AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE EL PASO TX/SANTA TERESA NM 229 PM MDT MON JUN 22 2009 .SYNOPSIS... A STEADY SOUTHEAST FLOW WILL BRING INCREASED MOISTURE TO THE REGION. AS A RESULT...ISOLATED TO SCATTERED THUNDERSTORMS AND SHOWERS WILL OCCUR THIS AFTERNOON AND TONIGHT. MOISTURE WILL REMAIN OVER THE AREA FOR MUCH OF THE WEEK. THERE WILL BE AT LEAST A SLIGHT CHANCE OF AFTERNOON AND EVENING THUNDERSTORMS EACH DAY. BEST CHANCES FOR RAIN WILL IN THE MOUNTAINS. HIGH PRESSURE ALOFT WILL HELP KEEP TEMPERATURES ABOVE NORMAL THROUGH NEXT WEEKEND. && .DISCUSSION... A COMBINATION OF HIGH PRESSURE CENTERED OVER TEXAS AND LOW LEVEL SOUTHEASTERLY FLOW WILL COMBINE TO TRANSPORT MOISTURE INTO THE AREA. SHOWERS AND THUNDERSTORMS HAVE ALREADY BEGUN TO DEVELOP OVER AREAS EAST OF THE RIO GRANDE THIS AFTERNOON WITH THE STRONGER STORMS OVER THE SOUTHERN SACRAMENTO MOUNTAINS. STORMS SHOULD CONTINUE INTO THE EVENING WITH EACH ZONE GETTING AT LEAST ISOLATED STORMS. MOISTURE WILL CONTINUE TO FLOW INTO THE REGION FROM THE SOUTH AND EAST THIS WEEK. PRECIPITABLE WATER VALUES WILL RISE ABOVE AN INCH THIS AFTERNOON AND REMAIN NEAR TO ABOVE AND INCH THROUGH THE WEEK. THE FOCUS FOR THUNDERSTORM ACTIVITY FOR TOMORROW WILL MORE TO THE WEST AS BUILDING HIGH PRESSURE ALOFT PUSHES THE MOISTURE PLUME MORE TO THE WEST. SCATTERED SHOWERS AND THUNDERSTORMS WILL OCCUR ALONG THE CONTINENTAL DIVIDE AND WESTWARD TOMORROW AFTERNOON AND EVENING WITH ISOLATED STORMS EAST OF THE DIVIDE. HEAVIEST RAIN AMOUNTS WILL BE IN THE MOUNTAINS OF THE GILA WILDERNESS. WITH THE PRECIPITABLE WATER VALUES SO HIGH...RAIN EFFICIENCY WILL BE IMPROVED WITH SOME BRIEF LOCALIZED FLOODING POSSIBLE IN HEAVIER RAIN SHOWERS. HIGH PRESSURE ALOFT WILL BUILD OVER THE STATE WEDNESDAY THROUGH TO NEXT WEEKEND. THE DOME OF HIGH PRESSURE WILL SUPPRESS THUNDERSTORM ACTIVITY SOMEWHAT UNTIL DAY TIME HEATING CREATES ENOUGH INSTABILITY AND BUOYANCY TO OVERCOME THE CAP. THERE WILL BE AT LEAST A SLIGHT CHANCE OF SHOWERS AND THUNDERSTORMS EACH AFTERNOON AND EVENING FOR THE REMAINDER OF THE WEEK. BEST CHANCE OF MEASURABLE RAINFALL WILL CONTINUE TO BE THE MOUNTAINS...SOME OF IT LOCALLY HEAVY. A SHORT WAVE TROUGH...PASSING NORTH OF THE AREA ON FRIDAY...WILL DEFORM THE HIGH SOMEWHAT AND MAY ENHANCE THUNDERSTORM ACTIVITY IN THE LATE FRIDAY TIME-FRAME. ABUNDANT MOISTURE TRAPPED UNDER THE HIGH WILL CONTINUE THROUGH THE WEEKEND WITH AT LEAST A SLIGHT CHANCE OF THUNDERSTORMS EACH DAY. DAY TIME TEMPERATURES WILL WARM TO ABOVE NORMALS DURING THE WEEK...BUT ADDITIONAL MOISTURE MAY KEEP A LID ON POSSIBLE 100 DEGREE TEMPERATURES FOR THE LOWLANDS. && .AVIATION...VALID 23/0000Z-24/0000Z... WESTWARD MOVING HIGH PRESSURE ALOFT OVER THE SOUTHERN STATES WILL CONTINUE TO SHOVE ADDITIONAL SUB-TROPICAL MOISTURE OVER OUR AREA THIS EVENING. ISOLD -TSRA/WND VRBL WITH MVFR VSBYS IN RA PSBLE MAINLY LOWLAND TERMINALS THRU 23/03Z...AS OUTFLOW INTERACTIONS SHOULD DICTATE SECONDARY TS DEVELOPMENT OVER DESERT AREAS EARLY THIS EVENING. SCT TSRA/MVFR VSBYS IN RA...WITH ISOLD EMBEDDED IFR VSBYS IN STRONGER STORMS LIKELY AFT 23/17Z ESPECIALLY FOR GILA WILDERNESS...WHERE MAJORITY OF DEEPER MOISTURE CIRCULATING AROUND HIGH WILL LIKELY END UP. && .FIRE WEATHER... ...MIX OF WET AND DRY TYPE STORMS ALL AREAS...ESPECIALLY GILA WILDERNESS...SACRAMENTO AND CAPITAN MOUNTAINS EACH AFTERNOON AND EARLY EVENING FOR LOWLAND EXPANSES... ONGOING BATTLE BETWEEN UNSEASONABLY STRONG PACIFIC TROUGH...AND SEASONAL DEVELOPMENT OF SUB TROPICAL HIGH OVER THE SOUTHERN PLAINS APPEARS TO BE LOST BY TROUGH...AS HIGH CONTINUES IS WESTWARD MOVEMENT TOWARDS NEW MEXICO. ATTENDANT CIRCULATION AROUND HIGH HAS REINTRODUCED ADDITIONAL SUB-TROPICAL MOISTURE BACK INTO THE PICTURE OVERNIGHT FOR THE SOUTHERN LOWLANDS. STRONG SUMMER HEATING WILL WORK WITH THIS MOISTURE...AND ADDITIONAL LIFT FROM DISTURBANCES MOVING THROUGH THIS SOUTHEASTERLY MOIST FLOW FOR ISOLATED TO SCATTERED SHOWERS/STORMS AREA-WIDE THIS AFTERNOON AND EARLY THIS EVENING. SUCCESSIVE MODEL SOLUTIONS WAVER SOMEWHAT ON LOCATION OF WHERE FETCH CARRIES GREATEST MOISTURE DEPTH...HOWEVER SOME CONSENSUS MAINTAINS BULK OF MOISTURE JUST TO OUR WEST IN AZ MIDWEEK...SWINGING BACK OUR WAY TOWARDS WEEKS END. FREQUENT CLOUD TO GROUND LIGHTNING... LOCALLY HEAVY RAINFALL WITH RAPID RUNOFF AND SMALL HAIL ARE THE MAIN THREATS WITH THESE STORMS. && .PRELIMINARY POINT TEMPS/POPS...

BE CAUTIOUS NEAR DRY STREAM BEDS AND ARROYOS AS THESE COULD FILL RAPIDLY. THESE STORMS ALSO COULD PRODUCE BRIEF WIND GUSTS OF 45 TO 50 MPH...SMALL HAIL...OCCASIONAL CLOUD TO GROUND LIGHTNING AND BRIEF REDUCTION OF VISIBILITY IN THE DESERT LOWLANDS IN PATCHY BLOWING DUST. ALWAYS REMEMBER...IF YOU SEE WATER PONDING OR FLOWING ACROSS ROADWAYS...TURN AROUND...DONT DROWN. NOVLAN
