Atlanta’s Saturday starts sunny but turns stormy fast — expect a high near 92°F with heat index values as high as 99°F, then a 51% chance of showers and thunderstorms rolling in after 2 PM. If you’ve got errands, yard work, or a walk through Piedmont Park on your list, get it done before lunch.
Today’s Setup
West winds at 5 to 10 mph with gusts to 20 mph will usher in scattered to numerous afternoon storms, per the National Weather Service in Peachtree City. Forecasters note precipitable water values approaching 2 inches and DCAPE readings of 800 J/kg or higher, a setup that favors quick, water-loaded downdrafts. A few storms this weekend could turn strong to severe with damaging wind gusts of 50 to 60 mph and hail up to 1 inch, so treat any rumble of thunder as your cue to head indoors.
Best Window To Be Outside
Morning through early afternoon is your window before the atmosphere destabilizes. With heat index values climbing toward 99°F, an insulated water bottle is worth keeping within reach on any midday outing — and don’t skip the sunscreen breaks.

Storm And Power Prep

What To Wear Or Bring
Light, breathable clothes, sport sandals for damp sidewalks, and a rain jacket for the afternoon switch-up. Humidity stays high into tonight’s low of 74°F, with another 30% chance of storms before 4 AM.
Dinner Tonight
