AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
752 AM PDT WED JUN 20 2012
.SHORT TERM...
HIGH PRESSURE WILL QUICKLY PASS OVER THE SIERRA AND WESTERN NEVADA
TODAY AS AN UNSEASONABLY COLD LOW DEVELOPS IN THE NORTHEAST
PACIFIC. THIS STRONG LOW WILL ABSORB A CUTOFF LOW CURRENTLY NEAR
30 NORTH-135 WEST AND DRIVE IT INTO THE NORTHERN CALIFORNIA COAST
THURSDAY. BY FRIDAY THE STRONG LOW DROPS SOUTH OFF THE PACIFIC
NORTHWEST COAST, WITH WINDY AND COOLER CONDITIONS FOR THE END OF
THE WEEK.
FOR TODAY, TRANQUIL CONDITIONS WITH LIGHT WINDS, CLEAR SKIES AND
AFTERNOON HIGHS IN THE LOW TO MID 90S FOR WESTERN NEVADA WITH 80S
IN THE SIERRA.
MAIN CONCERN THURSDAY IS THE INCREASING WINDS DUE TO THE JET
PUSHING INTO THE NORTHERN SIERRA AND A SURFACE THERMAL GRADIENT
BETWEEN THE SIERRA AND CARSON-HUMBOLDT SINKS NEAR 20 DEGREES. WINDS
SHOULD BECOME GUSTY BY EARLY AFTERNOON IN THE SIERRA AND FAR
WESTERN NEVADA WITH GUSTS NEAR 35 MPH. THE GUSTY WINDS WILL PUSH
EAST OF HIGHWAY 395 BY LATE AFTERNOON AND CONTINUE INTO THE
EVENING HOURS. CHOPPY LAKE CONDITIONS ARE LIKELY FOR BOATERS ON
TAHOE, PYRAMID AND THE SMALLER LAKES AND RESERVOIRS OF THE EASTERN
SIERRA AND WESTERN NEVADA THURSDAY AFTERNOON.
ON FRIDAY, A NEW JET SEGMENT ROUNDS THE BASE OF THE LOW OFF THE
PACIFIC NORTHWEST COAST. AT THIS TIME WINDS MAY BE SLIGHTLY
LIGHTER FRIDAY DUE TO WEAKER SURFACE GRADIENTS AND THE WIND ENERGY
FROM THE JET STAY WEST OF THE SIERRA UNTIL FRIDAY NIGHT. PEAK
GUSTS SHOULD REMAIN NEAR AND BELOW 30 MPH. AFTERNOON HIGHS MAY
FALL OFF TO THE LOW TO MID 80S ACROSS WESTERN NEVADA WITH UPPER 60S
TO 70S FOR THE SIERRA.
AS THE JET MOVES ONSHORE FRIDAY NIGHT, IT PULLS A 1.00 INCH
PRECIPITABLE WATER PLUME INTO NORTHERN CALIFORNIA. A FEW SHOWERS
ARE POSSIBLE FROM WESTERN LASSEN TO THE SURPRISE VALLEY. BRONG
.LONG TERM...SATURDAY THROUGH TUESDAY...
FAIRLY DEEP UPPER LOW (-2 TO -3.5 STANDARD DEVIATIONS) OFF THE
CALIFORNIA COAST NEXT WEEKEND WILL EJECT INLAND IN A WEAKENED
FASHION EARLY NEXT WEEK. THE LOW OFF THE COAST WILL KEEP THERMAL
GRADIENTS/AFTERNOON-EVENING BREEZES GOING OVER EASTERN CALIFORNIA
AND WESTERN NEVADA FOR NEXT WEEKEND. TEMPERATURES ARE EXPECTED TO
REMAIN MODERATED INTO EARLY NEXT WEEK (TO WHAT DEGREE THERE IS
UNCERTAINTY ESPECIALLY BY MONDAY-TUESDAY) AS THE TROUGH BRINGS
COOLER AIR ALOFT INTO THE REGION.
AS FAR AS SPECIFIC DETAILS OF INTEREST, MODELS BRING IN SIGNIFICANT
700 MB MOISTURE SATURDAY FOR THE NORTHERN SIERRA, NORTHEAST
CALIFORNIA, AND FAR NORTHWEST NEVADA. HOWEVER, WITH THE JET FLOW
REMAINING OVERHEAD OR TO THE NORTH OF THESE AREAS MOISTURE DEPTH
SHOULD REMAIN FAIRLY SHALLOW WITH LIMITED INSTABILITY. THEREFORE, IT
LOOKS MORE LIKE THERE WILL BE CUMULUS WITH LIMITED VERTICAL EXTENT
RATHER THAN PRECIPITATION FOR NORTHEAST CALIFORNIA AND NORTHWEST
NEVADA ON SATURDAY.
THE OTHER SPECIFIC FEATURE OF POSSIBLE INTEREST WILL BE THE NATURE
OF THE EJECTING LOW MONDAY-MONDAY NIGHT. THE 00Z ECMWF BRINGS A 560
DM LOW OVER THE RENO-TAHOE AREA WHILE THE 00Z GEFS/GFS AND THE
CANADIAN ENSEMBLE BRING A MUCH WEAKER LOW INTO THE REGION. THE
FORMER SOLUTION WOULD BRING A CHANCE OF SHOWERS AS FAR SOUTH AS
INTERSTATE 80 WITH TEMPERATURES ONLY GETTING INTO THE 60S FOR LOWER
VALLEYS WHILE THE LATTER SOLUTION(S) WOULD KEEP PRECIP LIMITED TO
EXTREME NORTHERN NEVADA AND CALIFORNIA WITH MUCH WARMER TEMPERATURES
EARLY NEXT WEEK. FOR NOW, I HAVE SIDED WITH THE MORE PREVALENT
WEAKER SOLUTIONS FOR DRIER AND WARMER CONDITIONS. SNYDER
&&
.AVIATION...
VFR CONDITIONS WITH LIGHT WINDS (BELOW 10 KTS ALL TERMINALS) THRU
MID THURSDAY MORNING UNDER HIGH PRESSURE ALOFT. WINDS INCREASING
THURSDAY AFTERNOON AND EVENING AS LOW PRESSURE OFF CALIFORNIA COAST
EJECTS INLAND. SNYDER
&&
.FIRE WEATHER...
RIDGE OF HIGH PRESSURE WILL PASS OVER THE SIERRA AND WESTERN
NEVADA TODAY, THEN QUICKLY BREAK DOWN THURSDAY AS A STRONG LOW
DEVELOPS IN THE NORTHEAST PACIFIC. THIS LOW IS LIKELY TO PRODUCE
BREEZY TO WINDY CONDITIONS THROUGH THE WEEKEND.
AN INITIAL TROUGH WILL REACH NORTHERN CALIFORNIA THURSDAY WITH A
95-100 MPH JET STREAM ALOFT. A STRONG THERMAL GRADIENT NEAR 20
DEGREES WILL DEVELOP THURSDAY AFTERNOON BETWEEN THE LAKE TAHOE
BASIN AND THE CARSON-HUMBOLDT SINKS. POSITION OF THE JET AND
STRENGTH OF THE THERMAL GRADIENT BRINGS A HIGH AMOUNT OF CONFIDENCE
IN 30-40 MPH GUSTS WILL COMBINE WITH LOW HUMIDITY FOR THE LOWER
ELEVATIONS OF THE TAHOE BASIN, EASTERN LASSEN COUNTY, NORTHERN
WASHOE COUNTY AND THE SIERRA FRONT. THUS A FIRE WEATHER WATCH WILL
BE ISSUED THIS MORNING. A PERIOD OF GUSTY WINDS AND LOW HUMIDITY
WILL ALSO IMPACT LYON, NORTHERN MONO, AND THE WESTERN PORTIONS OF
PERSHING AND CHURCHILL COUNTIES THURSDAY AFTERNOON AND EVENING.
HOWEVER, THE DURATION OF GUSTY WINDS IS LESS CERTAIN THAN FOR THE
SIERRA FRONT, SO FOR NOW WILL JUST HIGHLIGHT IN THE PLANNING FORECAST
FOR ZONES 273, 453, AND 459.
HUMIDITY RECOVERIES ON THE MID SLOPES WILL BE POOR THURSDAY NIGHT AS
WINDS WILL NOT COMPLETELY DECOUPLE. BY LATE FRIDAY A STRONGER JET
STREAM WILL LIFT ACROSS NORTHEAST CALIFORNIA WITH A CONTINUED
STRONG THERMAL GRADIENT OVER THE AREA. THERE IS A BETTER POTENTIAL
FOR CRITICAL FIRE WEATHER CONDITIONS FRIDAY SOUTH OF HIGHWAY 50.
NORTH OF HIGHWAY 50, A BAND OF MOISTURE WITH COOLER TEMPERATURES
WILL BRING HIGHER HUMIDITY AND DECREASE THE THREAT FOR CRITICAL
CONDITIONS.
WINDY CONDITIONS WILL CONTINUE INTO SATURDAY WITH THE LOWEST
HUMIDITY VALUES OVER MONO AND MINERAL COUNTIES, WITH A CHANCE OF
SHOWERS IN THE NORTHERN SIERRA AND WESTERN LASSEN COUNTIES.
