DENVER - Flights are resuming at Denver International Airport after severe thunderstorms and a tornado warning forced planes to stay on the ground.Delays of about an hour and a half were reported Wednesday afternoon after a series of severe storms brought hail and strong winds to the area.

Some flights were diverted to Colorado Springs and Grand Junction, and they're slowly returning to Denver.

At least one tornado touched down in the town of Watkins, southeast of the airport, but no damage or injuries were reported.

Hail the size of ping pong balls sent pedestrians running for cover in Colorado Springs, and cars slid on the hail on Interstate 70 in Aurora.

Denver police reported as much as 5 inches of hail on the ground in some parts of town, bring what looked like a wintertime

Officials used snow plows to clear the hail from the main airport access road.

Sometimes it takes teamwork! #cowx #hail #towerroad
