AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ELKO NV
859 AM PDT TUE AUG 4 2009

.SYNOPSIS...A STRONG PACIFIC STORM SYSTEM FOR THIS TIME OF THE YEAR
WILL APPROACH THE GREAT BASIN REGION THIS WEEK...RESULTING IN
WINDY CONDITIONS AND A RISK OF THUNDERSTORMS THROUGH THURSDAY. AS
THE LOW PRESSURE SYSTEM MOVES THROUGH THE SILVER STATE LATE THIS
WEEK...A STRONG COLD FRONT WILL BRING MUCH COOLER TEMPERATURES
AND A CHANCE OF RAIN BY FRIDAY AND INTO NEXT WEEKEND...ESPECIALLY
ACROSS NORTHERN NEVADA.
&&

.UPDATE...BASED ON LATEST GUIDANCE...PARTICULARLY THE 12Z NAM...HAVE
CANCELLED THE FIRE WEATHER WATCH FOR TODAY FOR CENTRAL NEVADA. DRY
LIGHTNING COVERAGE NO LONGER APPEARS AS IF IT WILL REACH RED FLAG
WARNING CRITERIA TODAY. NO OTHER CHANGES AT THIS TIME.

...PREVIOUS DISCUSSION /ISSUED 203 AM PDT/...

.SHORT TERM...TODAY THROUGH WEDNESDAY...CURRENT IR SATELLITE LOOP
SHOWS HIGH CLOUDS PUSHING ACROSS THE CNTRL AND NE NV THIS MORNING
FROM THE SOUTHWEST. BELIEVE THESE CLOUDS WILL REMAIN OVER THE AREA
AT LEAST THROUGH THE MORNING...KEEPING LOW TEMPS ON THE HIGH SIDE
AND GENERALLY IN THE 60S TO NEAR 70. MODELS CONTINUE TO SHOW THE
UPPER LEVEL LOW OFF THE CALIF COASTLINE SLOWLY DRIFTING EAST
TODAY...WITH SOME MIDLEVEL SUBTROPICAL MOISTURE PUSHING NORTH INTO
NV BY THIS AFTERNOON. EXPECT SOME TSTORM ACTIVITY OVER PORTIONS OF
CNTRL AND POSSIBLY NRN NV THIS AFTERNOON...BUT IF THE HIGH LEVEL
CLOUD DECK REMAINS OVER THE AREA LONGER THAN EXPECTED...CONVECTION
MAY BE LIMITED TO WESTERN ZONES. KEPT TSTORMS IN THE FORECAST WITH A
STRONG 70-80 KT JET PUSHING INTO THE AREA AND MODELS CONTINUING TO
SHOW SOME LLVL INSTABILITY ALONG HIGHWAY 50 AND JUST SOUTH OF I80.
TSTORMS ARE EXPECTED TO PRODUCE LITTLE IF ANY RAINFALL WITH GUSTY
OUTFLOW WINDS POSSIBLE. LOWS WEDNESDAY MORNING WILL REMAIN MILD
WITH AMPLE CLOUD COVER EXPECTED.

FOR WEDNESDAY...MODELS SHOW THE UPPER LEVEL LOW APPROACHING THE NRN
CALIF COASTLINE AS THE FEATURE STARTS TO INCREASE IN FORWARD
SPEED. WITH THE MIDLEVEL PRESSURE GRADIENT INCREASING ACROSS THE
REGION AS THE LOW DRIFTS EASTWARD AND MODELS SHOWING 700 MB WINDS
AROUND 25 KTS...EXPECT WINDS TO INCREASE WEDNESDAY AFTERNOON WITH
SOUTH TO SOUTHWEST WINDS OF 20 TO 30 MPH...AND GUSTS UP TO 40
MPH ACROSS CNTRL NV. TSTORM ACTIVITY WILL SPREAD FURTHER NORTH
ACROSS ALL OF NRN NV WITH PW/S APPROACHING 1 INCH AND DECENT JET
DYNAMICS ALOFT. SOME DRIER AIR WILL MOVE INTO CNTRL NV...LIMITING
TSTORM COVERAGE.

.LONG TERM...WEDNESDAY NIGHT THROUGH MONDAY. GOOD GENERAL
AGREEMENT WITH THE MODELS THROUGH MONDAY. UPPER LEVEL LOW OFF THE
PACIFIC COAST ATTM WILL BE MOVING INLAND OVER CALIFORNIA WEDNESDAY
NIGHT AND THURSDAY. PRESSURE GRADIENT WILL BE TIGHTENING AND
BREEZY TO WINDY CONDITIONS ARE EXPECTED ACROSS MUCH OF THE CWA.
LOW WILL BE BRINGING IN A SLUG OF DRIER AIR FOR EASTERN NV IN THE
SW FLOW ALOFT ON THURSDAY. HOWEVER AS CENTRAL LOW PRESSURE DROPS
IN OVER NW NV ON THURSDAY NIGHT AND FRIDAY...SOME MOISTURE IS
ANTICIPATED. TEMPERATURES SHOULD COOL ABOUT TEN DEGREES OVER THE
WEEKEND AS THE LOW MOVES THROUGH. AIR MASS WILL BE UNSTABLE
THURSDAY AND FRIDAY BUT AS FLOW TURNS MORE WESTERLY ON
SATURDAY...STABILIZATION IS EXPECTED. AS DRY AIR INFILTRATES THE
CWA SATURDAY THROUGH MONDAY...TEMPERATURES WILL ALSO BEGIN TO
REBOUND BACK TO NEAR 90 DEGREES DAYTIME.
&&

.AVIATION...VFR CONDITIONS ARE EXPECTED FOR THE NEXT 24 HOURS.
WINDS WILL INCREASE THIS AFTERNOON AND GUSTS IN THE 20S CAN BE
EXPECTED. ISOLATED THUNDERSTORMS ARE ALSO EXPECTED TO DEVELOP
ACROSS MUCH OF THE FORECAST AREA.
&&

.FIRE WEATHER.../SEE UPDATE ABOVE FOR LATEST CHANGES/...ACTIVE.
STRONG UPPER LEVEL LOW OFF THE CALIFORNIA COASTLINE WILL CONTINUE TO
SLOWLY PUSH EAST THIS WEEK...RESULTING IN POTENTIALLY HAZARDOUS FIRE
WEATHER CONDITIONS THROUGH THURSDAY. FOR TODAY...DO NOT EXPECT WINDS
TO MEET CRITERIA IN THE AFTERNOON WITH MODELS BACKING OFF ON WINDS
SPEEDS AND ESPECIALLY GUSTS. ALSO...WITH HIGH CLOUDS CURRENTLY OVER
THE AREA...EXPECT CLOUDS TO SUPPRESS LOW LEVEL MIXING THROUGH EARLY
THIS AFTERNOON. SO WILL CANCEL THE FIRE WEATHER WATCH FOR GUSTY
WINDS AND LOW HUMIDITIES. HOWEVER...MIDLEVEL MOISTURE IS EXPECTED TO
PUSH INTO CNTRL NV THIS AFTERNOON. THERE IS A DECENT POTENTIAL OF
SCATTERED HIGH BASED DRY THUNDERSTORMS WHICH COULD PRODUCE LARGE
AMOUNTS OF LIGHTNING. THEREFORE...WILL CONTINUE THE FIRE WEATHER
WATCH FOR DRY THUNDERSTORMS FOR ZONES 454...455...AND 457 THIS
AFTERNOON AND THIS EVENING. THE ONLY ISSUE IS THE TIMING OF THIS
HIGH LEVEL CLOUD DECK CURRENTLY PUSHING OVER THE AREA...WHICH MAY
RESULT IN HIGHER STABILITY AND INHIBIT CONVECTION THIS AFTERNOON.
WITH THIS IN MIND...WILL MONITOR THIS SITUATION TODAY FOR A POSSIBLE
RED FLAG WARNING FOR DRY THUNDERSTORMS.

WEDNESDAY AND THURSDAY LOOK TO BE THE BEST DAYS FOR STRONG GUSTY
WINDS AS THE LOW IS FORECAST TO PUSH INLAND BY THURSDAY
MORNING. EXPECT WINDS ACROSS CENTRAL AND NORTHEAST NV TO GUST
AROUND 35 MPH WITH SUSTAINED WINDS BETWEEN 15 TO 25 MPH WEDNESDAY
AFTERNOON. VERY WINDY CONDITIONS ARE POSSIBLE THURSDAY AS THE LOW
PUSHES INTO EASTERN CALIFORNIA...WITH THE POTENTIAL OF 25 TO 40
MPH SUSTAINED WINDS AND GUSTS UP TO 60 MPH IN ZONES 457...455 AND
MAYBE ZONES 469 AND 470 AS WELL. WILL CONTINUE THE FIRE WEATHER
WATCH FOR WEDNESDAY...BUT A RED FLAG IS VERY LIKELY FOR WINDS.
THERE IS ALSO THE POTENTIAL FOR DRY THUNDERSTORMS TO CONTINUE OVER
NORTHERN NEVADA WEDNESDAY AFTERNOON...BUT AT THIS TIME...MOST
THUNDERSTORMS APPEAR TO BE WET WITH PRECIPITABLE WATER ABOVE 0.75
INCHES TO NEAR 1 INCH. A FIRE WEATHER WATCH ON THURSDAY IS ALSO
LIKELY IN THE NEAR FUTURE AS WELL DUE TO STRONG WINDS

FOR LATE IN THE WEEK...MODELS SHOW THE STRONG UPPER LEVEL LOW
NEAR THE CALIFORNIA COASTLINE PUSHING INLAND...WITH MUCH COOLER
TEMPERATURES AND HIGHER HUMIDITIES EXPECTED OVER NEVADA BY THE
WEEKEND. TT
