focusing on an area in the Smoky mountains for the main snowfall which ultimately leaves us in the flurries threshold. The precip will be out of north Georgia for the most part before temps reach below freezing with only a minor overlap in the north Georgia mountains. No impacts are expected at this time.

LONG TERM
(Monday morning through next Friday)
Issued at 132 PM EST Sat Nov 8 2025

The first blast of cold air from a potent cold front on Monday will limit high temperatures to the upper 40s and lower 50s. To get an idea how much of anomaly this front is, High Temps for Monday are expected to be anywhere from 20 to 25 degrees below climatological average. We'll likely break a number of November daily records.
Please plan for the overnight freezing temperatures at the start of the work week.

Dry air filters in behind the front, and we'll slowly see a steady rise in temperatures. Especially in afternoon high temps which are expected to fight their way back up into the low 70s by the end of the work week. Overnight lows are expected to remain close to freezing before also getting a boost as the upper level flow becomes more zonal and we get a slight increase in moisture.

AVIATION
(06Z TAFS)
Issued at 1259 AM EST Sun Nov 9 2025

VFR to start TAF period. Brief period of -SHRA possible from 07Z to 09Z across southern metro TAF sites, including ATL. Uncertain on development of low cigs/FG for morning hours. Leaning away given that showers are still moving across and any low cigs and still yet to show signs of development as of 06Z. Still, with moist air in place and cooling, can't rule it out. Winds pick up during afternoon from W to NW as arctic front moves through.
Expecting strong winds 10-15 kts sustained with gusts to 20-25 kts, possibly higher. Some cloudiness possible as front moves by, but should remain elevated.

//ATL Confidence
06Z Update
Medium morning cigs. High all others.
