The local office's own words before this special weather statement went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Amarillo, TX wrote its last area forecast discussion before this special weather statement went out at Aug 6, 3:27 PM CDT, 10 minutes earlier.
Area forecast discussion, Aug 6, 3:27 PM CDT, 10 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE AMARILLO TX 327 PM CDT TUE AUG 6 2013 .DISCUSSION... SHOWERS AND THUNDERSTORMS WERE DEVELOPING ALONG A BOUNDARY THAT STRETCHED SOUTHWEST TO NORTHEAST FROM NORTHERN DEAF SMITH COUNTY TO NEAR CANADIAN. THESE SHOWERS AND THUNDERSTORMS ARE LIKELY DIURNALLY DRIVEN AND WILL MOST LIKELY WANE AFTER SUNSET. A MORE ORGANIZED AREA OF SHOWERS AND THUNDERSTORMS IS EXPECTED TO MOVE EAST ACROSS THE NORTHERN CWA FROM NORTHEAST NEW MEXICO TONIGHT. A COLD FRONT WILL PUSH INTO THE PANHANDLES FROM THE NORTH ON WEDNESDAY. RIGHT NOW IT APPEARS THAT IT WILL PULL UP STATIONARY ACROSS THE NORTHERN TEXAS PANHANDLE BY PEAK HEATING...SO WILL KEEP THE BEST CHANCE OF SHOWERS AND THUNDERSTORMS THERE. BUT...IF THIS FRONT MOVES FURTHER SOUTH...THEN WE MAY NEED TO CONSIDER BUMPING POPS UP ACROSS THE SOUTH. SOME OF THE STORMS MAY BECOME SEVERE WEDNESDAY AFTERNOON AND WEDNESDAY EVENING. SEE THE LATEST SWODY2 FOR MORE DETAILS. FLOODING MAY ALSO BE AN ISSUE...ESPECIALLY IN THE NORTHWEST WHERE IT HAS BEEN WET LATELY. NEXT COLD FRONT MOVES THROUGH THE AREA THURSDAY AFTERNOON AND THURSDAY NIGHT...SO POPS FOR THIS TIMEFRAME LOOK GOOD FROM THE PREVIOUS FORECAST. THERE COULD BE A LULL IN THE SHOWER AND THUNDERSTORM ACTIVITY FRIDAY AND FRIDAY NIGHT...BUT CONFIDENCE IS NOT HIGH ENOUGH TO REMOVE POPS FROM ANY GIVEN AREA. THE FRONT MAY TAKE SOME MOISTURE AND INSTABILITY WITH IT TO OUR SOUTH...SO THIS COULD BE A DRIER DAY. THE INSTABILITY SHOULD RECOVER SOME ON SATURDAY AND SHOWERS AND THUNDERSTORMS MOVING EAST FROM THE MOUNTAINS SHOULD MAKE IT INTO THE PANHANDLES. WILL CONTINUE WITH A DRY FORECAST AFTER SATURDAY NIGHT FOR NOW. SHOWERS AND THUNDERSTORMS WILL STILL BE A POSSIBILITY SUNDAY THROUGH EARLY NEXT WEEK...BUT THE MODELS DO NOT AGREE ON HOW THE UPPER AIR PATTERN WILL EVOLVE...SO WILL KEEP POPS OUT. && .FIRE WEATHER... NO ELEVATED OR CRITICAL FIRE WEATHER CONDITIONS ARE EXPECTED THROUGH THIS WEEK GIVEN THE RAIN CHANCES AND THE FACT THAT LOWEST RELATIVE HUMIDITY VALUES SHOULD REMAIN ABOVE 20 PERCENT. && .PRELIMINARY POINT TEMPS/POPS...
