The episode as NWS AMA wrote it up.
Several widespread precipitation events during the month of August provided continued relief in drought conditions across the Oklahoma Panhandle. Guymon recorded near average precipitation for the month of August with 2.77 inches of precipitation (0.98 inch above normal). This August ranked as the 48th coolest and the 8th wettest August for the Oklahoma Panhandle on record. The U.S. Drought Monitor showed slight improvements but the vast majority of the Panhandle remains in Extreme (D3) Drought rating. With that being said, there are small portions of the far western and far eastern Panhandle that have improved to the Severe Drought (D2) rating.
The widespread precipitation during the month has provided significant short-term improvement in upper zone soils, and has helped in deeper soil moisture. Many farmers were able to take advantage of the increased moisture by cutting back on the amount of supplemental watering during a period of higher water demand by crops. The Palmer Drought Severity Index showed improvement during the month of August with the Oklahoma Panhandle now rated as Moderate Drought. For the second month in a row dryland crops showed signs of improvement. However, water watches remain in effect for several public water systems through August while voluntary to mandatory water restrictions have been enacted.
Economic losses due to the drought during August were estimated near $10 million (D3)/$5 million (D2) a county, and were predominately the result for poor growth of summer crops, marginal supplemental watering, reduction of cattle herd sizes, and supplemental feed for cattle in pastures and rangeland.

NWS Amarillo, TX wrote its last area forecast discussion before the first event at Jul 31, 10:49 PM CST, 1 hour 11 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE AMARILLO TX 1149 PM CDT WED JUL 31 2013 .AVIATION... ISOLATED TO SCATTERED THUNDERSTORMS WILL BE IN THE VICINITY OF OUR TERMINALS FOR THE NEXT 2 OR 3 HOURS...BUT IT APPEARS UNLIKELY THAT ANY OF THESE WILL HAVE A DIRECT IMPACT TO THE TERMINALS. LIGHT SURFACE WINDS AND MOIST LOWER LEVELS SHOULD PROMOTE DEVELOPMENT OF MVFR BR BEGINNING AROUND 08Z OR 09Z THURSDAY...WHICH SHOULD DISSIPATE AROUND 14Z THURSDAY. SOUTHERLY SURFACE WINDS PREVAIL DURING THE DAY ON THURSDAY...WITH SPEEDS BELOW 20 KT. BY 21Z THURSDAY...ISOLATED TO SCATTERED THUNDERSTORMS EXPECTED TO DEVELOP AGAIN ACROSS THE FORECAST AREA...WITH ACTIVITY LINGERING WELL INTO THE EVENING. COCKRELL && .PREV DISCUSSION... /ISSUED 1117 PM CDT WED JUL 31 2013/ UPDATE... ALLOWED THE SEVERE THUNDERSTORM WATCH TO EXPIRE AT 11 PM. WILL SEE SOME LINGERING SHOWERS AND THUNDERSTORMS OVERNIGHT...BUT THE SEVERE THREAT HAS WANED. LOCALLY HEAVY RAIN...WIND GUSTS OF 40 TO 50 MPH...AND SMALL HAIL WILL REMAIN POSSIBLE WITH A FEW STRONGER STORMS. COULD ALSO SEE SOME FOG DEVELOP OVERNIGHT GIVEN THE MOIST LOW-LEVEL AIRMASS IN PLACE...LIGHT WINDS...AND RAINFALL IN SPOTS. KB PREV DISCUSSION... /ISSUED 758 PM CDT WED JUL 31 2013/ UPDATE... EXPANDED SEVERE THUNDERSTORM WATCH SLIGHTLY SOUTHEAST ACROSS THE NORTHEAST TX PANHANDLE TO COVER STRONG TO SEVERE CONVECTION CURRENTLY PROPAGATING SOUTH/SOUTHEAST OUT OF SOUTHWEST KS AND THE EASTERN OK PANHANDLE. INSTABILITY STARTS TO DROP OFF PRETTY SIGNIFICANTLY SOUTH OF ROBERTS AND HEMPHILL COUNTIES...WHICH SHOULD LIMIT THE SOUTHWARD EXTENT OF THE SEVERE THREAT. KB PREV DISCUSSION... /ISSUED 703 PM CDT WED JUL 31 2013/ UPDATE... QUICK UPDATE TO INCREASE EVENING PRECIP CHANCES ACROSS THE EASTERN OK PANHANDLE AND PORTIONS OF THE SOUTHWEST TX PANHANDLE BASED ON RADAR TRENDS. KB PREV DISCUSSION... /ISSUED 622 PM CDT WED JUL 31 2013/ AVIATION... SCATTERED THUNDERSTORMS ALONG NORTHERN AND WESTERN PERIPHERIES OF FORECAST AREA WILL MOVE SOUTH AND SOUTHEAST...POTENTIALLY IMPACTING ALL TERMINALS THIS EVENING. WILL CONTINUE TO MONITOR RADAR TRENDS BEFORE ADDING THUNDER AS PREVAILING WEATHER. THUNDERSTORMS WILL HAVE POTENTIAL TO BECOME SEVERE...WITH GUSTS ABOVE 50 KT...HAIL...AND BRIEF IFR VISIBILITIES IN VERY HEAVY RAIN. AMENDMENTS MAY BE FORTHCOMING. SOME EARLY MORNING BR WILL LIKELY DEVELOP IN AREAS THAT RECEIVE RAIN. ISOLATED TO SCATTERED THUNDERSTORMS EXPECTED THURSDAY AFTERNOON. COCKRELL PREV DISCUSSION... /ISSUED 406 PM CDT WED JUL 31 2013/ DISCUSSION... SHORT TERM...THIS AFTERNOON THROUGH THURSDAY AFTERNOON CURRENTLY UNDER A SEVERE THUNDERSTORM WATCH THROUGH THIS AFTERNOON/EVENING. CURRENTLY KEEPING AN EYE ON THE STORMS IN COLORADO AND KANSAS AS STORMS HAVE BEEN MOVING SOUTH/SOUTHWEST SO THOSE STORMS HAVE THE BEST CHANCE AT MAKING IT TO THE PANHANDLES....BUT NEW STORMS COULD ALSO FORM OVER ANY REMNANT BOUNDARIES IN THE AREA. VERY SLOW STORM MOTIONS WILL LEAD TO POTENTIAL FLOODING ISSUES WHEREVER STORMS DECIDE TO PARK AND TAP INTO PWATS OVER 1 INCH. VERY UNSTABLE AIR MASS ABOVE US MEANS THAT ANY STORMS THAT DO DECIDE TO BREAK THROUGH AND TAP INTO INSTABILITY WILL HAVE A GOOD CHANCE OF GOING SEVER QUICKLY. THIS COMBINED WITH RELATIVELY LOW CLOUD BASES MEANS WE CANT COMPLETELY RULE OUT AN ISOLATED TORNADO...EVEN THOUGH THE THREAT IS VERY LOW. ANY STORMS THAT ARE IN THE AREA SHOULD EITHER DISSIPATE OR MOVE ON OUT OVERNIGHT...BRINGING A BRIEF LULL IN POPS TOMORROW MORNING. THEN NORTHWEST FLOW BRINGS YET ANOTHER CHANCE FOR ISOLATED STORMS TOMORROW AFTERNOON AND EVENING MOSTLY TO THE WESTERN OKLAHOMA PANHANDLE AND THE NORTHWESTERN TEXAS PANHANDLE. ABM LONG TERM...THURSDAY NIGHT THROUGH TUESDAY NIGHT AS FOR THE OVERALL PATTERN THROUGH MID NEXT WEEK...UPPER LEVEL RIDGE OVER NEW MEXICO STILL EXPECTED TO MOVE EASTWARD AND BUILD OVER THE TEXAS PANHANDLE BY THIS WEEKEND. IT SHOULD THEN BUILD FURTHER EAST OVER NORTH TEXAS BY THE MIDDLE OF NEXT WEEK. SHORTWAVE TROUGHS RIDING AROUND THE RIDGE WILL PROVIDE THE TRIGGER FOR THUNDERSTORMS MOST AFTERNOONS. A SURFACE TROUGH WILL BE STRETCHED FROM NORTHEAST NEW MEXICO INTO SOUTHEASTERN KANSAS THROUGH THE WEEKEND...SERVING AS A FOCUS FOR THESE THUNDERSTORMS. FAVORED THE GFS/NAM SCENARIO OF A FURTHER SOUTH PUSH OF THIS TROUGH AND ITS POPS. A SURFACE LOW THEN FORMS AND EDGES INTO THE NORTHERN PANHANDLES...EARLY NEXT WEEK. THIS WILL KEEP PRECIP CHANCES MAINLY CONFINED TO THE OKLAHOMA PANHANDLE AND NORTHERN TEXAS PANHANDLE FOR THE SECOND HALF OF THE FORECAST PACKAGE. TEMPERATURES SHOULD BE ABOVE NORMAL...WITH TEMPERATURES RISING INTO THE UPPER 90S TO LOW 100S POSSIBLE BEFORE THE WEEKEND. SEVERE CHANCES WILL BE LOW AFTER TONIGHT...WITH CAPE VALUES ONLY EXPECTED TO TOP OUT AROUND 700 TO 800 J/KG DURING THE AFTERNOONS. FORECAST SOUNDINGS ARE MORE INDICATIVE OF EFFECTIVE RAIN PRODUCING THUNDERSTORMS NEAR THE SURFACE TROUGH...WHERE PWATS NEAR 1.5 INCHES MOST OF THE PERIOD. NF FIRE WEATHER... 20 FOOT WIND SPEEDS SHOULD REMAIN BELOW 20 MPH AND RELATIVE HUMIDITY VALUES ABOVE 20 PERCENT THROUGH THE MIDDLE OF NEXT WEEK. NO ELEVATED OR CRITICAL FIRE WEATHER CONDITIONS ARE EXPECTED THROUGH THIS PERIOD. NF HYDROLOGY... WITH SLOW AND ALMOST STATIONARY STORM MOTIONS THIS AFTERNOON AND TONIGHT...COUPLED WITH A RELATIVELY MOIST ATMOSPHERE...THE POTENTIAL FOR HEAVY RAIN WILL BE A CONCERN. AFTER RECENT RAINFALL...FLASH FLOODING AND RIVER FLOODING MAY BE ISSUES TONIGHT AND THROUGH THE NEXT WEEK. THE GREATEST THREAT WILL BE ACROSS THE OKLAHOMA AND NORTHERN TEXAS PANHANDLES.
