AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EL PASO TX/SANTA TERESA NM
132 PM MDT FRI SEP 1 2006

.SYNOPSIS...
SCATTERED SHOWERS AND THUNDERSTORMS WILL DEVELOP THIS AFTERNOON
AND TONIGHT AS A MOIST AND UNSTABLE AIR MASS REMAINS OVER THE
AREA. A STRONG COLD FRONT WILL MOVE INTO THE AREA TOMORROW WITH
COOLER TEMPERATURES...CLOUDY SKIES AND INCREASED CHANCES FOR RAIN
EXPECTED THROUGH SUNDAY NIGHT. A MOIST AND UNSTABLE AIR MASS WILL
REMAIN OVER THE REGION FOR MUCH OF NEXT WEEK WITH A CHANCE OF
SHOWERS AND THUNDERSTORMS EACH DAY.

&&

.DISCUSSION...
AN ACTIVE AND WET PATTERN WILL CONTINUE OVER SOUTHERN NEW MEXICO
AND FAR WEST TEXAS THROUGH MOST OF NEXT WEEK. MOISTURE MOVING UP
FROM THE SOUTH WILL FUEL SCATTERED SHOWERS AND THUNDERSTORMS THIS
AFTERNOON AND TONIGHT. SOME OF THE STORMS WILL PRODUCE HEAVY RAIN
WITH LOCALIZED FLOODING POSSIBLE. SOUTHERLY CIRCULATION ALONG THE
EAST SIDE OF HURRICANE JOHN WILL PULL ADDITIONAL MOISTURE UP OVER
THE REGION BY TOMORROW AND CONTINUE THAT TREND FOR THE NEXT FEW
DAYS.

A STRONG COLD FRONT WILL PUSH INTO THE STATE TOMORROW. BESIDES
GENERATING STRONG EAST SURFACE WINDS AND MUCH COOLER TEMPERATURES
THE FRONT WILL PROVIDE ADDITIONAL LIFT TO THE WARMER AND MORE
MOIST AIR MASS ABOVE IT TO GENERATE ADDITIONAL RAIN FOR THE LATTER
PART OF SATURDAY THROUGH SUNDAY NIGHT. A LOT OF THE RAIN MAY BE
STRATIFORM IN NATURE...PUNCTUATED BY A SCATTERED THUNDERSTORMS
HEAR AND THERE. MODEL QPFS ARE FAIRLY HIGH WITH A LARGE PORTION
OF THE FORECAST AREA SEEING ONE TO THREE INCH ACCUMULATIONS DURING
THE EVENT. FLOODING WILL BE A CONCERN... ESPECIALLY FOR AREAS
PREVIOUSLY FLOODED BY PAST RAIN EVENTS. SUNDAY COULD BE VERY
CLOUDY...COOL AND RAINY FOR MUCH OF THE AREA.

MONDAY MAY SEE A LITTLE LESS ACTIVITY AS THE FRONT PUSHES FURTHER
SOUTH AND MORE STABLE AIR MOVES IN. MODELS ARE NOT QUITE IN
AGREEMENT ON WEATHER CONDITIONS WILL BECOME MORE STABLE. HURRICANE
JOHN OR ITS REMNANTS WILL STILL BE A FACTOR...CONTRIBUTING MORE
MOISTURE TO THE REGION FROM THE WEST. THE GFS MODEL PROJECTS JOHN
TO MOVE INLAND TO SOUTHERN ARIZONA BY TUESDAY. MUCH OF THE
MOISTURE FROM THAT SYSTEM WILL BE EAST OF THE CENTER OF THE STORM
AND COULD AFFECT THE FORECAST AREA WITH ADDITIONAL HEAVY RAINFALL
THROUGH WEDNESDAY. THE REMNANTS OF HURRICANE JOHN WILL FORM AN
OPEN TROUGH BY THURSDAY AND MOVE THROUGH THE REGION WITH
ADDITIONAL SHOWERS AND THUNDERSTORMS. CONDITIONS SHOULD DRY OUT
TOWARD NEXT FRIDAY AS THE TROUGH MOVES EAST AND A MORE STABLE
NORTHWEST FLOW TAKES HOLD OVER THE AREA.

&&

.AVIATION...VALID 02/00Z-03/00Z
GENERALLY VFR CONDITIONS WITH WIDELY SCATTERED AREAS OF MVFR AND
OCCASIONAL IFR FOR CIGS/VSBY NEAR AFTERNOON AND NIGHT TIME
THUNDERSTORMS. RAIN AND THUNDERSTORMS WILL INCREASE AND CEILINGS
WILL BEGIN LOWER BY LATE TOMORROW AS A COLD FRONT MOVES INTO THE
AREA. SEE APPROPRIATE TAF AND TWEBS FOR FURTHER INFORMATION.
