MESOSCALE DISCUSSION 0775
NWS STORM PREDICTION CENTER NORMAN OK
1000 PM CDT SAT MAY 28 2016

AREAS AFFECTED...PORTIONS OF WRN AND CENTRAL TX

CONCERNING...SEVERE THUNDERSTORM WATCH 226...

VALID 290300Z - 290400Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 226
CONTINUES.

SUMMARY...LOCAL/ISOLATED SEVERE RISK CONTINUES IN SOME AREAS IN AND
CLOSE TO THE WW.  LOCAL EXTENSION OF PORTIONS OF THE WW IN TIME/AREA
MAY NEED CONSIDERATION AS WW IS SCHEDULED TO EXPIRE AT 29/04Z.

DISCUSSION...LATEST RADAR IMAGERY SHOWS SCATTERED STRONG/ISOLATED
SEVERE STORMS ONGOING ATTM -- ACROSS PORTIONS OF CENTRAL TX NW OF
SAT...AND ALSO IN AREAS JUST N AND NW OF THE CURRENT WW INTO WRN AND
NRN TX.  THE STORMS ARE BEING MAINTAINED BY A COMBINATION OF AMPLE
INSTABILITY AND LOW-LEVEL WARM ADVECTION -- WHICH IS INCREASING IN
CONJUNCTION WITH A GRADUALLY STRENGTHENING SELY LOW-LEVEL JET PER
AREA VWPS.  WHILE THE WARM ADVECTION MAY ALLOW STORMS TO CONTINUE --
OR EVEN INCREASE IN COVERAGE LOCALLY...WEAK RIDGING ALOFT AND A
GRADUAL/FORECAST DECREASE IN STRENGTH OF THE MID-LEVEL FLOW SUGGESTS
ONLY MARGINAL SEVERE RISK TO PERSIST BEYOND SCHEDULED WW EXPIRATION
-- LARGELY IN THE FORM OF MARGINALLY SEVERE HAIL.  GIVEN THIS...NEW
WW ISSUANCE APPEARS LIKELY TO BE UNNECESSARY...THOUGH EXTENSIONS OF
THE WW IN TIME/AREA MAY BE CONSIDERED LOCALLY.
