TULSA, Oklahoma - Heavy rain and lightning hammered northeastern Oklahoma as commuters started home from work. The National Weather Service let severe thunderstorm warnings expire at 6:45 p.m. Tuesday. 

There are still alerts for flooding. 

Storms developed in central Oklahoma and moved northeast around the rush hour. The storms could produce 60 mph winds, heavy lightning and nickel-sized hail as they moves through Green Country.

Overnight tonight will be fairly quiet, some lingering showers will be possible into tomorrow morning. Tomorrow afternoon, scattered showers and storms will break out. 

A storm system will move through and along a cool front, we’ll have a line of strong to severe storms move from the northwest to the southeast tomorrow night. There’s the likelihood that some of those storms will also be strong to severe.

By Thursday morning, showers and storms will be in southeastern Oklahoma and we’ll have quiet weather for most of Green Country during the day. 

The weather pattern will remain active through the weekend. Dew points staying in the “miserable” range and afternoon heat index values will remain in the upper 90s, near 100. A more “typical” August pattern returns by the start of next week and it should quiet down for a few days at least.
