AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE EL PASO TX/SANTA TERESA NM 356 AM MDT MON MAY 4 2015 .SYNOPSIS... AN UPPER LOW WILL MOVE TO ARIZONA THIS AFTERNOON AND ACROSS NORTHERN NEW MEXICO ON TUESDAY. THIS WILL ALLOW ISOLATED SHOWERS AND THUNDERSTORMS TO CONTINUE TODAY AND TONIGHT. THE LOW MOVING ACROSS NEW MEXICO TUESDAY WILL ALLOW MOISTURE TO DIMINISH...WITH JUST A SLIGHT CHANCE FOR THUNDERSTORMS OVER THE MOUNTAINS. TEMPERATURES WILL RUN AT TO SLIGHTLY ABOVE NORMAL. WEDNESDAY INTO THE WEEKEND A DRY SOUTHWEST FLOW ALOFT WILL DEVELOP AND KEEP THE AREA DRY. AFTERNOONS WILL BECOME BREEZY...BUT DESPITE THIS...TEMPERATURES WILL REMAIN NEAR NORMAL. && .DISCUSSION... UPPER LOW NOW JUST OFF THE SOUTHERN CALIFORNIA COAST. HAS NOT BEGUN TO ENTRAIN MUCH MOISTURE SO HARD TO SEE. DRY SLOW CONTINUES OVER THE AREA BUT SO DOES A 130 KT JET WITH WEAK DISTURBANCES. THIS SHOULD BE GOOD ENOUGH FOR ANOTHER ROUND OF SHOWERS/THUNDERSTORMS TODAY AND TONIGHT. WINDS LIKELY MAIN HAZARD AGAIN. LATEST HRRR SHOWS DCAPES OF UP TO 850 J/KG. DEW POINT DEPRESSIONS SLIGHTLY LESS THAN SUNDAY BUT STILL AROUND 50 DEGREES THIS AFTERNOON. WIND GUST POTENTIAL LOOKS TO BE 40-50 MPH WITH ANY STORMS/SHOWERS. LACK OF DEEP MOISTURE AND/OR HIGH DEW POINTS SHOULD PRECLUDE HEAVY RAINFALL...MAYBE .25 - .50 INCHES WITH THUNDERSTORMS. UPPER LOW TO WESTERN NEW MEXICO TUESDAY MID DAY AND THEN OVER THE COLORADO ROCKIES BY TUESDAY EVENING. THIS LOW PASSAGE AND WEAK PACIFIC SURFACE FRONT WILL HELP TO SCOUR OUT MOISTURE SOME. MODELS STILL SHOWING JUST ENOUGH RESIDUAL MOISTURE AND INSTABILITY TO KICK OFF A FEW THUNDERSTORMS OVER THE MOUNTAIN ZONES. OTHERWISE POPS OUT FOR THE REST OF THE FORECAST PERIOD...AS DRY SOUTHWEST FLOW ALOFT AHEAD OF A WEST COAST UPPER TROUGH DEVELOPS AND PERSISTS INTO THE WEEKEND. AFTERNOONS WILL BECOME BREEZY TO WINDY THURSDAY THROUGH SATURDAY. DESPITE THIS PATTERN HIGH TEMPS SHOULD REMAIN AT OR SLIGHTLY ABOVE NORMAL. && .AVIATION...VALID 04/12Z-05/12Z... VFR CONDITIONS SHOULD PERSIST AT ALL TAF SITES THRU THE PERIOD. WEAK DISTURBANCES WILL RESULT IN ANOTHER ROUND OF HIGH BASED SHOWER ACTIVITY DEVELOPING AFTER 20Z WITH 26015G25KT SCT-BKN080-100 PREVAILING. -TSRA SCT-BKN080CB POSSIBLE OVER HIGHER TERRAIN AND AT KTCS DURING THE AFTERNOON AND EARLY EVENING. && .FIRE WEATHER... A FEW WEAK DISTURBANCES ALOFT WILL MOVE PAST THE REGION TODAY AND TONIGHT AS AN UPPER LOW TRACKS EAST FROM THE COAST OF SOUTHERN CALIFORNIA. THIS WILL BRING ANOTHER ROUND OF MAINLY HIGH BASED SHOWER ACTIVITY TO THE FIRE ZONES. INITIALLY MOST OF THE SHOWERS WILL EVAPORATE BEFORE REACHING THE SURFACE WHICH WILL PRODUCE LOCALLY GUSTY WINDS. THE BEST CHANCE FOR ACTUAL WETTING PRECIP WILL BE OVER THE HIGHER TERRAIN OF THE NORTH AS WELL AS THE FAR EASTERN FIRE ZONES THIS AFTERNOON AND EVENING. MIN RH VALUES WILL RUN ABOUT 2O PERCENT FOR THE LOWLANDS AND 30 PERCENT FOR THE MOUNTAINS TODAY. AS DEEP WESTERLY FLOW DEVELOPS TUESDAY MIN RH VALUES WILL DROP ABOUT 5 PERCENT WITH AN ADDITIONAL 5 PERCENT DECLINE FOR THE REST OF THE WEEK AHEAD. AS ANOTHER STRONGER UPPER STORM APPROACHES LATE WEEK STRONGER AFTERNOON SURFACE WINDS WILL DEVELOP WHICH COULD LEAD TO SOME FIRE WEATHER CONCERNS FOR THE THURSDAY THRU SATURDAY PERIOD. && .PRELIMINARY POINT TEMPS/POPS...
