AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
330 AM PDT TUE JUN 28 2011

.SHORT TERM...
A VERY LATE SEASON STORM SYSTEM IS APPROACHING THE WEST COAST THIS
MORNING WITH RAIN ALREADY SPREADING INTO NRN CA AND SRN OR. AHEAD OF
THIS SYSTEM...GUSTY SOUTHWEST WINDS WILL DEVELOP ACROSS THE SIERRA
AND WRN NV AS A 95-100 KT JET MOVES OVER AND THE THERMAL/PRESSURE
GRADIENT TIGHTENS. NAM12 IS SHOWING A 20C 850 MB THERMAL GRADIENT
AND 11 MB SURFACE PRESSURE GRADIENT THIS AFTERNOON BETWEEN THE
WESTERN FOOTHILLS OF THE SIERRA AND CNTRL NV...IMPRESSIVE FOR THIS
TIME OF YEAR. THIS WILL BRING WIDESPREAD GUSTY WINDS TO 40 MPH TO
MUCH OF THE AREA...LOCALLY UP TO 50 MPH IN WIND PRONE AREAS ALONG
THE HWY 395 CORRIDOR...AND UP TO 70 MPH ON THE SIERRA RIDGES. WINDS
WILL PEAK DURING THE AFTERNOON...THE TAPER OFF OVERNIGHT AS THE FLOW
ALOFT WEAKENS AND GRADIENTS RELAX. SEE FIRE WEATHER SECTION FOR
DETAILS REGARDING THE GUSTY WINDS AND LOW HUMIDITY.

MAIN FRONTAL BAND WILL SLOW AS IT APPROACHES WRN LASSEN AND PLUMAS
COUNTIES MID DAY...SO TRIMMED BACK AFTERNOON POPS FOR THE TAHOE
BASIN AND ADJACENT AREAS TO ACCOUNT FOR THE DELAY. THE GFS AND NAM
ARE BOTH INDICATING SURFACE BASED AND ELEVATED INSTABILITY OVER NRN
WASHOE AND PERSHING COUNTIES WELL AHEAD OF THE MAIN FRONTAL BAND
UNDER INCREASINGLY DIFFLUENT FLOW ALOFT. WITH THE JET NOSING INTO
THE REGION DURING THE AFTERNOON...THERE SHOULD BE ENOUGH FORCING TO
KICK OFF ISOLATED THUNDERSTORMS. THE STORMS WILL BE MOVING QUITE
FAST...SO ADDED DRY THUNDER TO NRN WASHOE...PERSHING...AND CHURCHILL
COUNTIES. INSTABILITY WEAKENS BUT PERSISTS OVERNIGHT...SO MAINTAINED
ISOLATED THUNDERSTORMS THROUGH THE OVERNIGHT HOURS.

MAIN FRONTAL BAND WILL SPREAD INTO THE SIERRA AND WRN NV LATE
TONIGHT THROUGH WEDNESDAY MORNING. NO QPF CHANGES WITH EXPECTED
AMOUNTS NEAR AN INCH IN WRN LASSEN/PLUMAS COUNTIES...0.50-0.75
INCHES THE TAHOE BASIN...AND 0.10-0.35 INCHES ACROSS THE WESTERN
GREAT BASIN AND RANGE. MODELS STILL DISAGREE REGARDING AMOUNTS OVER
THE SIERRA IN MONO COUNTY. THE NAM SHOWS AS MUCH AS AN INCH OR MORE
WEST OF THE CREST WHILE THE GFS SHOWS NOT MUCH OF ANYTHING...AND THE
ECMWF IS SOMEWHERE IN THE MIDDLE. CURRENT FORECAST INDICATES AROUND
0.10-0.20 NEAR MAMMOTH TO 0.50 ON THE CREST ABOVE MONO VILLAGE. SEE
HYDROLOGY SECTION FOR MORE DETAILS. SNOW LEVELS WILL EVENTUALLY DROP
TO AROUND 8500 FEET EARLY WEDNESDAY MORNING...WITH UP TO 3 INCHES OF
NEW SNOW POSSIBLE ON THE HIGHER PEAKS.

UPPER LOW WILL SLOWLY MOVE THROUGH WEDNESDAY WITH SHOWERS DECREASING
IN COVERAGE FROM WEST TO EAST DURING THE DAY. INSTABILITY INCREASES
DRAMATICALLY ACROSS PERSHING AND CHURCHILL COUNTIES BY WEDNESDAY
AFTERNOON UNDER THE LEADING EDGE OF THE COLD POOL ALOFT...SO ADDED
SCATTERED THUNDERSTORMS TO THE FORECAST FOR AREAS EAST OF HWY 95.
HIGH TEMPERATURES WEDNESDAY WILL BE WELL BELOW AVERAGE. TEMPERATURES
MAY STRUGGLE TO REACH 70 IN RENO AND WILL LIKELY NOT EVEN HIT 60 IN
THE TAHOE BASIN. HARD TO BELIEVE THE LONGEST DAY OF THE YEAR WAS
JUST LAST WEEK. UPPER LOW SCOOTS EAST THURSDAY FOR DECREASING CLOUDS
AND ABOUT 10-15 DEGREES OF WARMING. SCV

.LONG TERM...FRIDAY THROUGH TUESDAY...
MEDIUM RANGE MODELS ARE IN VERY GOOD AGREEMENT THIS FORECAST CYCLE.
NOT ATYPICAL FOR A BUILDING RIDGE. ALL OPERATIONAL MODELS AND MOST
GEFS ENSEMBLE MEMBERS AGREE THAT FLAT FLOW ALOFT IN THE WAKE OF
EXITING LOW EARLY FRIDAY WILL TRANSITION TO RIDGING ALOFT AS FOUR
CORNERS HIGH BEGINS TO TAKE SHAPE BY LATE SATURDAY.

MSTR SHOULD BEGIN TO RETURN AROUND THE PERIPHERY OF THE HIGH SUNDAY
WITH DEEPER MSTR BY MONDAY AND BEYOND THE FORECAST PERIOD INTO
TUESDAY. GFS PWAT PROGS BRING AMOUNTS CLOSE TO 0.75 INCHES INTO THE
SRN CWA BY MONDAY AND EVEN HIGHER BY TUESDAY. SO INCREASED TSTM
COVERAGE FOR MONDAY AND EXPANDED IT TO THE NORTH INTO LASSEN
CONVERGENCE ZONE. LIGHT WINDS IN THE MID LVLS SHOULD LIMIT STORM
MOTION AS WELL SO ADDED SHOWERS TO TSTMS FOR MONDAY. MLF
&&

.AVIATION...
ANOMALOUSLY COLD UPPER LOW WILL APPROACH THE REGION LATER TODAY.
AHEAD OF THIS LOW SOUTH TO SOUTHWEST WINDS WILL INCREASE BY EARLY
AFTERNOON WITH GUSTS IN THE SIERRA REACHING AROUND 30 KT AND EAST OF
THE SIERRA WINDS GUSTING AS HIGHS AS 35 KT. WIND DIRECTIONS OFF THE
SFC LIKELY TO BE CLOSE TO SFC DIRECTIONS SO NOT EXPECTING A GREAT
DEAL OF LLWS. CIGS BEGIN TO FALL ACROSS THE SIERRA BY LATE MORNING
BUT DO NOT DROP BELOW VFR UNTIL THE AFTERNOON AS SHOWERS BEGIN TO
MOVE INTO THE RGN. VSBYS FALL INTO THE EVENING AS RAIN RATES
INCREASE. SOME SNOW POSSIBLE AT THE HIGHEST ELEVATIONS AS WELL WITH
POCKETS OF IFR CONDITIONS. EAST OF THE SIERRA PCPN WILL BE DELAYED
UNTIL LATER IN THE EVENING. ISOLATED TSTMS POSSIBLE ACROSS THE BASIN
AND RANGE THIS AFTERNOON PROVIDING A LIGHTNING THREAT AND GUSTY
WINDS AT THE SFC.

SHOWERS SPREAD OVER THE ENTIRE RGN TONIGHT AND LINGER INTO
WEDNESDAY. CIGS SHOULD DROP TO MVFR IN THE SIERRA AND NORTH OF TAHOE
WHILE REMAINING VFR EAST OF THE SIERRA EXCEPT IN THE HEAVIEST
SHOWERS WEDNESDAY MORNING. WINDS DECREASE FOR WEDNESDAY AS WELL.
LATE WEDNESDAY SHOWERS WILL END AND CIGS/VSBYS WILL IMPROVE. MLF

.FIRE WEATHER...
STRONG LOW PRESSURE FOR LATE JUNE WILL APPROACH THE REGION TODAY
WITH GUSTY WINDS EXPECTED AREA WIDE. THE STRONGEST WINDS WILL BE
NEAR AND SOUTH OF I-80 WITH GUSTS TO 45 MPH EXPECTED WHILE GUSTS
NORTH OF I-80 WILL BE 35-40 MPH. RED FLAG WARNINGS REMAIN IN AFFECT
FOR NV 450-453-459 AND CA 273 BELOW 7000 FEET. AREAS ABOVE 7000 FEET
STILL RATHER MOIST WITH SNOW COVER REMAINING IN MANY AREAS.

HUMIDITY ALSO LOOKS TO DROP TO 10-15% IN THE WARNING AREA FOR AT
LEAST A BRIEF PERIOD OF TIME. STILL...SINCE THIS SYSTEM HAS ABUNDANT
MOISTURE...HUMIDITY WILL LIKELY SLOWLY RISE DURING THE AFTERNOON
ALONG THE 395 CORRIDOR. FURTHER EAST...HUMIDITY SHOULD REMAIN LOW
ALL DAY...SO BY FAR THE WORST FIRE WEATHER CONDITIONS WILL OCCUR
ALONG AND EAST OF HIGHWAY 95.

ISOLATED DRY T-STORMS MAY DEVELOP IN NRN ZONE 453 THIS AFTERNOON AS
THE UPPER LOW APPROACHES. BEST CHANCE FOR DRY T-STORMS WILL BE NORTH
OF A PYRAMID LAKE TO LOVELOCK LINE WHERE UPPER LEVEL FORCING AND
INSTABILITY WILL BE GREATEST. ANY STORMS THAT DEVELOP WILL MOVE
NORTH AT AROUND 30-35 MPH.

AS THE LOW MOVES IN OVERNIGHT INTO WEDNESDAY...EXPECT WIDESPREAD
SHOWERS WITH MANY AREAS NEAR AND NORTH OF HWY 50 SEEING WETTING
RAINS. SOUTH OF HWY 50...MORE SCATTERED WETTING RAINS AS MOISTURE
THINS A BIT WITH THE LOW DROPPING FURTHER SOUTH. ISOLATED TO WIDELY
SCATTERED THUNDERSTORMS ARE ALSO POSSIBLE WEDNESDAY...ESPECIALLY
EAST OF HWY 95...BUT THEY WILL BE WET WITH MUCH COOLER TEMPERATURES
AND HIGHER HUMIDITY EXPECTED. MORE TYPICAL HOT/DRY WEATHER RETURNING
LATE WEEK WITH POSSIBLE AFTERNOON ZEPHYR EACH DAY BY SAT.

.HYDROLOGY...

* MODERATE FLOODING CONTINUES IN MASON VALLEY...YERINGTON AND
WABUSKA AREAS. SEE THE LATEST FLOOD STATEMENT FOR THE WALKER
RIVER FOR ADDITIONAL DETAILS.

WARMER TEMPERATURES MONDAY PROVIDED ANOTHER DAY OF GOOD MELTING IN
THE SIERRA AND SOME INCREASE IN STREAM FLOWS. INCREASED HUMIDITY
OVERNIGHT HAS HELPED TO MAINTAIN THIS MELTING. THAT SHOULD CHANGE
OVER THE NEXT 36 HOURS THOUGH AS COLD UPPER LOW MOVES INTO THE RGN.
TEMPS SHOULD BE COOLER TODAY THAN YESTERDAY AND MUCH COOLER BY
WEDNESDAY SLOWING THE MELTING FROM THE TAHOE BASIN SOUTH.

BUT THE LOW BRINGS THE POSSIBILITY OF ANOMALOUSLY HIGH RAINFALL
TOTALS FOR LATE JUNE WITH SNOW LEVELS STARTING ABOVE 9500 FEET
BEFORE FALLING TO AROUND 8500 FEET BY WEDNESDAY MORNING. FORECAST
MODELS GENERALLY SHOW THE HIGHEST RAINFALL TOTALS NORTH OF THE TAHOE
BASIN WITH MAXIMUM RAINFALL AMOUNTS 0.50-1.00 INCH STRETCHING INTO
WESTERN LASSEN COUNTY. FARTHER SOUTH AMOUNTS COULD RANGE FROM
0.25-0.50 FOR THE CARSON/WALKER HEADWATERS IN ALPINE AND MONO
COUNTIES...AND POTENTIAL FOR 0.10-0.35 INCHES ACROSS WESTERN NEVADA.

MAIN CONCERN WITH THIS SYSTEM IS THE STRONG LIFT AND A PRECIPITABLE
WATER PLUME OVER 1.25 INCHES PUSHING INTO THE SIERRA THIS EVENING
AND OVERNIGHT. IF EVERYTHING COMES INTO LINE WITH THE SYSTEM...
PRECIPITATION AMOUNTS COULD BE HIGHER...AND MAY EXACERBATE FLOOD
IMPACTS IN SMALL CREEKS AND STREAMS FROM TAHOE SOUTH DUE THE CURRENT
HIGH FLOWS AND MOIST SOIL CONDITIONS. THE HEAVIER RAINS TO THE NORTH
SHOULD RESULT IN SMALL STREAM RESPONSES IN THE SUSAN RIVER
BASIN...BUT REMAINING SNOWPACK THERE IS VERY LIMITED.

AFTER THE LOW QUICKLY EXITS ON THURSDAY...HIGH PRESSURE WILL BUILD
ACROSS THE WEST WITH AFTERNOON HIGHS RISING TO NEAR 10 DEGREES ABOVE
NORMAL FOR THE JULY 4TH HOLIDAY WEEKEND AND AGAIN INCREASE RUN OFF
AND FLOWS INTO MANY AREA STREAMS AND RIVERS.

FOR THE WALKER RIVER SYSTEM CURRENT FLOWS WILL PERSIST DOWNSTREAM IN
TO THE YERINGTON/MASON VALLEY NORTHWARD INTO WABUSKA. PREVIOUSLY
SPOTTERS REPORTED WATER TO WITHIN A FEW INCHES OF BRIDGE BOTTOMS
CROSSING THE WALKER RIVER IN THE MASON VALLEY...WITH SIGNIFICANT
FLOODING OF AGRICULTURAL AREAS AND FLOOD WATERS NEARING THE LOWEST
STRUCTURES ALONG THE RIVER.

FOR SMALLER CREEKS AND STREAMS IN MONO COUNTY...THE SMALL CREEK AND
STREAM FLOOD WARNING WAS EXTENDED THROUGH THURSDAY. FLOODING WILL
CONTINUE DUE TO THE MELTING SNOWPACK AND THE POSSIBILITY OF RAINFALL
ON TOP OF THE RIPE HIGH ELEVATION SNOWPACK. PREVIOUSLY SEVERAL
REPORTS OF FLOODED CAMPGROUNDS AND BACK COUNTY ROADS WERE RECEIVED
AND THESE COULD INCREASE/EXPAND WITH THE ADDITION OF THE RAINFALL
LATE TONIGHT AND WEDNESDAY. THIS WEEK SHOULD SEE PEAK FLOWS OF THE
SEASON AS WELL ABOVE AVERAGE TEMPS RETURN BY FRIDAY AND INTO THE
WEEKEND. BRONG/MLF/EKL/SCV
