AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EL PASO TX/SANTA TERESA NM
256 PM MDT MON JUL 11 2011

.SYNOPSIS...
A DEEP PLUME OF MOISTURE WILL BE IN PLACE OVER THE STATE FOR THE
NEXT FEW DAYS. CLOUDY SKIES WITH SCATTERED TO NUMEROUS SHOWERS AND
THUNDERSTORMS WILL DEVELOP ACROSS THE LOCAL AREA. LOCALLY HEAVY
RAINFALL WILL BE POSSIBLE THROUGH WEDNESDAY. A REDUCTION IN
MOISTURE WILL TOWARD THE END OF THE WEEK WILL REDUCE CHANCES FOR
THUNDERSTORMS BACK TO ISOLATED FOR MOST AREAS THURSDAY THROUGH
SATURDAY. THE PLUME OF MOISTURE WILL SHIFT BACK WEST OF THE AREA
BY LATE SUNDAY INTO THE FIRST PART OF NEXT WEEK.

&&

.DISCUSSION...
WITH A THE HIGH SHIFTING TO THE EAST AND A WEST COAST TROUGH
DEEPENING...THE PLUME OF MOISTURE THAT HAD BEEN OVER ARIZONA IS
NOW SHIFTING EASTWARD INTO NEW MEXICO. THIS DEEPER MOISTURE WILL
RESULT IN SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS THIS
AFTERNOON THROUGH WEDNESDAY NIGHT. THE AVAILABLE MOISTURE WILL
DEEPEST ON TUESDAY WITH PRECIPITABLE WATER VALUES EXPECTED TO NEAR
170 PERCENT OF NORMAL. THAT INDICATES THAT ANY STORMS THAT FORM
WILL BE EFFICIENT RAIN PRODUCERS WITH LOCALLY HEAVY RAINFALL
POSSIBLE. EXCESSIVE RUN OFF FROM HEAVY RAIN MAY CAUSE MINOR
LOCALIZED FLOODING ALONG DRAINAGES AND LOW LYING AREAS. IN
ISOLATED CASES WHERE RAIN AMOUNTS ARE MUCH HIGHER...LOCALIZED
FLASH FLOODING MIGHT OCCUR.

BY THURSDAY...THE HIGH WILL BEGIN TO REFORM CLOSER BACK TO THE
LOCAL AREA. THIS CHANGE WILL START TO DIMINISH THE FLOW OF
MOISTURE ACROSS THE AREA AND REDUCE THE FREQUENCY OF SHOWERS AND
THUNDERSTORMS FOR THE LATTER PART OF THE WEEK. MAINLY ISOLATED
LOWLAND AND SCATTERED MOUNTAIN THUNDERSTORMS ARE EXPECTED THURSDAY
THROUGH SATURDAY. TEMPERATURES WILL ALSO BEGIN TO WARM BACK UP
ABOVE NORMAL INTO THE UPPER 90S TO NEAR 100 FOR THE LOWLANDS.

BY SUNDAY THE HIGH WILL BE CENTERED OVER THE NORTHERN PART OF THE
STATE WITH AN EASTERLY FLOW PATTERN SET UP OVER THE LOCAL AREA.
THIS FLOW WILL TAP MAINLY DRIER CONTINENTAL AIR WHICH WILL FURTHER
REDUCE MOISTURE ACROSS THE REGION AND DIMINISH THUNDERSTORM
CHANCES TO NEAR ZERO EXCEPT FOR THE MOUNTAIN ZONES FOR SUNDAY
THROUGH NEXT TUESDAY. TEMPERATURES WILL CONTINUE TO BE ABOVE
NORMAL.

&&

.AVIATION...VALID 12/00Z-13/00Z...
PREVAILING SCT080-150 BKN250 CAN BE EXPECTED THRU PD WITH SE
WINDS 6-12KTS. SCT TSRA WITH BKN040-060 WILL LINGER UNTIL 08Z AND
START AGAIN AFT 17Z...WDLY SCT TO SCT 3-5SM TSRA BKN040-060
EXPECTED.

&&

.FIRE WEATHER...
SHOWER AND THUNDERSTORM COVERAGE WILL INCREASE ACROSS THE REGION
OVER THE NEXT 2 TO 3 DAYS AS A BROAD UPPER LOW MOVES EAST OF THE
AREA TODAY...AND ANOTHER UPPER DISTURBANCE OVER NORTHWEST MEXICO
MOVES INTO THE AREA...CARRYING ENHANCED SUBTROPICAL MOISTURE WITH
IT.  LATER IN THE WEEK...A DEEPENING TROUGH OVER THE WEST COAST
WILL SHIFT THE SUBTROPICAL RIDGE EASTWARD...AND WHILE THE OVERALL
MOISTURE AVAILABILITY AND PRECIP COVERAGE WILL DECREASE...THE
MONSOONAL MOISTURE PLUME WILL FAVOR AREAS NEAR AND EAST OF THE
CONTINENTAL DIVIDE HEADING INTO THE WEEKEND.  THE RESULT WILL BE
INCREASING PRECIPITATION...ESPECIALLY OVER THE HIGHER TERRAIN
AREAS.
