The Dallas-Fort Worth area was hit with severe storms Tuesday that spawned an EF-1 tornado in Irving and, meteorologists confirmed Wednesday another EF-1 tornado and wind damage in Wise County. Residents in Irving — where the weather service confirmed a tornado touched down on Pioneer Drive between North MacArthur and North O’Connor boulevards — reported the wind shaking their homes.

In Irving, a tornado with winds up to 110 mph struck, while another touched down in the 16,000-resident city of Ada, Oklahoma, according to preliminary information from the National Weather Service. There were also two tornadoes in Louisiana’s northern Caddo Parish and at least five in eastern Oklahoma.

Tornado season is in spring because this is the time when air temperatures clash. The warm Gulf of Mexico winds mix with the cooler north winds, creating unstable atmospheric conditions which spawn tornadoes. The warmer it gets, the more likely it is for severe storms to form.
