AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
234 AM PDT WED OCT 1 2014

.SYNOPSIS...

DRY CONDITIONS WILL PREVAIL THROUGH THE UPCOMING WEEK AS HIGH
PRESSURES BUILDS OVER CALIFORNIA AND WESTERN NEVADA. TEMPERATURES
START COOLER THAN SEASONAL AVERAGES TODAY AND TONIGHT BEFORE
WARMING ABOVE AVERAGE BY FRIDAY. OTHER THAN SOME SLIGHTLY BREEZY
CONDITIONS AT HIGHER ELEVATIONS, WINDS WILL GENERALLY BE LIGHT OUT
OF THE EAST.

&&

.SHORT TERM...

NO MAJOR CHANGES NECESSARY AS A RELATIVELY BENIGN PERIOD OF
WEATHER BEGINS TODAY AS HIGH PRESSURE BUILDS OVER THE SOUTHWESTERN
UNITED STATES. OUTSIDE OF OVERNIGHT LOWS TONIGHT INTO THURSDAY
MORNING APPROACHING FREEZING, THERE IS LITTLE TO DISCUSS.

TEMPERATURES WILL APPROACH FREEZING FOR MUCH OF THE FORECAST AREA
TONIGHT. HOWEVER, THE COLDEST TEMPERATURES REMAIN IN THE TYPICALLY
COLDER SIERRA VALLEYS AND EAST OF HIGHWAY 95 WHERE TEMPERATURES
WILL APPROACH 28 DEGREES. COLDEST SIERRA LOCATIONS WILL DROP INTO
THE LOW/MID 20S. THIS WILL BE A CONCERN FOR THOSE THAT HAVE
OUTDOOR PLANTS WITH SENSITIVITIES TO COLD TEMPERATURES. WESTERN
NEVADA LOCATIONS THAT WILL BE AFFECTED ARE: THE MASON AND SMITH
VALLEYS, AREAS AROUND FALLON AND LOVELOCK, AND VALLEYS EAST OF
FALLON INCLUDING GRASS VALLEY. AREAS OUTSIDE OF URBAN HEAT ISLANDS
AROUND RENO AND CARSON CITY MAY ALSO BRIEFLY DROP TOWARDS 32F, BUT
THE DURATION OF THESE TEMPERATURES WILL BE VERY BRIEF.

OTHERWISE, TEMPERATURES WILL GENERALLY BE IN THE MID 30S THIS
MORNING WARMING EACH DAY AS RIDGING MOVES OVER WESTERN NEVADA.
HIGHS WILL START COOL TODAY IN THE MID/UPPER 60S FOR WESTERN
NEVADA AND AROUND 60 IN THE SIERRA CLIMBING TO THE UPPER 70S/LOW
80S AND LOW/MID 70S RESPECTIVELY BY FRIDAY. WINDS REMAIN OUT OF
THE EAST TODAY WITH FASTEST FLOW ALONG HIGHER TERRAIN OF THE
SIERRA AND TO THE WEST. GENERALLY, SIERRA LOCATIONS CAN EXPECT
WINDS IN THE 10 TO 15 MPH RANGE WITH SOME GUSTS UP TO 20 MPH.
LOCATIONS EAST OF THE SIERRA WILL BE LIGHTER OUT OF THE EAST.
WINDS BECOME LIGHT AND VARIABLE THROUGH THE END OF THE WEEK MAINLY
RESPONDING TO TERTIARY FLOW FOLLOWING DIURNAL PATTERNS ALONG
TERRAIN FEATURES AS THE PRESSURE GRADIENT WEAKENS. BOYD

.LONG TERM...SATURDAY THROUGH TUESDAY...

A HIGH PRESSURE RIDGE OVER CA/NV WILL BE THE DOMINANT WEATHER
FEATURE THROUGH SUNDAY. EXPECT ABOVE-AVERAGE AFTERNOON TEMPERATURES
WITH WRN NV VALLEYS IN THE MID 70S TO MID 80S AND SIERRA VALLEYS IN
THE MID 60S TO MID 70S. WITH LIGHT WINDS AND LITTLE OR NO CLOUD
COVER, TEMPERATURE INVERSIONS WILL DEVELOP EACH NIGHT. WHILE A
WIDESPREAD FREEZE IS NOT FORECAST AT THIS TIME, LOW TEMPERATURES IN
THE TYPICALLY COLDER VALLEYS WILL LIKELY BE NEAR OR BELOW FREEZING
EACH NIGHT.

FOR MON-TUE, MOST COMPUTER GUIDANCE ADVERTISES A WEAK LOW PRESSURE
SYSTEM LOCATED OVER CALIFORNIA. THIS FEATURE COULD BRING WESTERLY
BREEZES AND COOLER AIR ACROSS THE SIERRA AND INTO WESTERN NV BY
TUESDAY. HOWEVER, FORECAST CONFIDENCE IN THIS PATTERN CHANGE IS LOW
BECAUSE OF DIFFERING MODEL SOLUTIONS AND BECAUSE MODELS TEND TO
STRUGGLE WITH THE TIMING AND LOCATION OF WEAK UPPER LOWS. JCM

&&

.AVIATION...

A COLD FRONT PASSAGE LATE YESTERDAY BROUGHT A DRIER AIR MASS AND
NORTHEAST WINDS ACROSS THE EASTERN SIERRA AND WESTERN NV.  AS SUCH,
FOG WILL BE LIMITED THIS MORNING EVEN IN SIERRA VALLEYS, WITH
ONLY A 20 PERCENT CHANCE FOR FOG AT KTRK. OTHERWISE...VFR CONDITIONS
ARE EXPECTED TODAY WITH SURFACE WINDS AROUND 10 KTS THIS AFTERNOON
AND EARLY EVENING, BECOMING LIGHT OVERNIGHT. OTHER THAN THE CHANCE
FOR FOG IN SIERRA VALLEYS, EXPECT LIGHT WINDS AND VFR CONDITIONS
THROUGH THE REST OF THE WEEK. JCM

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
216 PM PDT TUE SEP 30 2014

.SYNOPSIS...

DRY CONDITIONS WILL PREVAIL THROUGH THE UPCOMING WEEK. A WEAK COLD
FRONT PASSING THROUGH NEVADA TONIGHT WILL BRING COOLER TEMPERATURES
TO THE REGION WITH NORTHEAST TO EAST FLOW ON WEDNESDAY. HIGH
PRESSURE WILL THEN REBUILD OVER THE WEST AND BRING A WARMING TREND
STARTING THURSDAY, WITH ABOVE NORMAL TEMPERATURES FROM FRIDAY
THROUGH EARLY NEXT WEEK.

&&

.SHORT TERM...

SHORTWAVE MOVING ACROSS THE PACIFIC NORTHWEST THIS AFTERNOON WILL
MOVE SOUTHEAST ACROSS THE ROCKIES AND EASTERN GREAT BASIN TONIGHT.
SHALLOW BACK DOOR COLD FRONT MOVING SOUTHWARD ACROSS NEVADA WILL
BRING MODERATE NORTH TO NORTHEAST WINDS TONIGHT. FLAT CUMULUS
THIS AFTERNOON SHOULD DIMINISH THIS EVENING, ALTHOUGH SOME POST-
FRONTAL AND UPSLOPE STRATOCUMULUS COULD DEVELOP OVERNIGHT AND
LINGER INTO THE MORNING NEAR THE SIERRA AND IN FAR WESTERN NV.
ISOLATED SPRINKLES OR SNOW FLURRIES ARE EVEN POSSIBLE NEAR THE
SIERRA SOUTH OF TAHOE AND INTO WESTERN MONO COUNTY FOR THE LATE
EVENING AND OVERNIGHT HOURS, BUT MEASURABLE PRECIP IS UNLIKELY.

ON WEDNESDAY, STRONGER INVERSION SETTING UP WITH LOW LEVEL EAST
FLOW WILL LIMIT TEMPERATURE RISES WITH HIGHS UNLIKELY TO REACH 70
DEGREES IN LOWER ELEVATIONS. HIGHS IN THE TAHOE BASIN WILL BE
CLOSE TO THE WESTERN NV VALLEYS DUE TO THIS INVERSION.

FOR WEDNESDAY NIGHT, CLEAR SKIES AND LIGHT WINDS IN A DRIER AIR
MASS WILL ALLOW FOR GOOD RADIATIONAL COOLING OVERNIGHT.
TEMPERATURES MAY DROP BELOW FREEZING IN TYPICALLY COOLER VALLEYS
OF WEST CENTRAL NEVADA, INCLUDING THE MASON AND SMITH VALLEYS,
LOVELOCK-FALLON VICINITY, AND EASTERN PORTIONS OF PERSHING AND
CHURCHILL COUNTIES. OUTLYING AREAS AROUND RENO AND CARSON CITY
COULD ALSO SEE TEMPS DROP INTO THE LOWER-MID 30S FOR AN HOUR OR
TWO. WHILE A WIDESPREAD HARD FREEZE IS NOT PROJECTED, ANYONE WITH
SENSITIVE VEGETATION IN GARDENS OR FARM LANDS SHOULD CONSIDER
TAKING ACTION TO PROTECT THEM FROM COLD TEMPERATURES WEDNESDAY
NIGHT.

FOR THURSDAY, THE WARMING TREND WILL BEGIN AS RIDGE OFF THE WEST
COAST EDGES EAST INTO CALIFORNIA. TEMPS ARE LIKELY TO INCREASE BY
NEARLY 10 DEGREES COMPARED TO WEDNESDAY, RESULTING IN HIGHS
MAINLY IN THE 70S FOR MOST LOWER ELEVATIONS AS WELL AS THE SIERRA
VALLEYS. MJD

.LONG TERM...FRIDAY THROUGH TUESDAY...

FEW CHANGES MADE TO THE EXTENDED FORECAST AS DRY CONDITIONS WILL
PREVAIL WITH LITTLE TO NO CLOUD COVER AND LIGHT WINDS. DAYTIME
TEMPERATURES WILL BE ABOVE NORMAL EACH DAY WITH COOL NIGHTS THAT
ARE TYPICAL FOR EARLY OCTOBER.

HIGH PRESSURE RIDGE IS LIKELY TO REMAIN IN PLACE ACROSS THE REGION
THROUGH AT LEAST THE WEEKEND. MAX TEMPS SHOULD PEAK THIS WEEKEND
WITH HIGHS MAINLY IN THE LOWER TO MID 80S FOR LOWER ELEVATIONS.

BY EARLY NEXT WEEK BOTH THE GFS AND ECMWF ARE DEVELOPING A WEAK
LOW PRESSURE OFF THE CALIFORNIA COAST. THIS SYSTEM IS TOO FAR
OFFSHORE TO HAVE MUCH IMPACT ON WEATHER OVER EASTERN CA-WESTERN
NV, OTHER THAN POSSIBLY A SLIGHT DROP IN TEMPS NEXT MONDAY AND
TUESDAY. MJD

&&

.AVIATION...

WITH A COLD FRONT PASSAGE BRINGING DRIER AIR MASS AND NORTHEAST
WINDS LATER TONIGHT, THE POTENTIAL FOR FOG IN VALLEYS NEAR THE
SIERRA INCLUDING KTRK WILL BE LOWER THAN LAST NIGHT. IF ANY FOG
DOES MANAGE TO DEVELOP DUE TO RESIDUAL MOISTURE FROM THE WEEKEND
RAIN EVENT, IT WILL BE MORE LOCALIZED AND SHALLOWER WITH QUICKER
DISSIPATION WED MORNING.

OTHERWISE, VFR CONDITIONS WILL PREVAIL FOR THE NEXT SEVERAL DAYS.
N-NE WINDS AROUND 10 KT TONIGHT BECOME EAST WEDNESDAY AFTN-EARLY
EVE ESPECIALLY FOR KRNO-KCXP, FOLLOWED BY LIGHT WINDS FOR THE
REMAINDER OF THE WEEK. MJD

WEDNESDAY. THEN TEMPERATURES WARM ABOVE SEASONAL AVERAGES THURSDAY
INTO THE WEEKEND AS HIGH PRESSURE STRENGTHENS.

&&

.SHORT TERM...

FAIRLY QUIET WEATHER CONTINUES AS A RIDGE OVER THE EASTERN PACIFIC
TRANSLATES EASTWARD. ANOTHER ROUND OF SIERRA VALLEY FOG WILL OCCUR
THIS MORNING AS SOIL MOISTURE REMAINS ELEVATED WHILE TEMPERATURES
COOL TO SATURATION. BY THIS AFTERNOON, A WEEK PERTURBATION WILL
DROP DOWN THE BACKSIDE OF THE HIGH INCREASING NORTHERLY WINDS
EAST OF A CEDARVILLE TO WALKER LAKE LINE. GUSTS WILL NOT BE
OVERLY STRONG ONLY REACHING THE UPPER TEENS TO LOW 20 MPH RANGE.
THIS WAVE WILL REINFORCE COOLER TEMPERATURES TONIGHT THROUGH
THURSDAY MORNING.

AS A RESULT OF CLEAR SKIES, LIGHT OVERNIGHT WINDS, AND COOL AIR
ADVECTION, WE WILL EXPERIENCE THE COOLEST TEMPERATURES SINCE THIS
PAST SPRING. OVERNIGHT LOWS WILL APPROACH FREEZING TONIGHT MAINLY
IN THE SIERRA VALLEYS, THEN MORE EXTENSIVELY WEDNESDAY NIGHT EAST
OF HIGHWAY 95. LOCATIONS AFFECTED INCLUDE THE MASON VALLEY, SMITH
VALLEY, FALLON AREA, LOVELOCK AREA, AND THE GRASS VALLEY. THOSE
WITH CROPS THAT ARE SUSCEPTIBLE TO FROST OR FREEZING CONDITIONS
MAY WISH TO COVER THEM. WHILE WE ARE CONFIDENT THAT SPOTS IN THESE
LOCATIONS WILL REACH FREEZING TEMPERATURES EARLY THURSDAY MORNING,
THE EXTENT OF THE AREA IMPACTED CONTINUES TO BE FAIRLY LIMITED.
THEREFORE, A FREEZE WATCH/WARNING IS NOT WARRANTED AT THIS TIME.
OTHERWISE, BENIGN CONDITIONS ENSUE WITH TEMPERATURES WARMING ABOVE
SEASONAL AVERAGES THURSDAY INTO THE WEEKEND.

.LONG TERM...FRIDAY THROUGH MONDAY...

VERY FEW CHANGES MADE TO THE CURRENT EXTENDED FORECAST. MEDIUM RANGE
MODELS AND MOST ENSEMBLE MEMBERS ARE IN GOOD AGREEMENT WITH HOLDING
A RIDGE OVER THE REGION THROUGH SUNDAY. THERE ARE SOME DIFFERENCES
IN THE EVOLUTION OF THE RIDGE ON MONDAY WITH THE OPERATIONAL GFS AND
A FEW GEFS ENSEMBLE MEMBERS SHOWING A FLATTENING OF THE RIDGE.
MEANWHILE THE ECMWF AND MOST GEFS ENSEMBLE HOLD ON TO THE RIDGE.
WITH DIFFERENCES IN THESE SOLUTIONS...HAVE OPTED TO KEEP THE RIDGE
OVER THE AREA. A DIFFERENT SOLUTION WOULD REALLY ONLY RESULT IN SOME
CHANGE TO THE HIGH TEMPS FOR MONDAY AND LITTLE ELSE.

HIGH TEMPS SHOULD CLIMB ABOVE AVERAGE THROUGH THE EXTENDED FORECAST
WITH UPPER 70S TO LOWER 80S IN THE WRN NV VALLEYS ALONG WITH UPPER
60S TO LOWER 70S FOR THE SIERRA VALLEYS. LOW TEMPS ARE LIKELY TO BE
AT OR SLIGHTLY ABOVE AVERAGE. GIVEN RISING HEIGHTS EARLY IN THE
PERIOD...MID SLOPES COULD BE WARMER THAN THE VALLEYS FOR MORNING
LOWS. INVERSIONS SETTLE INTO THE VALLEYS EACH MORNING.

SLOWLY BUILDS IN WITH TEMPERATURES REMAINING ON THE COOLER SIDE
UNDER NORTHEASTERLY FLOW THROUGH WEDNESDAY. THEN TEMPERATURES WARM
ABOVE SEASONAL AVERAGES FROM MID WEEK INTO THE WEEKEND AS HIGH
PRESSURE STRENGTHENS.

&&

.SHORT TERM...

AS ANOTHER WAVE TRANSITS THE BACKSIDE OF THE LOW TODAY, ISOLATED
TO SCATTERED RAIN SHOWERS WILL FORM ACROSS NORTHERN WASHOE
COUNTY BEFORE MOVING INTO PERSHING AND EASTERN CHURCHILL COUNTIES
THROUGH THE EARLY AFTERNOON. MORNING FOG CAN BE EXPECTED IN SIERRA
VALLEYS THAT REMAIN CLEAR OF CLOUDS; ESPECIALLY ALONG THE MARTIS
AND SIERRA VALLEYS. OTHERWISE, THERE COULD BE SOME AREAS OF PATCHY
FOG IN WESTERN NEVADA PRIMARILY AROUND AREAS THAT RECEIVED OVER AN
INCH OF RAIN FROM THE PAST COUPLE OF DAYS. CLOUD COVER OVER
SOUTHERN OREGON WILL MOVE INTO WESTERN NEVADA BY THE MORNING AND
MAY SPOIL THE FOG FORECAST FOR LOCATIONS EAST OF THE VIRGINIA
RANGE.

LOW PRESSURE FINALLY EXITS INTO NORTHEASTERN NEVADA BY THIS
AFTERNOON. UPPER FLOW REMAINS AMPLIFIED WITH A RIDGE SLOWLY
BUILDING OUT OF THE SOUTH ALONG THE PACIFIC COAST. THIS FLOW
PATTERN WILL KEEP THE SIERRA AND WESTERN NEVADA UNDER COOLER
NORTHEASTERLY TO EASTERLY FLOW THROUGH MID WEEK STUNTING DAILY
HIGHS. HIGH TEMPERATURES WILL REMAIN IN THE UPPER 60S TO LOW 70S
FOR WESTERN NEVADA WITH 60S IN THE SIERRA FOR TODAY AND TUESDAY.
THEN A WEAK, DRY SHORTWAVE DROPS OUT OF THE PACIFIC NORTHWEST
COOLING TEMPERATURES BACK INTO THE MID/UPPER 60S FOR WESTERN
NEVADA AND UPPER 50S TO LOW 60S IN THE SIERRA ON WEDNESDAY.

ADDITIONALLY, WE COULD SEE THE FIRST FREEZING TEMPERATURES FOR
SOME AREAS TUESDAY AND WEDNESDAY NIGHTS AS SKIES BECOME CLEAR.
GENERALLY, TEMPERATURES WILL BE IN THE MID/UPPER 30S BUT COLDER
VALLEYS WILL APPROACH FREEZING. COLDER LOCATIONS INCLUDE VALLEYS
IN LASSEN COUNTY MAINLY TUESDAY NIGHT AND SOME OUTLYING VALLEYS
AWAY FROM URBAN CENTERS IN WESTERN NEVADA OVER WEDNESDAY NIGHT.

.LONG TERM...THURSDAY THROUGH SUNDAY...

ONLY VERY MINIMAL CHANGES WERE MADE TO THE CURRENT EXTENDED FORECAST
THIS CYCLE. OPERATIONAL MODELS AND ENSEMBLES ALL KEEP A RIDGE OVER
THE AREA THROUGH EARLY SUNDAY. THERE IS A LITTLE DIFFERENCE IN THE
EXACT LOCATION OF THE RIDGE AXIS BY LATE SATURDAY AS THE GFS
RETROGRADES THE RIDGE A BIT TO THE WEST. THIS WOULD CAUSE SLIGHTLY
LOWER TEMPS FOR SUNDAY...BUT WITH MOST ENSEMBLE MEMBERS AND THE
ECMWF KEEPING THE RIDGE OVER THE AREA AS OPPOSED TO RETROGRADING
IT...WILL NOT JUMP ON THE GFS SOLUTION YET.

THERE ARE BIGGER DIFFERENCES IN THE MODELS BEYOND SUNDAY AS THE ECMWF
STARTS TO BREAK THE RIDGE DOWN WHILE THE GFS HOLDS IT IN PLACE. THE
GEFS ENSEMBLES ARE ALMOST EVENLY SPLIT IN THEIR SUPPORT FOR THESE
SOLUTIONS.

HIGH TEMPS SHOULD RISE ABOVE AVERAGE BY FRIDAY AND STAY THAT WAY
THROUGH SUNDAY WHILE LOWS ARE NEAR TO SLIGHTLY ABOVE AVERAGE EACH
DAY. 20

.AVIATION...

RECENT RAIN HAS LEFT ENOUGH LOW LVL MOISTURE FOR FOG TO DEVELOP IN
THE MARTIS VALLEY THIS MORNING. FOG IS ALSO LIKELY IN THE SIERRA
VALLEY AND TYPICAL LOCATIONS IN WESTERN LASSEN COUNTY. EARLIER...FOG
DEVELOPED AROUND TVL...BUT THIS HAS SINCE DISSIPATED.

WITH THE UPPER LOW PULLING TO THE EAST TODAY...A FEW LINGERING
SHOWERS ARE POSSIBLE THIS MORNING OVER THE CHURCHILL AND PERSHING
COUNTIES. OTHERWISE...DRY AIR WILL START TO WORK INTO THE AREA WITH
IMPROVING FLYING WEATHER.

IFR IN THE FOG PRONE AREAS THIS MORNING WILL GIVE WAY TO MAINLY VFR
CONDITIONS BY LATE MORNING/EARLY AFTERNOON. LIGHT WINDS ARE EXPECTED
TODAY AND TONIGHT. THERE COULD BE FOG AGAIN TONIGHT IN THE FAVORED

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE RENO NV
910 PM PDT SUN SEP 28 2014

.UPDATE...

UPDATE THIS EVENING TO TAPER OFF SHOWERS AND THUNDERSTORMS THIS
EVENING, WITH A FEW ISOLATED SHOWERS CONTINUING OVERNIGHT AS THE
SECOND JET SEGMENT DROPS INTO NORTHERN NEVADA. THERE WILL BE
PERIODS OF CLEAR SKIES AND CLOUDS OVERNIGHT IN WESTERN NEVADA, SO
WITH THE RECENT RAINFALL OVER THE LAST COUPLE DAYS WE ADDED IN A
MENTION OF PATCHY FOG OVERNIGHT AND MONDAY MORNING. NOT THINKING
THAT THE FOG WILL BE WIDESPREAD, BUT SOME LOCALIZED AREAS IN THE
COLDER VALLEYS MAY DEVELOP FOG IF THE SKIES REMAIN PARTLY CLOUDY
INSTEAD OF MOSTLY CLOUDY. HOON

&&

.PREVIOUS DISCUSSION... /ISSUED 230 PM PDT SUN SEP 28 2014/

SYNOPSIS...
RAIN AND HIGH ELEVATIONS SNOW WILL CONTINUE INTO THIS EVENING AS
LOW PRESSURE SLOWLY MOVES INTO UTAH TONIGHT AND MONDAY. THE REST
OF THE WEEK WILL FEATURE DRY CONDITIONS WITH A WARMING TREND AS
HIGH PRESSURE RETURNS TO THE WEST.

SHORT TERM...

SLOW MOVING LOW WITH A WAVE WRAPPING AROUND ITS NORTH SIDE
CONTINUES TO PRODUCE SHOWERS AND A FEW THUNDERSTORMS OVER THE
NORTHERN SIERRA AND WESTERN NEVADA. THE ACTIVITY WILL MOVE SOUTH
OF HIGHWAY 50 THIS EVENING, THEN DISSIPATE OVER MONO, SOUTHERN
LYON AND MINERAL COUNTIES BY MIDNIGHT. SNOW LEVELS ARE RUNNING
NEAR 8500 FEET AND SHOULD REMAIN STEADY THIS EVENING AS
TEMPERATURES ALOFT WARM WHILE THE LOW MOVES INTO UTAH. HOWEVER
SNOW LEVELS COULD TEMPORARILY FALL TO 7500-8000 FEET UNDER HEAVIER
CONVECTIVE SHOWERS AND THUNDERSTORMS. ADDITIONAL RAINFALL AMOUNTS
UP TO 0.50 INCH ARE POSSIBLE WITH WITH 1-3 INCHES OF SNOW ABOVE
8500 FEET. A SECOND AREA OF SHOWERS SHOULD CLIP NORTHERN WASHOE
AND NORTHERN PERSHING COUNTIES LATE TONIGHT AND MONDAY MORNING AS
A JET SEGMENT OVER OREGON AND SOUTHERN IDAHO WRAPS INTO THE
NORTHWEST SIDE OF THE LOW.

AS SKIES START TO CLEAR OVER THE NORTHERN SIERRA AND POSSIBLY
PORTIONS OF WESTERN NEVADA TONIGHT, THE MOIST SURFACE CONDITIONS
MAY ALLOW FOG TO DEVELOP. FOR NOW PUT FOG IN THE FORECAST ONLY FOR
THE NORTHERN SIERRA VALLEYS AND AROUND THE TAHOE BASIN WHERE
CONFIDENCE IS HIGHEST IN CLEARING SKIES. OVERNIGHT LOWS MAY ALSO
DIP TO NEAR FREEZING IN THE SIERRA VALLEYS. ACROSS WESTERN NEVADA
IF SKIES DO CLEAR LATE TONIGHT LOWS MAY DIP INTO THE MID TO UPPER
30S FOR THE OUTLYING VALLEYS.

FOR MONDAY THE LOW WILL BE OVER UTAH WITH A DRYING NORTHWEST FLOW.
AFTERNOON HIGHS WILL WARM BACK INTO THE UPPER 60S TO LOW 70S FOR
WESTERN NEVADA WITH 60S IN THE SIERRA. OVERNIGHT LOWS WILL REMAIN
ON THE CHILLY SIDE, SO THOSE WITH SENSITIVE PLANTS MAY WANT TO
BRING THEM INDOORS OR COVER THEM.

FOR TUESDAY A WAVE WILL PASS ACROSS SOUTHERN OREGON AND IDAHO
ALLOWING A COLD FRONT TO SKIM NORTHWEST NEVADA. RAIN IS UNLIKELY
AT THIS TIME, BUT A FEW VERY LIGHT SHOWERS OR VIRGA MAY OCCUR
NORTH AND EAST OF CEDARVILLE TO LOVELOCK. BRONG

LONG TERM...WEDNESDAY THROUGH SUNDAY...

RIDGE OFF THE WEST COAST IS PROJECTED TO BUILD INTO CALIFORNIA AND
NEVADA LATER IN THE WEEK, AND REMAIN IN PLACE THROUGH NEXT WEEKEND.
THIS RIDGE WILL KEEP DRY AND CLEAR CONDITIONS WITH GENERALLY LIGHT
WINDS OVER THE REGION, WITH A WARMING TREND LATER IN THE WEEK.

TEMPERATURES WILL START A FEW DEGREES COOLER THEN NORMAL ON
WEDNESDAY, AS EAST FLOW BEHIND A SHORTWAVE MOVING THROUGH THE
ROCKIES BRINGS A STRONGER INVERSION OVER EASTERN CA-WESTERN NV.
HIGHS AROUND 70 DEGREES ARE EXPECTED FOR MOST LOWER ELEVATIONS, WITH
60S FOR THE SIERRA VALLEYS.

THE WARMING TREND WILL BEGIN THURSDAY WITH HIGHS RETURNING TO THE
70S FOR MOST VALLEYS, THEN RISING INTO THE LOWER 80S FROM FRIDAY
THROUGH SUNDAY.

WHILE TYPICALLY COOL OCTOBER NIGHTS ARE EXPECTED THROUGH THE
UPCOMING WEEK, THURSDAY MORNING WILL LIKELY BE THE COOLEST WITH LOWS
DIPPING INTO THE MID TO UPPER 30S FOR SOME OF THE COOLER VALLEYS OF
WESTERN NV. MJD

AVIATION...
BANDS OF SHOWERS AND ISOLATED THUNDERSTORMS WILL CONTINUE THROUGH
THIS AFTERNOON WITH MOST ACTIVITY DECREASING THIS EVENING. MAINLY
VFR CONDITIONS ARE EXPECTED EXCEPT FOR OCNL MVFR OR BRIEF IFR
CIGS/VSBY IN HEAVIER SHOWERS.

WITH MOIST GROUND AND SOME CLEARING LATER TONIGHT, AREAS OF FOG ARE
PROBABLE ESPECIALLY FOR PORTIONS OF THE TAHOE BASIN AND VALLEYS OF
NORTHEAST CA. FOR THE MAIN TERMINALS, THIS THREAT IS MOST LIKELY TO
AFFECT KTRK/KTVL WITH LIFR CIGS AND/OR VSBY MAINLY FROM 08-16Z.
LOCAL FOG OR LOW STRATUS COULD ALSO OCCUR IN PORTIONS OF WESTERN NV,
PRODUCING SOME MOUNTAIN OBSCURATIONS THRU MONDAY MORNING.

FOR THE REMAINDER OF MONDAY, VFR CONDITIONS ARE EXPECTED TO PREVAIL
WITH WINDS BECOMING WEST, BUT GUSTS SHOULD REMAIN BELOW 20 KT. MJD
