AREA FORECAST DISCUSSION UPDATED
NATIONAL WEATHER SERVICE ELKO NV
214 PM PDT SUN JUL 23 2006

.SYNOPSIS...ABUNDANT MONSOON MOISTURE WILL BRING A GOOD THREAT OF
SHOWERS AND THUNDERSTORMS TO NORTHERN AND CENTRAL NEVADA INTO THE
EARLY PART OF THE WEEK. SOME DRIER AIR WILL MOVE INTO NORTHERN
NEVADA BY MID-WEEK FOR A DIMINISHING THREAT OF THUNDERSTORMS.
&&

.SHORT TERM...UPPER HIGH CENTERED OVER UTAH CONTINUES TO FEED
ABUNDANT MONSOON MOISTURE INTO NORTHERN AND CENTRAL NV THROUGH
MONDAY. THE GFS MODEL INDICATE A LITTLE DRYING OVER NWRN NV TUESDAY
AS WEAK SHORT WAVE MOVING INTO THE PAC NW ADVECTS IN SOME DRIER AIR.
HOWEVER THE NAM/WRF MODEL IS WEAKER WITH THIS SHORT WAVE AND SHOWS
LITTLE IF ANY DRYING. WILL DECREASE POPS A LITTLE IN THE FORECAST
BUT NOT AS MUCH AS THE GFS INDICATES AND GO WITH SLGT CHC TSTMS NWRN
NV AND CHC TSTMS ELSEWHERE.  CEC

.LONG TERM...TUESDAY NIGHT THROUGH SUNDAY. LATEST GFS AND ECMWF RUNS
COMING INTO BETTER AGREEMENT REGARDING EPAC RIDGE/W COAST SHORTWAVE
TROF AND HIGH PRESSURE OVER THE DESERT SW STARTING OFF THE EXTENDED.
GFS SHOWS RIDGE AXIS OVER SOUTH-CENTRAL NV BY THU 00Z...PROVIDING
WESTERLY FLOW FOR MOST OF THE CWA. BY FRI 00Z AXIS SHIFTS SLIGHTLY
TO THE NORTH BRINGING NRLY FLOW AND DRYING PWS TO THE NORTHERN
HALF OF CWA. TREND FOR WED-FRI IS BASICALLY TO KEEP BEST
MOISTURE/INSTABILITY TOWARD SOUTHERN END OF CWA.

BY THE WEEKEND MEAN PATTERN BECOMES MORE PROGRESSIVE SETTING THE
STAGE FOR A DEEP AND ANOMALOUS LONGWAVE TROF TO ENTER THE PAC NW
COAST BY THE WEEKEND. NCEP ENSEMBLE AND HPC GUIDANCE SUGGEST A DEEPER
TROF THAN CURRENTLY PROGGED BY THE OPERATIONAL GFS. THIS SCENARIO
WOULD SUGGEST A DRIER AND WINDIER SW FLOW FOR OUR AREA. WILL KEEP AN
EYE ON LATER MODEL RUNS. RA

&&

.AVIATION...SHOWERS AND THUNDERSTORMS ARE EXPECTED THROUGHOUT ALL
TWEB ROUTES THIS AFTERNOON AND EARLY EVENING...WITH THE MOST ACTIVE
AREA BETWEEN ELY AND LAS VEGAS AS VERY MOIST UNSTABLE AIR MOVES IN
FROM THE EAST. &&

.LKN WATCHES/WARNINGS/ADVISORIES...NONE.
