   MESOSCALE DISCUSSION 0377
   NWS STORM PREDICTION CENTER NORMAN OK
   0201 AM CDT WED APR 13 2016

   AREAS AFFECTED...SE TX

   CONCERNING...SEVERE THUNDERSTORM WATCH 88...

   VALID 130701Z - 130900Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 88
   CONTINUES.

   SUMMARY...BOWING SQLN WITH A DMGG WIND THREAT EXPECTED TO CONTINUE E
   ACROSS THE HOUSTON-GALVESTON AREA TO THE UPPER TEXAS GULF
   CST...WHILE NEW STORMS FORM ALONG THE CST AND JUST OFFSHORE.

   DISCUSSION...BOWING SQLN NOW OVER THE HOUSTON METRO IS EXPECTED
   CONTINUE MOVING E AT ABOUT 45 KTS. STRONGEST NEW STORM DEVELOPMENT
   IN THE PAST HOUR HAS BEEN ON SRN END OF SYSTEM...WHILE CONVECTION ON
   NRN END /OVER HARRIS CNTY/ HAS SOMEWHAT WEAKENED. THESE
   OBSERVATIONS...COUPLED WITH LATEST SFC ANALYSIS AND EARLIER RAOB
   DEPLOYED BY THE UNIV OF HOUSTON...SUGGEST THAT THE SQLN IS SOMEWHAT
   ELEVATED. NEVERTHELESS...GIVEN FAST FORWARD SPEED OF MOVEMENT AND
   STRENGTH OF UPDRAFTS /PER RADAR REFLECTIVITY/...POTENTIAL WILL EXIST
   FOR LOCALLY DMGG WIND/MARGINALLY SVR HAIL.

   OTHER STORMS ARE FORMING ATTM ALONG AND JUST OFF THE MID AND UPR TX
   GULF CST. THESE ARE DEVELOPING ALONG SWLY LLJ THAT LIKELY IS
   STRENGTHENING IN RESPONSE TO THE CONTINUED EWD MOVEMENT OF W TX UPR
   TROUGH AND LOCALIZED STRENGTHENING OF SLY FLOW AHEAD OF HOU SQLN.
   THE CSTL STORMS LIKELY ARE ALSO SLIGHTLY ELEVATED...BUT PERHAPS LESS
   SO THAN THOSE IN THE SQLN. GIVEN MOISTURE-RICH INFLOW /PW AROUND
   1.75 IN/ AND CONSIDERABLE NEAR-SFC DIRECTIONAL SHEAR...A NON-ZERO
   TORNADO RISK COULD EXIST WITH ANY LONGER-LIVED/MORE DISCRETE
   UPDRAFTS.  A NON-ZERO TORNADO THREAT ALSO MAY DEVELOP ALONG TRAILING
   PART OF SQLN...AS NEW STORMS CONTINUE TO BACK-BUILD ALONG IT. 40-50
   KT CLOUD-LAYER SHEAR COULD YIELD AND EMBEDDED SUPERCELL OR
   TWO...WITH DMGG WIND AND POSSIBLY A TORNADO...AS THE LINE NEARS THE
   CST.
