News On 6 Alert: Today’s Must-Read Tulsa Headlines, Weather & Live Updates

Residents across Green Country spent the start of Memorial Day weekend under dark skies after a line of severe thunderstorms rolled through northeast Oklahoma late Saturday, knocking out power and triggering flash-flood warnings. According to the latest update from News On 6 meteorologists, the strongest cells developed just after 8 p.m. over Osage County before racing southeast toward Tulsa, producing wind gusts near 70 mph, pea- to quarter-size hail, and more than 4,500 lightning strikes in three hours. Early Sunday, PSO reported roughly 22,000 customers without electricity in the metro, with the highest concentration of outages stretching from Sand Springs to Broken Arrow. Crews worked through the night to clear downed trees that blocked sections of I-244 and clogged neighborhood streets in Midtown and south Tulsa. City officials urge drivers to treat any dark traffic signal as a four-way stop and to avoid high-water crossings, especially along the Mingo Creek and Joe Creek corridors where gauges showed rises of three feet in less than an hour. What’s next in the forecast? • Storm threat lingers: A stalled frontal boundary will keep the atmosphere unstable through Monday afternoon. Scattered strong storms could redevelop, bringing additional 60+ mph winds and localized flooding. • Temperature roller-coaster: Behind the front, highs tumble from Saturday’s 88 °F to the upper 70s Sunday, before rebounding into the mid-80s for Memorial Day parades. • Humidity surge: Dew points remain in the low 70s, meaning any sunshine will quickly refuel storm updrafts. Safety checklist for Tulsa and surrounding counties 1. Charge phones and portable battery packs before the next wave hits. 2. Restock storm kits with bottled water, non-perishable snacks, flashlights, and first-aid supplies. 3. Keep a NOAA weather radio or the News On 6 app handy for real-time alerts and live radar. 4. Never drive around barricades; just 12 inches of moving water can sweep away a car. 5. If your home loses power, turn off major appliances to prevent a surge when electricity is restored. Community resources • Cooling stations: Tulsa County Emergency Management activated cooling centers at the Reed Community Center and O’Brien Park daily from 10 a.m. to 6 p.m. • Debris pickup: The city’s bulky waste crews will run extra routes Tuesday–Friday. Place limbs curbside in bundles under six feet long. • Pet safety: Tulsa Animal Welfare reminds owners that loud thunder can cause pets to bolt; secure fences and update microchip information.
