Friday morning, June 12, is starting off warm and muggy in Oklahoma City, with partly cloudy skies, about 76°F at Will Rogers World Airport, and a light northeast breeze. Forecasters are calling for a 30–40% chance of showers and thunderstorms through the morning, mainly before 1 p.m., before conditions dry out into a partly sunny afternoon with a high near 87°F. The main story, though, hits Saturday, when heat jumps into the mid‑90s and a separate round of storms pushes in Saturday night.
Morning Storms Could Slow Commutes
Scattered showers and a few thunderstorms are most likely in the morning and early midday. Any storm could bring brief heavy downpours and gusty winds, so plan on a little extra commute time and slower traffic. By late afternoon, skies should turn partly sunny across much of the metro. If you have to be on the roads, keep a weather app or local radar close so you can dodge the worst of it.
Weekend Heat Builds Fast
On Saturday, a hot dome settles in, sending highs toward 95°F and pushing heat‑index values up to about 104°F in parts of the metro. Forecasters expect another Heat Advisory is likely for portions of the area Saturday afternoon, so try to schedule outdoor work and workouts early in the day and keep water within reach. The strong afternoon sun will make it feel even hotter than the thermometer suggests.
Saturday Night Storms Have Severe Potential
Showers and thunderstorms are forecast to redevelop Saturday evening and continue into the overnight hours, with a very high chance of storms Saturday night. Some of these could turn strong. "Damaging wind gusts and large hail are the primary hazards," according to NWS Norman. If storms fire along the front, sudden damaging winds and pockets of heavy rain could cause brief flooding in spots.
How To Prepare
Plan to bring outdoor activities inside by late Saturday, tie down or move loose patio items, and charge phones before evening events. Check on neighbors who are older or who do not have reliable air conditioning, and make sure you can move indoors quickly if thunderheads build nearby. For local cooling locations and additional tips, see OKC sizzles under heat advisory or call 2‑1‑1.
