News 9 Storm Trackers Val & Amy Castor followed an Oklahoma storm into Kansas, where it produced another tornado and knocked over a tractor-trailer.

Val rushed out of his storm truck to help free the driver from his cab.

Friday night's severe weather was only Round 1 of several expected over the next few days. News 9 Chief Meteorologist David Payne says we can expect two waves of storms Saturday: one in the morning and a second in the late afternoon into the evening.

That first round produced a tornado earlier in the evening in Beaver County.
