The episode as NWS EPZ wrote it up.

NWS El Paso, TX wrote its last area forecast discussion before the first event at May 4, 2:00 PM MST, 30 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE EL PASO TX/SANTA TERESA NM 300 PM MDT MON MAY 4 2015 .SYNOPSIS... PLENTY OF MOISTURE AND INSTABILITY ACROSS THE REGION THIS EVENING WILL KEEP THE THREAT OF THUNDERSTORMS ONGOING. FOR AREAS EAST OF THE RIO GRANDE A THREAT OF SEVERE THUNDERSTORMS IS IN PLACE WITH THE POTENTIAL FOR LARGE HAIL AND DAMAGING WINDS. THE REGION DRYS OUT TUESDAY WITH THE RETURN OF DEEP WESTERLY FLOW. ONLY A FEW LINGERING STORMS LOOK POSSIBLE OVER THE MOUNTAINS. FOR THE REST OF THE WEEK EXPECT NEAR SEASONAL AFTERNOON TEMPERATURES WITH MILD MORNINGS. AFTERNOONS WILL BE BREEZY AND CONDITIONS WILL BE DRY. && .DISCUSSION... INGREDIENTS HAVE COME TOGETHER OVER AREAS EAST OF THE RIO GRANDE FOR SEVERE THUNDERSTORMS. LOW LEVEL EASTERLY FLOW HAS BROUGHT AND KEPT SURFACE DEWPOINTS UP AND PROVIDED GOOD VEERING WIND SHEAR. THIS HAS MEANT PLENTY OF CAPE AND LOW LI'S. THE RESULTS HAVE BEEN SEVERAL SEVERE STORMS...OUR FIRST OF THE YEAR. RIGHT BEFORE THE STORMS INCREASED IN INTENSITY WE ISSUED OUR FIRST SEVERE THUNDERSTORM WATCH OF THE YEAR FOR OTERO AND HUDSPETH COUNTIES. THIS IS WHERE THE STRONGEST STORMS HAVE BEEN. WE EXPECT THIS TO CONTINUE INTO THE EARLY EVENING HOURS BEFORE DIMINISHING. TO THE WEST THERE WILL BE STORMS ALSO IN THE EVENING HOURS...BUT THEY SHOULD LACK THE STRENGTH THE EASTERN STORMS HAVE. TUESDAY THIS FIRST UPPER LOW-PRESSURE SYSTEM WILL HAVE LIFTED NORTHEAST AWAY FROM THE REGION AND DEEPER DRY AIR WILL FILTER IN ON DEEP SOUTHWESTERLY FLOW. THIS SHOULD SCOUR OUT MUCH OF THE MOISTURE AND LEAVE ONLY THE MOUNTAINS WITH ENOUGH MOISTURE FOR ANY STORMS. THE LOWLANDS SHOULD BE DRY FOR THE REST OF THE WEEK AND THROUGH THE WEEKEND STARTING TUESDAY. THE PATTERN FOR THE REST OF THE WEEK KEEPS OUR AREA SOUTH OF A LARGE PACIFIC STORM SYSTEM THAT WILL BE SLOWLY TRACKING EAST AND PASSING TO OUR NORTH FRI/SAT OVER THE FOUR CORNERS. THIS PLACES US IN A PERSISTENT DRY WEST/SW FLOW PATTERN. WITH THE SYSTEM PASSING NORTH WE WILL BE IN REGION OF THE PATTERN WITH THE STRONGER WINDS AS LEE SURFACE TROUGHING HANGS TO OUR EAST AND A TIGHT GRADIENT ALOFT MIXING DOWN STRONGER WIND EACH AFTERNOON. MONDAY INTO TUESDAY WE COME UNDER SHORTWAVE RIDGING ALOFT WHILE HIGH PRESSURE AT THE SURFACE SETTLES OVER THE SOUTHERN PLAINS. THIS HELPS TO CUT OUR WINDS ALOFT AND ALLOWS FOR A SOUTHEASTERLY PUSH FROM THE GULF. THE RESULT WILL LIKELY BE AN INCREASING MOISTURE INGEST WITH THE DRY LINE BACKING WEST INTO OUR EASTERN ZONES. THIS WILL BE OUR NEXT OPPORTUNITY FOR STORMS AND RAIN...BEGINNING TUESDAY OF NEXT WEEK. && .AVIATION...VALID 05/00Z-06/00Z... VFR CONDITIONS SHOULD PERSIST AT ALL TAF SITES THRU THE PERIOD WITH SOUTH-SOUTHWESTERLY WINDS BETWEEN 15-20 KTS WITH GUSTS 20-25KTS. -TSRA SCT-BKN080CB POSSIBLE ACROSS ENTIRE REGION UNTIL 12Z. OVER HIGHER TERRAIN AND AT KTCS -TSRA UNTIL END OF PRD. STRONG WIND GUSTS AND REDUCED VISIBILITY COULD EXIST NEAR STORMS. 77-PAZOS && .FIRE WEATHER... THIS AFTERNOON AND TONIGHT AS A LOW PRESSURE SYSTEM FROM SOCAL MOVES EAST THROUGH THE AREA A CHANCE OF WETTING RAIN WILL EXIST FOR ALL FIRE WEATHER ZONES. WEST OF THE RIO GRANDE MOST ACTIVITY WILL BE HIGH BASED SHOWERS THAT COULD PRODUCE ERRATIC AND GUSTY WINDS WITH LITTLE TO NO ACCUMULATION. ALL ZONES EAST OF THE RIO GRANDE WILL HAVE A BETTER CHANCE FOR ACCUMULATING WETTING RAINS. THESE STORMS COULD PROCUDE LOCALLY HEAVY RAINFALL...STRONG WINDS AND LIGHTNING. A CHANCE OF RAIN SHOWERS AND THUNDERSTORMS WILL CONTINUE IN THE NORTHERN ZONES THROUGH TUESDAY AFTERNOON. DRY AND WARM WEATHER WILL PREVAIL WEDNESDAY THROUGH THE WEEKEND WITH BREEZY TO WINDY AFTERNOONS. MIN RH VALUES TODAY WILL WILL BE IN THE 20S FOR THE LOWLANDS AND THE GILA WILDERNESS. THE SACRAMENTO MOUNTAINS WILL SEE MIN RH VALUES IN THE UPPER 30S TO 40S. MIN RH VALUES WILL STEADILY DECREASE OVER THE NEXT FEW DAYS AS DEEP WESTERLY FLOW DEVELOPS RESULTING IN POSSIBLE NEAR RED FLAG CONDITIONS ON FRIDAY. && 77-PAZOS && .PRELIMINARY POINT TEMPS/POPS...
