Peachtree City, GA Weather

Key Messages

- Rain-free conditions will remain through the end of the work week.

- Near-seasonal temperatures expected with a slight warm up by the end of the week.

- Precipitation chances begin to increase as we get into next weekend.

Short Term

(This afternoon through Tuesday) Issued at 124 PM EDT Mon Oct 26 2026

Current satellite loop shows mostly clear conditions with some high clouds streaming across the region. Models continue to show a fairly strong high pressure ridge centered over Eastern TN keeping North and Central GA precipitation free. The ridge center is expected to move NE and recenter itself across the Mid-Atlantic states by Wed morning. This will keep us in E to NERLY flow through the week and keep things dry as well. This easterly flow is bringing in a bit of moisture return from the Atlantic but not enough for precip chances...just enough to keep keep RH values above critical fire danger thresholds.

Temps staying in the upper 60s to middle 70s through the short term with morning lows in the 40s to near 50 deg. May see some upper 30s across the NE GA mountains Tonight.

Long Term

(Wednesday morning through next Sunday) Issued at 124 PM EDT Mon Oct 26 2026

No major changes in the extended periods. For the first time in a while, we get to talk about the possibility of a small break in our weather pattern that brings some precipitation chances creeping into the forecast (just in time for Halloween, of course).

The work-week continues to look sunny and mild with daily high temperatures in the 70s and daily lows in the 40s and 50s. There will be some variations of a few degrees thanks to some moving pieces aloft on the periphery of the southeast, but the overall sensible weather won't feel much different day to day. Another potent trough diving across the northeast will bring yet another 1035 surface high over the northern Appalachians, bring another psuedo-wedge airmass diving down the Appalachians and into the CWA. This will reinforce the dry, Fall air in place on Wednesday and could even keep highs closer to 70 or even the upper 60s in some places. Weak surface high pressure settles over the area Thursday into Friday and will slowly warm a bit, bringing us into the mid to upper 70s (maybe touching a few 80s in central Georgia by Friday). This airmass is dry and never really accesses any moisture thanks to broad surface low that continues to churn just off the southeast coast, so no precip chances expected.

This all may begin to change a bit going into Saturday. The players will be another strong wave diving across the northern polar jet in the northeast, building southwesterly flow aloft across the south, and a series of shortwaves embedded within that flow. Unsurprisingly, uncertainty in the forecast is somewhat high, as the timing of each of these players may have big impacts on what we see. Of the ensemble members, the scenario which seems to deliver rain has a faster timing of an initial shortwave within that southwest flow that runs into another potential wedge/CAD across us, even if weak. This allow for some additional overrunning of moisture and isentropic lift within the broader lift provided by the weak shortwave that generates some shower potential. As of right now, the 15%-25% PoPs showing up Saturday afternoon into the evening seems in line with the number of models showing something like the above. The rest push better precip chances later due to short wave timing being slower, initial wave being even weaker, etc. Sadly, this means we can no longer say Halloween will for sure be dry, and instead we will need to watch things.
