A weak disturbance in broad west northwest flow in the mid and upper levels of the atmosphere, strong daytime heating and attendant atmospheric instability, sufficient moisture, a developing dryline, and moderate wind shear aided in several severe storms on May 5th.  One of the storms was able to produce a tornado in Roberts County Texas. No rating for the tornado as it was in open field, but it was estimated to be on the ground nearly 15 minutes, and may have been as wide as 500 yards at one point based on photographs.
