CONCERNING...SEVERE THUNDERSTORM WATCH 650...

VALID 170230Z - 170400Z

ISOLATED DAMAGING WIND GUSTS WILL REMAIN POSSIBLE...AS NEW

CLARK AND FAR ERN SAN BERNARDINO COUNTIES. ADDITIONALLY...LOCALLY
HEAVY RAINFALL IS POSSIBLE WHERE TWO OUTFLOW BOUNDARIES MERGE IN THE
VICINITY OF LAS VEGAS. THE OVERALL SEVERE THREAT MAY REMAIN
SUFFICIENTLY LOW THAT WW 650 COULD BE CANCELLED EARLY.

LATEST SFC/RADAR DATA CONTINUES TO SHOW OUTFLOW BOUNDARY FROM
EARLIER CONVECTION OVER NWRN AZ MOVING WWD ACROSS CLARK COUNTY NV
AND FAR ERN SAN BERNARDINO COUNTY CA. DESPITE WELL DEFINED CB/S ON
RECENT VISIBLE SATELLITE IMAGERY ON THE LEADING EDGE OF THE OUTFLOW
OVER CLARK COUNTY...WEAKENING RADAR TRENDS ALONG WITH DIURNAL LOSS
OF HEATING/STABILIZATION SHOULD LIMIT THE SEVERE THREAT TO ONLY
ISOLATED/BRIEF OCCURRENCES FOR THE NEXT HOUR OR SO. IF CURRENT
CONVECTIVE TRENDS CONTINUE THEN WW 650 MAY BE CANCELLED EARLY.
