.UPDATE...
CONCERNING SEVERE THUNDERSTORM WATCH 150...
WILL EXTEND THE SEVERE THUNDERSTORM WATCH FOR CRANE...PECOS...

.DISCUSSION...
STRONG TO SEVERE THUNDERSTORMS CONTINUE TO DEVELOP ALONG/AHEAD OF
A SLOW MOVING COLD FRONT SLIDING ACROSS THE SOUTHERN PERMIAN
BASIN. CONVERGENCE ALONG THIS FRONT AND MODEST INSTABILITY
/CAPE VALUES TO 1000 J/KG/ HAVE COMBINED TO CONTINUE TO PRODUCE
SEVERE WEATHER AS PER RECENT SPOTTER REPORTS OF GOLF BALL SIZE
HAIL AND THUNDERSTORM OUTFLOW WIND GUSTS OVER 60 MPH. THE
POTENTIAL REMAINS FOR THIS MCS THUNDERSTORM CLUSTER TO CONTINUE
SOUTHWARD INTO PECOS AND TERRELL COUNTIES OVER THE NEXT TWO HOURS
BEFORE WEAKENING.
