Area forecast discussion, May 26, 2:36 AM CDT, 2 hours 11 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CORPUS CHRISTI TX 236 AM CDT THU MAY 26 2011 .DISCUSSION...UPDATED ZONES TO INCLUDE SEVERE THUNDERSTORM WATCH 378 FOR CALHOUN AND VICTORIA COUNTIES THROUGH 9 AM. && .PREV DISCUSSION... /ISSUED 112 AM CDT THU MAY 26 2011/ DISCUSSION...ADDED ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS OVER THE VICTORIA CROSSROADS REGION. SOME BACKBUILDING AS FAR WEST AS GONZALES COUNTY WILL ALLOW BEST CHANCES OF CONVECTION OVER GOLIAD AND VICTORIA COUNTIES. MID LEVEL TEMPS ARE COOLING WITH COLD POOL BEHIND THE CLUSTER OF UPSTREAM THUNDERSTORMS WITH CAP ERODING WITH CIN OF 100. ENOUGH FRONTAL CONVERGENCE AND LIFT MAY BE AVAILABLE IN CONCERT WITH UPSTREAM HISTORY OF HAIL WILL LEND TO ISOLD STRONG TO SEVERE THUNDERSTORMS OVER THE VCT CROSSROADS. PREV DISCUSSION... /ISSUED 1159 PM CDT WED MAY 25 2011/ DISCUSSION...SEE UPDATED AVIATION DISCUSSION. AVIATION...OVERALL THINK THE CAP WILL HOLD TONIGHT KEEPING TSTMS JUST NE OF VCT AREA...BUT MAY BE CLOSE AND WILL HAVE TO BE WATCHED. WEAK FRONTAL BOUNDARY WILL MOVE INTO THE REGION OVERNIGHT STALLING NEAR THE COAST. EXPECT SOME LOW STRATUS WITH MVFR-IFR CIGS AS THE BOUNDARY DRAWS NEAR. THIS FRONT MAY POOL ENOUGH MOISTURE TO PROVIDE ISOLD TSTMS ACROSS INLAND AREAS ON THU (ALI- VCT)...BUT CHCS TO LOW FOR MENTION IN TAFS. OVERALL WILL SHOW CONDITIONS IMPROVING TO VFR BY NOON WITH VFR PREVAILING FOR REMAINDER OF THE DAY. PREV DISCUSSION... /ISSUED 1114 PM CDT WED MAY 25 2011/ DISCUSSION...SEVERE STORMS TO THE NORTH ARE GREATLY BENEFITING FROM SOME SIG H7 COOLING ASSOC W/ THE LARGE UPR LOW TO THE NORTH. IN FACT THE STORMS SEEM TO BE LINED UP ALONG A SUDO H7 FRONT ANALYSIS BY THE RUC AT 03Z WHERE THE TSTMS ARE LOCATED. DESPITE THE H7 COOLING IN THE COASTAL BEND...THINK THE CIN WILL REMAIN HIGH ENOUGH THAT THE STORMS TO THE NORTH WILL REMAIN NE OF THE VCT AREA. THAT BEING SAID...THE 00Z NAM12 SHOWS AN ELEVATED MOIST AND VERY UNSTABLE LAYER ABOVE H9 THAT MIGHT ALLOW STORMS TO BECOME ELEVATED ABOVE THE NEGATIVE ENERGY IN THE LOWEST 100 MB. WILL CONTINUE TO LEAVE POPS OUT...BUT THIS WILL HAVE TO BE WATCHED CLOSE. ALSO...THE NAM12 SHOWS THE FRONT NOW REACHING THE COAST AND SHOWS POTENTIAL FOR ISOLD CONVECTION ALONG THIS BOUNDARY WITH HEATING AS IT INDICATES THE CAP WASHES OUT COMPLETELY ALONG A NARROW BAND NEAR THE FRONT AND SEA BREEZE. BASED ON THIS WE MAY NEED TO INCLUDE SOME LOW POPS FOR THU...BUT WILL LET THE MIDNIGHT SHIFT DECIDE. PREV DISCUSSION... /ISSUED 349 PM CDT WED MAY 25 2011/ SHORT TERM (TONIGHT THROUGH THURSDAY NIGHT)...SVRL OF THE MODELS CONTINUED TO SHOW THE POSSIBILITY OF ISOLATED CONVECTION DEVELOPING THIS EVENING ALONG THE DRYLINE/COLD FRONT TO OUR NORTH. BLV THE STRONG CAP...LIMITED MOISTURE AND INSUFFICIENT MOISTURE WL LKLY KEEP OUR CWA DRY TNT...DESPITE THE FRONTAL BOUNDARY STALLING NEAR THE VCT AREA BY SUNRISE. WL GO WITH SILENT 10% POPS FOR NOW FOR THE NERN CWA. OTHERWISE...A VERY WARM AND CONTINUED DRY FCST WL STILL HOLD THROUGH THE REMAINDER OF THE FCST. THE WINDS WL CONTINUE TO WEAKEN THROUGH THURSDAY GIVEN THE PROXIMITY TO THE FRONT AND THE OVERALL WEAKENING GRADIENT. CONTINUED TO KEEP TEMPS GENERALLY 5 DEGS ABV CLIMO WITH A SLIGHT "COOLING" ON THURSDAY GIVEN THE MORE EASTERLY COMPONENT TO THE WIND. LONG TERM (FRIDAY THROUGH WEDNESDAY)...THE UPPER LEVEL RIDGE WILL BUILD OVER THE SOUTHEAST US OVER THE WEEKEND. AS A TROUGH DIGS INTO THE INTER-MOUNTAIN WEST ON SUNDAY...SURFACE CYCLOGENESIS OVER THE PLAINS WILL INCREASE THE PRESSURE GRADIENT ACROSS THE AREA. SE WINDS WILL INCREASE OVER THE WEEKEND...ESPECIALLY ON SUNDAY. 850H TEMPS AROUND 22C WILL EFFECTIVELY CAP THE ATMOSPHERE SO NO SHOWERS AND THUNDERSTORMS ARE EXPECTED. THE ECMWF SOLN SHOWS A TUTT LOW DEVELOPING OVER THE GULF EARLY NEXT WEEK...THEN GRADUALLY MOVES THIS LOW WESTWARD THROUGH WEDNESDAY. THE GFS ALSO SHOWS THIS FEATURE...ALTHOUGH IT IS MUCH WEAKER. BOTH MODELS AGREE ON KEEPING THIS UPPER LOW TO THE EAST OF THE CWA. WITH THE UPPER LEVEL RIDGE STRENGTHENING AND BUILDING TO THE NORTH OF THE AREA ON TUESDAY...SE FLOW WILL PREVAIL IN THE LOW AND MID LEVELS. TEMPERATURES COOL IN THE 850-700H LAYER BY TUESDAY-WEDNESDAY...WHICH MAY INCREASE CONVECTION CHANCES ACROSS THE AREA BY DECREASING THE CIN. HOWEVER THE PROXIMITY OF THE UPPER LEVEL RIDGE ALONG WITH A LACK OF SIGNIFICANT FORCING MECHANISM WILL HINDER STORM CHANCES...AND ONLY 10 POPS ARE INCLUDED AT THIS POINT FOR TUESDAY-WEDNESDAY. OTHERWISE CONTINUED HOT AND HUMID CONDITIONS WILL PREVAIL THROUGH THE EXTENDED. MARINE...CONDITIONS WL ACTUALLY REMAIN BELOW SMALL CRAFT ADVY CONDITIONS THROUGH THURSDAY NIGHT DUE TO THE AFOREMENTIONED FRONTAL BOUNDARY STALLING ACROSS THE NERN CWA LATER TNT.
