Synopsis

This event took place in conjunction with both a dry line along the Caprock and weak cold front moving south across the Southern Panhandle during the afternoon hours.  As can be seen in the LAPS model loops below, moisture content and helicities were conducive to supporting heavy rains, hail, damaging winds, and a tornado.  At around 2030Z, a severe storm developed with an area encompassing northern Motley and southern Hall counties.  This cell was progressing northeast at 20 mph.  Another intriguing cell developed just northeast of the storm in southeastern Hall county which remained stationary throughout its life.  As the severe storm continued Northeast a severe storm warning was issued at 2039Z for Motley and Hall counties.

As the storm entered south eastern Hall county, the smaller cell remained stationary and was eventually engulfed by the severe storm at 2120Z.   The now single cell moved into Childress county, producing a tornado in SW Childress county.

The SPC outlook for this time period included a slight risk for severe weather with the border of the slight area just east of storm development.

The following loops contain both Lubbock and Frederick, OK radars (reflectivity and velocity data), and LAPS model analysis of various quantities. 

The reported tornado took place around 2125Z-2136Z.

NOTE:
  Frederick, OK radar was having communication problems at the time of this event.  Thus, Lubbock forecasters were unable to analyze most of the radar data from Frederick, OK available below for the time of the event.  Also, there is still missing data from the Frederick, OK during the reported tornado event and 8 bit data was not available.
