Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
Scattered showers and thunderstorms developed along a surface trough draped across the southern Texas Panhandle during the afternoon hours of the 12th. The evening upper air sounding from Amarillo, Texas showed very little instability which kept most of these thunderstorms to remain below severe levels. One brief cell merger over Potter County provided enough additional vertical motion to allow one thunderstorm to produce a brief severe gust. No other severe gusts or hail were reported in association to these thunderstorms.

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE AMARILLO TX
1256 PM CDT MON AUG 12 2013
.AVIATION...
FOR THE 18Z TAFS, THIS IS A SOMEWHAT LOW CONFIDENCE FORECAST.
WHILE A SHRA/TSRA CAN'T BE RULED OUT VIRTUALLY ANY TIME AFTER 19Z,
HAVE THE HIGHEST CONFIDENCE OF VCTS AT KAMA 20Z-00Z. VCTS WILL ALSO
BE POSSIBLE AT KDHT AND KGUY 01Z-07Z, BUT CONFIDENCE IS ONLY
MODERATE AND TIMING IS LOW CONFIDENCE. BETTER CHANCES FOR STORMS AT
KDHT AND KGUY MAY BE AFTER 09Z, BUT CONFIDENCE OF OCCURRENCE TOO LOW
TO MENTION AT THIS TIME. IF THERE IS A DIRECT IMPACT TO A TERMINAL,
BRIEF LIFR CONDITIONS AND GUSTY WINDS UP TO 45 KT WILL BE POSSIBLE.
MVFR CONDITIONS WILL BE POSSIBLE 14Z-15Z AT KDHT AND KGUY, BUT
CONFIDENCE OF OCCURRENCE IS HIGHEST AT KGUY.

AVIATION...
12Z TAFS...ONGOING SHOWERS AND THUNDERSTORMS ACROSS EASTERN NM AND
THE SOUTHERN TX PANHANDLE MAY IMPACT KAMA THROUGH 15 OR 16Z...AND
HAVE INSERTED A TEMPO GROUP ACCORDINGLY. COULD SEE A SHOWER OR STORM
NEAR KDHT AS WELL THIS MORNING...ALTHOUGH CHANCES ARE LESS...AND THE
PRECIPITATION IS EXPECTED TO REMAIN SOUTH OF KGUY. ADDITIONAL SHOWERS
AND THUNDERSTORMS ARE EXPECTED TO DEVELOP LATER THIS AFTERNOON AND
TONIGHT. FOR NOW WILL CARRY A VCTS MENTION AT KDHT AND KGUY FROM
02-07Z AND 03-08Z RESPECTIVELY...MARKING THE LOCATIONS AND TIMES OF
HIGHEST CONFIDENCE OF THUNDERSTORM OCCURRENCE. HOWEVER...THUNDERSTORMS
CAN/T BE RULED OUT AT OTHER TIMES LATE THIS AFTERNOON AND TONIGHT...OR
AT THE KAMA TERMINAL.
OUTSIDE OF THE SHOWERS AND THUNDERSTORMS...VFR CONDITIONS ARE
ANTICIPATED. THERE IS A SMALL THREAT OF LOW CLOUDS AT KGUY LATE
TONIGHT BEHIND A WEAK FRONTAL BOUNDARY...BUT CONFIDENCE IN AN MVFR OR
LOWER CIG IS LOW AT THIS POINT. SOUTHWEST WINDS WILL GUST UP TO 20
KTS AT KAMA AND KDHT LATE THIS MORNING THROUGH THIS AFTERNOON.
KB
PREV DISCUSSION... /ISSUED 405 AM CDT MON AUG 12 2013/
DISCUSSION...
MOISTURE AXIS ACROSS THE PANHANDLES IS NOT GOING ANYWHERE ANY TIME
SOON. SHOWER AND THUNDERSTORM CHANCES WILL CONTINUE TODAY AS THE
MOISTURE COMBINES WITH WEAK SHORT WAVE TROUGHS MOVING ACROSS THE
REGION. A WEAK BOUNDARY COULD SETTLE INTO THE NORTHERN CWA TONIGHT
AND THIS MAY ENHANCE SHOWERS AND THUNDERSTORMS...SO HAVE GONE WITH
HIGHEST POPS THERE.
UPPER RIDGE OVER TEXAS WILL THEN MOVE BACK TO THE WEST WHERE IT WILL
TAKE UP RESIDENCE OVER THE SOUTHERN ROCKIES FOR THE REST OF THIS
FORECAST. WITH A RIDGE OVER THE WEST AND A TROUGH TO OUR EAST...
THIS WILL KEEP THE PANHANDLES IN A NORTHWEST FLOW ALOFT THROUGH THE
REST OF THIS WORK WEEK. A COLD FRONT WILL PUSH THROUGH THE
PANHANDLES TUESDAY NIGHT...SO THIS WILL AGAIN HELP TO ENHANCE THE
SHOWER AND THUNDERSTORM CHANCES. AM A LITTLE CONCERNED THAT WE MAY
HAVE A LULL IN THE RAIN CHANCES ON WEDNESDAY BEHIND THE FRONT. IT
MAY TAKE THE ATMOSPHERE SOME TIME TO RECOVER BEHIND THIS FRONT AND
WE MAY NOT SEE MOUNTAIN CONVECTION ROLL THIS WAY UNTIL WEDNESDAY
NIGHT AND THIS MAY BE CONDITIONAL BASED ON HOW MUCH INSTABILITY IS
FOUND ACROSS THE PANHANDLES. AT ANY RATE...DO NOT HAVE THE
CONFIDENCE TO LOWER POPS ON WEDNESDAY NOW AS THERE WILL BE A LOT OF
MESOSCALE FACTORS PLAYING IN THIS SCENARIO AS WELL.
NORTHWEST FLOW ALONG WITH UPPER LEVEL SHORT WAVE TROUGHS WILL KEEP
RAIN CHANCES IN THE FORECAST THROUGH SATURDAY. THE FLOW ALOFT
BECOMES MORE NORTHERLY BY SUNDAY...SO IT MAY BE TOUGHER TO BRING
MOUNTAIN CONVECTION INTO THE PANHANDLES. WE WILL HAVE TO RELY ON A
SHORT WAVE TROUGH MOVING THROUGH THE FLOW TO BRING US A CHANCE OF
RAIN. AT THIS POINT...AM NOT WILLING TO ADD POPS BASED ON THE
POSSIBILITY THAT A SHORT WAVE TROUGH MAY BE MOVING BY AT THIS TIME.
TEMPERATURES WILL BE TRICKY BEHIND THE FRONT ON WEDNESDAY. IF
CLOUDS STAY IN ALL DAY...THEN OUR HIGH TEMPERATURE FORECAST WILL BE
WAY TOO WARM.
FIRE WEATHER...
NO ELEVATED OR CRITICAL FIRE WEATHER CONDITIONS ARE EXPECTED THROUGH
SUNDAY DUE TO THE EXPECTED RAINFALL. RELATIVE HUMIDITY VALUES WILL
ALSO STAY ABOVE 20 PERCENT AND WINDS ARE EXPECTED TO REMAIN BELOW 20
MILES AN HOUR.
