AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
208 AM PDT WED AUG 12 2015

.SYNOPSIS...

LOW PRESSURE OFF THE CALIFORNIA COAST WILL LEAD TO LOCALLY BREEZY
CONDITIONS TODAY, WITH STRONGER WINDS THURSDAY AS THE LOW MOVES
INTO OREGON. MUCH LOWER HUMIDITY IS FORECAST THURSDAY YIELDING
CRITICAL FIRE WEATHER CONDITIONS. HOT AND DRY THIS WEEKEND WITH
CLEAR SKIES AND LIGHTER WINDS. GOOD VIEWING IS FORECAST FOR THE
PERSEID METEORS LATE TONIGHT.

&&

.SHORT TERM...

AN OFFSHORE LOW-PRESSURE SYSTEM WILL SHIFT EASTWARD THROUGH
THURSDAY BRINGING INCREASING SOUTHERLY FLOW OVER THE SIERRA AND
WESTERN NV. SMOKE FROM THE ROUGH WILDFIRE (NEAR KINGS CANYON) WILL
CONTINUE TO BE TRANSPORTED NORTHWARD, AND, DEPENDING ON THE
INTENSITY OF THE FIRE, THERE IS POTENTIAL FOR HAZE AND POSSIBLY
DENSE SMOKE TO IMPACT MONO COUNTY THIS MORNING AND AGAIN THURSDAY
MORNING.

WATER VAPOR SATELLITE IMAGERY SHOWS VERY DRY AIR ALOFT FROM THE
SOUTH CURRENTLY NOSING INTO THE EASTERN SIERRA AND WESTERN NV. A
VERY DRY AIR MASS IS ALREADY IN PLACE TODAY, BUT BY THURSDAY
AFTERNOON AN UPPER JET AND A DEEP MIXING LAYER WILL CREATE EVEN
DRIER CONDITIONS ALONG WITH GUSTY WINDS. EXPECT GUSTS IN VALLEYS
TO INCREASE TO 30-40 MPH THURSDAY AFTERNOON. FOR SIERRA RIDGES,
STRONG GUSTS ARE LIKELY TO START LATE WEDNESDAY NIGHT INCREASING
TO 50-60 MPH BY THURSDAY AFTERNOON. SEE THE FIRE WEATHER
DISCUSSION BELOW FOR DISCUSSION OF THESE CRITICAL FIRE WEATHER
CONDITIONS.

THESE WINDS WILL ALSO CREATE ROUGH CONDITIONS ON AREA LAKES
THURSDAY AFTERNOON AND WILL BRING THE POTENTIAL FOR LOW VISIBILITY
DUE TO BLOWING DUST, ESPECIALLY DOWNWIND OF DESERT SINKS ACROSS
WESTERN NV.

BY FRIDAY AFTERNOON THE UPPER JET HAS MOVED NORTH OF THE OREGON
BORDER AND THE SIERRA-TO-BASIN THERMAL GRADIENT HAS WEAKENED.
RELATIVE HUMIDITY REMAINS CRITICALLY LOW BUT WINDS WILL BE LIGHTER
WITH VALLEYS GUSTING UP TO 20 MPH AND RIDGES 30-40 MPH. JCM

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

PRIMARY CHANGES TO THE EXTENDED THIS FORECAST PERIOD WERE TO
INCREASE WINDS FOR MONDAY AND TUESDAY AS MODELS INDICATE A TROUGH OF
LOW PRESSURE AFFECTING THE REGION ONE OR BOTH OF THOSE DAYS.

MEDIUM RANGE MODELS ARE IN DECENT AGREEMENT SATURDAY AND SUNDAY AS A
LONG WAVE TROUGH NORTH OF THE REGION SLOWLY MOVES AWAY AND ALLOWS
RIDGE TO BEGIN BUILDING. THIS SHOULD RESULT IN LIGHTER WINDS...
EXCEPT TYPICAL AFTERNOON WINDS ALONG THE SIERRA FRONT...AND HIGH
TEMPERATURES ABOVE NORMAL EACH DAY. WE COULD APPROACH 100 DEGREES IN
THE BASIN AND RANGE BY SUNDAY.

BY MONDAY BOTH THE ECMWF AND GFS OPERATIONAL MODELS SHOW ANOTHER
LONG WAVE TROUGH DROPPING SOUTH INTO THE PAC NW WITH AN INCREASE IN
LOW TO MID LVL FLOW AS FAR SOUTH AS THE NORTHERN THIRD OF OUR CWA.
THE GFS IS A BIT MORE AGGRESSIVE EARLY ON THAN THE ECMWF BUT THEN
THE ECMWF DROPS THE TROUGH THROUGH FASTER MONDAY EVENING. THE GFS
STRENGTHENS AND SLOWS THE TROUGH CAUSING TUESDAY TO BE A BREEZY DAY.
MOST OF THE GEFS ENSEMBLE MEMBERS ARE LESS AGGRESSIVE WITH BRINGING
THE TROUGH DOWN INTO OUR AREA. THIS LEADS TO A FAIRLY LOW CONFIDENCE
FORECAST FOR MONDAY AND TUESDAY. WILL ERR ON THE SIDE OF CAUTION AND
SHOW A SLIGHT INCREASE IN WINDS EACH DAY...BUT NO WHERE CLOSE TO
GUIDANCE. MONDAY WOULD ALSO HAVE ABOVE AVERAGE HIGH TEMPERATURES
MOST AREAS WHILE TUESDAY COOLS A BIT.

NO POPS FOR THE ENTIRE EXTENDED FORECAST ALTHOUGH EARLY IN THE
FORECAST THERE COULD BE DECENT CU BUILD UPS AS MOISTURE TRIES TO
SNEAK UNDER THE RIDGE. 20

.AVIATION...

PRIMARY AVIATION HAZARD TODAY WILL BE REDUCED VISIBILITY IN HAZE
DOWNSTREAM FROM WILDFIRES. MOST NOTABLY THIS SHOULD OCCUR NEAR
KMMH...BUT THERE'S ALSO A POSSIBILITY OF LOWERING VSBYS OVER CENTRAL
NV AND FAR NORTHERN CALIFORNIA. GUSTY AFTERNOON BREEZES TODAY AS
GRADIENT STARTS TO INCREASE. FAVORED SOUTH TO NORTH ORIENTED VALLEYS
COULD SEE SOUTHERLY GUSTS APPROACH 25 KTS WHILE SIERRA AND WESTERN
NEVADA TERMINALS COULD SEE WSW GUSTS FROM 20-25 KTS.

BIGGER WIND IMPACT WILL BE LATE TONIGHT INTO THURSDAY. RIDGE WINDS
PICK UP OVERNIGHT AND TURBULENCE BEGINS TO INCREASE. AN APPROACHING
LOW AND INCREASING GRADIENT WILL PRODUCE GUSTY SURFACE WINDS
THURSDAY AFTERNOON AND EVENING WITH THE STRONGER GUSTS APPROACHING
35 KT OVER THE FAR NORTHERN FORECAST AREA NORTH OF HIGHWAY 50. THESE
WINDS DECREASE BY FRIDAY MORNING. 20

&&

.FIRE WEATHER...

FIRE WEATHER WATCH FOR THURSDAY STILL LOOKS REASONABLE AS FORECAST
SOUNDINGS OVER THE NORTHERN HALF OF THE FORECAST AREA HAVE THE
POTENTIAL TO MIX DOWN WINDS OF 35-40 MPH BY LATE AFTERNOON FOR
NORTHEAST CALIFORNIA AND NORTHWEST NEVADA. ALONG THE SIERRA FRONT
WINDS OF 30-35 MPH MAY MIX DOWN. THESE GUSTY WINDS ARE LIKELY TO
EXTEND SOUTH INTO NORTH MONO COUNTY AND EAST INTO THE AREA OF THE
BASIN AND RANGE OF NEVADA WEST OF HIGHWAY 95. WILL NOT EXTENDED THE
WATCH TO THOSE AREAS AS THEY CONSTITUTE SMALL AREAS OF THOSE ZONES
AND WE HAVE A LOWER CONFIDENCE THE STRONGER GUST WILL OCCUR THERE.

ALONG WITH THE INCREASED GRADIENT WINDS FOR THURSDAY...HUMIDITY
VALUES WILL BE QUITE LOW AS A SIGNIFICANT DRY SLOT WORKS INTO
NORTHEAST CALIFORNIA AND FAR WESTERN NEVADA. IF MODELS HOLD THEIR
CURRENT TRENDS WE WILL BE UPGRADING TO A RED FLAG WARNING FOR
THURSDAY FOR THE AREAS CURRENTLY UNDER THE WATCH AND WE MAY HAVE TO
INCLUDE A FEW AREAS OUTSIDE THE CURRENT WATCH AS WELL. 20
