CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 211814Z - 211845Z

TORNADO WATCH WILL BE ISSUED SOON FOR PORTIONS OF CENTRAL/ERN OK.

THUNDERSTORMS ARE EXPECTED TO DEVELOP ALONG A DRY LINE WHICH
CURRENTLY EXTENDED FROM NWRN OK SEWD TO JUST WEST OF OKC AND THEN
SWD TO JUST EAST OF FTW.  TCU IS TRYING TO DEVELOP WITHIN THE
STRONGLY SHEARED ENVIRONMENT ALONG THE DRY LINE PER VISUAL
OBSERVATION AT SPC.  SURFACE BASED CIN HAS DECREASED ALONG THIS
BOUNDARY...WITH ADDITIONAL SURFACE HEATING EXPECTED TO AID IN
DESTABILIZATION WITHIN NARROW MOIST AXIS LOCATED ALONG/E OF DRY
LINE.  DEEP LAYER SHEAR VALUES WILL REMAIN MORE THAN SUFFICIENT FOR
SUPERCELLS...WHILE BACKED LOW LEVEL WINDS ALONG/E OF DRY LINE WILL
ENHANCE LOW LEVEL SHEAR FOR TORNADO THREAT.
