Flash Flood Warning 23, NWS Albuquerque, NM

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ALBUQUERQUE NM
303 PM MDT TUE AUG 11 2009

.DISCUSSION...
20Z SURFACE ANALYSIS INDICATES A FRONTAL BOUNDARY DRAPED ALONG THE
EAST SLOPES OF THE CENTRAL MTN CHAIN...WITH DEWPOINT VALUES IN THE
50S TO THE EAST OF THE BNDRY AND GRADUALLY FALLING INTO THE TEENS
FARTHER WEST ALONG THE AZ STATE LINE. VIS SAT IMAGERY SHOWS STORMS
FIRING ALONG THE BOUNDARY AND EVEN A LITTLE MORE OVER THE GILA THAN
MONDAY. THE 600-350MB ACARS WIND PLOT INDICATES THE UPPER TROUGH
OVER THE GREAT LAKES REGION HAS PULLED EAST ALLOWING THE 596DM H5
DOME OF HIGH PRESSURE TO REBUILD OVER SOUTHERN NM. 150-200 PERCENT
OF NORMAL PWAT VALUES OVER THE BAJA/SONORA REGION ARE PULLING NORTH
INTO SOUTHERN AZ. 12Z NAM/GFS/ECMWF 700-500MB STREAMLINE ANALYSIS
ALONG WITH THE 12Z GFS BUFKIT PROFILE AT GALLUP SHOWS ATMOSPHERIC
FLOW WILL BECOME MORE SOUTHERLY AND NEAR SATURATED OVER WESTERN NM
THRU WEDNESDAY EVENING...THEN SPREAD EAST TOWARD THE CENTRAL VALLEYS
AS THE H5 DOME EVOLVES INTO A MORE ELONGATED RIDGE OVER EASTERN NM.
RAISED POPS TO SOLID CHANCE OVER MUCH OF THE WEST INTO THURSDAY EVE.

ENSEMBLE GUIDANCE INDICATES WITH LOW SPREAD AN UPPER WAVE WILL MOVE
SLOWLY EAST INTO THE NORTHERN ROCKIES FROM BRITISH COLUMBIA AND
ALLOW SOUTH TO SW FLOW TO INCREASE OVER THE SW CONUS AS THE RIDGE
EXPANDS EAST INTO TX. THIS WILL ADVECT ABUNDANT LOW LEVEL MOISTURE
INTO THE SOUTHWEST CONUS. NAM/GFS PWAT VALUES INDICATE 1-1.5 VALUES
CROSSING THE STATE FROM LATE THURS THROUGH EARLY SATURDAY. RAISED
POPS AGAIN TO SOLID CHANCE FOR MUCH OF THE REGION. THE WESTERN HALF
OF THE STATE HAS BEEN VERY DRY AND MODERATE SW FLOW SHOULD LIMIT THE
FLASH FLOOD THREAT. MODELS DO INDICATE A VORT MAX WILL ATTEMPT TO
SLIDE NE WITH THE MOIST PLUME FRIDAY WHICH MAY BE ENOUGH FOR AT
LEAST SOME MINOR FLOODING ACROSS CENTRAL NM.

EXTENDED GUIDANCE DOES INDICATE DRIER SW FLOW INCREASING OVER AT
LEAST THE WESTERN HALF LATE SATURDAY INTO SUNDAY. DIFFERENCES DO
ARISE INTO EARLY NEXT WEEK REGARDING THE STRENGTH OF AN UPPER
WEAKNESS ATTEMPTING TO PINCH OFF OVER THE DESERT SW AS THE MAIN
TROUGH AXIS SLIDES TO OUR NE. THE STRONGER ECMWF SOLUTION PULLS
MORE MOISTURE OUT OF OLD MEXICO AHEAD OF THE WEAKNESS...CONTINUING
ISOLD/SCT CHANCES OF PRECIP NEXT WEEK. GUYER

&&

.AVIATION...
SHOWERS AND THUNDERSTORMS WILL CONTINUE TO DEVELOP ALONG THE CENTRAL
MTN CHAIN THIS AFTERNOON AND MOVE EASTWARD ONTO THE PLAINS. A FEW
TSTMS MAY RESULT IN SFC WIND GUSTS TO 50KT AND LARGE HAIL. SITES
THAT MAY BE IMPACTED INCLUDE KTCC...KROW AND KLVS...BUT TIMING
REMAINS UNCERTAIN. THEREFORE... USE OF CB AND VCTS IN TAF INDICATES
THUNDERSTORMS IN GENERAL AREA BUT UNCERTAINTY IN COVERAGE OR TIMING
AT AIRPORT. MVFR CEILING AND VISIBILITIES ARE ALSO POSSIBLE WITH
TSTMS. TSTM COVERAGE IS EXPECTED TO DIMINISH AROUND 06Z. AREAS WEST
OF THE CENTRAL MTN CHAIN WILL REMAIN IN VFR CONDITIONS THROUGH THE
OVERNIGHT HOURS...THOUGH MID AND UPPER LEVEL CLOUD COVER WILL
INCREASE.

NEXT AVIATION DISCUSSION SCHEDULED FOR 09Z. 34

&&

.FIRE WEATHER...
SHOWERS AND THUNDERSTORMS HAVE ERUPTED FROM THE SANDIA AND MANZANO
MOUNTAINS SOUTHWARD...AND TO A LESSER EXTENT...ACROSS THE SANGRE DE
CRISTO MOUNTAINS. THE ADDITIONAL THUNDERSTORM COVERAGE ACROSS
CENTRAL NM TODAY IS THANKS TO A FRONT THAT BROUGHT ADDED MOISTURE TO
THE AREA THIS MORNING. ADDITIONAL STORMS ARE EXPECTED ACROSS THE
PLAINS THIS EVENING...HOWEVER...WETTING RAIN FOOTPRINTS SHOULD BE
FAIRLY SMALL.  MEANWHILE...RELATIVE HUMIDITIES HAVE DROPPED BELOW 10
PERCENT ACROSS MUCH OF WESTERN NEW MEXICO. RELATIVE HUMIDITY
RECOVERY SHOULD BE SOMEWHAT BETTER TONIGHT THAN LAST NIGHT IN THESE
AREAS AS MOISTURE IS ADVECTED INTO THE AREA FROM EAST AND SOUTHEAST
WINDS THROUGH THE GAPS OF THE CENTRAL MOUNTAIN CHAIN.

THE UPPER HIGH REMAINS OVER THE STATE ON WEDNESDAY...RESULTING IN
CONTINUED ABOVE NORMAL TEMPERATURES. DESPITE THE MOISTURE PUSH
OVERNIGHT...DAYTIME RELATIVE HUMIDITIES WILL STILL FALL BELOW 15
PERCENT ACROSS MUCH OF NORTHWEST NM WITH HIGH HAINES.  SHOWER AND
THUNDERSTORM COVERAGE IS EXPECTED TO INCREASE ACROSS THE WEST
CENTRAL AND SOUTHWEST MTNS...WHILE SIMILAR COVERAGE IS EXPECTED
ACROSS THE EAST.

AS THE HIGH SHIFTS SOUTHEAST ON THURSDAY AND FRIDAY...LOOK FOR
WETTER CONDITIONS TO DEVELOP ACROSS THE STATE. SOUTHWEST FLOW ALOFT
WILL HELP TO TRANSPORT MOISTURE OVER NM...AND WETTING RAINS
ARE EXPECTED EACH DAY. ISOLATED ACTIVITY IS STILL EXPECTED ON
SATURDAY...BUT MUCH DRIER CONDITIONS ARE FORECAST FOR SUNDAY. 34
