AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE EL PASO TX/SANTA TERESA NM 211 PM MDT MON AUG 23 2010 .SYNOPSIS... AN UPPER LEVEL TROUGH WILL PASS JUST NORTH OF THE AREA THIS AFTERNOON AND TONIGHT...CAUSING SCATTERED THUNDERSTORMS TO DEVELOP THROUGH TONIGHT. A STRONG COLD FRONT WILL MOVE SOUTH THROUGH THE STATE TOMORROW WITH ADDITIONAL SCATTERED THUNDERSTORMS EXPECTED. SOME OF STORMS MAY BECOME SEVERE...CAPABLE OF LARGE HAIL AND WIND GUSTS IN EXCESS OF 60 MPH. MUCH COOLER TEMPERATURES WILL OCCUR AFTER THE FRONT MOVES THROUGH THE AREA...WHICH SHOULD PERSIST THROUGH THE END OF THE WEEK. A MORE ISOLATED PATTERN OF SHOWERS AND THUNDERSTORMS WILL OCCUR WEDNESDAY AND THURSDAY. AN INCREASE IN MOISTURE WILL IMPROVE CHANCES FOR RAIN FOR FRIDAY AND NEXT WEEKEND. && .DISCUSSION... SCATTERED STRONG THUNDERSTORMS DEVELOPED QUICKLY OVER THE HIGHER MOUNTAINS BY MID DAY. WHILE HIGH PRESSURE ALOFT REMAINS IN PLACE. A COMBINATION OF A MOIST UNSTABLE ATMOSPHERE AND A TROUGH PASSING NORTH OF THE AREA HAS SET UP CONDITIONS FAVORABLE FOR THUNDERSTORM DEVELOPMENT FOR THE REST OF THIS AFTERNOON AND TONIGHT. THESE STORMS ARE PRODUCING HEAVY RAINFALL AND HAIL. LOCALIZED FLOODING ALONG DRAINAGES...ARROYOS AND MOUNTAIN STREAMS IS POSSIBLE THROUGH TONIGHT. THE NEXT WEATHER FEATURE TO IMPACT THE AREA IS A STRONG COLD FRONT PUSHING SOUTH THROUGH THE STATE TOMORROW. MOST MODELS PROJECT THE FRONT TO BE IN THE FORECAST AREA BY MORNING WITH ALL AREAS EXPECTED TO AFFECTED BY MID AFTERNOON. THE FRONT WILL PROVIDE BOTH LIFT AND A FOCUS FOR STRONG THUNDERSTORM DEVELOPMENT FOR TOMORROW. SOME OF THE STORMS MAY APPROACH SEVERE CRITERIA...CAPABLE OF LARGE HAIL AND STRONG WIND GUSTS AS WELL AS HEAVY RAINFALL. COOLER AIR BEHIND THE FRONT WILL BRING MUCH COOLER TEMPERATURES TO THE REGION WITH AS MUCH AS 10 DEGREES COOLING POSSIBLE FROM THE PREVIOUS DAY. THE FRONT WILL HAVE COMPLETELY PUSHED THROUGH THE AREA BY WEDNESDAY MORNING. THAT MAY BE A STABILIZING INFLUENCE ON THE GENERAL WEATHER PATTERN FOR ALL BUT THE BOOTHEEL. THAT SAID WILL CONTINUE TO INCLUDE A MENTION OF ISOLATED THUNDERSTORMS FOR BOTH WEDNESDAY AND THURSDAY FOR NOW. TEMPERATURES WILL REMAIN COOLER WITH DAY TIME HIGHS SLIGHTLY BELOW NORMAL. ANOTHER SHIFT IN THE WEATHER PATTERN WILL OCCUR ON FRIDAY AS A THE HIGH ALOFT FINALLY SHIFTS TO THE EAST OVER THE MISSISSIPPI RIVER VALLEY IN RESPONSE TO A DEEP TROUGH ON THE WEST COAST. THE CHANGE IN PATTERN WILL RESULT IN SOUTHERLY TO SOUTHWEST FLOW OVER THE LOCAL AREA THAT WILL TAP SUB TROPICAL MOISTURE AND BRING IT INTO THE REGION. THIS WILL INCREASE CHANCES FOR RAIN SHOWERS FOR FRIDAY THROUGH THE WEEKEND AND INTO THE FIRST PART OF NEXT WEEK. DAY TIME TEMPERATURES WILL REMAIN NEAR OR SLIGHTLY BELOW NORMAL && .AVIATION...VALID 24/00Z-25/00Z... UPR LVL HI REMAINS CENTERED OVR S NEW MEXICO.
