NWS Elko, NV wrote its last area forecast discussion before the first event at Sep 21, 1:11 AM PST, 3 hours 49 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ELKO NV 211 AM PDT SUN SEP 21 2014 .SYNOPSIS...AN UPPER LEVEL LOW WILL BRING WIDESPREAD RAIN AND THUNDERSTORMS TO NEVADA TODAY. DRIER WEATHER WILL BEGIN RETURNING MONDAY AS THE LOW MOVES AWAY. AFTER A BIT OF COOLING TODAY...WARMER WEATHER WILL RETURN BY MID WEEK. && .SHORT TERM...TODAY THROUGH TUESDAY. UPPER LEVEL LOW IS THE MAIN STORY. AT PRESENT IT IS CENTERED IN CENTRAL CALIFORNIA. A WARM FRONT LIKE FEATURE EXTENDS EAST-NORTHEAST FROM IT AND IS FOCUSING STRATIFORM PRECIPITATION ACROSS CENTRAL NEVADA...SPREADING NORTHWARD SLOWLY. SOUTH OF THIS FEATURE THE AIR MASS IS MORE UNSTABLE WITH SHOWERS AND THUNDERSTORMS. AS WE HEAD THROUGH THE DAY THE WARM FRONT-LIKE FEATURE WILL MOVE NORTHWARD TOWARD THE IDAHO BORDER SPREADING RAIN WITH IT THIS MORNING. THIS FEATURE APPEARS TO WEAKEN THIS AFTERNOON BUT BY THEN MOST OF THE CWA WILL BE IN THE UNSTABLE AIR MASS SOUTH OF IT AS THE UPPER LEVEL LOW CENTER MOVES INTO NORTHWESTERN NEVADA. THIS SHOULD RESULT IN CONTINUED SHOWERS AND THUNDERSTORMS. STORM MOTIONS LOOK DECENT...AND WITH PLENTY OF FORCING AND A BIT OF SHEAR SOME SEVERE WEATHER IS POSSIBLE. ALSO SOME FLOODING ISSUES POSSIBLE BUT SEE THE HYDROLOGY SECTION BELOW FOR MORE DETAILS. AS THE LOW HEADS NORTHEAST INTO IDAHO THIS EVENING FORCING SHOULD QUICKLY WANE BOTH ON THE BROAD SCALE AND MESOSCALE AND MOISTURE LEVELS SHOULD FALL OFF...SO SHOWER/STORM COVERAGE WILL QUICKLY DIMINISH OVERNIGHT. SHORTWAVE RIDGE BUILDS INTO NEVADA ON MONDAY...BUT SOME LINGERING MOISTURE/FORCING/CYCLONIC CURVATURE WILL REMAIN OVER THE FAR NORTHEAST...SO HAVE SOME ISOLATED/SCATTERED SHOWERS/T-STORMS IN THAT AREA WHILE THE REST OF THE CWA SHOULD DRY OUT. THE RIDGE SHIFTS ONLY SLIGHTLY EAST ON TUESDAY WITH A BROAD SOUTHWESTERLY FLOW BRINGING EVER DRIER AIR INTO THE AREA WITH NO FORCING...SO TUESDAY SHOULD BE DRY AND MOSTLY SUNNY. TEMPERATURES TODAY WILL BE CONSIDERABLY COOLER THAN RECENT DAYS THANKS TO THE CLOUDS AND RAIN. THEY SHOULD REBOUND TO NEAR NORMAL ON MONDAY AND BOUNCE BACK ABOVE TUESDAY WITH THE RIDGE AND SOUTHWESTERLY FLOW ALOFT. RCM .LONG TERM...TUESDAY NIGHT THROUGH NEXT SUNDAY. MAJOR MODELS AGREE NICELY THURSDAY EVENING THEN DIFFERENCES APPEAR. BIG STORY FROM TUESDAY NIGHT THROUGH THURSDAY MORNING IS DRY SOUTHWEST FLOW ALOFT. AS THIS TROF RESPONSIBLE FOR THIS DIGS AND CLOSES OFF THE SOCAL COAST...IT PICKS UP FAIRLY SUBSTANTIAL EASTERN PAC SUB-TROPICAL MOISTURE...DRIVING UP PW'S INTO THE REMAINDER OF THE LONG TERM FORECAST PERIOD. STARTING THURSDAY AFTERNOON...THERE IS ENOUGH RH AND DYNAMICS AND INSTABILITY TO WARRANT SHOWERS OR THUNDERSTORMS IN EVERY PERIOD THROUGH NEXT SUNDAY. HOWEVER...THE BEST INSTABILITY WILL BE OVER THE SOUTHEAST HALF OF THE FORECAST AREA OR IN THE EASTERN 100 MILES OR SO OF THE STATE. FRONT MOVES THROUGH THE REGION ON THURSDAY WITH GUSTY WINDS AND SIGNIFICANT DROP IN TEMPERATURES. WILL FEEL MORE LIKE FALL NEXT WEEKEND FOR THE FIRST TIME THIS SEASON. && .AVIATION...WIDESPREAD AREA OF SHOWERS AND THUNDERSTORMS OVER MOST OF CENTRAL...EASTERN...AND NORTHERN NEVADA THROUGH AT LEAST 06Z MONDAY. PRECIP STARTS TO MOVE EAST AFTER THAT...BUT WILL STILL AFFECT KEKO AND KELY THROUGH 12Z MONDAY. GENERALLY...VFR CONDITIONS EXPECTED AT ALL SITES...BUT NOW AND THEN MAY DROP TO BLO 5SM IN MODERATE TO HEAVIER SHOWERS. ALSO...THIS SYSTEM HAS A HISTORY OF PRODUCING WIND GUSTS TO BETWEEN 30 AND 40 KNOTS...EVEN WITHOUT THUNDER...SOME REDUCING VISIBILITY IN BLDU. && .FIRE WEATHER...NO CONCERNS TODAY WITH WIDESPREAD RAIN AND WET THUNDERSTORMS. GUSTY WINDS MAY BECOME AN ISSUE BY THE MIDDLE OF THE WEEK AS A PACIFIC FRONT APPROACHES. RCM && .HYDROLOGY...UPPER LEVEL LOW WITH NICE TROPICAL MOISTURE SOURCE WILL MOVE ACROSS THE REGION TODAY. ALREADY A POTENT BAND OF MODERATE TO HEAVY RAIN ACROSS CENTRAL NEVADA AT THIS HOUR WITH A PSEUDO WARM FRONT...WITH DECENT FGEN IN THIS AREA. THIS FGEN BAND SHOULD MOVE NORTH ACROSS THE REST OF THE CWA THIS MORNING WITH THE CONVECTIVE UNSTABLE AIR MASS SOUTH OF IT ADVECTING ACROSS MOST OF THE REGION. THUNDERSTORMS THIS AFTERNOON WILL BE VERY COMMON...ESPECIALLY WITH PW'S LOCALLY OVER 1 INCH...BUT STORM MOTION SHOULD BE DECENT. HOWEVER...ANY TRAINING CAN CAUSE FLOODING ISSUES SO HAVE LEFT FLASH FLOOD WATCH UNCHANGED. ALREADY AT THIS HOUR MESONET STATIONS IN CENTRAL NEVADA HAVE RECORDED NEARLY AN INCH OF RAIN IN SOME PLACES WITH RADAR ESTIMATES OF OVER AN INCH...SO ADDITIONAL RAIN WILL ONLY CAUSE PROBLEMS IN THESE AREAS. THE FLOOD THREAT WILL QUICKLY DWINDLE THIS EVENING AS THE LOW MOVES NORTHEAST INTO IDAHO AND MOISTURE LEVELS DROP ON WESTERLY WINDS BEHIND IT. RCM && .LKN WATCHES/WARNINGS/ADVISORIES...
