AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EL PASO TX/SANTA TERESA NM
257 PM MDT TUE SEP 16 2014

.SYNOPSIS...
THE BORDERLAND IS CERTAIN TO GET MORE RAIN...AND A LOT OF
IT...TONIGHT THROUGH THURSDAY EVENING AS THE REMNANTS OF FORMER
HURRICANE ODILE SLOWLY TRACKS ACROSS THE SOUTHWESTERN U.S.
WEDNESDAY AND THURSDAY. VERY DEEP TROPICAL MOISTURE AND
INSTABILITY ASSOCIATED WITH THE STORM WILL BRING WIDESPREAD AND
NUMEROUS SHOWERS AND EMBEDDED THUNDERSTORMS TO THE REGION. FLASH
FLOODING...SOME OF IT SERIOUS IS EXPECTED...AND THE AREA IS UNDER
A FLASH FLOOD WATCH THROUGH THURSDAY NIGHT. WITH THE COPIOUS RAIN
AND CLOUDS...TEMPERATURES CONTINUE TO RUN BELOW NORMAL THROUGH
THE END OF THE WEEK. DRIER CONDITIONS WILL RETURN LATER IN THE DAY
FRIDAY AS THE SYSTEM EXITS THE REGION...HOWEVER RESIDUAL MOISTURE
WILL HANG BACK AND KEEP THE POTENTIAL FOR SHOWERS AND THUNDERSTORM
IN PLAY ACROSS THE AREA THROUGH THE WEEKEND AND INTO NEXT WEEK.

&&

.DISCUSSION...
PLENTY OF WEATHER FEATURES TO WATCH FOR THE NEXT 72 HOURS. FORMER
HURRICANE ODILE CONTINUES TO SLOWLY TRACK NORTH IN THE GULF OF
CALIFORNIA JUST OFF THE BAJA. WE SIT IN A DEEP AND VERY MOIST
SOUTHERLY FLOW PATTERN ON THE STORMS WET EAST SIDE. PW'S ARE OVER
1.65" WITH A MAX OF NEAR 1 3/4" EXPECTED OVER THE AREA TONIGHT
THROUGH MIDDAY THURSDAY. THIS PUTS OUR AREA JUST BELOW THE RECORD
LEVELS FOR MID-SEPTEMBER PW. THE STORM ITSELF WILL CONTINUE IT'S
TRACK NORTH AND A LITTLE EAST TOWARD SOUTHERN AZ...JUST SW OF
TUCSON, AZ. THE CENTER IS PROGED TO CROSS INTO THE U.S. LATE WED
EVENING...AND TRACK OVER THE GILA AND INTO CENTRAL NM ON THURSDAY.
THIS IS THE SET UP FOR THE ANTICIPATED WEATHER THE NEXT 72 HRS.

THIS AFTERNOON WE SEE CONVECTIVE STORM DEVELOPMENT TO OUR SOUTH
OVER NORTHERN CHIHUAHUA IN THE REGION WITH BETTER SUNSHINE. THE
STORM MOTION IS TO THE NORTH SO WE ANTICIPATED AN INCREASE IN
STORM AND SHOWER ACTIVITY THIS EVENING AND TONIGHT FROM THE SOUTH.
AIDING THIS DEVELOPMENT IS ANOTHER SPOKE OF ENERGY AND DEEP
MOISTURE SURGE WITH ANOTHER ODILE BAND. THIS SPOKE WILL LIKELY
MOVE OVER THE CWFA IN THE LATE EVENING AND OVERNIGHT HOURS BEFORE
SUNRISE. OVERALL RAINFALL RATES OF .3 TO .75" PER HOUR IS EXPECTED
BUT THE THUNDERSTORM CELLS WILL BE CAPABLE OF 2X TO 3X THOSE
RATES...AND WILL LIKELY CAUSE FLOODING ISSUES TONIGHT.

LIKE WE DID TODAY...WE MIGHT SEE A BREAK IN THE WIDESPREAD RAIN
DURING THE DAYTIME HOURS ON WEDNESDAY. HOWEVER IN THE MID
AFTERNOON HOURS AND MORE SO AS WE GO INTO THE OVERNIGHT HOURS WE
ARE LOOKING AT THE POTENTIAL FOR A SIGNIFICANT INCREASE IN RAIN
ACTIVITY STARTING OVER WESTERN ZONES IN THE BOOTHEEL AND GILA AS
ODILE BEGINS TO NEAR THE REGION FROM THE WEST. OVERNIGHT TOWARDS
THURSDAY MORNING WE SHOULD SEE THIS AREA OF WIDESPREAD HEAVY RAIN
MOVE EAST ACROSS THE NORTHERN ZONES. WE HAVE CONTINUED THE TREND
OF INCREASE BOTH THE CHANCES OF PRECIPITATION AND THE AMOUNT OF
PRECIPITATION EXPECTED. THUS POPS IN THE 80-100% PROBABILITY ARE
COMMON AND STORM TOTAL PRECIP AMOUNTS ARE IN THE 1-3" RANGE
EAST...2-4" CENTRAL...3-5" WESTERN LOWLANDS...4-6" AREA MOUNTAINS.
THERE WILL BE GREAT VARIABILITY IN THE PCPN AMOUNT ACROSS THE
REGION AND GREATER AMOUNTS UP TO 8-9" OVER LOCAL AREAS WILL BE
POSSIBLE. THOSE GREATER AMOUNTS WILL LIKELY BE OVER AREAS MTNS.
NEEDLESS TO SAY WE CONTINUE THE FLASH FLOOD WATCH...AND EXTEND IT
THROUGH THURSDAY NIGHT AT MIDNIGHT. OF SPECIAL NOTE WILL BE THE
POTENTIAL FOR RIVER AND STREAM FLOODING ACROSS THE REGION.

FRIDAY THE SYSTEM WILL BE TO OUR NORTH AND WILL BEGIN TRACKING
EAST OUT OF THE SOUTHERN ROCKIES INTO THE CENTRAL PLAINS. WE
SHOULD SEE DIMINISHING RAIN COVERAGE FROM WEST TO EAST DURING THE
DAY. DRIER AIR IN WESTERLY AIR BEHIND THE SYSTEM WILL MOVE OVER
THE REGION LATE FRI AND THROUGH THE WEEKEND. WE WON'T TOTALLY DRY
OUT THE AIRMASS SO WE'LL KEEP CHANCES FOR ISOLATED LOWLAND AND
SCATTERED MOUNTAIN SHOWERS AND STORMS OVER THE AREA THROUGH THE
WEEKEND.

NEXT WEEK WE WILL BE WATCHING YET ANOTHER TROPICAL SYSTEM
ATTEMPTING TO CRAWL UP THE BAJA...MUCH LIKE NORBERT DID. IT COULD
GIVE US ANOTHER PERIOD OF INCREASED MOISTURE AND RAIN CHANCES FOR
NEXT WEEK.

.AVIATION...VALID 17/00Z - 18/00Z...
AN IMPULSE ROTATING SLOWLY UP AROUND TROPICAL THE EASTERN SIDE OF

WEST TX THROUGH 18Z WEDNESDAY. SKIES WILL BECOME PARTLY TO MOSTLY
CLOUDY WED AFTERNOON.  LOOK FOR LOWLAND CLDS SCT 010-020 BKN-OVC
CIGS TO 030-050 AGL...WITH SCT VIS TO 3 SM IN -SHRA/SHRA AND TSRA.
CIGS TO 005 NEAR MTNS OVER LOWLANDS.  LOOK FOR LIFR BKN MTN
OBSCURATIONS THROUGH PD. EXPECT GENERALLY LIGHT TURBC OUTSIDE
STORMS. WINDS WILL BE FROM ENE-SE AROUND 06-09 KTS.

22-TRIPOLI

.FIRE WEATHER...
MODELS ARE NOW IN MUCH BETTER AGREEMENT IN FOREASTING TRACK OF NOW
TROPICAL STORM ODILE OVER ARIZONA WEDNESDAY AND THURSDAY.  FEATURE

EAST INTO ARIZONA...THEN EAST NORTHEAST INTO WESTERN NM.  RAINFALL
