   NWS STORM PREDICTION CENTER NORMAN OK
   0702 AM CST TUE JAN 08 2013
   
   AREAS AFFECTED...UPPER TX COAST
   
   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 
   
   VALID 081302Z - 081430Z
   
   PROBABILITY OF WATCH ISSUANCE...5 PERCENT
   
   SUMMARY...A NEAR-SHORE SEVERE/WATERSPOUT POTENTIAL COULD OCCUR ALONG
   THE UPPER TX COAST THIS MORNING...ALTHOUGH ANY SUCH POTENTIAL SHOULD
   REMAIN VERY ISOLATED /AND OF SHORT DURATION/ THIS MORNING. NO WATCH
   IS ANTICIPATED.
   
   DISCUSSION...RECENT RADAR IMAGERY /SINCE 1230Z/ IS INDICATIVE OF A
   STORM WITH UPDRAFT ROTATION JUST OFF THE UPPER TX COAST...SOUTHWEST
   OF THE FREEPORT TX VICINITY AS OF 1250Z. THIS TSTM IS LIKELY
   OCCURRING VERY NEAR/PERHAPS JUST A BIT NORTH OF A SHARPENING WARM
   FRONT THAT DEMARCATES RELATIVELY COOL CONTINENTAL TRAJECTORIES
   INLAND AND A MORE MOISTURE-RICH AIR MASS /60S F SURFACE DEWPOINTS/
   OVER THE WESTERN GULF OF MEXICO. WHILE LOW-LEVEL/DEEP LAYER SHEAR IS
   MORE THAN ADEQUATE FOR SUPERCELLS PER A LONG-CURVING HODOGRAPH PER
   THE HOUSTON WSR-88D VWP...THIS STORM SHOULD TEND TO REMAIN OFFSHORE
   FAVORING THE NEARLY-STALLED SURFACE BOUNDARY AND/OR BECOME
   INCREASINGLY ELEVATED TOWARD THE COAST. WHILE A NEAR-SHORE SEVERE
   POTENTIAL CANNOT BE RULED OUT INCLUDING THE POSSIBILITY OF
   WATERSPOUTS...IT SHOULD REMAIN MARGINAL/ISOLATED.
