Marine Weather and Tide Forecast for Flowery Branch, GA

SHORT TERM
(This afternoon through Sunday)
Issued at 247 PM EDT Sat Jun 13 2026

As of around 1 PM, a Cu field can be seen developing across Georgia as temps sit in the mid 80s to low 90s. With dew points in the high 60s to low 70s, heat indices currently top out at around 103F. As we head into peak heating hours, temps are forecast to rise a few more degrees into the mid to high 90s with heat indices rising to around 105 degrees, highest in the SE portion of the CWA Thus, a Heat Advisory remains in effect through 8 PM for portions of central and SE GA.

Without much forcing, shower chance are largely refined to areas south of I-20 this afternoon with chances remaining at or below 20%. As such, attention will quickly switch to tomorrow where shower and storm chances increase significantly.

Through the night, a surface cold front will continue to trek through the eastern CONUS in association with a mid level low currently moving through NE Canada. Come tomorrow morning, we will find ourselves sandwiched between surface ridging over the Atlantic and the approaching cold front. This will amount to a slightly stronger return flow set up ahead of any convection.
Winds look to pick up shortly after sunrise from the WSW with gusts up to 25 MPH throughout the day. The morning return flow will keep the area primed for convective development with PWATS and dew points remaining elevated.

Convection looks to initiate ahead of the front around 1 PM just to our NW and then move into NW GA. In the last model cycle, the potential for severe weather, specifically severe wind gusts, has become a concern. Morning CAMs support the presence of an inverted V profile by midday with DCAPE near 1000 J/KG. While weak shear may inhibit long track severe storms, the environment looks favorable for quick downbursts that could easily product severe wind gusts. As such, SPC has introduced a Slight Risk for the northern half of GA tomorrow. The moist profile will make heavy rainfall a secondary threat with all storms, with any training convection posing a low risk for flash flooding. While confidence is increasing in the severe threat, uncertainty remains low regarding how far south storms and the associated severe threat will progress. The metro ATL area currently looks to be where storms may weaken and begin to dissipate, but this is subject to change. Please check back for updates and please make sure to remain weather aware. Remember, when thunder roars go indoors!

LONG TERM
(Monday morning through next Friday)
Issued at 247 PM EDT Sat Jun 13 2026

Moving into Monday and the start of the extended range, southern CONUS will be situated at the base of broader mid-level troughing, within a regime of quasi-zonal flow that will linger through the week. With comparably weak flow aloft, the key player for much of our sensible weather Monday through midweek will be an advancing cold front, poised to breach northwest Georgia before stalling out somewhere across the midsection of the state. Bolstered lift/forcing along the anchoring front combined with abundant moisture streaming in off of the Gulf (progged PWATs as high as 2") will support chances for showers and thunderstorms that exceed that of a typical, summer-like day. The caveat here is that locations north of the stalled front will likely experience only isolated to perhaps scattered convection, and there is still substantial model variability in positioning of the aforementioned front. This is especially evident when viewing spread in 24-hr precipitation totals for late Monday in Atlanta, where the 25th percentile is effectively negligible (<0.1") and the 75th percentile is nearly 1.5".

All this to say, expecting a more cloudy and rainy, and thus cooler, stretch between Monday and Wednesday. Highs for most through midweek will be in the upper 70s to mid-80s, as much as 6-10 degrees below average for mid-June.

Thursday and beyond, any lingering frontal forcing will have dissipated, and the western periphery of the Bermuda high is progged to nudge onshore. Temperatures will begin a gradual uptick through the remainder of the long term.

AVIATION
(06Z TAFS)
Issued at 201 AM EDT Sun Jun 14 2026

Challenging forecast for todat with scattered to widespread thunderstorm activity expected at all TAF sites. Storms will be possible from 15Z, with peak of activity centered from 18-00Z, and some additional storms or rain possible until 04-05Z. Cigs likely to move in with any convective activity, and otherwise cu field expected during afternoon hours. Winds remain on west side 7-12 kts, some gusts up to 20 kts possible. Overnight IFR/MVFR cig development possible by end of TAF period, but uncertainty around this driven by rainfall.

//ATL Confidence
06Z Update
Medium cigs, high all others.
