...Though nearly a week has passed since the thunderstorms, (click here) meteorologist Pete Snyder said surveyors haven't finished assessing possible tornado-damaged areas. He said it's likely about dozen tornadoes touched down during the storms.
Tuesday's a squall line developed in northwest Texas and southwest Oklahoma, where it traveled into central Oklahoma and northeast Kansas before it moved into eastern Oklahoma and Arkansas.
Because of the breadth of these storms, as well as their strong straight line winds, meteorologists are having difficulties quantifying its damage and whether or not it came from tornadoes, Snyder said. 
“I’ve been here for about 17 years almost," Snyder said. "I’ve never seen this many of them with a system like this.”
Surveyors sent to locations to evaluate damage look at patterns — how debris is scattered or which directions trees fell — to determine if its tornado-damaged or not. From there, they look at the strength of damaged structures or trees to estimate wind speed and rate the tornado on the EF scale, Snyder said.
Snyder was unsure when the National Weather Service would have a complete list of the storm system's tornadoes, adding he was still receiving calls about new potential tornado-damaged areas Sunday.
