NWS El Paso, TX wrote its last area forecast discussion before the first event at Aug 19, 1:33 PM MST, 3 hours 27 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE EL PASO TX/SANTA TERESA NM 233 PM MDT THU AUG 19 2010 .SYNOPSIS... A STRONG RIDGE OF HIGH PRESSURE REMAINS PARKED OVER THE SOUTHWEST U.S. THIS FEATURE WILL STAY OVER THE REGION THROUGH THE WEEKEND AND WELL INTO NEXT WEEK. THE RESULT WILL BE A CONTINUATION OF ABOVE NORMAL AFTERNOON TEMPERATURES WITH DESERT LOCATIONS IN THE UPPER 90S TO NEAR 100 EACH DAY. THE AIRMASS OVER THE BORDERLAND REMAINS MOIST AND THE HIGH PRESSURE ALOFT WILL KEEP THIS MOISTURE TRAPPED OVER THE REGION. STRONG HEATING EACH AFTERNOON WILL DESTABILIZE THE ATMOSPHERE AND LEAD TO SCATTERED MOUNTAIN AND ISOLATED LOWLAND SHOWERS AND THUNDERSTORMS EACH DAY. && .DISCUSSION... LITTLE TO NO CHANGE IN PATTERN FROM YESTERDAY AS A FLAT UPPER RIDGE OF HIGH PRESSURE REMAINS ENTRENCHED ALOFT ACROSS THE SOUTHERN TIER OF THE U.S. THE RIDGE AXIS IS ORIENTED WEST TO EAST RIGHT THROUGH THE HEART OF S NM AND FAR W TX. THIS APPEARS TO BE BUFFERING OUR REGION FROM A SHARP SHORTWAVE TRACKING EAST TO OUR NORTH...AND SMALLER IMPULSES TRACKING WEST TO OUR SOUTH. THUS NO SYNOPTIC SCALE FORCING MECHANISMS ARE EXPECTED TO MOVE OVER THE CWFA TO PRODUCED AN ORGANIZED OUTBREAK OF STORM DEVELOPMENT TODAY...OR IN THE NEXT FEW DAYS. THE AREA WILL HAVE TO RELY ON DAYTIME HEATING AND UPSLOPE MOUNTAIN FLOW TO DEVELOP THE LIFT NECESSARY TO BREAK THE CAP DUE TO WARM TEMPERATURES ALOFT. PROG SOUNDINGS DISPLAY LITTLE DIRECTION OR SPEED SHEAR IN THE VERTICAL WIND PROFILE...SO DON'T SEE ANY LONG- LIVED SEVERE STORM DEVELOPMENT. PW WAS AT 1.38 INCHES THIS MORNING...WHICH AGREES WELL WITH MODELS. STORM MOTION WILL BE FAIRLY SLOW SO THE COMBO OF FAIRLY DEEP MOISTURE AND SLOW STORMS WILL ALLOW FOR SOME STORMS WITH HEAVY RAIN AND SOME ISOLATED FLASH FLOOD POTENTIAL. LATER IN THE WEEK...THE GFS MODEL HINTS AT THE UPPER HIGH POSSIBLY SHIFTING POSITION TO THE NORTH AND THEN EAST. HOWEVER DIFFERENT RUNS ARE DOING DIFFERENT THINGS...SO NO CONFIDENCE IN THIS OUTCOME. IF THIS SHIFT IN THE HIGH DOES OCCUR IT COULD HELP TO PUSH THE MOISTURE WEST AND ALLOW SOME WAVES TO MOVE IN FROM THE EAST. THE OTHER FEATURE OF INTEREST IN THE MID RANGE IS A COLD FRONT THAT IS PROGED TO DROP IN LATE DAY TUESDAY. THIS SHOULD INCREASE STORM ACTIVITY ACROSS THE NORTHERN 2/3RDS OF NM AND POSSIBLY PROVIDE A FOCUS DOWN SOUTH ACROSS OUR AREA FOR INCREASED STORM. OTHERWISE JUST SCATTERED DAILY MOUNTAIN STORMS AND ISOLATED LOWLAND STORMS WITH ABOVE NORMAL TEMPERATURES EACH DAY. && .AVIATION...VALID 20/00Z-21/00Z... UPR LVL HI CONTINUES OVR RGN AS MSTR UNDER THE HIGH FUELS CONVECTION FROM DAY TIME HEATING. MNLY ISOLD TSRA XCPT LCLY SCT TSRA OVER MTNS THRU-19/04. ISOLD -TSRA AGAIN BTWN 20/18-20/24. LGT THERMAL CHOP ESP NR AREA MTNS. && .FIRE WEATHER... UPPER LEVEL HIGH PRESSURE WILL CONTINUE TO CONTROL THE WEATHER OVER THE AREA REGION THROUGH THE WEEKEND. MOISTURE TRAPPED UNDER THE HIGH WILL CONTINUE TO FUEL AFTERNOON AND NIGHT TIME THUNDERSTORM DEVELOPMENT. MOST FREQUENT STORM OCCURRENCE WILL BE OVER THE MOUNTAINS WITH MAINLY ISOLATED STORMS EXPECTED ELSEWHERE. LOCALLY HEAVY RAINFALL...SMALL HAIL...WIND GUSTS TO 50 MPH ARE POSSIBLE WITH ANY STORMS THAT DO OCCUR. BY LATE IN THE WEEKEND THE UPPER HIGH WILL ORIENT MORE NE-SW AS AN UPPER LEVEL TROUGH APPROACHES THE PACIFIC NORTHWEST. THIS WILL INCREASE MOISTURE OVER THE FORECAST AREA BRING AN INCREASED RISK OF THUNDERSTORMS. THEN AROUND NEXT TUESDAY A COLD FRONT WILL UNDERCUT THE UPPER HIGH AND HELP ORGANIZE THE STORMS...INCREASING THE RISK OF FLOODING AND SEVERE WEATHER. && .PRELIMINARY POINT TEMPS/POPS...

LOCALIZED FLOODING ALONG LOW WATER CROSSINGS AND DRAINAGES IS POSSIBLE. .DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY GENERAL WEATHER PATTERN WILL REMAIN MOSTLY UNCHANGED THROUGH THE PERIOD WITH HIGH PRESSURE OVER THE REGION. WARM TEMPERATURES AND TRAPPED MOISTURE WILL LEAD TO UNSTABLE ATMOSPHERIC CONDITIONS EACH AFTERNOON. THUS ISOLATED LOWLAND AND SCATTERED MOUNTAIN SHOWERS AND THUNDERSTORMS WILL CONTINUE THROUGH THE PERIOD. SOME STORMS MAY PRODUCE PERIODS OF HEAVY RAINFALL THAT MAY CAUSE MINOR LOCALIZED FLOODING ALONG LOW WATER CROSSINGS AND DRAINAGES. .SPOTTER INFORMATION STATEMENT...
