NWS San Angelo, TX wrote its last area forecast discussion before the first event at Apr 23, 10:19 PM CST, 5 hours 2 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN ANGELO TX 1119 PM CDT THU APR 23 2009 .AVIATION... /06Z UPDATE/ EVENING THUNDERSTORM ACTIVITY HAS DECREASED WITH THE LOSS OF DAYTIME HEATING. RESIDUAL SHOWERS WILL BE POSSIBLE OVER KSJT AND KSOA TROUGH 10Z. A LLJ WILL CAUSE LLWS FOR THE NEXT SEVERAL HOURS OVER THE WESTERN TERMINALS. MVFR CEILINGS ARE EXPECTED TO SPREAD OVER THE SOUTHEAST TERMINALS BY DAYBREAK AND LIFT BY EARLY AFTERNOON. SOUTHERLY WINDS GUSTING TO OVER 20KT WILL DEVELOP OVER ALL TAF SITES BY MIDMORNING...DECREASING BY EVENING. && .PREV DISCUSSION... /ISSUED 752 PM CDT THU APR 23 2009/ UPDATE... INCREASED POPS ACROSS WESTERN CONCHO VALLEY TO REFLECT CURRENT COVERAGE...BUT EXPECT STORMS TO WEAKEN AFTER SUNSET. MAY STILL SEE WIDELY SCATTERED STORMS DEVELOP EASTWARD AS WEAK SHORTWAVE MOVES ACROSS THE AREA, BUT DONT EXPECT WIDESPREAD COVERAGE. PREV DISCUSSION... /ISSUED 552 PM CDT THU APR 23 2009/ AVIATION... /00Z UPDATE/ VFR CONDITIONS WILL CONTINUE OVER WEST CENTRAL TEXAS THROUGH THE NIGHT. MVFR CEILINGS MAY MOVE OVER THE SOUTHEASTERN TAFS BY DAYBREAK BUT SHOULD LIFT BY LATE MORNING. A DEVELOPING LLJ OVER THE AREA WILL RESULT IN A 45-50KT LLWS OVER ALL TAFS BY 06Z. THERE WILL BE ISOLATED THUNDERSTORMS ASSOCIATED WITH AN UPPER LEVEL DISTURBANCE MOVING WEST TO EAST OVER THE AREA THROUGH THE TAF PERIOD...BUT WILL ONLY INCLUDE VCTS OVER THE SOUTHEASTERN TAF SITES AT THIS TIME. PREV DISCUSSION... /ISSUED 301 PM CDT THU APR 23 2009/ SHORT TERM... HIGH BASED SHOWERS AND ISOLATED STORMS ARE DEVELOPING ON THE HIGHER TERRAIN OF SOUTHWEST TX AHEAD OF AN UPPER LEVEL WAVE. THIS ACTIVITY IS EXPECTED TO MOVE NORTHEAST INTO WEST CENTRAL TX LATE THIS AFTERNOON AND EARLY THIS EVENING. AS THIS WAVE AND THE ASSOCIATED QG FORCING FOR ASCENT MOVES EAST ACROSS TX TONIGHT...MORE WIDELY SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED TO DEVELOP ACROSS THE REGION. FOR THIS REASON...WILL INSERT SLGT CHC POPS OVER A LARGER PORTION OF W CNTRL TX TONIGHT. WILL INSERT SLGT CHC POPS IN THE EAST FRIDAY...MAINLY FOR THE MORNING HOURS...AS THE LIFT FROM THE UPPER WAVE IS EXPECTED TO EXIT THE REGION BY 18Z. THE NAM/GFS DO SHOW SOME DEVELOPMENT OVER THE HILL COUNTRY FRIDAY AFTERNOON WHICH IS EXPECTED TO LIFT NORTHEAST INTO CENTRAL TX. SOME OF THIS ACTIVITY MAY CLIP OUR EASTERN COUNTIES...IF IT DEVELOPS AT ALL DUE TO UNFAVORABLE SYNOPTIC SCALE DESCENT BEHIND UPPER WAVE. LACY LONG TERM... LOOKS LIKE AN ACTIVE PATTERN SETTING UP FOR THIS WEEKEND INTO NEXT WEEK WITH AN UPPER LEVEL TROUGH ACROSS THE WESTERN CONUS AND EMBEDDED SHORTWAVES MOVING THROUGH THE UPPER LEVEL FLOW. THIS COMBINED WITH A DRYLINE THAT BEGINS TO SHARPENS UP ON SATURDAY AFTERNOON AND MEANDERS BACK AND FORTH INTO WESTERN PORTIONS OF WEST CENTRAL TEXAS...BRINGING A CHANCE FOR THUNDERSTORMS SATURDAY NIGHT INTO MOST OF NEXT WEEK. THE BEST CHANCE FOR THUNDERSTORMS APPEARS TO BE SUNDAY AND MONDAY EVENINGS AS SHORTWAVES MOVE ACROSS THE AREA AND A LLJ DEVELOPS. THERE IS STILL SOME UNCERTAINTY ON THE TIMING OF THE SHORTWAVES THIS FAR OUT...SO WILL HAVE TO WAIT UNTIL EVENT GETS CLOSER TO FINE TUNE THE POPS BUT FOR NOW HAVE 30S AND LOW 40S ACROSS MUCH OF THE AREA FOR SUNDAY NIGHT INTO TUESDAY MORNING. ALSO ON MONDAY EVENING INTO TUESDAY THE MODELS HAVE A COLD FRONT PUSHING SOUTH INTO WEST CENTRAL TEXAS. HOWEVER...THE MODELS HAVE NOT BEEN CONSISTENT WITH HOW FAR SOUTH THE FRONT MOVES BUT THINK CONVECTION WILL PUSH THE FRONT FARTHER SOUTH INTO THE BIG COUNTRY AND INTO THE NORTHERN PORTIONS OF THE CONCHO VALLEY AND HEARTLAND WHICH IS FARTHER SOUTH THAN THE MODELS ARE CURRENTLY SHOWING. GIVEN THE EXTENSIVE CLOUD COVERAGE HAVE KEPT TEMPERATURES IN THE UPPER 70S TO MID 80S FOR THIS WEEKEND INTO NEXT WEEK. LOW LEVEL SOUTHERLY FLOW WILL KEEP MOISTURE ACROSS THE REGION...KEEPING OVERNIGHT LOWS IN THE 60S. FIRE WEATHER... DUE TO INCREASING LOW LEVEL MOISTURE AND CALMER THAN EXPECTED WINDS...CONDITIONS ARE STRUGGLING TO REACH CRITICAL LEVELS THIS AFTERNOON. AS A RESULT...I WILL LIKELY CANCEL THE RED FLAG WARNING AND MENTION ELEVATED FIRE WEATHER CONDITIONS. FOR THE NEXT FEW DAYS THE DRYLINE IS EXPECTED TO STAY TO THE WEST OF W CNTRL TX...AND GULF MOISTURE WILL CONTINUE TO STREAM NORTH INTO THE AREA WITH FORECASTED AFTERNOON RH VALUES IN THE 30S AND 40S. THUS...THE FIRE DANGER THREAT WILL BE REDUCED THRU THE END OF THE WEEK. INCREASING CHANCES OF RAIN AND THUNDERSTORMS...ALONG WITH MORE CLOUD COVER AND LOW LEVEL MOISTURE...SHOULD KEEP THE FIRE DANGER BELOW ELEVATED LEVELS NEXT WEEK.
