AREAS AFFECTED...WRN OK...NW TX

CONCERNING...TORNADO WATCH 214...

VALID 270046Z - 270145Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 214 CONTINUES.

SUMMARY...ALL SEVERE HAZARDS REMAIN POSSIBLE ACROSS WRN OK FOR THE
NEXT FEW HOURS.

DISCUSSION...REGIONAL RADAR IMAGERY HAS SHOWN INCREASING CONVECTIVE
ACTIVITY OVER THE PAST HOUR AS UPDRAFTS DEVELOPING ON THE DRYLINE IN
THE FAR ERN TX PANHANDLE HAVE FINALLY PERSISTED LONG ENOUGH FOR
LIGHTNING PRODUCTION. ACTIVITY ACROSS NW TX HAS INTENSIFIED AS A
RESULT OF INTERACTION WITH A WWD MOVING OUTFLOW BOUNDARY.
HOWEVER...RECENT TRENDS SUGGEST THESE STORMS ARE LIKELY ELEVATED.

DEWPOINTS ACROSS WRN OK HAVE REMAINED HIGHER THAN AREAS TO THE E OR
W WITH RECENT MESOANALYSIS SUGGESTING THIS REGION REMAINS FREE OF
CINH. ADDITIONALLY...SELY WINDS OVER THE AREA HAVE INCREASED OVER
THE PAST HOUR AND TEMPERATURES REMAIN IN THE MID 80S. AS SUCH...THE
OVERALL ENVIRONMENT IS EXPECTED TO REMAIN FAVORABLE FOR ALL SEVERE
HAZARDS FOR THE NEXT FEW HOURS. ONE NEGATIVE FACTOR FOR PERSISTENT
UPDRAFTS IS SUBSIDENCE RESULTING FROM THE LARGE CONVECTIVE COMPLEX
ACROSS SE TX. LONG LOOP VISIBLE SATELLITE IMAGERY SHOWS CLOUDS
ACROSS CNTRL OK QUICKLY CLEARING AS A RESULT OF THIS SUBSIDENCE THIS
AFTERNOON AND EVENING.
