TULSA, OK -- The eastern half of Oklahoma is now under a tornado watch until 9 p.m. The National Weather Service issued the watch Thursday afternoon.
There is a good chance for severe weather across northeastern Oklahoma this afternoon and evening.
News On 6 chief meteorologist Travis Meyer says a strong storm system is moving out of the Rockies and headed east.
The tornado watch covers everything east of I-35.
The number of storms may be few, but some of the storms could develop to severe status as the system reaches the warm moist air over northeastern Oklahoma.
Once this system passes, Meyer says Friday will be cool and breezy with warm and mild conditions expected on Saturday.
Sunday, another system will over northeast Oklahoma and it is expected to produce rain and a chance for some thunderstorms.
