COMPOSITE OUTFLOW BOUNDARY/COLD FRONT. VWP DATA FROM KPUX SHOW
PRONOUNCED VEERING IN THE LOWEST 3 KM, SUGGESTING THAT ASCENT OVER

THUNDERSTORM DEVELOPMENT IN THE NEAR TERM (NEXT 1-2 HOURS) BEFORE
THE BOUNDARY BECOMES INCREASINGLY DISPLACED FROM THE BETTER BUOYANCY

45-50 KNOTS WILL CONTINUE TO PROMOTE SUPERCELLS WITH AN ATTENDANT
THREAT FOR LARGE HAIL, POSSIBLY AS LARGE AS 1.5 TO 2 INCHES IN
DIAMETER. DOWNSTREAM PROPAGATION EASTWARD IS POSSIBLE AS CONTINUED
TRAINING PROMOTES STORM INTERACTIONS/UPSCALE GROWTH INTO A HIGHER
MLCAPE ENVIRONMENT TO THE EAST, BUT EXACT CONVECTIVE EVOLUTION
REMAINS SOMEWHAT UNCERTAIN BEYOND THE NEXT COUPLE OF HOURS.
