AREA FORECAST DISCUSSION  
NATIONAL WEATHER SERVICE EL PASO TX/SANTA TERESA NM  
350 AM MDT TUE JUN 25 2019  
   
SYNOPSIS
 
 
MOIST UNSTABLE AIR WILL FLOW INTO SOUTHERN NEW MEXICO AND WEST  
TEXAS OVER THE NEXT SEVEN DAYS UNDER HIGH PRESSURE ALOFT. THIS  
WEATHER PATTERN WILL PRODUCE A FEW MAINLY AFTERNOON AND EVENING  
SHOWERS AND THUNDERSTORMS ACROSS THE BORDERLAND EACH DAY.  
TEMPERATURES WILL REMAIN SEASONABLY WARM THROUGH THE PERIOD.  
 

 
   
DISCUSSION
 
 
A MONSOONAL WEATHER PATTERN WILL EXIST AT LOW LEVELS ACROSS THE  
WESTERN UNITED STATES THROUGH THE NEXT SEVEN DAYS. A LARGE AREA OF  
LOW PRESSURE ASSOCIATED WITH WARM TEMPERATURES WILL COVER MOST OF  
THE COUNTRY WEST OF THE DIVIDE WHILE HIGH PRESSURE EXTENDS INTO  
CENTRAL TEXAS. THIS SCENARIO WILL INDUCE A MOSTLY SOUTH TO  
SOUTHEAST FLOW ACROSS SOUTHERN NEW MEXICO AND WEST TEXAS  
BEGINNING OVER EASTERN PORTIONS OF THE CWA TODAY AND THEN  
SPREADING WESTWARD.  
 
LOW LEVEL MOISTURE WILL THEREFORE ADVECT INTO THE REGION WITH  
SURFACE DEWPOINTS INCREASING INTO THE 40S AND 50S CAUSING  
PRECIPITABLE WATER VALUES TO RISE TO AROUND .75 TO 1.1 INCH BY  
THURSDAY AFTERNOON. AMOUNTS SHOULD BE AROUND AN INCH ALMOST ALL  
LOCATIONS BY SATURDAY. COMBINATION OF SEASONABLY WARM SURFACE  
TEMPERATURES AND THE INCREASE IN MOISTURE WILL DESTABILIZE AIR  
MASS WITH AFTERNOON CAPE'S AROUND 500 TO 1000 J/KG AGAIN SPREADING  
EAST TO WEST THE NEXT FEW DAYS. THUS POTENTIAL FOR CONVECTION IS  
EXPECTED.  
 
INHIBITING AND LIMITING FACTOR WILL BE A RIDGE ALOFT WHICH WILL  
DEVELOP AND STRENGTHEN ACROSS THE SOUTHERN ROCKIES AND SOUTHERN  
PLAINS. BY THURSDAY THE RIDGE AXIS WILL EXTEND THROUGH THE CWA AND  
EXHIBIT LITTLE MOVEMENT INTO THE WEEKEND BEFORE SHIFTING SLOWLY  
TO THE WEST EARLY NEXT WEEK. THE RIDGE WILL BRING LARGE SCALE  
SUBSIDENCE ALOFT AND ALSO TEND TO BLOCK ANY DISTURBANCE ALOFT FROM  
ENTERING THE REGION MEANING THUNDERSTORMS INITIATION WILL DEPEND  
MAINLY ON SURFACE HEATING AND OUTFLOWS ACROSS THE LOWLANDS WITH  
UPSLOPE LIFT ENHANCING STORM FORMATION OVER HIGHER TERRAIN.  
OVERALL THIS SITUATION WILL KEEP STORM COVERAGE MAINLY ISOLATED  
LOWLANDS AND SCATTERED HIGHER MOUNTAINS. SEVERAL AREAS MAY STILL  
EXPERIENCE HEAVY RAINS GIVEN THE HIGH MOISTURE CONTENT. DCAPE'S  
ABOVE 1000 J/KG ALSO INDICATES A RISK OF STRONGER DOWNBURSTS.
