... NWS damage survey for the 4/26/15 tornadoes...

Supercell thunderstorms developed just south of Interstate 20 across
Eastland and Comanche counties... and moved east-northeast roughly
following the shape of Interstate 20 west of Interstate 35 to the
Interstate 35w corridor. These supercells produced very large hail
and several EF-0 tornadoes from Sunday afternoon through the late
evening hours of the day. The tornadoes primarily occurred in
sparsely populated areas... primarily damaging trees and producing
light damage to residences and businesses in their path. One of
the most notable facts of the evolution of this event was the fact
that one of the supercells became nearly stationary over Johnson
County for 2 to 3 hours. This nearly stationary storm produced 4
tornadoes as its updraft cycled over southern Johnson County. The
storm also produced a swath of straight line wind damage from
fisherman's Paradise in far southwest Johnson County to the
northeast near Rio Vista. The most destructive aspect of this storm
was likely the flash flooding it produced as this nearly stationary
storm dumped over 6 inches of rain over large portions of central
and eastern Johnson County. Many County roads across Johnson
County remained closed during the damage survey on Monday due to
the widespread flooding that began Sunday evening. There were
no serious injuries and no fatalities reported during this severe
weather event.
