AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EL PASO TX/SANTA TERESA NM
216 PM MDT WED JUL 9 2008

.SYNOPSIS...
ABUNDANT MOISTURE IN THE ATMOSPHERE WILL HELP GENERATE NUMEROUS
SHOWERS AND THUNDERSTORMS FOR THE NEXT COUPLE OF DAYS. HEAVY
RAINFALL IS EXPECTED FROM THESE SLOW MOVING STORMS. WITH THE
GROUND ALREADY SATURATED IN SOME AREAS FROM PREVIOUS RAINS...
EXCESSIVE RUNOFF WITH FLASH FLOODING WILL BE POSSIBLE. SOMEWHAT
DRIER CONDITIONS WILL OCCUR FOR LATE FRIDAY AND THE WEEKEND AS THE
PLUME OF MOISTURE SHIFTS FURTHER WEST AND HIGH PRESSURE BEGINS TO
BUILD OVER THE AREA. THERE WILL BE AT LEAST A SLIGHT CHANCE OF
THUNDERSTORMS NEXT WEEK WITH NEAR NORMAL TEMPERATURES.

&&

.DISCUSSION...
VERY MOIST CONDITIONS ARE PRESENT OVER THE FORECAST AREA. AN
INVERTED TROUGH JUST WEST OF THE AREA ALONG WITH A DOME OF HIGH
PRESSURE TO THE EAST IS HELPING CONCENTRATE A DEEP PLUME OF
MOISTURE OVER THE STATE FROM THE SOUTHWEST CORNER TO THE
NORTHEAST. CYCLONIC CIRCULATION INSIDE THE INVERTED TROUGH IS
INITIATING FURTHER RAIN AND THUNDERSTORM ACTIVITY DESPITE THE
OVERALL CLOUDY AND RAIN COOLED CONDITIONS. PRECIPITABLE WATER
VALUES ARE IN EXCESS OF 1.6 INCHES WHICH IS AROUND 17O TO 190
PERCENT OF NORMAL. THE VERY MOIST CONDITIONS FAVOR A CONTINUED
HEAVY RAIN PRODUCING EVENT THROUGH THURSDAY. A FLASH FLOOD WATCH
IS IN EFFECT THROUGH MIDNIGHT WHEN THE HEAVIEST RAIN IS EXPECTED
TO DIMINISH. THE POTENTIAL FOR HEAVY RAINFALL WILL OCCUR AGAIN
TOMORROW AND ANOTHER FLASH FLOOD WATCH WILL PROBABLY BE NEEDED.

MODELS SUGGEST THAT CONDITIONS WILL BECOME A BIT DRIER ON FRIDAY
BUT WILL STILL BE MOIST. PRECIPITABLE WATER VALUES WILL LOWER TO
BETWEEN 1.2 AND 1.4 WHICH IS STILL ABOVE NORMAL BUT THE HEAVY RAIN
THREAT WILL BE EASED SOMEWHAT. THE AXIS OF THE MOISTURE PLUME MAY
SHIFT A BIT FURTHER WEST ON FRIDAY AND SATURDAY...LESSENING
CHANCES FOR RAIN...EXCEPT FOR WESTERN ZONES FOR FRIDAY AND THE
WEEKEND. LATE IN THE WEEKEND THE THE HIGH TO THE EAST WILL BEGIN
TO RE-CENTER BACK TOWARD THE AREA AND WILL BE OVERHEAD THE
FORECAST AREA BY MONDAY. MODELS PROJECT THE HIGH TO REMAIN IN
PLACE FOR MUCH OF NEXT WEEK. THAT SAID THERE WILL BE CONSIDERABLE
MOISTURE TRAPPED UNDER THE HIGH THAT WILL BE ABLE TO FUEL
AFTERNOON AND EVENING THUNDERSTORMS EACH DAY WITH AFTERNOON
HEATING AND OROGRAPHIC LIFT.

&&

.AVIATION...VALID 10/00Z-11/00Z...
 PREDOMINANTLY VFR CONDITIONS THROUGH THE PERIOD. SHOWERS AND
THUNDERSTORMS WILL CAUSE LOWER CEILINGS AND VISIBILITIES...WITH
IFR AND LIFR CONDITIONS POSSIBLE. WINDS WILL GENERALLY BE LIGHT
EXPECT NEAR SHOWERS AND THUNDERSTORMS WHEN THEY MAY BECOME
ERRATIC.

&&

.FIRE WEATHER...
LOCALIZED FLOODING IS THE MAIN CONCERN DURING THE PERIOD AS RAINS
OVER THE PAST SEVERAL DAYS HAVE SATURATED THE GROUND. THE ATMOSPHERE
IS VERY MOIST AND THUS HEAVY RAIN WILL BE LIKELY WITH A MAJORITY OF
SHOWERS AND THUNDERSTORMS TODAY. WINDS WILL BE LIGHT WITH VERY GOOD
RELATIVE HUMIDITY RECOVERIES OVERNIGHT.
