AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE AMARILLO TX 1239 PM CDT SUN AUG 7 2011 .AVIATION... FOR THE 18Z TAFS...VFR CONDITIONS ARE EXPECTED. THE MAIN CHALLENGE IS DEALING WITH POSSIBLE TSRA THROUGH 03Z. MENTIONED CB AT ALL SITES BEGINNING AT 20Z AT KAMA AND 22Z AT KDHT AND KGUY AS COVERAGE IS EXPECTED TO BE ISO TO SCT AT BEST. CONFIDENCE OF TSRA REMAINS RATHER LOW. IF TSRA DIRECTLY AFFECTS ANY SITE...BRIEF MVFR/IFR CONDITIONS AND GUSTY WINDS WOULD BE POSSIBLE. ANY TSRA SHOULD DISSIPATE BY 03Z. A FRONT WILL SWITCH WINDS TO THE NORTH AT ALL SITES 06-15Z. MBS && .PREV DISCUSSION... /ISSUED 1205 PM CDT SUN AUG 7 2011/ UPDATE... FORECAST FOR THE REST OF TODAY LOOKS TO BE ON TRACK...AND HAVE ONLY MADE SOME MINOR ADJUSTMENTS WITH THE UPDATE. MAIN CHANGE WAS TO SLIGHTLY INCREASE POPS INTO THE 30 PERCENT RANGE ACROSS THE SOUTHEAST AND NORTHWEST CWA. MIDLEVEL MOISTURE PLUME CONTINUES TO SHIFT SOUTHEAST...BUT REMAINS DRAPED ACROSS THE FAR SOUTHEAST CWA PER LATEST WATER VAPOR IMAGERY. MIDLEVEL CLOUD DECK REMAINS ACROSS THIS AREA...AND A FEW SHOWERS HAVE RECENTLY DEVELOPED IN THIS AREA. WITH CONTINUED HEATING THIS AFTERNOON AND AVAILABLE MOISTURE...BELIEVE SHOWERS AND STORMS WILL CONTINUE TO DEVELOP IN THIS AREA. DIFFERENTIAL HEATING ON THE EDGES OF THIS CLOUD DECK MAY AID DEVELOPMENT. THE OTHER PREFERRED AREA FOR THUNDERSTORM DEVELOPMENT THIS AFTERNOON AND EVENING WILL BE ACROSS THE OK PANHANDLE AND NORTHWEST TX PANHANDLE. WHILE MIDLEVELS ARE DRIER IN THIS AREA...SURFACE DEWPOINTS REMAIN IN THE UPPER 50S TO NEAR 60...WHICH COMBINED WITH STRONG DIURNAL HEATING WILL GENERATE SUFFICIENT INSTABILITY TO GENERATE CONVECTION. A SURFACE TROUGH WILL SHARPEN IN THIS AREA THIS AFTERNOON...AND AN OUTFLOW BOUNDARY FROM CONVECTION OVER NORTHERN KS HAS SLIPPED INTO THE OK PANHANDLE. BOTH OF THESE FEATURES WILL PROVIDE AN ADDED FOCUS FOR THUNDERSTORM DEVELOPMENT. SIMILAR TO THE LAST SEVERAL DAYS...STRONG WIND GUSTS WILL BE THE MAIN HAZARD WITH ANY STORMS GIVEN HIGH-BASED NATURE/INVERTED-V SOUNDINGS. COULD ALSO SEE SOME LOCALLY HEAVY RAIN...ALTHOUGH THE AIRMASS HAS DRIED SOMEWHAT OVER MOST OF THE PANHANDLES /EXCEPT FAR SOUTHEAST/ DUE TO THE SOUTHWARD SHIFT OF THE MIDLEVEL MOIST PLUME. ALSO TWEAKED HIGH TEMPERATURES TODAY...INCREASING A TAD IN CLOUD FREE AREAS WHICH HAVE BEEN QUICK TO WARM TODAY...AIDED IN PART BY A MILD START TO THE DAY. KB PREV DISCUSSION... /ISSUED 350 AM CDT SUN AUG 7 2011/ DISCUSSION... A FRONTAL BOUNDARY ACROSS SOUTHEASTERN COLORADO AND SOUTHERN KANSAS WILL EVENTUALLY PUSH SOUTH INTO THE FORECAST AREA MONDAY. THE MONSOONAL MOISTURE PLUME HAS SHIFTED FURTHER EAST AND SOUTH EXTENDING FROM NORTHWEST MEXICO ACROSS SOUTHERN NEW MEXICO AND INTO OKLAHOMA. CONVECTION THIS AFTERNOON THROUGH EARLY TONIGHT WILL BE CONFINED MAINLY TO THE EASTERN AND SOUTHERN SECTIONS OF THE TEXAS PANHANDLE...ALTHOUGH CANNOT COMPLETELY RULE OUT PRECIP ACROSS ALL OF THE PANHANDLES. A SHORTWAVE TROUGH WILL TRACK EAST FROM THE TEXAS PANHANDLE TODAY INTO OKLAHOMA BY MONDAY. COLD FRONT SHOULD PUSH ACROSS MOST OF THE FORECAST AREA EXCEPT THE SOUTHEASTERN TEXAS PANHANDLE MONDAY EVENING. FRONT THEN EXPECTED TO PUSH SOUTH AND EAST ACROSS THE REMAINDER OF THE FORECAST AREA MONDAY NIGHT AND ACROSS SOUTHERN OKLAHOMA AND THE TEXAS SOUTH PLAINS BY TUESDAY. FRONT SHOULD LIFT BACK NORTH AND EAST ACROSS THE SOUTHERN AND WESTERN TEXAS PANHANDLE TUESDAY NIGHT AND EARLY WEDNESDAY. DRIER AND SLIGHTLY COOLER EARLY THIS WEEK WITH CONVECTION EXPECTED TO RETURN BY TUESDAY NIGHT AS THE FRONTAL BOUNDARY LIFTS NORTH AS A WARM FRONT AND SHORTWAVE ENERGY TRACKS ACROSS THE FORECAST AREA. ZONAL UPPER FLOW AROUND MID TO LATE WEEK WITH A FRONTAL BOUNDARY ACROSS THE PANHANDLES WILL MAINTAIN CONTINUED CHANCES FOR CONVECTION WEDNESDAY THROUGH SATURDAY NIGHT. INCREASED CLOUD COVER...CHANCES FOR CONVECTION...AND FRONTAL BOUNDARY IN THE FORECAST AREA SHOULD KEEP MAX TEMPERATURES BELOW THE CENTURY MARK FOR THE LATTER HALF OF THE WEEK. SCHNEIDER FIRE WEATHER... ELEVATED TO CRITICAL FIRE WEATHER CONDITIONS ARE NOT EXPECTED OVER THE PANHANDLES THROUGH LATE THIS WEEK AND EARLY NEXT WEEKEND.
