MESOSCALE DISCUSSION 0652
NWS STORM PREDICTION CENTER NORMAN OK
1013 AM CDT THU MAY 19 2016

AREAS AFFECTED...MIDDLE TX COASTAL PLAIN

CONCERNING...SEVERE THUNDERSTORM WATCH 182...

VALID 191513Z - 191645Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 182
CONTINUES.

SUMMARY...SEVERE STORMS MAY YET DEVELOP WITHIN THE EASTERN PART OF
WW 182 AS A CLUSTER PROGRESSES EAST AND PERHAPS ADDITIONAL STORMS
FORM SOUTH. ISOLATED WIND/HAIL SHOULD REMAIN THE PRIMARY THREATS.

DISCUSSION...A 35-KT EASTWARD-MOVING CLUSTER CENTERED OVER LIVE OAK
COUNTY HAS SHOWN AN INTENSIFICATION TREND IN INBOUND VELOCITIES OVER
THE PAST 20 MINUTES. THIS SUGGESTS POTENTIAL FOR STRONG TO ISOLATED
SEVERE WIND GUSTS MAY BE INCREASING AS THIS APPROACHES THE MIDDLE
COASTAL PLAIN GIVEN PRESENCE OF LOW-LEVEL EASTERLIES AND LOWER 70S
SURFACE DEW POINTS. FARTHER SOUTH...WEAK SHOWERS APPEAR TO BE
DEVELOPING NEAR THE CRP/BRO CWA BORDER. GIVEN SUBSTANTIAL VEERING OF
THE WIND PROFILES WITH HEIGHT /PER CRP VWP DATA/ AND MODERATE
BUOYANCY SAMPLED IN 12Z CRP RAOB /ALTHOUGH MUCH OF THIS WAS CONFINED
TO THE UPPER PORTION OF THE PROFILE WITH MODEST LOW-LEVEL LAPSE
RATES/...IT IS POSSIBLE THAT A STORM OR TWO MAY BECOME
SEMI-ORGANIZED WITH A RISK FOR SEVERE HAIL AND LOCALLY STRONG WINDS.
