The Oklahoma Turnpike Authority says the westbound lanes of Interstate 44, also known as the H.E. Bailey Turnpike, are closed at Mile Marker 58 due to an overturned semi near Elgin.
The storm should stay south of the Oklahoma City metro, but could affect the communities of Dibble, Washington, and Slaughterville.

The tornado may be difficult to see due to rain surrounding a funnel or lowering. Visibility is significantly reduced in the areas around the storm. Baseball-sized hail has been reported, and storm chasers in the area reported overturned semis and damaged mobile homes along Interstate 44.

The National Weather Service has issued a Tornado Watch for the southern half of Oklahoma until 10 p.m., but there’s still quite a bit of uncertainty about what to expect, and where.

“This is different than Tuesday,” said Rick Smith, the warning coordination meteorologist at the National Weather Service’s Norman Forecast Office. “The key features today are this warm front and the dryline, and where that low pressure area is.”
Cool, dry Rocky Mountain air will meet warm, moist conditions from the Gulf of Mexico over central Oklahoma, converging near a low pressure system over southern Oklahoma that should stay south of Interstate 40.
“Anywhere along and either side of that warm front this afternoon and evening would have higher potential, if a storm can get going and interact with that warm front area, that storm would have a higher potential to produce a tornado,” Smith said during a briefing Friday morning. “We do expect the main threat from the severe storms to be hail and wind, but tornadoes are certainly a possibility.”
The low pressure system could arrive in the Oklahoma City metro around 7 p.m.
Several severe thunderstorms were reported in southwest and north-central Oklahoma Friday afternoon, producing quarter-sized hail.

This latest threat comes just a few days after the Norman-based Storm Prediction Center issued a rare “Particularly Dangerous Situation,” warning of large hail, significant winds, and long-track devastating tornadoes. The twisters never quite materialized in the way meteorologists had feared, leading some to question the agency’s communication efforts.
