REA

AREA FORECAST DISCUSSION...UPDATE
NATIONAL WEATHER SERVICE ELKO NV
623 AM PDT FRI SEP 4 2009

UPDATED FIRE WEATHER SECTION

.SYNOPSIS...HIGH PRESSURE WILL GRADUALLY GIVE WAY TO A PACIFIC
STORM SYSTEM TODAY. THIS WILL RESULT IN ISOLATED TO WIDELY
SCATTERED SHOWERS AND THUNDERSTORMS OVER MAINLY THE CENTRAL AND
EASTERN PORTIONS OF THE FORECAST AREA. WINDS WILL INCREASE DURING
THE WEEKEND RESULTING IN BREEZY CONDITIONS. AFTERNOON TEMPERATURES
WILL BE ABOVE NORMAL FOR TODAY...COOLING THROUGHOUT THE WEEKEND
AND BECOMING NEAR NORMAL BY SUNDAY.

&&

.SHORT TERM...TODAY THROUGH SATURDAY. A FEW CLOUDS CAN BE SEEN
MAINLY ACROSS THE CENTRAL PART OF THE STATE THIS MORNING. A WEAK
TROUGH IS SHOWING UP IN THE WATER VAPOR LOOP WEST OF CALIFORNIA AT
THIS TIME.

FOR TODAY...MODELS ARE SHOWING THE MID-LEVEL RIDGE CIRCULATION
WOBBLING AROUND SOUTHERN CALIFORNIA...MOVING SLIGHTLY EAST AND
SOUTH OVER BAJA CALIFORNIA. WEAK SOUTHWESTERLY FLOW WILL CONTINUE
ACROSS THE FORECAST AREA. MODEL SOLUTIONS IN THE SHORT TERM ARE
HAVING DIFFICULTY WITH MOISTURE HANDLING. THE NAM HAS BEEN THE
MOST AGGRESSIVE WITH PUSHING SUBTROPICAL MOISTURE NORTHWARD AHEAD
OF THE APPROACHING WEAK SHORTWAVE. MEANWHILE THE GFS AND EUROPEAN
HAVE BEEN LESS SO...WITH PW VALUES GENERALLY BETWEEN 0.50 AND 0.60
INCHES THROUGH 18Z...AND THEN SHOWING AN INCREASE TO ABOUT 0.60 TO
0.70. GFS ALSO SHOWING LIS OF -1 TO -2C FOR THE LATE MORNING TO
AFTERNOON PERIOD. THIS WILL LEAD TO ISOLATED TO WIDELY SCATTERED
THUNDERSTORMS FOR MUCH OF THE FORECAST AREA. PREVIOUS SHIFT HAS
ISSUED A FIRE WEATHER WATCH AND WILL LET THIS CONTINUE AS CONFIDENCE
IS NOT HIGH ENOUGH FOR AN UPGRADE TO RED FLAG WARNING. WAS HOPING
FOR BETTER MOISTURE PROFILE AND A LITTLE BIT MORE INSTABILITY FOR
THIS EVENT.

FOR SATURDAY...HIGH PRESSURE WILL GIVE WAY TO A LARGE AND DEEP
TROUGH THAT WILL BE DIGGING SOUTHEASTWARD TOWARDS THE PACIFIC
NORTHWEST. PRESSURE GRADIENT WILL TIGHTEN...RESULTING IN BREEZY TO
LOCALLY WINDY CONDITIONS. SOME DRIER AIR FROM THE WEST WILL ALSO
TRY TO WORK ITS WAY EAST...RESULTING IN THE CRITICAL FIRE WEATHER
CONDITIONS BEING MET. AS SUCH A FIRE WEATHER WATCH FOR HUMBOLDT
COUNTY HAS BEEN ISSUED. IN THE EAST...WIDELY SCATTERED SHOWERS AND
THUNDERSTORMS WILL BE POSSIBLE AS A COLD FRONT PUSHES EAST LATE
SATURDAY.

.LONG TERM...SATURDAY NIGHT THROUGH NEXT THURSDAY. TROUGH PUSHING
INTO THE PAC NW TO BEGIN THE LONG TERM PERIOD WILL BRING GUSTY WINDS
TO NORTHERN AND PORTIONS OF CENTRAL NEVADA SUNDAY AND MONDAY
AFTERNOONS. ALSO EXPECT INCREASING MID AND HIGH CLOUDS ACROSS
NORTHERN NEVADA INTO EARLY NEXT WEEK BEFORE THE TROUGH EXITS TO THE
NORTHEAST LATE MONDAY. THE EXPECTED INCREASE IN CLOUDS ACROSS THE
NORTH SHOULD HELP KEEP OVERNIGHT LOWS SLIGHTLY ABOVE NORMAL...AND
ALSO BRING A BRIEF COOLING TO THE AFTERNOON HIGH TEMPS. WEAK FLOW IS
EXPECTED OVER THE GREAT BASIN MID-WEEK...WITH HIGH PRESSURE BUILDING
FOR THE LATTER PART OF NEXT WEEK.

&&

.AVIATION...AFTERNOON AND EVENING CONVECTION IS EXPECTED ACROSS MOST
OF CENTRAL AND NORTHEASTERN NEVADA TODAY. RAIN SHOULD BE LIMITED
WITH ANY THUNDERSTORM ACTIVITY...HOWEVER MICROBURST WINDS OF 40-45
MPH ARE POSSIBLE THIS AFTERNOON. NOT EXPECTING ANY THUNDERSTORM
ACTIVITY AT KWMC OR KTPH TODAY. HOWEVER KEKO WILL HAVE A SLIGHT
CHANCE OF TS...WITH ELY HAVING THE HIGHEST PROBABILITY OF TS
ACTIVITY.

&&

.FIRE WEATHER...AN APPROACHING TROUGH FROM THE WEST COUPLED WITH
HIGH PRESSURE IN THE SOUTH WILL BRING SOUTHWEST FLOW TO THE STATE
TODAY. SOME MOISTURE AND INSTABILITY WILL ALLOW FOR THUNDERSTORM
FORMATION...AND AS A RESULT...A FIRE WEATHER WATCH HAS BEEN ISSUED
FOR FWX ZONES 454-469-470. CONFIDENCE IS NOT HIGH ENOUGH AT THIS
TIME FOR A RED FLAG WARNING FOR THESE ZONES. FOR TOMORROW HIGH
PRESSURE WILL GIVE WAY TO A LARGE AREA OF LOW PRESSURE PUSHING
EAST TOWARDS THE PACIFIC NORTHWEST. THIS WILL BRING BREEZY TO
WINDY CONDITIONS TO PORTIONS OF THE AREA. ALSO...RH VALUES ARE
EXPECTED TO DIP BELOW 15%. AS A RESULT A FIRE WEATHER WATCH WAS
ISSUED FOR ZONE 467. THE AFOREMENTIONED LOW PRESSURE SYSTEM WILL
MOVE ACROSS THE NORTHERN TIER OF THE UNITED STATES DURING THE
WEEKEND...AND AN ADVANCING COLD FRONT SATURDAY AND SUNDAY WILL ALLOW
FOR COOLER TEMPERATURES ON SUNDAY. FOR SUNDAY...AREAS ACROSS
NORTHERN NEVADA...SUCH AS ELKO...WHITE PINE...AND HUMBOLDT
COUNTIES...MAY BRIEFLY SEE RED FLAG CONDITIONS...BUT IT DOES NOT
APPEAR THE TIME CRITERIA WILL BE MET. THIS WILL NEED TO BE CLOSELY
MONITORED HOWEVER.
