AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ELKO NV
1245 PM PDT FRI AUG 20 2004

.SYNOPSIS...ABUNDANT MOISTURE OVER NEVADA WILL KEEP THE THREAT OF
SHOWERS AND THUNDERSTORMS IN THE AREA INTO THE WEEKEND. BREEZY
CONDITIONS WILL DEVELOP ON SUNDAY AS AN AREA OF LOW PRESSURE
APPROACHES FROM THE WEST. THIS LOW PRESSURE SYSTEM WILL BRING COOLER
WEATHER TO THE REGION THROUGH MOST OF NEXT WEEK.
&&

.DISCUSSION...ONCE AGAIN...NO SIGNIFICANT CHANGES TO SHORT TERM.
SUFFICIENT MOISTURE REMAINS IN PLACE FOR SHOWERS AND THUNDERSTORMS
THIS AFTERNOON THROUGH SATURDAY...SO WILL CONTINUE TO CARRY CHANCE
POPS ON SAT. HOWEVER...SLIGHTLY DRIER ON SATURDAY OVER HUMBOLDT AND
LACK OF UPPER SUPPORT...SO TRIMMED POPS BACK THERE.

CONVECTION A LITTLE SLOWER TO KICK OFF TODAY THAN YESTERDAY
BASED ON RADAR AND VIS IMAGERY. FORECAST SOUNDINGS FROM BOTH GFS/ETA
SHOW CAPE OVER 1000 J/KG AND LI/S OF -2 TO -5C TODAY AND SATURDAY.
FOR TODAY AND TONIGHT...CONVECTION WILL BE ENHANCED WITH UPSTREAM
VORT MAX. THIS WELL DEFINED VORT CENTER EVIDENT IN WV IMAGERY AND
LOCATED NEAR NV/OR/ID BORDER AT 18Z. 12Z MODELS DID NOT INITIALIZE
THIS FEATURE VERY WELL...WITH GFS TOO SLOW AND ETA ONLY SLIGHTLY
BETTER WITH POSITION. MODELS ALSO SHOW SEPARATE VORT CENTER NEAR
SOUTHERN CWA OVERNIGHT WITH SOME INSTABILITY IN PLACE SO WILL EXTEND
SLIGHT CHANCE POPS ACROSS MOST OF NORTHERN NYE ZONE.

BY SUNDAY...TROF BEGINS APPROACHING REGION FROM NW. CONTINUED TREND
OF LOWER POPS AS SW FLOW SETS UP BRINGING DRIER AIR INTO CWA.
WINDS WILL ALSO BECOME MORE OF AN ISSUE AS PRESSURE GRAD TIGHTENS UP.
H5 WINDS APPROACH 50 KTS OVER NW CWA BY 00Z MON. MOS GUIDANCE ALSO
GIVING VALUES IN 15-20 KT RANGE ON SUNDAY. WILL WORD FOR BREEZY
CONDITIONS. OTHERWISE...ECMWF...GFS AND ENSEMBLE MEMBERS CONTINUE TO
SUPPORT TROF OVER WESTERN CONUS THROUGH MOST OF NEXT WEEK. MAINTAINED
LOW POPS ACROSS THE NORTH AND COOLED TEMPS EARLY-MID WEEK IN RESPONSE
TO COOLER NW FLOW.
