AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
310 PM PDT WED SEP 12 2007

UPDATED TO INCLUDE FIRE WEATHER SEGMENT.

.SHORT TERM...
AN UPPER LOW LOCATED OFF THE WEST COAST NEAR 35N 130W WILL MOVE
NORTHEAST AND REMAIN NEARLY STATIONARY NEAR COASTAL AREAS OF NRN CA
AND OREGON THROUGH THE SHORT TERM. 85 KT JET SOUTH OF THE LOW WILL
HEAD FOR THE KSFO AND TAHOE AREAS BY THURSDAY. ASSOCIATED HIGH LEVEL
MOISTURE PLUME ASSOCIATED WITH THE JET IS EVIDENT MOVING INTO SRN
CA/NV THIS AFTERNOON. AS THE JET AND DYNAMICS NEAR THE AREA ON
THURSDAY ISOLATED TSTMS ARE EXPECTED OVER MINERAL/PERSHING/CHURCHILL
COUNTIES BY THE AFTERNOON...AND ALSO OVER NRN LASSEN/NRN WASHOE
COUNTIES WHERE THE CONV/DIV COUPLET SETS UP IN THE FAVORABLE LEFT
EXIT REGION OF THE JET. PW VALUES ARE LESS THAN 0.5 INCHES ACROSS
THE AREA...THEREFORE ANY TSTMS ARE EXPECTED TO BE DRY. ANOTHER
CONCERN WILL THE BE THE INCREASE FLOW AND SURFACE WIND AHEAD OF THE
SYSTEM. WIND GUSTS UP TO 30-35 MPH ARE LIKELY ACROSS THE AREA ON
THURSDAY...ESPECIALLY ALONG THE SIERRA AND EXTREME WRN NV. 700 MB
FLOW IS ONLY AROUND 15-20 KTS SO THERE IS SOME CONCERN AS TO HOW FAR
DOWN THE JET ALOFT WILL TRANSLATE. HOWEVER THE SURFACE GRADIENT WILL
BE FAIRLY STRONG WHICH SHOULD ALLOW GUSTS TO REACH 30 MPH OR
SLIGHTLY HIGHER. LAKE WIND ADVISORIES WILL BE IN EFFECT TOMORROW FOR
TAHOE AND PYRAMID. SEE FIRE WEATHER SECTION BELOW FOR MORE ON GUSTY
WINDS AND POTENTIALLY FAST MOVING DRY THUNDERSTORMS.

WINDS ON FRIDAY WILL STILL BE BREEZY...WITH GUSTS AROUND 30 MPH
LIKELY. LAKE WIND ADVISORIES MAY ALSO BE NEEDED FOR FRIDAY AS WELL.
WESTERLY FLOW SHOULD HELP TO STABILIZE AREAS SOUTH OF INTERSTATE 80.
HOWEVER A SHORT ROTATING INTO NRN LASSEN/NRN WASHOE COUNTIES MAY
TRIGGER A FEW SHOWERS OR THUNDERSTORMS OVER FAR NRN ZONES. MOST
CONVECTION IS EXPECTED TO BE PUSHED FURTHER NORTH INTO OREGON AND
IDAHO BY THE SHORT WAVE...THEREFORE WILL ONLY CARRY SHOWERS OVER
THOSE AREAS FOR NOW. SHOWERS MAY LINGER INTO SATURDAY ALONG THE
NV/OR BORDER...BUT SHOULD BE ISOLATED AT BEST.

TEMPERATURES WILL COOL SEVERAL DEGREES EACH DAY THROUGH FRIDAY AS
HEIGHTS AND THICKNESS VALUES FALL AS THE LOW APPROACHES AND WILL
FINALLY APPROACH NORMAL VALUES. TEMPERATURES WILL DROP INTO THE MID
80S ON THURSDAY...AND MAY STRUGGLE TO REACH 80 DEGREES IN SOME WRN
NV VALLEYS BY FRIDAY...HENCE A COUPLE DEGREES BELOW NORMAL. NEAR
NORMAL TEMPERATURES ARE EXPECTED TO CONTINUE THROUGH THE WEEKEND.
BENINATO

.LONG TERM...SUNDAY THROUGH WEDNESDAY...
BROAD UPPER TROUGH OVER THE WEST COAST WILL BE REINFORCED BY A
STRONG SHORTWAVE GOING INTO THE BEGINNING OF NEXT WEEK. THIS WILL
SERVE TO KEEP OUR TEMPERATURES FAIRLY COOL AND PLEASANT NEXT
WEEK...RIGHT AROUND NORMAL FOR THIS TIME OF YEAR.

TOWARD MID-WEEK...MED RANGE MODELS OVER THE LAST COUPLE DAYS...THE
GFS...UKMET AND ECMWF... ARE ALL INDICATING A STRONG SLIDER COMING
DOWN THE WEST COAST. THIS WILL AGAIN BRING COOLER AIR DOWN INTO THE
REGION. THERE IS ALSO A SLIGHT CHANCE THAT THIS SYSTEM MAY BRING
SOME PRECIP TO THE NORTHERN AND CENTRAL SIERRA.  HOON
&&

.AVIATION...
LOW IN THE PACIFIC WILL CONTINUE TO APPROACH THE NORTHERN CALIFORNIA
COAST TONIGHT...WITH INCREASING SOUTH TO SOUTHWEST FLOW ALOFT
THROUGH FRIDAY.  THIS WILL KEEP THE SMOKE/HAZE VISIBILITY
RESTRICTIONS FROM THE MOONLIGHT FIRE NORTH OF LINE FROM
SUSANVILLE-PYRAMID LAKE.

SURFACE WINDS ARE EXPECTED TO INCREASE THURSDAY WITH GUSTS UP TO
30KTS. 10-20 PERCENT CHANCE OF THUNDERSTORMS ON THURSDAY 80NM NORTH
OF KRNO-KTRK AND EAST OF PYRAMID LAKE-KRNO-MINDEN LINE.  HOON
&&

.FIRE WEATHER...
UPGRADED WATCH TO WARNING FOR ALL ZONES ORIGINALLY IN WATCH...AND
ALSO ADDED 459 SINCE THE UPPER LEVEL JET MAXIMUM IS EXPECTED TO PASS
OVER THE MINERAL AND MONO ZONES AND BE ACCOMPANIED BY VERY DRY LOW
AND MID LEVELS...RH AT SOME SITES IN THESE ZONES COULD DROP BELOW
5%. SINCE ZONE 270 WAS SURROUNDED BY WATCH OR WARNING ON ALL
SIDES...THEY WILL BE ADDED TO THE WARNING AS WELL. ONLY ZONE 453 IS
NOT IN A WARNING AT THIS TIME AS WINDS ARE LIKELY TO PICK UP TOO
LATE IN THE DAY TO MEET THE NEEDED DURATION CRITERIA FOR BOTH
HUMIDITY AND WINDS. FOR THE FAR NORTH AND FAR EAST ZONES...ISOLATED
FAST MOVING TSTMS MAY PRODUCE A FEW NEW FIRE STARTS LATE THURS
AFTERNOON...ALTHOUGH THE MOST LIKELY AREAS FOR TSTMS WILL BE OVER
CENTRAL NV AND NORTH OF THE OREGON BORDER. WINDS SHOULD BE JUST
BELOW CRITERIA BY FRIDAY AND DECREASE FURTHER ON SATURDAY AS LOW
PRESSURE FILLS AND GRADIENT WEAKENS. MJD
