ONLY EXPECT LIGHT SNOW SHOWERS MAINLY MOUNTAINS OF NORTHEASTERN NV
ON MONDAY. COLD AIR ADVECTION OVER CWA MONDAY TO KEEP MAX TEMPERATURES
MAINLY IN THE 30S. SNOW SHOWERS SHOULD DIMINISH EARLY MONDAY AFTERNOON
AS HIGH PRESSURE BUILDS ALONG THE WEST COAST BRINGING DRIER AND
COLDER AIR INTO THE AREA. WITH THE COLD AIRMASS...HAVE LOWERED
MIN TEMPERATURES FOR TUESDAY MORNING 5 TO 10 DEGREES FROM PREVIOUS
FORECAST. VALLEYS OF NORTHEASTERN NEVADA MAY GET SEE A SNOW FLURRY
OR TWO ON MONDAY...HOWEVER NOT EXPECTING ANY SNOW ACCUMULATIONS IN
THE VALLEYS. LATEST ARW MODEL RUNS INDICATE WIND GUSTS MONDAY ON
THE EASTERN AND SOUTHERN SLOPES OF HIGHER TERRAIN LOWER THAN
PREVIOUS MODELS...WITH EXPECTED GUST NOW ONLY TO REACH INTO THE
30-40 MPH RANGE. JET PUSHES OFF TO THE EAST MONDAY NIGHT INTO
TUESDAY AS HIGH PRESSURE BUILDS IN FROM THE WEST.

.LONG TERM...WEDNESDAY NIGHT THROUGH SUNDAY...LONG RANGE MODELS
CONTINUE TO SHOW A SIGNIFICANT CHANGE TO THE WEATHER PATTERN ACROSS
THE WRN UNITED STATES LATE NEXT WEEK...WITH A STRONG POLAR LOW
BRINGING MUCH COLDER TEMPS TO THE REGION ALONG WITH A CHC OF
WIDESPREAD SNOW. FOR EARLIER IN THE WEEK...ABOVE NORMAL TEMPS ARE
EXPECTED TO CONTINUE WEDNESDAY AND THURSDAY AS HIGH PRESSURE BEGINS
TO DRIFT WEST OVER THE ERN PACIFIC. OTHER THAN A WEAK WAVE PUSHING
ACROSS THE AREA ON THURSDAY...EXPECT PARTLY CLOUDY SKIES AND DRY
CONDITIONS. MAY SEE A SNOW SHOWER OR TWO ACROSS ERN NV AS THIS WEAK
UPPER LEVEL TROUGH QUICKLY DIGS SOUTH ACROSS THE AREA.
OTHERWISE...LOW TEMPS WILL REMAIN ON THE COLD SIDE AND GENERALLY IN
THE TEENS TO LOW 20S.

LATER IN THE WEEK...MODELS SHOW STRONG UPPER LEVEL RIDGE CONTINUING
TO DRIFT WEST INTO THE CNTRL PACIFIC AND THEN INTENSIFYING...WITH
THE RIDGE AXIS EXTENDING NORTH INTO ALASKA. THIS WILL ALLOW POLAR
SYSTEMS TO DIG SOUTH INTO THE WEST COAST AS THE JET STREAM BECOMES
MORE ACTIVE AND INTENSIFIES. LATE ON FRIDAY...ECMWF AND GFS SHOW THE
FIRST SYSTEM NEAR THE CANADA/U.S. BORDER PUSHING SOUTH INTO THE PAC
NORTHWEST...BRINGING WINDY CONDITIONS AND MUCH COLDER TEMPS. GFS IS
NOTICEABLY MUCH QUICKER COMPARED TO THE ECMWF...SHOWING THE STRONG

PUSHING INTO NRN NV AS EARLY AS FRIDAY NIGHT WHILE THE ECMWF SHOWS
SNOW PUSHING INTO NRN NV SATURDAY AFTERNOON. LOWERED POP A BIT
FRIDAY NIGHT AS WELL AS INCREASED SNOW LEVELS WITH WARMER AIR AHEAD
OF THE COLD FRONT. BOTH MODELS SHOW COLD FRONT PUSHING ACROSS CNTRL
NV BY EARLY SUNDAY AS 700MB TEMPS PLUMMET TO -16C ACROSS THE
NORTH...WHICH IS A BIT COLDER COMPARED TO PREVIOUS RUNS. BOTH MODELS
NOW IN AGREEMENT THROUGH THE WEEKEND SHOWING THE UPPER LEVEL LOW
REMAINING OVER THE WEST COAST WITH COLD AIR PUSHING AS FAR SOUTH AS
SRN CALIF AND AZ.  NOT GOING TO ESTIMATE PRECIP AMOUNTS QUITE YET
DUE TO DIFFERENCES IN STORM TRACK BETWEEN MODEL RUNS...BUT THE
POTENTIAL EXISTS FOR THE FIRST MODERATE SNOWFALL OF THE SEASON
ACROSS NRN AND CNTRL NV...WITH CNTRL NV SOUTH OF HIGHWAY 50 AND ERN
NV LOOKING LIKE THE BEST AREAS TO SEE ACCUMULATING SNOW. INCREASED
POP TO BETWEEN 40 TO 55 PCT OVER THE AREA SATURDAY AND SUNDAY.
