AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ELKO NV
346 AM PDT SAT SEP 5 2009

.SYNOPSIS...A WEAK AREA OF LOW PRESSURE WILL BE PUSHING ACROSS THE
STATE TODAY BRINGING SHOWERS AND THUNDERSTORMS TO MAINLY THE
EASTERN HALF OF THE FORECAST AREA. WINDS WILL BEGIN TO PICK UP IN
THE NORTHERN SECTIONS OF THE STATE AS A MUCH STRONGER LOW PRESSURE
CENTER IMPACTS THE PACIFIC NORTHWEST. THIS SYSTEM WILL TRAVERSE
EAST ALONG THE US-CANADIAN BORDER...RESULTING IN BREEZY TO WINDY
CONDITIONS ACROSS MUCH OF THE FORECAST AREA SUNDAY. AFTERNOON
TEMPERATURES WILL COOL EACH DAY THIS WEEKEND...DROPPING TO AT OR
JUST BELOW NORMAL BY THE BEGINNING PORTIONS OF NEXT WEEK.

&&

.SHORT TERM...TODAY THROUGH SUNDAY. WEAK DISTURBANCE CURRENTLY
CROSSING SOUTHERN NEVADA AT THIS HOUR AND IS CLEARLY DEPICTED ON
THE WATER VAPOR IMAGERY. YESTERDAYS ACTIVITY HAS HELPED TO
MOISTEN THE ATMOSPHERE. PER GPS-MET PRECIPITABLE WATER
MEASUREMENTS...AUSTIN HAS DROPPED A LITTLE AND IS AT 0.65 INCHES
WHEREAS ELKO IS SITTING AT ROUGHLY 0.80 INCHES OF PW. SOME DRIER
AIR IS TRYING TO WORK EAST THOUGH AND WITH A LARGER LOW PRESSURE
SYSTEM WORKING TOWARDS THE PACIFIC NORTHWEST...WINDS ACROSS THE
FORECAST AREA WILL INCREASE...MAINLY IN HUMBOLDT COUNTY TODAY. THE
RESULTING LOW RH VALUES AND WINDY CONDITIONS HAVE PROMPTED A RED
FLAG WARNING FOR FWX 467 FOR TODAY...AND WILL CONTINUE THROUGH
THIS EVENING. WITH A MORE MOIST AND UNSTABLE AIR MASS (LIS ARE
PROGGED TO BE -2 TO -3C) TO THE EAST...EXPECTING SHOWERS AND
THUNDERSTORMS TO DEVELOP LATER THIS MORNING AND AFTERNOON.
THINKING RIGHT NOW IS THAT STORMS WILL BE WET AS AIR MASS HAS
MOISTENED DUE TO ACTIVITY SEEN YESTERDAY. WE COULD STILL SEE SOME
GUSTY OUTFLOWS UP TO 50 MPH HOWEVER. AFTERNOON TEMPERATURES ARE
ANTICIPATED TO BE 2 TO 4 DEGREES COOLER TODAY AREA-WIDE.

FOR SUNDAY...THE STRONGER LOW PRESSURE SYSTEM IS FORECAST TO BE
JUST WEST OF THE COAST OF BRITISH COLUMBIA. STRONG WEST TO
SOUTHWEST WINDS WILL DEVELOP TOMORROW AFTERNOON...BUT RIGHT NOW IT
DOES NOT APPEAR WIND ADVISORY THRESHOLDS WILL BE MET. AIR MASS
WILL DRY SOMEWHAT AND NOT BE AS UNSTABLE...SO EXPECTING ISOLATED
THUNDERSTORMS AT BEST OVER THE EXTREME EASTERN SECTIONS OF THE
FORECAST AREA. DUE TO THE POSSIBILITY OF LOW RHS AND THE
AFOREMENTIONED STRONG WINDS...A FIRE WEATHER WATCH HAS BEEN ISSUED
FOR WHITE PINE COUNTY. ONCE AGAIN AFTERNOON TEMPERATURES ARE
EXPECTED TO BE A FEW DEGREES COOLER SUNDAY.

.LONG TERM...SUNDAY NIGHT THROUGH NEXT FRIDAY. BROAD TROUGH BRUSHES
ACROSS THE NORTHERN HALF OF THE CWA SUNDAY NIGHT THROUGH MONDAY
NIGHT...HOWEVER NO PRECIPITATION IS EXPECTED TO DO THE RELATIVELY
DRY AND STABLE CONDITIONS. DAYTIME TEMPERATURES NEAR NORMAL
MONDAY...THEN BECOME 5 TO 8 DEGREES ABOVE NORMAL FOR THE REMAINDER
OF THE WEEK AS HIGH PRESSURE BUILDS OVER AREA.

&&

.AVIATION...SKIES WILL BE MOSTLY CLEAR ACROSS WESTERN NEVADA TODAY.
ACROSS THE EASTERN MOST PORTIONS OF THE STATE HOWEVER...LINGERING
MOISTURE AND INSTABILITY WILL LEAD TO MOSTLY CLOUDY SKIES. ACROSS
THE NORTHEASTERN CORNER OF THE STATE SHOWERS AND THUNDERSTORMS ARE
EXPECTED BY THE LATE MORNING OR EARLY AFTERNOON HOURS. THUNDERSTORMS
ARE EXPECTED TO DIMINISH BY AROUND 00Z. GUSTY OUTFLOW WINDS ARE
EXPECTED NEAR THUNDERSTORMS...AND DOWNBURST WINDS OF 40-45 MPH ARE
POSSIBLE AS WELL...WHICH SHOULD BE GENERALLY CONFINED TO AREAS
NORTHEAST AND EAST OF THE RUBY MOUNTAIN RANGE.

&&

.FIRE WEATHER...A WEAK DISTURBANCE WILL PUSH ACROSS THE EASTERN
HALF OF THE STATE TODAY...WHILE A MUCH STRONGER AREA OF LOW
PRESSURE BEGINS TO BEAR DOWN FROM THE NORTHWEST. SHOWERS AND
THUNDERSTORMS ARE EXPECTED TO DEVELOP AS THIS WEAK DISTURBANCE
EXITS THE STATE TODAY. THINKING AT THIS TIME THAT THUNDERSTORMS
WILL BE WET AS YESTERDAYS STORMS HELPED TO MOISTEN THE
ATMOSPHERE. FURTHER WEST IN FWX 467...A RED FLAG WARNING HAS
ALREADY BEEN ISSUED. DRIER AIR WILL BE MOVING INTO THIS AREA LATER
TODAY...AND WITH WINDS INCREASING IN SPEED...CRITICAL FIRE WEATHER
THRESHOLDS ARE EXPECTED TO BE MET. ON SUNDAY...THE STRONGER AREA
OF LOW PRESSURE WILL MOVE CLOSER TO THE STATE...BRINGING BREEZY TO
WINDY CONDITIONS TO THE ENTIRE FORECAST AREA. A FIRE WEATHER WATCH
HAS BEEN ISSUED FOR FWX ZONE 455 FOR SUNDAY. FURTHER NORTH IN ELKO
AND HUMBOLDT COUNTIES...RH VALUES MAY BRIEFLY DECREASE TO LESS
THAN 15 PERCENT DURING THE DAY...ALONG WITH STRONG WINDS IN EXCESS
OF 30 MPH. HOWEVER...AS THESE LOCATIONS ARE CLOSER TO THE COOLER
AIR MASS FILTERING EASTWARD...THINKING RIGHT NOW IS THE TIME
THRESHOLD FOR A RED FLAG WOULD NOT BE MET. FOR MONDAY THE LOW
MOVES EAST OF THE STATE...BRINGING LESS WIND TO THE AREA. HIGH
PRESSURE IS ANTICIPATED TO BUILD DURING THE MID-WEEK
PERIOD...BRINGING ABOVE NORMAL TEMPERATURES AND LIGHT WINDS. &&

EVENING FOR NVZ467 FOR GUSTY WINDS AND LOW RELATIVE HUMIDITIES.
