AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EL PASO TX/SANTA TERESA NM
258 PM MDT MON JUL 9 2012

.SYNOPSIS...
ISOLATED THUNDERSTORMS WILL CONTINUE TONIGHT AS ENOUGH LOW LEVEL
MOISTURE AND INSTABILITY PERSIST. A COOL FRONT PUSHES IN FROM THE
EAST LATE TONIGHT. THIS WILL INCREASE THE MOISTURE AND INSTABILITY
FURTHER ON TUESDAY AND WEDNESDAY...INCREASING THE COVERAGE OF
THUNDERSTORMS. THE HIGHER MOISTURE LEVELS WILL ALSO CREATE THE
POSSIBILITY OF HEAVY RAIN AND LOCAL FLOODING. BY THURSDAY THE UPPER
RIDGE RE DEVELOPS OVER NORTHERN NEW MEXICO. THIS SHOULD DECREASE
THUNDERSTORM COVERAGE BACK TO ISOLATED AND ALSO ALLOW TEMPERATURES
TO WARM BACK ABOVE NORMAL.

&&

.DISCUSSION...
DECENT OROGRAPHIC CONVECTION FIRING OFF THIS AFTERNOON AS DEW POINTS
REMAIN IN THE UPPER 40S TO MID 50S. MEANWHILE LARGE UPPER HIGH OVER
THE GREAT BASIN CONTINUES MODERATE NORTHERLY FLOW OVER THE CWA. THIS
WILL RESULT IN BRINGING A LARGE VORT MAX DOWN OVER EASTERN NEW
MEXICO TONIGHT. THIS WILL ALLOW A BACK DOOR COOL FRONT TO PUSH INTO
THE EASTERN CWA TONIGHT AND LIKELY TO THE ARIZONA BORDER BY DAYBREAK
TUESDAY. THIS SHOULD HELP INCREASE SHOWERS ACROSS THE FAR EAST
TONIGHT AND THEN ALL AREAS TUESDAY. THE DRAWBACK ON TUESDAY IS THAT
HIGH TEMPERATURES WILL BE ABOUT 5 TO 10 DEGREES COOLER THAN
TODAY...PERHAPS BARELY REACHING CONVECTIVE TEMPS. BUT THE FRONTAL
LIFT AND VORT CENTER ALOFT SHOULD MAKE UP FOR THIS. TPW PRODUCT
SHOWS PW'S CURRENTLY AROUND 1.2 INCHES AND MODELS CONTINUE TO SHOW
THEM INCREASING TO AROUND 1.5 INCHES TOMORROW. WITH THE MOISTURE AND
INSTABILITY...THUNDERSTORM COVERAGE SHOULD INCREASE SIGNIFICANTLY
TUESDAY AND WEDNESDAY. HEAVY RAINFALL AND LOCAL FLOODING WILL BE THE
MAIN THREATS BOTH TUESDAY AND WEDNESDAY. NAM DOES SHOW VORT CENTER
SOUTH OF THE AREA WEDNESDAY SO STILL SOME DOUBT ABOUT HOW WIDESPREAD
SHOWERS/THUNDERSTORMS WILL BE ON WEDNESDAY.

THURSDAY INTO THE WEEKEND...UPPER HIGH GRADUALLY BUILDS DOWN TO THE
FOUR CORNERS AND NORTHERN NEW MEXICO AND ELONGATING EAST-WEST. THIS
WILL MEAN BY THURSDAY AND BEYOND WE WILL BE UNDER A DRIER
EAST/NORTHEAST FLOW. THUNDERSTORM COVERAGE WILL DECREASE BACK TO
ISOLATED AND MOST OF THESE SHOULD REMAIN OVER MOUNTAIN AREAS. AFTER
A COUPLE OF DAYS OF BELOW NORMAL TEMPERATURES...THEY SHOULD REBOUND
BACK TO NORMAL OR ABOVE NORMAL BY FRIDAY.

&&

.AVIATION....VALID 10/00Z-11/00Z.
UPPER LEVEL TROUGH AND ASSOCIATED SURFACE COLD FRONT WILL BRING A
SIGNIFICANT INCREASE IN SHOWER AND THUNDERSTORM ACTIVITY TONIGHT
AND TUESDAY. ISOLD LOWLAND +TSRA/SCT MTN +TSRAGS THIS EVENING THEN
SCT TO NUMEROUS TSTMS OVERNIGHT AND TUESDAY. EXPECT WIND VRB25G45KT
AND VSBY LESS THAN 1SM IN STORMS WITH LOCALLY HEAVY RAIN. CIGS
FEW-SCT010-020 SCT-BKN030-050 BKN-OVC080-120 OVERNIGHT AND TUESDAY.

&&

.FIRE WEATHER...
HIGH PRESSURE ALOFT OVER THE INTER-MOUNTAIN WEST HAS SUPPRESSED
THUNDERSTORM ACTIVITY THE PAST FEW DAYS BY PUSHING RELATIVELY DRY
AND STABLE AIR IN FROM THE NORTHEAST. HOWEVER...AN UPPER LEVEL
TROUGH AND ASSOCIATED SURFACE COLD FRONT WILL PUSH SOUTHWEST ACROSS
NEW MEXICO TONIGHT THEN BECOME STATIONARY ALONG THE ARIZONA BORDER
TOMORROW. THIS WILL BRING A SURGE OF MOIST AND UNSTABLE AIR TO THE
REGION THAT MAY LEAD TO INCREASED SHOWER AND THUNDERSTORM ACTIVITY
WITH THE POTENTIAL FOR HEAVY RAIN AND FLOODING TONIGHT THROUGH
WEDNESDAY. DRAINAGES ACROSS THE LITTLE BEAR AND THE WHITEWATER-BALDY
BURN SCARS WILL BE ESPECIALLY PRONE TO FLASH FLOODING. MINIMUM
HUMIDITY WILL BE ABOVE 30 PERCENT THE NEXT COUPLE OF AFTERNOONS WITH
EXCELLENT OVERNIGHT RECOVERY. WINDS MOSTLY LIGHT THE NEXT FEW DAYS.
THAT HIGH PRESSURE ALOFT IS EXPECTED TO SHIFT EASTWARD ACROSS THE
FOUR CORNERS AREA BY THURSDAY...LOWERING THE CHANCE FOR SHOWERS AND
THUNDERSTORMS.
