Mar 18, 2008
Storms developed along a dry line which moved into north Texas during the afternoon hours on the 18th. Rich Gulf moisture and ample instability helped the storms develop further as they encountered a warm front to the east. At least one tornado touched down and more than a thousand flights were cancelled at Dallas/Fort Worth Airport as numerous storms moved through the metroplex.
