An upper high was located near the New Mexico-Mexico border region with weak flow aloft. A moist southeast surface flow beneath this high allowed dew points to remain in the mid to upper 50s across the region.

The episode as NWS EPZ wrote it up.
An upper high was located near the New Mexico-Mexico border region with weak flow aloft. A moist southeast surface flow beneath this high allowed dew points to remain in the mid to upper 50s across the region. This combination led to ample instability with slow moving storms to produce localized flash flooding in Grant County.

NWS El Paso, TX wrote its last area forecast discussion before the first event at Aug 13, 1:28 PM MST, 3 hours 16 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE EL PASO TX/SANTA TERESA NM 228 PM MDT TUE AUG 13 2013 .SYNOPSIS... HIGH PRESSURE ALOFT ANCHORED OVER THE SOUTHWESTERN U.S. WILL KEEP TEMPERATURES WARM ACROSS THE BORDERLAND THROUGH THE REST OF THE WEEK. AFTERNOON HIGHS WILL AVERAGE 4 TO 7 DEGREES ABOVE NORMAL. MODERATE MONSOON MOISTURE REMAINS TRAPPED IN THE AIRMASS OVER THE REGION. WARM DAYTIME TEMPERATURES WILL WORK IN CONCERT WITH THE MOISTURE TO PRODUCE UNSTABLE AFTERNOON CONDITIONS. THE RESULT WILL BE MORE ISOLATED TO SCATTERED STORMS EACH AFTERNOON ACROSS THE REGION. BETTER STORM CHANCES FOR EAST AREAS WEDNESDAY AND THURSDAY...AND WESTERN AREAS FRIDAY AND SATURDAY. && .DISCUSSION... HIGH PRESSURE ALOFT AND TRAPPED MONSOON MOISTURE BELOW PRETTY MUCH DESCRIBE THE PATTERN FOR MUCH OF THE FORECAST PERIOD. MODELS SHOW A BROAD AND FAIRLY WEAK UPPER TROUGH WILL SWEEP SE ACROSS THE N U.S. PLAINS TONIGHT. THIS ALLOWS SURFACE HIGH PRESSURE OVER THE MID-WEST TO PUSH A SURFACE FRONTAL BOUNDARY SOUTH AND WEST UP AGAINST THE ROCKIES AND INTO N TEXAS TONIGHT AND TOMORROW. MODELS USE THIS FRONT AS A FOCUS FOR CONVECTIVE ACTIVITY TONIGHT AND WEDNESDAY. THE QUESTION IS: DOES THIS FEATURE GET INTO AND IMPACT OUR FORECAST AREA. MODELS SUGGEST THE ANSWER IS NO. BUT IT DOES COME CLOSE WITH A SLOSH UP AGAINST THE CENTRAL NM MOUNTAIN CHAIN TONIGHT. THE LAST FRONT PUSHED FARTHER WEST THAN THE MODELS INDICATED IT WOULD. DESPITE THIS...THE GFS...NAM...ECMWF ALL SUGGEST IT WILL FALL SHORT OF PUSHING INTO THE AREA. WE'VE HEDGE OUR BETS JUST A BIT...AND HAVE SLIGHTLY ELEVATED E ZONE POPS OVER W ZONE POPS FOR WED/THU. DEWPOINTS MAY CREEP UP AND THERE COULD BE A WEAK UPPER IMPULSE DROPPING IN OVER THE FRONT FROM THE NW. THE FRONT QUICKLY WASHES OUT AND RETREATS EAST THU AS THE UPPER HIGH BEGINS TO DRIFT WEST OF THE CWFA. PCPN FOCUS FEATURES LOOK ABSENT...BUT MOISTURE REMAINS NEAR 1" PW. TEMPS WILL BE QUITE WARM WITH AFTERNOON TEMPS STILL 4-8 DEGREES ABOVE NORMALS. THUS DAILY DESTABILIZATION LOOKS PROBABLE. FOR FRI...SLIGHTLY DRIER AIR MOVES IN ALOFT ON THE NORTHERLY FLOW ON THE E SIDE OF THE UPPER HIGH. EXPECT FEWER STORMS E AND MORE STORMS WEST FOR FRI. SATURDAY ONWARD...THE RIDGE SMEARS BACK EAST A BIT AS A WEST COAST TROUGH PUSHES TOWARD THE GREAT BASIN. THIS ALLOWS THE RELATIVELY DIFFUSE MONSOON MOISTURE PLUME TO MOVE OVER ALL ZONES. WE SHOULD GO TO A DIURNAL CONVECTIVE PATTERN WILL ALL LOWLAND ZONES NEARLY EQUAL ON PCPN CHANCES...WITH THE MTN ZONES FAVORED FOR SCATTERED COVERAGE. && .AVIATION...VALID 14/00Z-15/00Z. -SHRA/TSRA THRU 06Z ACROSS MAINLY HIGHER TERRAIN WITH A FEW SHOWERS DRIFTING EAST OVER THE LOWLANDS. OTHERWISE VFR CONDITIONS WILL REMAIN THE GENERAL RULE ACROSS THE REGION WITH SCT060-080 SCT-BKN150-200 AND SFC WINDS GENERALLY REMAINING BELOW 12 KNOTS. 26-GRZYWACZ && .FIRE WEATHER... UPPER HIGH OVER REGION WILL SHIFT INTO THE FAR SW NM/SE AZ REGION AND REMAIN NEARLY STATIONARY THROUGH THE WEEKEND. THIS WILL KEEP UPPER LEVEL WINDS LIGHT WHICH IN TURN WILL KEEP SMOKE DISPERSION POOR TO FAIR. AS A MORE NORTHERLY FLOW ALOFT STRENGTHENS THERE WILL BE A LITTLE DRIER AIR MOVING IN ALOFT...BUT THERE WILL BE A WEAK BACK DOOR COLD FRONT MOVING IN THURSDAY WHICH WILL BRING BACK A QUICK SURGE OF MOISTURE. IN GENERAL THOUGH...ISOLATED DAILY THUNDERSTORM COVERAGE WILL CONTINUE FOR THE LOWLANDS WITH SCATTERED COVERAGE FOR AREA MOUNTAINS. TEMPERATURES WILL REMAIN NEAR TO ABOUT 5 DEGREES ABOVE NORMAL THROUGH THE WEEKEND WITH SOME LOWLAND LOCATIONS POSSIBLY APPROACHING THE CENTURY MARK AGAIN STARTING FRIDAY WITH MINIMUM RELATIVE HUMIDITIES BACK INTO THE TEENS. 26-GRZYWACZ && .PRELIMINARY POINT TEMPS/POPS...
