Tulsa, Oklahoma – Tornadoes and flash floods remain a serious threat in eastern Oklahoma today as multiple rounds of severe storms target the region.
According to the National Weather Service in Tulsa, a Hazardous Weather Outlook remains active for Tuesday, May 20, with elevated tornado and flash flood risks continuing in eastern Oklahoma and northwest Arkansas, particularly along and southeast of Interstate 44. Supercells with large hail, damaging winds, and heavy rain are possible, and isolated tornadoes may still develop.
Communities in Tulsa, Muskogee, McAlester, and Fort Smith should be alert for rapidly changing weather and avoid low-lying roads. Flash flooding is already underway in areas with 2–5 inches of rainfall since Sunday. Local officials recommend limiting travel in flood-prone zones and keeping phones charged in case of power outages.
Wednesday, May 21, will bring a brief reprieve, with sunny skies and highs near 82°F expected. But another round of thunderstorms is on track for Thursday night into Friday, with heavy rain and localized flooding possible into the weekend.
The extended five-day outlook keeps temperatures in the low-to-mid 80s, with daily storm chances through Sunday. Memorial Day Monday currently shows a 30% chance of showers and thunderstorms, with highs in the mid-70s—cooler than average for late May.
