Oklahoma City is starting Wednesday clear and already warm, but the bigger story is waiting for the afternoon: a high near 108 degrees and dangerous heat conditions across the metro. The heat index could reach 109 to 110 degrees, making this a day to rethink long stretches outdoors.
Extreme Heat Warning Runs Through Wednesday Evening
The National Weather Service in Norman has issued an Extreme Heat Warning from 11 a.m. to 8 p.m. Wednesday. Southwest winds around 10 to 13 mph, with gusts near 20 mph, will do little to offset the heat during the afternoon.
Temperatures are expected to climb through the 90s late this morning before reaching the upper 100s from midafternoon into early evening. Skies should remain sunny, and the chance of rain is essentially zero during the daytime.
Only Brief Relief Arrives Thursday
Wednesday night will be mostly clear with a low near 78 degrees, though a slight chance of showers and thunderstorms arrives after 1 a.m. Thursday. The rain chance is about 20%, so most residents should not count on a meaningful overnight washout.
Thursday will be somewhat cooler but still dangerously hot, with a high near 101 degrees and heat-index values up to 105. A few early showers or storms are possible before 7 a.m., followed by mostly sunny skies through the afternoon.
Triple-Digit Heat Sticks Around Into Next Week
The forecast keeps Oklahoma City in a prolonged hot stretch, with highs near 102 degrees Friday, 104 Saturday and Sunday, 105 Monday, and 103 Tuesday. Overnight lows mostly remain in the upper 70s to low 80s, offering limited relief for homes and bodies that do not fully cool down after sunset.
Residents should drink plenty of fluids, stay in air conditioning when possible, avoid strenuous activity in the afternoon sun, and check on older adults, neighbors and pets. Anyone who must work or exercise outside should take frequent breaks in the shade and treat dizziness, confusion or unusual fatigue as warning signs of heat illness.
