August 7-8, 2013 Severe Storms and Flooding
 

A nearly ideal setup for widespread rain and thunderstorms across the Panhandles evolved on August 7 and 8.  Aloft, a series of shortwave troughs moved across the area, providing adequate large scale lift.  At the surface, a stationary front and multiple outflow boundaries also aided in low-level lifting.  With very moist air in place, the amount of lifting easily triggered multiple rounds of convection each afternoon and evening.  Many of the same areas were hit repeatedly, which led to isolated flooding in some spots.

On Wednesday, August 7, severe thunderstorms mainly targeted the Oklahoma Panhandle and the northwestern Texas Panhandle.  Many of the storms produced damaging wind gusts, including a 68 mph wind gust near Goodwell, OK.  Some of the storms initially produced very large hail, including up to baseball size north of Boise City, OK that caused damage to some vehicles.  Additionally, one supercell thunderstorm produced a brief EF-0 tornado near Turpin, OK.  As the storms moved over the same areas, very heavy rain caused flash flooding in Guymon and Beaver, OK. 

On Thursday, August 8, severe thunderstorms were more prevalent across the central and southern Texas Panhandle.  These storms produced a wind gust of 77 mph near Hereford, TX (West Texas Mesonet summary) and golf ball size hail near Fritch, TX.  Although flooding was not as severe as it was the previous night, some street flooding still occurred in Perryton and Shamrock, TX.
