AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE EL PASO TX/SANTA TERESA NM 100 PM MDT TUE AUG 24 2010 .SYNOPSIS... SCATTERED SHOWERS AND THUNDERSTORMS WILL OCCUR ACROSS THE BORDERLAND LATE THIS AFTERNOON AND THIS EVENING BEHIND A COLD FRONT WHICH MOVED ACROSS THE REGION. HIGH PRESSURE WILL BRING SEASONABLY WARM MOSTLY DRY WEATHER WEDNESDAY THROUGH FRIDAY. A LOW PRESSURE SYSTEM APPROACHING FROM THE WEST WILL PULL MOIST AIR INTO THE BORDERLAND THIS WEEKEND AND EARLY NEXT WEEK RESULTING IN MORE WIDESPREAD SHOWER AND THUNDERSTORM ACTIVITY. && .DISCUSSION... A RATHER STRONG COLD FRONT MOVED THROUGH THE CWA THIS MORNING WITH NORTHEAST WINDS BEHIND THE BOUNDARY ADVECTING COOLER BUT STILL MOIST AIR MASS. SOUNDINGS SHOWED PRECIPITABLE WATER NEAR 1.5 INCHES ALONG WITH AN IMPRESSIVE 2500 J/KG CAPE INDICATING POTENTIAL FOR DEEP CONVECTION. SHORT TERM MODEL OUTPUT PLUS SATELLITE IMAGES ALSO SHOW WEAK VORTICITY AXIS ALOFT MOVING INTO THE CWA FROM THE NORTHEAST. THUS EXPECT CONVECTION TO CONTINUE INTO THIS EVENING. DEEP MOISTURE AND INSTABILITY PLUS WEAK FLOW ALOFT INDICATE PRIMARY WEATHER THREAT WILL BE SLOW MOVING AND/OR BACK BUILDING CELLS PRODUCING LOCALLY HEAVY RAINS. WEDNESDAY AND THURSDAY STRONG UPPER RIDGE AXIS WILL BE NORTHWEST OF THE CWA WITH MID LEVEL FLOW FROM THE NORTHEAST TRANSPORTING WARM DRY AIR ALOFT INTO THE AREA.

THUS MOSTLY DRY WEATHER EXPECTED WITH TEMPERATURES SLOWLY WARMING. FRIDAY AND BEYOND RATHER DEEP HIGH AMPLITUDE UPPER TROUGH WILL DRIFT VERY SLOWLY EASTWARD ACROSS THE WESTERN UNITED STATES WHILE RIDGE ALOFT BECOMES ESTABLISHED FURTHER EAST. THIS PATTERN WILL INDUCE DEEPENING SOUTHERLY WIND COMPONENT FROM FRIDAY THROUGH SUNDAY WITH ABUNDANT MOISTURE FLOWING BACK INTO THE CWA. PRECIPITABLE WATER SHOULD INCREASE AROUND 1.3 TO 1.5 INCHES BY SUNDAY AFTERNOON WHILE AIR MASS DESTABILIZES DUE TO WARM MOIST AIR AT LOW LEVELS AND SLIGHT COOLING ALOFT AHEAD OF TROUGH. THESE FACTORS SHOULD RESULT IN STRONGER MORE WIDESPREAD CONVECTION SPREADING WEST TO EAST THIS WEEKEND WITH AT LEAST SCATTERED SHOWERS AND THUNDERSTORMS EARLY NEXT WEEK. && .AVIATION...VALID 25/00Z-26/00Z...
