NWS San Angelo, TX wrote its last area forecast discussion before the first event at Apr 26, 11:30 PM CST, 30 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN ANGELO TX 1230 AM CDT MON APR 27 2009 .DISCUSSION... /SEE AVIATION SECTION FOR 06Z TAF DISCUSSION/ && .AVIATION... SCATTERED SHOWERS AND THUNDERSTORMS FROM SAN ANGELO TO JUNCTION AND BRADY AT 5Z WERE MOVING SLOWLY NORTHEAST TO EAST. EXPECT ACTIVITY TO CONTINUE THROUGH MONDAY MORNING AS UPPER SHORTWAVES MOVE ACROSS THE REGION. BEST CHANCE OF STORMS AFTER DAYBREAK WILL BE AT KABI. STRATUS HAS BEEN BROKEN UP BY STORMS THIS EVENING...BUT EXPECT MVFR CIGS TO REFORM. MAY SEE SOME LIGHT FOG AND IFR CIGS AT KSOA AND KJCT WHERE SIGNIFICANT RAINFALL AMOUNTS HAVE OCCURED. MVFR CIGS SHOULD INCREASE TO VFR MONDAY AFTERNOON. ALSO MENTIONED LLWS UNTIL 15Z. KDYS VAD WAS SHOWING 50 KTS AT THE SECOND GATE...WHILE KSJT RADAR WAS SHOWING ONLY 35 KTS. KSJT LOWER WINDS PROBABLY DUE TO STORMS AND EXPECT LLWS TO REDEVELOP ACROSS THE CWA...AS GFS MODEL HAS 40 KT 850MB WINDS. && .PREV DISCUSSION... /ISSUED 650 PM CDT SUN APR 26 2009/ DISCUSSION... /SEE AVIATION SECTION FOR 00Z TAF DISCUSSION/ AVIATION... SEVERE/POSSIBLY TORNADO STORM NEAR AND SOUTH OF OZONA MAY AFFECT KSOA SONORA AROUND 1Z. LARGE HAIL AND DAMAGING WINDS MAY BE POSSIBLE FOR 2 TO 4 HOURS AT KSOA. SCATTERED THUNDERSTORMS OTHERWISE POSSIBLE ACROSS MOST OF TAF SITES THROUGH THE NIGHT AS AN UPPER SHORTWAVE MOVES ACROSS. SOME SHOWERS AND THUNDERSTORMS MAY AFFECT EASTERN TAFS SITES IN THE MORNING HOURS AS IT MOVES EAST. OTHERWISE MVFR CIGS...RETURN THIS EVENING. PREV DISCUSSION... /ISSUED 210 PM CDT SUN APR 26 2009/ SHORT TERM... FOR THIS AFTERNOON AND TONIGHT... THERE IS A THREAT FOR SEVERE WEATHER AS AN UPPER TROUGH OVER THE WESTERN CONUS SHIFTS EASTWARD TODAY AND TONIGHT WITH A LEAD SHORTWAVE LIFTING OUT ACROSS THE CENTRAL AND NORTHERN PLAINS...AND A SHORTWAVE AND SPEED MAX MOVE THROUGH THE BASE OF THE TROUGH AND INTO TEXAS. CURRENT WATER VAPOR SHOWS WEAK SHORTWAVE DISTURBANCE MOVING INTO TEXAS FROM NEW MEXICO/MEXICO...THIS WILL HELP INITIATE THUNDERSTORMS THIS AFTERNOON ALONG AND EAST OF THE DRYLINE. THE DRY LINE IS EXPECTED TO EXTEND FROM THE EASTERN PANHANDLE TO THE BIG BEND REGION BY LATE THIS AFTERNOON. THE AIRMASS WILL DESTABILIZE THIS AFTERNOON WITH THE APPROACH OF A WEAK SHORTWAVE AND SHOULD SEE STRONGER AND INCREASED THUNDERSTORM COVERAGE...ESPECIALLY ACROSS THE WESTERN BIG COUNTRY AND CONCHO VALLEY...THESE STORMS WILL QUICKLY MOVE TO THE NORTHEAST INTO THE NORTHERN BIG COUNTRY. SPC HAS PLACED THE BIG COUNTRY IN A MODERATE RISK FOR SEVER THUNDERSTORMS. INITIALLY THE MAIN THREAT WITH THESE STORMS WILL BE LARGE HAIL...DAMAGING WINDS AND ISOLATED TORNADOES ...BUT BY LATE AFTERNOON/EARLY EVENING THE TORNADO THREAT INCREASES AS 45 TO 55 KNOT LLJ DEVELOPS ACROSS THE AREA. WITH A MOIST AIRMASS IN PLACE FLOODING MAY BECOME A THREAT AS HEAVY RAINFALL IS POSSIBLE. THIS SITUATION WILL NEED TO BE MONITORED. FOR TONIGHT INTO MONDAY MORNING...THE COMBINATION OF THE LLJ AND A SHORTWAVE MOVING INTO THE AREA WILL MAKE ADDITIONAL THUNDERSTORMS DEVELOPMENT POSSIBLE ACROSS MUCH OF WEST CENTRAL TEXAS WITH THE ACTIVITY SHIFTING TO THE EAST AND SOUTHEAST BY MORNING. THE SEVERE THREAT WILL CONTINUE INTO THE MORNING HOURS. FOR MONDAY...THE UPPER LEVEL TROUGH SHIFT TO THE NORTHEAST AND A CLOSED LOW MOVES INTO THE NORTHERN PACIFIC COAST...WITH A SERIES OF UPPER LEVEL DISTURBANCES MOVING THROUGH THE UPPER LEVEL FLOW...THIS WILL KEEP THE MENTION OF PRECIPITATION IN THE FORECAST...WITH THE MAIN ACTIVITY SHIFTING TO THE EASTERN BIG COUNTRY AND THE HEARTLAND. 28 LONG TERM... WITH FOCUS ON SHORT TERM THREAT OF SEVERE WEATHER THIS AFTERNOON AND EVENING...WILL NOT SPEND AS MUCH TIME AS USUAL ON THE EXTENDED PERIOD TODAY. A GLANCE AT THE 12Z GFS DOES SHOW THAT THE FORECAST THROUGH MIDWEEK IS PRETTY MUCH ON TRACK. ACTIVITY THAT DEVELOPS OVER THE EASTERN COUNTIES ON MONDAY SHOULD BE EXITING THE AREA TO THE NORTHEAST BY MONDAY EVENING. A COLD FRONT IS THEN EXPECTED TO PUSH SOUTH INTO TX MONDAY NIGHT INTO TUESDAY AS A STRONG VORT MAX OVER THE INTER-MOUNTAIN WEST LIFTS NORTHEAST ACROSS THE CENTRAL PLAINS. THE 12Z NAM IS A BIT MORE AGGRESSIVE IN THE SOUTHWARD PROGRESS OF THE FRONT MONDAY NIGHT INTO TUESDAY...AND THIS WARRANTS KEEPING SOME POPS NEAR THE FRONT UP OVER THE BIG COUNTRY. THE FRONT THEN DROPS DOWN INTO THE AREA ON TUESDAY AND STALLS OUT. STORMS WILL PROBABLY DEVELOP DURING THE AFTERNOON OVER WEST TX IN THE UPSLOPE FLOW REGIME AND MOVE EAST ACROSS WEST CENTRAL TX LATE IN THE DAY AND INTO THE OVERNIGHT AS AN MCS ORGANIZES AND MOVES EAST ACROSS SOUTHERN OK/NORTH TX. THE MODELS BEGIN TO DIVERGE TOWARD THE END OF THE WEEK WITH THE DETAILS...ALTHOUGH THE GFS/ECMWF BRING A POLAR FRONT DOWN INTO TX AND EJECT A SOUTHERN STREAM DISTURBANCE INTO THE CENTRAL/SOUTHERN PLAINS NEXT WEEKEND. THE GFS IS COLDER THAN THE ECMWF...WHICH KEEPS THE BULK OF THE COOLER AIR TO OUR NORTHEAST. THE GFS IS ALSO FARTHER SOUTH WITH THE TRACK OF NEXT WEEKENDS SOUTHERN STREAM TROUGH WHICH WOULD BE MORE FAVORABLE FOR WIDESPREAD PRECIP THAN THE DRIER ECMWF. WITH ALL THESE UNCERTAINTIES TO DEAL WITH...WILL ONLY MAKE A FEW TWEAKS HERE AND THERE TO THE TEMPS AND POPS. I DID BRING TEMPS DOWN FOR THE LATTER PART OF THE WEEK AND INSERTED POPS FOR SAT/SAT NIGHT TIME FRAME. LACY FIRE WEATHER... SOUTHERLY LOW LEVEL FLOW WILL CONTINUE TO STREAM GULF MOISTURE IN ACROSS THE REGION AND THIS COMBINED WITH THE CONTINUING CHANCE FOR PRECIPITATION WILL KEEP THE FIRE DANGER LOW ACROSS WEST CENTRAL TEXAS THROUGH THE UPCOMING WEEK. 28 && .PRELIMINARY POINT TEMPS/POPS...
