Dallas & Irving Tornado on Sunday, May 24, 2015

Many of you may have been awakened by the Tornado Warning in western Dallas/eastern Tarrant Counties early Sunday morning. The tornado sirens sounded across the warned area, and even in my area near the Grapevine/Southlake border. Fortunately the tornado in Irving dissipated as it moved north-northwest toward the residential areas of Carrollton.

As it turns out, the warning was a “good” warning (i.e., a warning that verified), because two tornadoes formed within the warned area after the warning was issued. The warning was issued at 2:27 am, seven minutes before tornadoes formed in Dallas and Irving (they formed at approximately the same time…2:34 am…from two distinct circulations).

Damage Survey Findings

The following is a paraphrased summary from the NWS damage survey.

→ Dallas/Farmers Branch Tornado

The first tornado began in the City of Dallas with damage to trees and power lines occurring near the intersection of Walnut Hill and Marsh. This tornado continued to the north-northwest and crossed over the LBJ Freeway at Josey Lane and moved into Farmers Branch, where an apartment complex suffered roof damage. Most of the damage in Dallas was EF-0, but the damage increased as the tornado moved into Farmers Branch. Some of the most notable damage in Farmers Branch included roof damage to a number of warehouse buildings near the intersection of Valwood Parkway and I-35E before dissipating near the Tommy Standridge Stadium Park (just inside the Carrollton City limits by about 1,000 feet).
