Marine Weather and Tide Forecast for Peachtree City, GA

SHORT TERM
(Today through Tuesday)
Issued at 408 AM EDT Mon Jun 15 2026

Thunderstorms have come to an end across north and central Georgia this morning with only a few showers lingering in parts of central Georgia. Surface cold front is slowly pushing to the south and currently sitting across southern TN, poised to enter north GA over the next few hours. Moist air remains in place ahead of it, while relatively cooler and drier air is behind. Front is forecast to progress through metro Atlanta before stalling across central Georgia. This will create quite the juxtaposition of forecasts across the CWA For north Georgia, highs will be in the low to mid 80s with Tds in the 60s, making for a cool, mild June day. Rain and thunderstorms are not expected. Across central Georgia, highs will be in the upper 80s to 90s with Tds in the 70s. This means "feels like" temps remain well into the 90s with some triple digits possible. What may keep these tampered down a bit will be the afternoon and evening rain and thunderstorm chances, which form a sharp gradient across central Georgia. The further south you are, the higher your rain chances look to be.

Driving these rain chances will be another surge of moisture along and over the stalled frontal boundary ahead of yet another shortwave diving through the broad trough over the eastern CONUS. Stalled boundary will provide a source of lift. Storms and rainfall will impact portions of central Georgia during the afternoon, where HRRR shows MUCAPE values around 500-1500 J/kg. Severe chances are very low given lack of shear, but as always given the time of year, a strong storm that crashes down quickly will be capable of some strong winds. The only caveat to all this is how far south the front gets - if it pushes even further south than forecast, the rain chances go with it.

Tuesday sees another shortwave progress to the north. Tropical moisture continues to surge across the area, being lifted by the stalled boundary over the CWA Widespread cloud cover combined with a northward shift in rain chances into parts of the metro mean that temperatures will be upwards of 10 degrees below average across the CWA Highs will be in the upper 70s and lower 80s - some relief from the past several days for sure. We could see some decent rainfall across parts of the area as well, with HRRR LPMM showing some widespread pockets of 1"+ of rainfall.

LONG TERM
(Tuesday night through Sunday)
Issued at 408 AM EDT Mon Jun 15 2026

The primary feature of interest by mid-to-late week will be a presently-disorganized area of low pressure that is currently outlooked by NHC. At this juncture, eventual development and evolution of this system remains highly uncertain. With that said, the potential for a slug of tropical moisture associated with this system to be shunted northeastward into our area remains a possibility. PoPs trend upward late week given the overall pattern with some potential for heavy rainfall that will be monitored.

Temperatures will be near to even slightly below climatology given potential increased clouds/rainfall coverage. There may be a brief window Thursday that portions of the area could nudge triple digit heat index values.
