SHORT TERM
(This afternoon through Sunday)
Issued at 227 PM EDT Sat Jun 21 2025
Key Messages:
- Warming trend will continue through the weekend and into early next week.
- Isolated to scattered thunderstorms are ongoing across portions of west-central Georgia this afternoon, and will be possible once again on Sunday.
A pronounced upper level ridge has set up over the eastern CONUS, which will continue to strengthen over the remainder of the weekend, eventually reaching a mean high of 597-598 dam over the southern Appalachians by Sunday afternoon. A warming trend will be ongoing through the short term period with increasing 1000-500 mb thicknesses under the high and plenty of sunshine. High temperatures this afternoon will largely range from the low to mid 90s across north and central Georgia. With higher dewpoints in the 70s across portions of west-central Georgia compared to the remainder of the CWA, heat indices in these locations will reach into the upper 90s this afternoon. Furthermore, SBCAPE values here range from 2000-3000 J/kg, which has allowed for the development of scattered showers and thunderstorms. A couple of these storms could become strong and capable of producing frequent lightning and locally heavy rainfall. Furthermore, with DCAPE progged to exceed 1000 J/kg, these stronger storms could also produce gusty downburst winds. Showers and thunderstorm chances will begin to diminish after sunset.
The warming trend will continue on Sunday, with high temperatures forecast to rise into the mid 90s across the majority of the area, which will be 3-5 degrees above daily normals in central Georgia and 5-7 degrees above daily normals in north Georgia. A surface high will meanwhile begin to advance into the Southeast, with dewpoints recovering into the upper 60s to low 70s across the forecast area. As a result, heat indices will range from the upper 90s to low 100s across central Georgia and portions of north Georgia (with the exception of the higher elevations in the far north). SBCAPE values will once again increase to 2000-3000 J/kg in the afternoon, the development of storms could be inhibited by subsidence under the ridge and the resulting inversion at the mid levels. Storm coverage is thus expected to be isolated, though chances will be greatest in the southernmost portions of the area.
While the potential for severe weather is low, a few of these storms could be capable of producing frequent lightning, gusty winds, and locally heavy rain once again.

LONG TERM
(Monday morning through next Friday)
Issued at 227 PM EDT Sat Jun 21 2025
Key Messages:
- The warmest weather of the year so far in Georgia can be expected during the upcoming workweek.
- Vulnerable populations should take precautions to protect themselves from the heat.
- Heat Advisories will be warranted at times for portions of north and central Georgia, especially mid to late week.
Heat will be the headline throughout the upcoming work week as ensemble guidance continues to show high confidence in a heat wave developing across much of the Eastern U.S. The driver of this pattern will be a strong and expansive ridge building over the region on Monday and persisting through at least Friday. While the ridge will peak in 500 mb height (strength) in the Mon- Tue timeframe, the 850 mb temperatures over Georgia will peak from Wed-Fri. A few ensemble members even have the 850 mb temperature approaching 26C over northern GA, which would be near or above the maximum on record, based on observed sounding data from our office. Regardless of whether that happens, the bottom line is that temperatures will be 6 to 12 degrees above normal for this time of year, with highs in the upper 90s to low 100s. Combine this with humid air (dewpoints in the upper 60s / low 70s), and heat index values will range from 100 to 108 degrees. This will necessitate Heat Advisories for some portions of north and central Georgia next week, especially Wed to Fri. The most likely area to meet criteria would be east-central GA, which could see 3-4 days of Heat Advisories. For other areas, including the ATL metro, confidence in meeting criteria is lower at this time, but could increase as we get closer to the peak of the heat wave. Whether an advisory is put into effect or not, vulnerable populations across north and central Georgia will need to take precautions to protect themselves from the heat for most of the upcoming week.
What about rain chances?! The strong ridge will greatly reduce chances for any diurnal showers and storms due to the combination of subsidence and a drier than normal airmass. It's likely that most areas receive zero rainfall between Monday and Friday, but there could be enough moisture around for some diurnal convection to develop, especially by the time we get to Thu/Fri. Any storms that do form during the afternoons in this period could be strong to even near-severe, with damaging winds as a primary threat.
