NWS Elko, NV wrote its last area forecast discussion before the first event at Jul 25, 2:45 PM PST, 15 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ELKO NV 345 PM PDT SUN JUL 25 2010 .SYNOPSIS...THE DRY AIR MASS WILL SLOWLY SUCCUMB TO A MORE MOIST AIR MASS MOVING IN FROM THE SOUTH. THIS WILL BRING INCREASING CHANCES FOR THUNDERSTORMS TONIGHT. SOME STORMS MONDAY AFTERNOON AND TUESDAY AFTERNOON COULD BECOME STRONG WITH WIND GUSTS IN EXCESS OF 50 MPH AND SMALL HAIL. MOISTURE WILL TRY TO LINGER IN THE EAST...BUT IS ANTICIPATED TO SLOWLY DRY OUT IN THE WEST. TEMPERATURES ARE EXPECTED TO BE AT OR JUST ABOVE NORMAL FOR THIS TIME OF YEAR. && .SHORT TERM...TONIGHT THROUGH TUESDAY. CONSIDERABLE CLOUDINESS SEEN ACROSS THE FORECAST AREA TODAY BUT LITTLE IN THE WAY OF THUNDERSTORM DEVELOPMENT. RADAR THIS AFTERNOON SHOWS A FEW CELLS TREKKING NORTH ACROSS THE AREA WITH THE BEST ACTIVITY AT THIS TIME DEPICTED OVER NORTHERN NYE COUNTY MOVING NORTH. GENERAL PATTERN REMAINS SIMILAR WITH AN UPPER LEVEL RIDGE CIRCULATING EAST OF THE STATE OVER CENTRAL UTAH WHILE AN UPPER LOW IS SLOWLY MOVING EAST TOWARDS THE CA COAST. SOUTHERLY FLOW IS ALLOWING MOIST AIR TO MOVE NORTHWARD OVER THE STATE. MAJORITY OF THE ACTIVITY HAS BEEN ACROSS EXTREME WESTERN NEVADA THIS AFTERNOON. PV15 ANOMALY IS SEEN MOVING OVER THE NORTHWESTERN PART OF THE STATE THIS AFTERNOON AND EVENING WITH A STRONG 250MB JET OF 60 KNOTS BISECTING THE STATE FROM SOUTHWEST TO NORTHEAST. UPPER LEVEL LAPSE RATES ARE AROUND 7 TO 7.5 C/KM. THERE IS SOME MUCAPE PER THE GFS FOR THE OVERNIGHT AT ABOUT 100-150 J/KG. THEREFORE...ISOLATED THUNDERSTORM ACTIVITY IS POSSIBLE DURING THE OVERNIGHT AND HAVE KEPT POPS GOING THROUGH THIS TIME. ON MONDAY MOISTURE INCREASES SIGNIFICANTLY VERSUS TODAY AS PRECIPITABLE WATER VALUES INCREASE TO 0.70 TO 0.90 INCHES FROM WEST TO EAST. PV ANOMALY IS PROJECTED TO MOVE ACROSS THE NORTHWEST PART OF THE FORECAST AREA...OVER HUMBOLDT COUNTY TOMORROW. UPPER LEVEL JET WILL REMAIN FAIRLY STRONG AT 65+ KNOTS WHILE UPPER LEVEL LAPSE RATES CONTINUE TO REMAIN ABOVE 7.25 C/KM. TOMORROW'S CONVECTIVE ACTIVITY IS PROJECTED TO INCREASE OVER TODAY. THINKING IS THAT MOST IF NOT ALL THE STORMS WILL START OUT DRY AND THEREFORE HAVE EXPANDED AND EXTENDED COVERAGE OF THE RED FLAG WARNING THROUGH TOMORROW EVENING. PLEASE SEE PRODUCT RNORFWLKN FOR MORE DETAILS. ONE MORE CONCERN IS IN REGARDS TO THE SEVERE WEATHER THREAT. GFS SOLUTION SHOWS MODEST CAPE VALUES OF ABOUT 400-600 J/KG ACROSS THE NORTHERN PORTION OF THE FORECAST AREA...WITH 0-6 KM BULK SHEAR VALUES OF 40 TO 50 KNOTS FOR THE MONDAY AFTERNOON PERIOD. ISOLATED STRONG THUNDERSTORMS ARE DEFINITELY A POSSIBILITY DURING MONDAY AFTERNOON...WITH THE PRIMARY THREAT BEING STRONG WIND GUSTS WITH THE SECONDARY THREAT OF SMALL HAIL. GIVEN THE SPEED AT WHICH THESE STORMS ARE GOING TO BE MOVING...FLASH FLOODING APPEARS TO BE A LOW PROBABILITY. MUCAPE VALUES FOR MONDAY NIGHT CONTINUE TO SUGGEST POSSIBLE NOCTURNAL CONVECTIVE ACTIVITY FOR THE OVERNIGHT...SO HAVE KEPT POPS IN THE ISOLATED TO SCATTERED CATEGORY. STORMS DURING THIS TIME SHOULD BE ALL WET. TUESDAY AFTERNOON MAY BE ANOTHER ACTIVE DAY ACROSS NORTHERN NEVADA AS ONCE AGAIN AS SUFFICIENT ENERGY...INSTABILITY AND DECENT SHEAR BRING ANOTHER ROUND OF STRONG STORMS. .LONG TERM...TUESDAY NIGHT THROUGH NEXT SUNDAY. OVERALL PATTERN LOOKS SIMILAR TO PREVIOUS RUNS IN BOTH THE GFS AND ECMWF. THIS BASICALLY CONSISTS OF A QUASI-STATIONARY UPPER-LEVEL TROUGH OFF THE PACIFIC NORTHWEST COAST...AND AN UPPER-LEVEL RIDGE OF HIGH PRESSURE OVER THE SOUTHERN PLAINS. BETWEEN THE TWO SYSTEMS...WINDS ALOFT WILL HAVE A SOUTHERLY COMPONENT THROUGH THE PERIOD. HOWEVER...AS SHOWN IN PREVIOUS RUNS...THE TROUGH IS EXPECTED TO GRADUALLY RETREAT A BIT FURTHER NORTH...WITH THE RIDGE BUILDING FURTHER WEST. THIS SHOULD ALLOW SOUTHERLY WINDS ALOFT TO BECOME MORE SOUTHWESTERLY OR EVEN WEST-SOUTHWESTERLY...WHICH SHOULD START TO SCOUR OUT THE MONSOONAL MOISTURE WHICH WILL BE IN PLACE AT THE START OF THE PERIOD. BOTTOM LINE IS A SLOW DECLINE IN THUNDERSTORM ACTIVITY FROM WEST TO EAST AS WE PROGRESS THROUGH THE LONG TERM. TEMPERATURES WILL GENERALLY RUN A BIT ABOVE NORMAL...WITH HIGHS WARMING SLIGHTLY BUT LOWS DECLINING SLIGHTLY AS WE HEAD TOWARD THE END OF THE PERIOD AS MOISTURE CLEARS OUT AND THE RIDGE BUILDS. RCM && .AVIATION...VFR CONDITIONS EXPECTED THROUGH TOMORROW. MAIN CONCERN IS ISOLATED THUNDERSTORMS TONIGHT...BECOMING MORE WIDESPREAD TOMORROW. DO NOT EXPECT STORMS TO DIRECTLY AFFECT TERMINALS TONIGHT...BUT STORMS ARE POSSIBLE AT THE TERMINALS THEMSELVES AFTER APPROXIMATELY 17Z MONDAY. WINDS WILL GENERALLY REMAIN BELOW 20 KNOTS EXCEPT NEAR THUNDERSTORMS. CIGS WILL ALSO GENERALLY REMAIN WELL ABOVE 5K FEET...EXCEPT IN ANY HEAVY DOWNPOURS ASSOCIATED WITH STORMS. RCM && .FIRE WEATHER...ONLY ISOLATED DRY THUNDERSTORMS CAN BE SEEN ACROSS THE FORECAST AREA THIS AFTERNOON WITH THE MAJORITY OF ACTIVITY BEING GENERATED IN NORTHERN NYE COUNTY THIS AFTERNOON. HAVE EXTENDED AND EXPANDED THE RED FLAG WARNING TO INCLUDE ALL FIRE WEATHER ZONES THROUGH MONDAY AT 6 PM PDT. ACTIVITY THIS EVENING IS EXPECTED TO BE ISOLATED...BUT WILL QUICKLY BECOME MORE ACTIVE DURING THE LATE MORNING TO EARLY AFTERNOON HOURS. MOISTURE WILL INCREASE DURING THE MORNING HOURS AND STORMS WILL TRANSITION FROM DRY TO WET AS THE NORTHEASTWARD PROGRESSION OF MOISTURE CONTINUES. OTHER THAN LIGHTNING...THE OTHER MAIN THREAT WILL BE STRONG WIND GUSTS THAT COULD EXCEED 50 MPH. STORMS FOR MONDAY NIGHT AND TUESDAY WILL BE ALL WET AS THE MOIST AIR MASS REMAINS OVER THE AREA. BY WEDNESDAY DRIER AIR WILL TRY TO FILTER INTO THE FIRE DISTRICT...WITH BEST CHANCES FOR ACTIVITY MAINLY IN THE EASTERN HALF OF THE FORECAST AREA. UNSETTLED WEATHER EVENTUALLY DIMINISHES FROM WEST TO EAST BY THE WEEKEND. && .LKN WATCHES/WARNINGS/ADVISORIES... RED FLAG WARNING UNTIL 6 PM PDT MONDAY FOR HUMBOLDT COUNTY...
