SHORT TERM

(Today through Thursday) Issued at 314 AM EDT Wed Jun 11 2025

Key Messages:

- Isolated showers and thunderstorms across central Georgia this afternoon and evening, drier over north Georgia.

- Increasing moisture on Thursday with scattered to widespread showers and thunderstorms across north and central Georgia.

A frontal boundary is slowly pushing across the ATL metro early this morning, with areas of fog and mostly clear skies along and north of the boundary, and a few showers and thunderstorms to the south across central Georgia. This boundary will push a little bit further south into central GA by later on this morning, and act as a barrier for afternoon convection. Current thinking is that it will stall just north of a line from Columbus to Macon, with isolated showers and thunderstorms this afternoon and evening to the south of the boundary. A few storms could be strong with gusty winds, small hail, and frequent lightning, but severe weather is not anticipated.

Thursday will be the start of a transition to a period of wetter weather that will last through at least the upcoming weekend. This shift will be driven by the combination of a closed upper level low lifting across the ArkLaTex region and a ridge centered off the east coast of Florida. Low to mid level flow across Georgia will turn out of the south-southwest in response, bringing plentiful moisture (PW values rising from 1"-1.5" to around 1.5"2") into the region. Add in some daytime heating (1000-1500 J/kg MUCAPE) and scattered to widespread showers and thunderstorms will develop across north and central GA, especially during the afternoon and evening. We could see a strong storm or two with gusty winds, but severe weather is not anticipated due to weak wind shear.

High temperatures will be in the mid to upper 80s each day, with tonight's lows falling to the mid to upper 60s in north GA, and upper 60s to low 70s in central GA.

LONG TERM

(Thursday night through Tuesday) Issued at 314 AM EDT Wed Jun 11 2025

Key Messages:

- Enhanced moisture will continue across the region under the influence of southerly flow.

- Diurnally driven rain chances expected through the extended period.

By Thu night the Bermuda like surface ridge centered over the western Atlantic will have weakened a bit and pulled away slightly from the SC/GA/FL coast. With the this ridge weakening, very good gulf moisture streams around the ridge putting GA in good moist southerly flow. This ridge stays fairly stationary through the weekend keeping GA in a very wet pattern. By Mon, the ridge slides a bit further south allowing the over all flow to become a bit more westerly. This will let shortwaves over the Mid MS river valley to move in across the area Mon and Tues. As such, an active weather pattern is forecast to persist into next week, with PoPs around 65- 85%. PWs stay in the 1.5" to 2.5" range through the extended periods. Instability indices will also be diurnally driven with capes getting up into the 500-1500J/Kg range everyday.

Daytime highs will be mainly in the 80s each day with night time lows in the 60s to near 70.

AVIATION

(12Z TAFS) Issued at 637 AM EDT Wed Jun 11 2025

VFR conditions prevail aside from some patchy fog bringing MVFR VIS to a few of the sites which will clear by 14Z. Can't rule out a SHRA/TSRA near ATL today, but the better chances for SHRA/TSRA will be at CSG/MCN from 20-02Z. Winds generally light and variable through this morning, turning primarily out of the W/NW at 7kts or less during the day. MVFR or lower CIGs may develop after 08z Thursday morning.

//ATL Confidence...12Z Update... Medium confidence in this mornings CIG/VIS restrictions. High confidence all other elements.
