What happened

The episode as NWS EPZ wrote it up.

A large cluster of thunderstorms dropped 3 to 5 inches of rain on much of the triangle between Las Cruces, Hatch and Deming, which is an unusually large area for such rainfall amounts in the desert southwest. The Placitas Arroyo near Hatch breached for the third time in 3 weeks, flooding mainly farm land. A flood wave resulted in minor flooding of the Rio Grande River downstream into the El Paso area, the third time this month. Before August 1st, the previous time was August 1999. On the north side of the Sierra De La Uvas Mountains, a huge amount of runoff flooded the desert and led to the closure of Interstate 10 between Deming and Las Cruces for several hours. Closing the interstate along this stretch is not uncommon during dust storms, but extremely rare for flooding. The flooding also did damage to structures in this sparsely populated area.

.SYNOPSIS...
AN APPROACHING COLD FRONT WILL HELP INCREASE OUR RAIN CHANCES AND
DECEASE OUR AFTERNOON HIGH TEMPERATURES FOR THE NEXT COUPLE OF
DAYS. WE WILL CONTINUE TO SEE A SLIGHT CHANCE FOR THUNDERSTORMS
FOR THE REST OF THE WEEK...WITH TEMPERATURES RUNNING NEAR NORMAL.
BY THE END OF THE WEEKEND ANOTHER COLD FRONT WILL MOVE ACROSS THE
AREA...AGAIN COOLING OUR TEMPERATURES AND INCREASING OUR CHANCES
FOR RAIN.

.DISCUSSION...
QUITE A POTPOURRI OF WEATHER TO LOOK AT TODAY. WEVE GOT
PRECIP...FRONTS AND MODEL DIFFERENCES. CONVECTION THIS AFTERNOON
IS ALREADY UP AND GOING IN THE MOUNTAINS...WELL PROBABLY SEE
SOME OF THE CONVECTION CREEP DOWN INTO THE LOWLANDS. SPEAKING OF
CREEPING THERE IS ALSO A COLD FRONT CREEPING SOUTH THROUGH THE
EAST PLAINS OF NEW MEXICO. THIS FRONT WILL WORK INTO THE AREA
DURING THE OVERNIGHT HOURS. THE FRONT WILL COOL OUR TEMPS A FEW
DEGREES AND IT MAY INCREASE OUR RAIN CHANCES. AND THAT IS WHERE
WE COME TO THE MODEL DIFFERENCES. THE NGM AND TO A LESSER EXTENT
THE WRF BRING THE MOISTURE PLUME THAT CURRENTLY SITS JUST TO OUR
SOUTHEAST...BACK OVER US. IF THE NGM IS TO BE BELIEVED WE ARE
GOING TO SEE ANOTHER WIDE SPREAD HEAVY RAIN EVENT FOR EL
PASO...BUT FOR NOW ILL LEAN TOWARD THE NAM AND GFS SOLUTION
WHICH DOES INCREASE OUR POPS...BUT DOESNT BRING IN WIDE SPREAD
HEAVY PRECIP FOR TUESDAY OR WEDNESDAY. FOR NOW ILL GO WITH THE
MIDDLE GROUND AND KEEP THE SCATTERED POPS FOR TUESDAY AND
WEDNESDAY AND LEAVE IT AT THAT. THE MIDDLE RANGE MODELS ALSO
DIFFER WITH THE GFS KEEPING THE MOISTURE PLUME WELL TO OUR SOUTH
WHILE THE DGEX KEEPS SOME MOISTURE IN THE AREA. I WILL TREND THE
POPS TOWARD THE DRIER SCENARIO...BUT NOT AS DRY AS THE GFS IS
INDICATING. FINALLY A SECOND COLD FRONT WILL PUSH INTO THE AREA
ON SUNDAY. THIS FRONT LOOKS STRONGER AND COOLER THAN TONIGHTS
FRONT. SO IVE DROPPED THE HIGHS ON SUNDAY AND WE COULD SEE SOME
INCREASED CHANCES FOR RAIN THEN.

TEMPERATURES TOMORROW AND WEDNESDAY WILL BE A FEW DEGREES BELOW
NORMAL BEHIND THE FIRST FRONT. TEMPERATURES WILL STRUGGLE BACK
TOWARD NORMAL FOR THE END OF THE WEEK INTO THE FIRST PART OF THIS
WEEKEND. THEN WILL SEE ANOTHER NOSE DIVE IN OUR HIGHS FOR NEXT
SUNDAY AS THE NEXT FRONT MOVES THROUGH.

Flash Flood

Flood
Flooding that develops more slowly than a flash flood: rivers leaving their banks, or water standing over land for an extended time.

After NWS Directive 10-1605, the rules offices file Storm Data by.
