TURNER

.PREV DISCUSSION... /ISSUED AT 331 PM /

SYNOPSIS...A MOIST PACIFIC STORM SYSTEM WILL CONTINUE TO BRING
WIDESPREAD RAIN AND SNOW TO THE SILVER STATE THROUGH SATURDAY
MORNING. AFTER A BRIEF BREAK IN PRECIPITATION SATURDAY
NIGHT...SNOW SHOWERS WILL RETURN TO THE REGION ON SUNDAY. A RETURN
TO SPRING IS EXPECTED NEXT WEEK...WITH DRY AND WARM CONDITIONS
EXPECTED.

SHORT TERM...FRIDAY NIGHT THROUGH MONDAY. SOME NICE RAINFALL HAS
FALLEN ACROSS PORTIONS OF THE CWA THUS FAR TODAY...WITH THE
HIGHEST READINGS APPROACHING .7" SO FAR. SNOW LEVELS HAVE
REMAINED ABOVE 6500FT SO FAR TODAY...BUT COLDER AIR ALOFT IS
CURRENTLY WORKING INTO THE REGION...AS 700MB AND SURFACE FLOW HAS
COME AROUND TO THE W/NW. COLDER AIR AND DYNAMIC COOLING DUE TO A
POTENT 500MB TROUGH WILL CONTINUE TO LOWER SNOW LEVELS THIS
EVENING ACROSS THE REGION. HAVE DECIDED TO KEEP HEADLINES AS
IS...BUT WAS A LITTLE CONCERNED ABOUT SNOWFALL ACROSS THE TONOPAH
AREA TONIGHT AS TEMPERATURES LOOK COLD ENOUGH. DO THINK THEY COULD
GET SOME SNOW ACROSS NORTHERN NYE COUNTY...BUT METRO ROAD MODEL
SHOULD THAT ROAD TEMPS WILL STAY ABOVE FREEZING...THUS DON'T THINK
THERE WILL BE MUCH IN THE WAY OF IMPACTS. THE WARNINGS STILL LOOK
GOOD...AS TEMPS WILL BE COLD ENOUGH TONIGHT FOR SNOW...HOW BIG THE
IMPACTS WILL BE IS STILL THE CONCERN...BUT METRO MODEL HAS ALL THE
PASSES ON U.S. HIGHWAY 50 GOING BELOW FREEZING TONIGHT.
ALSO...SNOW ACCUMULATED ON I-80 TODAY ACROSS THE SIERRA...SO NO
REASON WHY THAT WON'T HAPPEN ACROSS THE HIGHER PASSES DURING THE
OVERNIGHT HOURS WITH NO SOLAR INSULATION. HEAVIEST SNOW WILL OCCUR
FROM AUSTIN TO EUREKA TONIGHT...WITH WHITE PINE COUNTY NOT GETTING
IN ON THE ACTION UNTIL AFTER MIDNIGHT...AS 700MB NW FLOW TAKES A
LITTLE LONGER TO GET THERE. FURTHER NORTH AROUND THE RUBY MOUNTAIN
COMMUNITIES THE FORECAST REMAINS A LITTLE MORE CHALLENGING. THINGS
ARE GOING WELL AT THIS MOMENT...BUT HOW MUCH PRECIP WE GET AFTER
SUNSET IS THE DIFFICULT QUESTION AND SNOWFALL ACCUMULATIONS. RIGHT
NOW IT LOOKS LIKE UP-SLOPE COMPONENT FLOW SHOULD ALLOW SOME PARTS
OF SPRING CREEK/LAMOILLE/JIGGS/LEE...TO RECEIVE SOME GOOD
ACCUMULATING SNOW TONIGHT.

STORM PULLS AWAY SATURDAY MORNING...WITH SNOW ENDING AT ELY LAST.
BREAK IN THE ACTION IS EXPECTED ON SATURDAY NIGHT...ALLOWING A
HARD FREEZE ACROSS ALL LOCATIONS EXCEPT WENDOVER. SUNDAY LOOKS TO
BE A CONVECTIVE SNOW SHOWER DAY...WITH SOME GOOD GRAUPEL SNOW
SQUALLS POSSIBLE AS THE NEW SNOW SQUALL INDEX IS SHOWING SOME HIGH
VALUES. UNSETTLE WEATHER ENDS BY SUNDAY NIGHT...WITH COOL
NORTHWEST FLOW AND JUST SOME FAIR WEATHER CUMULUS CLOUDS ON
MONDAY.

LONG TERM...MONDAY NIGHT THROUGH FRIDAY. THE PERIOD BEGINS WITH
STRONG UPPER RIDGE BUILDING INTO THE REGION FOR DRY AND WARMER WEATHER.
THE RIDGE WILL REACH ITS PEAK STRENGTH WEDNESDAY AND THURSDAY THEN
BEGIN TO FLATTEN ON FRIDAY. TEMPS WILL BEGIN THE PERIOD SLIGHTLY
BELOW NORMAL WITH HIGHS IN THE MID 50S TO THE MID 60S BUT WILL END
THE PERIOD MUCH ABOVE NORMAL WITH HIGHS GENERALLY IN THE UPPER 60S
TO THE MID 70S.

AVIATION...STORM SYSTEM WILL BRING WIDESPREAD SHOWERS THROUGH
SATURDAY MORNING WITH AREAS OF MVFR CONDITIONS. RAIN IS EXPECTED TO
TURN OVER TO SNOW AT KTPH AROUND 04Z, AT KELY AROUND 10Z, AND KEKO
AROUND 12Z BRINGING IFR CONDITIONS.
