NWS San Angelo, TX wrote its last area forecast discussion before the first event at Apr 13, 1:30 PM CST, 4 hours 36 minutes earlier.
WEST CENTRAL TEXAS FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN ANGELO TX 230 PM CDT SAT APR 13 2002 ...FORECAST CHALLENGE WILL BE CONVECTIVE POTENTIAL LATER THIS AFTERNOON AND EVENING... .SHORT TERM...CLOUD CANOPY CURRENTLY INHIBITING HEATING ACROSS MUCH OF THE AREA AS SHOWN BY THE LAPS STILL SHOWING -200 TO -300 J/KG THUNDERSTORM POTENTIAL LOOKS TO BE DELAYED UNTIL WE CAN GET A LITTLE MORE HEATING AND A COUPLE OF SHORT WAVES TO MOVE OVER SO THAT THE CAP CAN WEAKEN. AN OUTFLOW BOUNDARY THAT WAS GENERATED BY CONVECTION THIS MORNING HAS MOVED ACROSS MAJORITY OF THE FORECAST AREA THIS MORNING AND IS CURRENTLY JUST SOUTH OF SJT. THIS BOUNDARY IS SLOWING AND SHOULD BECOME STATIONARY ACROSS SOUTHERN PORTIONS OF THE FORECAST AREA AND MAY HELP TO FOCUS SOME CONVECTIVE ACTIVITY LATER THIS EVENING. .SHORT TERM...BELIEVE THAT THERE WILL BE TWO AREAS WHERE BETTER CONVECTIVE POTENTIAL EXIST. ONE OVER THE BIG COUNTRY IN AN AREA NEAR THE STRONGEST WAVE. THUNDERSTORMS SHOULD FIRE LATER THIS AFTERNOON NORTHWEST OF THE BIG COUNTRY AND MOVE IN THIS EVENING. SEVERE POTENTIAL WILL HINGE ON IF CONVECTIVE DEBRIS CAN GET OUT OF THE AREA TO ALLOW ENOUGH HEATING TO BREAK THE CAP. IF THIS DOES NOT OCCUR...THEN A FEW ELEVATED SEVERE THUNDERSTORMS POSSIBLE WITH 50 TO 60 KT SPEED MAX COMING INTO THE AREA. OTHER MAIN AREA WILL BE FROM THE EDWARDS PLATEAU OVER TO THE NORTHWEST HILL COUNTRY. THIS WILL BE FROM ANOTHER SHORT WAVE THAT SHOULD INITIATE CONVECTION ALONG THE DRY LINE THIS AFTERNOON WEST OF THE FORECAST WHERE CURRENTLY LAPS ANALYSIS AND SATELLITE INDICATES CAP IS BEGINNING TO ERODE DUE TO MORE SOLAR. THESE THUNDERSTORMS WILL RUN ALONG OUTFLOW BOUNDARY FROM LAST NIGHTS CONVECTION THAT WILL BECOME NEARLY STATIONARY ACROSS THE SOUTHERN COUNTIES. ALL THUNDERSTORMS SHOULD MOVE EAST OR DISSIPATE BY MIDNIGHT. .LONG TERM...THINGS BEGIN TO DRY OUT SUNDAY AS AREA IS IN BETWEEN SYSTEMS STILL A VERY SLIGHT CHANCE OF SOME SHOWERS ACROSS THE SOUTHEASTERN ZONES...BUT WILL PROBABLY LEAVE OUT FOR NOW. DEW POINTS BEGIN TO RECOVER SOME SUNDAY NIGHT INTO MONDAY MORNING. UPPER LOW OVER BAJA WILL GRADUALLY OPEN UP AND MOVE SLOWLY NORTHEAST THROUGH MONDAY. THIS APPEARS THAT IT WILL BE ENOUGH TO ACTIVATE THE DRY LINE MONDAY AFTERNOON...THEREFORE WILL INTRODUCE A SLIGHT CHANCE INTO THE FORECAST FOR EXTREME WESTERN PORTIONS OF FORECAST AREA. THIS WILL LINGER INTO THE EVENING BEFORE DISSIPATING. SOME INDICATIONS THAT THIS COULD OCCUR AGAIN TUESDAY...BUT WILL NOT GO OVERBOARD AT THIS POINT. .EXTENDED...THINGS REALLY DRY OUT FOR THE AREA THROUGH THURSDAY AS ZONAL FLOW TAKES OVER. A DEVELOPING TROUGH OVER THE WEST WILL MOVE INTO THE AREA ON FRIDAY THAT MAY GIVE US A CHANCE OF THUNDERSTORMS CONTINUING INTO SATURDAY ACROSS THE EASTERN COUNTIES.

A MOIST AND UNSTABLE ATMOSPHERE CONTINUES ACROSS WEST CENTRAL TEXAS. BUT SO FAR TODAY...CONSIDERABLE CLOUD COVER HAS REALLY LIMITED SURFACE HEATING. AS A RESULT...THE STRONG CAP HAS INHIBITED SURFACE BASED CONVECTION. THERE HAS BEEN SOME ELEVATED SHOWERS AND THUNDERSTORMS NEAR AND JUST NORTH OF A SOUTHWARD SINKING OUTFLOW BOUNDARY. THIS OUTFLOW BOUNDARY EXTENDED FROM STERLING CITY...TO BALLINGER AND COLEMAN AT 1 PM...AND MAY REACH SAN ANGELO AND BROWNWOOD BEFORE STALLING AROUND 2 PM OR SO. BASED ON CURRENT TRENDS...IT APPEARS THUNDERSTORMS WILL NOT DEVELOP UNTIL AFTER 4 PM...WHEN THE CAP WILL FINALLY WEAKEN WITH THE APPROACH OF AN UPPER LEVEL DISTURBANCE. GIVEN THE AMOUNT OF INSTABILITY PRESENT...LARGE HAIL AND DAMAGING WINDS WILL BE THE PRIMARY THREATS. HOWEVER...THERE IS SUFFICIENT WIND SHEAR THROUGHOUT THE ATMOSPHERE TO ALLOW THE DEVELOPMENT OF A FEW TORNADOES AS WELL. SPOTTER ACTIVATION MAY BE REQUIRED LATER THIS AFTERNOON. FOR ADDITIONAL INFORMATION PLEASE SEE STATEMENTS AND OUTLOOKS FROM NATIONAL WEATHER SERVICE OFFICES ACROSS TEXAS...OKLAHOMA...AND NEW MEXICO.
