AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
232 AM PDT TUE SEP 23 2014

.SYNOPSIS...
DEVELOPING LOW PRESSURE IN THE PACIFIC WILL BRING INCREASING
SOUTHWEST FLOW AND CONTINUED WARM AND DRY CONDITIONS THROUGH
WEDNESDAY. SMOKE FROM THE KING FIRE WILL CONTINUE TO AFFECT THE
TAHOE BASIN AND WESTERN NEVADA. THE LOW PRESSURE SYSTEM WILL MOVE
INLAND ON THURSDAY WITH COOLER TEMPERATURES AND POSSIBLE SHOWERS
FOR THE END OF THE WEEK.

&&

.SHORT TERM...
THERE IS REASONABLE AGREEMENT IN THE OPERATIONAL SUITE OF MODELS
THIS MORNING WITH REGARD TO INCOMING TROUGH AND COLD FRONT. THE
PATTERN IS FORECAST TO BEGIN AMPLIFYING WITH TROUGH LOCATED NEAR
130W BY WEDNESDAY AFTERNOON AND RIDGE SITUATED OVER THE CENTRAL
AND SOUTHERN ROCKIES. THIS WILL PLACE OUR AREA IN A GENERAL
SOUTHWEST FLOW ALOFT WITH TEMPERATURES REMAINING WELL ABOVE
NORMAL. THE MAIN JET WILL STILL BE WEST OF THE AREA BUT WINDS WILL
INCREASE A LITTLE EACH DAY AS WINDS ALOFT INCREASE AHEAD OF
TROUGH. WINDS COULD GUST AS HIGH AS 35 MPH MAINLY ACROSS NORTHEAST
CA AND NORTHWEST NV WEDNESDAY AFTERNOON WITH LOCAL GUSTS AROUND 30
MPH IN THE TAHOE BASIN AND SIERRA FRONT. SMOKE WILL CONTINUE TO BE
AN ISSUE AROUND THE TAHOE BASIN AND INTO WESTERN NEVADA AS
AFTERNOON ZEPHYR WINDS (TURNING MORE WESTERLY) OCCUR EACH
AFTERNOON AND EARLY EVENING. DEPENDING ON THE ACTIVITY OF THE
FIRE, SMOKE WILL RESULT IN LOWERING VISIBILITY AND DIMINISHING AIR
QUALITY FOR A TIME, BEGINNING IN THE TAHOE BASIN THIS MORNING OR
EARLY AFTERNOON AND THEN SPREADING INTO WESTERN NV DURING THE MID
TO LATE AFTERNOON. A DRIER AIRMASS WILL BE IN PLACE TODAY THROUGH
WEDNESDAY WHICH INCREASES THE POTENTIAL FOR INCREASED FIRE AND
SMOKE. THE DENSE SMOKE ADVISORY WILL REMAIN IN PLACE FOR TODAY BUT
MAY NEED TO BE EXTENDED INTO WEDNESDAY.

AS THE TROUGH APPROACHES THE COAST WEDNESDAY NIGHT AND THURSDAY,
THE UPPER JET WILL DROP SOUTHEASTWARD INTO NORTHERN CA AND
NORTHWEST NV WITH FRONTAL BOUNDARY PUSHING INTO NORTHEAST CA
WEDNESDAY NIGHT AND INTO WESTERN NV THURSDAY. A BAND OF SHOWERS
WILL LIKELY ACCOMPANY THE FRONT AS IT MOVES INTO THE NORTHERN
SIERRA LATE WEDNESDAY NIGHT AND THURSDAY MORNING AND THEN INTO
NORTHWEST NV DURING THE DAY THURSDAY. INSTABILITY IS MARGINAL AS
TEMPERATURES ALOFT REMAIN WARM (MAIN COLD POOL WITH UPPER LOW WILL
STILL BE LOCATED OFFSHORE). HOWEVER FORCING ALONG FRONT AND UPPER
JET MAY BE ENOUGH TO PRODUCE SOME LIGHT QPF AMOUNTS. ALL MODELS
INDICATE A FEW LIGHT SHOWERS MAY MAKE IT AS FAR SOUTH AS HIGHWAY
50 BY THURSDAY AFTERNOON. HOWEVER, THEY INDICATE BAND WILL FALL
APART QUICKLY AS MOISTURE BECOMES MORE LIMITED.

THE THERMAL GRADIENT WILL BE QUITE STRONG THURSDAY WITH WINDS
LIKELY PICKING UP OVER THE TAHOE BASIN AND SIERRA FRONT EARLY
THURSDAY AND SPREADING ACROSS MUCH OF THE AREA DURING THE
AFTERNOON. WINDS WILL LIKELY GUST TO AROUND 40 MPH WITH SIERRA
RIDGE GUSTS UP TO 80 MPH. WE HAVE NOT INCLUDED SMOKE BEYOND
WEDNESDAY, BUT GIVEN THE WESTERLY WIND DIRECTION ON THURSDAY, IF
THE FIRE CONTINUES TO BE ACTIVE, SMOKY CONDITIONS WOULD PERSIST
ANOTHER DAY. HOHMANN

.LONG TERM...FRIDAY THROUGH MONDAY...
FEW CHANGES MADE TO THE LONG TERM AS THE MODELS ARE COMING INTO
BETTER AGREEMENT ON THE TIMING OF THE UPPER LOW MOVING THROUGH THIS
WEEKEND. HOWEVER, THERE ARE SIGNIFICANT DIFFERENCES IN THE DETAILS
AND WHERE AN AREA OF DEFORMATION NORTH/NORTHEAST OF THE LOW MAY
DEVELOP. FOR NOW, ASIDE FROM A BAND OF PRECIP THAT ALL MODELS ARE
SHOWING ALONG THE SIERRA FRIDAY AFTERNOON/EVENING, IT IS DIFFICULT
TO FAVOR ONE AREA OVER ANOTHER. AS SUCH, WILL JUST KEEP CHANCE POPS
IN THE SIERRA FROM TAHOE NORTH FRIDAY AND A BROAD BRUSH SLIGHT
CHANCE OF PRECIP THROUGH THE WEEKEND. MOST MODELS ARE KEEPING THE
AREA OF DEFORMATION OVER EASTERN/NORTHEASTERN NEVADA SO REALLY DO
NOT FEEL LIKE GOING HIGHER THAN SLIGHT CHANCE.

THE COLD FRONT SHOULD BE CLEARING WESTERN NEVADA BY FRIDAY MORNING.
THEREFORE, WINDS WILL DIMINISH AND BECOME MORE NORTHWEST ALONG WITH
MUCH COOLER TEMPERATURES THAT WILL LAST THROUGH THE WEEKEND WITH THE
UPPER LOW OVERHEAD OR NEARBY. EXPECT TEMPS TO HOVER AROUND 70 IN
WESTERN NV VALLEYS AND IN THE LOW 60S IN THE SIERRA AND A LIGHT
NORTH BREEZE WILL MAKE IT FEEL A LITTLE COOLER. AS THE UPPER LOW
BEGINS TO PULL AWAY ON MONDAY, A SLOW WARMING TREND WILL COMMENCE
WITH HIGHS CLOSER TO AVERAGE.  WALLMANN

&&

.AVIATION...
KING FIRE SMOKE WILL CONTINUE TO PLAGUE THE TAHOE BASIN AND WESTERN
NEVADA SIERRA FRONT THE NEXT TWO DAYS AS THE FIRE IS EXPECTED TO
REMAIN ACTIVE. VIS THIS MORNING WILL BE 3-5SM IN SPOTS WHILE VFR IN
OTHERS. WITH THE SOUTHWEST FLOW, THICKER SMOKE WILL AGAIN RETURN
LATE MORNING TO THE TAHOE BASIN AND EARLY-MID AFTERNOON FOR
KCXP/KRNO. VIS TO REDUCE TO 1SM AT TIMES AFTER 18Z/21Z RESPECTIVELY.
EXPECT A RETURN TO MVFR VIS FOR KTRK/KTVL/KCXP/KRNO BY 05Z. A REPEAT
IS LIKELY ON WEDNESDAY.

OTHERWISE VFR CONDITIONS CONTINUE ELSEWHERE AS WINDS WILL BE SW AND
SLOWLY INCREASE TODAY WITH PEAK GUSTS 20-25 KTS. PEAK GUSTS WILL
BE AROUND 30 KTS FOR WEDNESDAY AFTERNOON. WALLMANN

&&

.FIRE WEATHER...
WINDS WILL INCREASE TODAY WITH PEAK GUSTS 25-30 MPH FROM THE
SOUTHWEST. HUMIDITY WILL CONTINUE TO LOWER, BUT MINIMUMS ARE
STILL EXPECTED TO REMAIN 15-25% THIS AFTERNOON.

TONIGHT, A DRY SLOT WILL MOVE THROUGH WITH POOR HUMIDITY RECOVERY
EXPECTED ON MID AND UPPER SLOPES IN THE SIERRA AND INTO EXTREME
WESTERN NEVADA. HUMIDITY ONLY LOOKS TO HIT AROUND 30% IN THESE
AREAS WITH THE DRY SLOT. WINDS THEN LOOK TO BE STRONGER ON
WEDNESDAY WITH THE STRONGEST CORE OF WINDS NORTH OF I-80. PEAK
GUSTS AROUND 35 MPH ARE LIKELY THERE FOR SEVERAL HOURS. HUMIDITY
APPEARS TO BE LOW ENOUGH AS THEY SHOULD DROP DURING THE AFTERNOON
AS THE DRY SLOT REMAINS. HOWEVER, LATEST GUIDANCE IS KEEPING MIN
RH HIGHER THAN PREVIOUS RUNS. THEREFORE, WILL CONTINUE THE WATCH
FOR ZONES 270-271-278-458 AND NOT UPGRADE TO A WARNING AT THIS
TIME. MORE LOCALIZED CONDITIONS ARE EXPECTED FURTHER SOUTH.

ON THURSDAY, THE DRY SLOT WILL SLOWLY MOVE EAST WHILE WINDS LOOK TO
PEAK DURING THE DAY. GUSTS TO 40 MPH ARE LIKELY FOR MUCH OF THE
AREA. HOWEVER, MOISTURE WILL BEGIN TO INVADE AND RH WILL LIKELY NOT
DROP BELOW 20% FOR MANY AREAS NORTH OF I-80/WEST OF U.S. 395. THERE
IS STILL THE POSSIBILITY THAT ZONES 273/453/459 MAY DROP TO NEAR
10%, BUT IT DEPENDS ON THE TIMING. THERE IS STILL ENOUGH UNCERTAINTY
TO NOT ISSUE A FIRE WEATHER WATCH AT THIS TIME FOR THOSE ZONES. WALLMANN
