NWS El Paso, TX wrote its last area forecast discussion before the first event at Jul 24, 2:43 AM MST, 11 hours 2 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE EL PASO TX/SANTA TERESA NM 343 AM MDT SUN JUL 24 2011 .SYNOPSIS... MOIST UNSTABLE AIR WILL FLOW INTO SOUTHERN NEW MEXICO AND WESTERN TEXAS TODAY AND MONDAY WHILE AN UPPER LEVEL DISTURBANCE MOVES INTO THE REGION FROM THE EAST. AS A RESULT THERE WILL BE GOOD CHANCES FOR THUNDERSTORMS WITH A FEW STORMS PRODUCING LOCALLY HEAVY RAINS AND FLOODING. HIGH PRESSURE ALOFT WILL CAUSE SOME DECREASE IN THUNDERSTORM COVERAGE THE REMAINDER OF THE WEEK. && .DISCUSSION... AIR MASS REMAINS MOIST AND UNSTABLE ACROSS THE CWA AS SOUTHERN NEW MEXICO AND WESTERN TEXAS REMAIN LOCATED SOUTH OF A BROAD EAST TO WEST ORIENTED RIDGE. THUS DEEP SOUTHEAST FLOW IS SUSTAINING SIGNIFICANT WATER VAPOR INFLOW WITH PRECIPITABLE WATER AROUND 1.5 AND FORECASTED AFTERNOON MUCAPES FROM 500 TO 1000 J/KG OVER MOST OF THE REGION. INVERTED TROUGH WILL BE MOVING ACROSS THE AREA THIS AFTERNOON AND THIS EVENING GENERATING SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS AGAIN. FREEZING LEVELS ABOVE 12,00 FEET AGL INDICATE EFFICIENT WARM CLOUD RAIN PROCESSES WILL OCCUR WHILE STEERING FLOW UNDER 10 KT AND DEEP MOISTURE SUGGEST SLOW MOVING AND POSSIBLY EVEN BACK BUILDING CELLS WITH LITTLE OUTFLOW. THUS POTENTIAL FOR HEAVY RAINS AND ISOLATED AREAS OF FLOODING WILL PERSIST THROUGH AT LEAST TONIGHT. LARGER SCALE TRENDS THOUGH THE REMAINDER OF THE WEEK SHOULD INCLUDE THE RIDGE AXIS SHIFTING SOUTHWARD INTO THE CWA. THIS WILL RESULT IN SYNOPTIC SCALE SUBSIDENCE AND INFLOW OF WARMER DRIER MORE STABLE AIR ALOFT. LOW LEVEL EAST TO SOUTHEAST FLOW WILL SUSTAIN ENOUGH MOISTURE TRANSPORT TO PRODUCE A FEW STORMS EACH DAY BUT OVERALL PATTERN CHANGE MEANS A GRADUAL DECREASE IN THUNDERSTORM COVERAGE AFTER MONDAY. && .AVIATION... MOIST UNSTABLE AIR WILL FLOW INTO SOUTHERN NEW MEXICO AND WESTERN TEXAS TODAY AND MONDAY WHILE AN UPPER LEVEL DISTURBANCE MOVES INTO THE REGION FROM THE EAST. THIS PATTERN WILL PRODUCE SCATTERED AREAS OF MVFR AND A FEW AREAS OF IFR CEILINGS AND VISIBILITIES IN SHOWERS AND THUNDERSTORMS. VISIBILITIES WILL BE REDUCED TO UNDER A QUARTER MILE IN HEAVY RAINS OVER ISOLATED LOCATIONS. && .FIRE WEATHER... MOIST UNSTABLE AIR WILL FLOW INTO SOUTHERN NEW MEXICO AND WESTERN TEXAS TODAY AND MONDAY WHILE AN UPPER LEVEL DISTURBANCE MOVES INTO THE REGION FROM THE EAST. AS A RESULT THERE WILL BE GOOD CHANCES FOR THUNDERSTORMS WITH A FEW STORMS PRODUCING AT LEAST 2 INCHES OF RAIN WITH FLOODING. THE WIDESPREAD WETTING RAINS SHOULD KEEP THE FIRE DANGER LOW OVER MUCH OF THE REGION. HIGH PRESSURE ALOFT WILL CAUSE SOME DECREASE IN THUNDERSTORM COVERAGE TUESDAY THROUGH FRIDAY. MINIMUM AFTERNOON RELATIVE HUMIDITIES WILL AROUND 30 TO 40 PERCENT TODAY AND MONDAY AND FROM 20 TO 30 PERCENT TUESDAY THROUGH FRIDAY. AFTERNOON WINDS SHOULD HAVE SPEEDS AROUND 10 TO 20 MPH WITH STRONGER GUSTS NEAR THUNDERSTORMS. && .PRELIMINARY POINT TEMPS/POPS...
