AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ELKO NV
342 PM PDT MON AUG 27 2012

.SYNOPSIS...HIGH PRESSURE WILL RESULT IN MORE DRY WEATHER THIS
EVENING. HOWEVER...A PACIFIC LOW IS INCHING ITS WAY CLOSER TOWARDS
THE SILVER STATE AND WILL PRODUCE BREEZY WINDS TOMORROW AND
WEDNESDAY.

&&

.SHORT TERM...TONIGHT THROUGH WEDNESDAY. THE LONGWAVE PATTERN
FEATURES AN UPPER LEVEL HIGH CENTERED OVER COLORADO AND A
POSITIVE TILT TROF OFF THE PACIFIC COAST. THE RESULTING SOUTHWEST
FLOW WILL BE DRY AND KEEP A LID ON CONVECTIVE DEVELOPMENT THIS
FORECAST PERIOD. SENSIBLE WEATHER-WISE...AS THE FRONT MOVES CLOSER...
THE PRESSURE GRADIENT WILL INCREASE...RESULTING IN BREEZY WINDS.

.LONG TERM...WEDNESDAY NIGHT THROUGH NEXT MONDAY. HURRICANE ISAAC
MODEL FORECAST WILL INFLUENCE OUR AREA AS WHERE AND HOW MUCH
MOISTURE THE MODELS PLACE IN EASTERN NV DURING THE LONG TERM. THE
LATEST GFS HAS MUCH MORE MOISTURE THAN THE 06Z RUN. MODELS ARE IN
FAIRLY GOOD AGREEMENT WITH THE OVERALL PATTERN THROUGH THURSDAY
MORNING...THEN DIFFER ENOUGH TO AFFECT EASTERN NV. LOW PRESSURE
OVER PACIFIC NORTHWEST AND HIGH PRESSURE TO EAST WILL CREATE
SOUTHWESTERLY FLOW OVER MOST OF THE CWA. THE LATEST GFS HINTING AT
MORE INSTABILITY FOR THUNDERSTORMS IN EASTERN ZONES...THEREFORE
HAVE BUMP POPS SLIGHTLY EACH AFTERNOON THURSDAY AND FRIDAY. TROF
AXIS SHOULD PUSH ALONG THE WEST COAST SUNDAY WHICH SHOULD BRING
BREEZY AND DRY CONDITIONS TO THE ENTIRE CWA SUNDAY AND MONDAY.
WITH THE CWA UNDER SOUTHWEST FLOW ALOFT...TEMPERATURES LOOK TO
REMAIN 3 TO 7 DEGREES ABOVE NORMAL THROUGH THE PERIOD.

&&

.AVIATION...VFR CONDITIONS ARE EXPECTED DURING THE NEXT 24
HOURS...EXCEPT OCCASIONALLY LOWERING TO NEAR 4SM AT KWMC DURING THE
OVERNIGHT AND MORNING HOURS DUE TO SMOKE. AS A TROF MOVES ALONG THE
WEST COAST ON TUESDAY...BREEZY WINDS WILL DEVELOP IN THE AFTERNOON.

&&

.FIRE WEATHER...THE LATEST WATER VAPOR IMAGE IS PRETTY
IMPRESSIVE...DEPICTING A DRY SWATH FROM JACKPOT TO THE SIERRA. THE MODELS
KEEP THE PWS UNDER .30 OF AN INCH FOR 467...468...469...470...AND
454 THE NEXT SEVERAL DAYS. BY WEDNESDAY...THE PWS CREST NEAR .50
OF AN INCH OVER PORTIONS OF 457 AND 455. SUFFICE TO SAY...POOR RH
RECOVERY AT NIGHT AND NO CONVECTION EXPECTED FOR THE REMAINDER OF
TODAY AND TOMORROW. THE CENTER OF CIRCULATION AT THE SURFACE FOR THE
LOW PRESSURE SYSTEM IS JUST WEST OF VANCOUVER ISLAND WITH THE 500
MB TROF AXIS WELL OFF THE COAST. THIS HAS ENABLED DRY SOUTHWEST
FLOW TO SET UP OVER MUCH OF NEVADA AND WILL BE PERSISTENT UNTIL
THE SHORTWAVE GETS EJECTED OUT OF THE SYSTEM AND PASSES THE SILVER STATE.
A WELL-DEFINED PRESSURE GRADIENT WILL SET UP BETWEEN PORTLAND AND
DENIO BY 18Z TOMORROW...RESULTING IN BREEZY CONDITIONS.

&&

.LKN WATCHES/WARNINGS/ADVISORIES...
FIRE WEATHER WATCH FROM TUESDAY MORNING THROUGH TUESDAY EVENING
FOR HUMBOLDT COUNTY...NORTHEASTERN NYE COUNTY...NORTHERN LANDER
COUNTY AND NORTHERN EUREKA COUNTY...NORTHWESTERN NYE COUNTY...
