Oklahoma City woke up to cloudy skies and mid-morning temps hovering near 75°F on Monday, May 18, 2026, as a stiff south breeze started to crank up across the metro. By this afternoon, highs are still on track for the upper 80s, but the gusty south winds will make it feel warmer and noticeably more blustery. The strongest winds are expected toward evening, turning the afternoon commute into a hang-on-to-your-hat situation and giving unsecured outdoor items a good chance of taking flight.
Afternoon Winds Pick Up
Through the afternoon, look for sustained south winds of 18 to 24 mph, with gusts pushing into the mid 30s and a few stronger bursts possible in wide-open areas. The National Weather Service in Norman has a Wind Advisory in effect through 10 PM CDT Monday, noting that some spots could briefly see gusts as high as 50 mph. High-profile vehicles should use extra caution, and it is a good idea to lock down patio furniture, trash cans and any other loose gear before heading out.
Storms Arrive Late Monday Night Into Tuesday
After midnight, the focus shifts from wind to rain. Showers and thunderstorms are likely after 1 a.m. Monday night into Tuesday morning, with an 80% chance of precipitation overnight and new rainfall totals generally expected between a tenth and a quarter of an inch. Forecasters say the main window for organized severe storms, including damaging wind gusts and a low-end but real risk of an isolated tornado, will come late Monday night into Tuesday as a cold front sweeps through the area. Keep overnight plans flexible and be ready to head inside quickly if watches or warnings are issued.
Plan For The Week
If you have evening events or outdoor chores lined up, plan to bring in light furniture and trash cans early and give yourself extra time on the roads in case crosswinds slow things down. Western Oklahoma is also under Red Flag Warnings this afternoon for critical fire weather, so skip any open burning and follow local restrictions closely.
