NWS San Angelo, TX wrote its last area forecast discussion before the first event at May 23, 2:12 PM CST, 3 hours 18 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN ANGELO TX 312 PM CDT THU MAY 23 2013 .SHORT TERM... OBVIOUS ISSUE IN THE SHORT TERM IS POTENTIAL FOR SEVERE WEATHER TONIGHT. A TORNADO WATCH IS IN EFFECT FOR THE BIG COUNTRY AREA...WITH A SEVERE THUNDERSTORM WATCH IN EFFECT FOR MOST OF THE CONCHO VALLEY...AND NORTHERN EDWARDS PLATEAU. SEVERE THUNDERSTORMS HAVE ALREADY DEVELOPED WEST AND NORTHWEST OF THE AREA...WITH ONE CLUSTER NEAR THE DAVIS MOUNTAINS...AND A MORE INTENSE AREA SOUTHWEST OF CHILDRESS WHERE TORNADO WARNINGS HAVE ALREADY BEEN ISSUED. AN OUTFLOW BOUNDARY IS CURRENTLY POSITIONED ACROSS THE BIG COUNTRY FROM THE NORTHWEST TO SOUTHEAST. THUNDERSTORMS ARE BEGINNING TO DEVELOP ALONG THIS BOUNDARY TO THE SOUTHEAST TOWARD OUR BIG COUNTRY COUNTIES. WHILE WIND SHEAR DECREASES IN MAGNITUDE AS ONE MOVES SOUTHEAST AWAY FROM THE INITIAL CONVECTION...INSTABILITY ACTUALLY INCREASES. SO...WHILE STORMS MAY NOT BE TAPPING INTO THE BEST SHEAR AS THEY ENTER OUR AREA...THEY WILL HAVE PLENTY OF INSTABILITY TO WORK WITH AS SFC BASED CAPE VALUES RANGE BETWEEN 3500 AND 4500 J/KG. FARTHER SOUTH...CAPE VALUES FROM THE SOUTHERN BIG COUNTRY INTO THE CONCHO VALLEY AND NORTHERN EDWARDS PLATEAU RANGE FROM 4500 TO 5000 J/KG...SO THERE IS EVEN MORE INSTABILITY TO TAP INTO. HOWEVER...THE CAP STRENGTHENS AS ONE MOVES EAST...SO THERE IS SOME QUESTION AS TO WHETHER OR NOT STORMS WILL BE ABLE TO DEVELOP. IN ADDITION...SHEAR ALSO WEAKENS...SO STORMS WILL LIKELY BE ABLE TO ROTATE AS THEY INITIALLY DEVELOP...SUSTAINED ORGANIZATION IS QUESTIONABLE. AS THE ACTIVITY DEVELOPS INTO THE EVENING HOURS...UPSCALE DEVELOPMENT INTO CLUSTERS OF STORMS OR WEAKLY ORGANIZED MCS/S IS EXPECTED...AS THE STORMS MOVE EAST TO SOUTHEAST. ON FRIDAY...MODELS ARE SUGGESTING THAT A WEAKNESS WILL DEVELOP WITHIN THE RIDGE AND MOVE ACROSS THE AREA. WITH THAT IN MIND...AND THE FACT THAT WE WILL CONTINUE TO HAVE AMPLE MOISTURE AROUND...HAVE KEPT CHANCE POPS IN THE FORECAST FOR THE AREA. ALSO...WITH THE ADDITIONAL CLOUD COVER AND POSSIBLE RAINFALL DISRUPTING THINGS...HAVE KEPT TEMPERATURES IN THE INHERITED UPPER 80S FOR THE AREA. 20 .LONG TERM... THE CONCERNS IN THE EXTENDED FORECAST ARE THE CONTINUED CHANCE OF SHOWERS AND THUNDERSTORMS SATURDAY...FOLLOWED BY POSSIBLY ANOTHER CHANCE OF PRECIPITATION AROUND THE MIDDLE OF NEXT WEEK. SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED ACROSS MUCH OF THE AREA TOMORROW NIGHT AS A WEAKNESS IN THE RIDGE IS LOCATED OVER WEST CENTRAL TEXAS. EXACTLY WHERE STORMS DEVELOP WILL BE DEPENDENT ON ANY OUTFLOW BOUNDARIES THAT ARE LEFTOVER FROM CONVECTION THAT DEVELOPS TONIGHT. PRECIPITABLE WATER VALUES WILL BE OVER 1.5 INCHES ACROSS A GOOD PORTION OF THE REGION. THIS COMBINED WITH SLOW STORM MOTION COULD RESULT IN LOCALLY HEAVY RAINFALL. A FEW SHOWERS AND THUNDERSTORMS MAY LINGER INTO SUNDAY...BUT FOR NOW I HAVE LEFT THE FORECAST DRY AS THE MAIN FOCUS HAS BEEN ON THE FIRST 48 HOURS. DRIER CONDITIONS CAN BE EXPECTED FOR THE FIRST PART OF NEXT WEEK...WITH NEAR NORMAL TEMPERATURES. MODELS INDICATE THE NEXT UPPER LEVEL TROUGH MOVING ASHORE THE WEST COAST TUESDAY...THEN APPROACHING WEST CENTRAL TEXAS WEDNESDAY OR THURSDAY OF NEXT WEEK. MODEL DIFFERENCES IN TIMING AND STRENGTH OF THIS UPPER LEVEL TROUGH CONTINUE...SO FOR NOW I HAVE KEPT POPS JUST BELOW 20 PERCENT. POPS MAY NEED TO BE INTRODUCED ON FUTURE SHIFTS IF MODELS CONTINUE TO INDICATE THE APPROACH OF THIS NEXT STORM SYSTEM AROUND THE MIDDLE OF NEXT WEEK. DANIELS && .PRELIMINARY POINT TEMPS/POPS...
