AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE ELKO NV
1100 AM PST FRI NOV 30 2007

.SYNOPSIS...A WEAK LOW PRESSURE SYSTEM WILL BRING PARTLY CLOUDY SKIES
TO NORTHERN NEVADA TODAY. A LOW MOVING THROUGH ARIZONA AND UTAH
TONIGHT AND SATURDAY WILL BRING A CHANCE OF SNOW TO EASTERN AND
SOUTHERN WHITE PINE COUNTY. TEMPERATURES WILL CONTINUE ON THE COOL
SIDE THROUGH THE WEEKEND...WARMING MONDAY AND TUESDAY...WITH A SLIGHT
CHANCE OF SHOWERS FAR NORTH TUESDAY AND WEDNESDAY.
&&

.UPDATE...1100 AM PST...BAND OF SNOW MOVING ACROSS THE RENO CWA WITH
KLRX SHOWING SOME ECHOES EXTENDING INTO HUMBOLDT AND NORTHWESTERN
ELKO COUNTIES IN OUR OWN CWA. THIS SNOW IS ASSOCIATED WITH A POTENT
MIDLEVEL TROUGH CROSSING INTO NEVADA FROM CALIFORNIA AT THE
MOMENT...AND IS BEING ENHANCED BY THE RIGHT REAR ENTRANCE REGION OF
A POTENT UPPER-LEVEL JET STREAK CURRENTLY LOCATED OVER NORTHERN
NEVADA AND IDAHO. HAVE NOT RECEIVED ANY REPORTS OF SNOW ON THE
GROUND AS OF YET...BUT CONSIDERING THE MODERATE SNOW WHICH WAS
OBSERVED AT KRNO RECENTLY...DECIDED TO ADD ISOLATED AND SCATTERED
SNOW SHOWERS ACROSS HUMBOLDT COUNTY, ALONG WITH ADJACENT PARTS OF
ELKO AND LANDER COUNTIES. ALSO INCREASED CLOUD COVER ACROSS BOTH THE
NORTHWEST AND SOUTHEAST PARTS OF THE CWA BASED ON SATELLITE IMAGERY.
SAF...PFM...SFT...AND ZFP RE-SENT. RCM

.SHORT TERM...TODAY THROUGH SUNDAY. SHORT-TERM MODELS AGREE ON COLD
FRONT MOVING THRU THE FCST AREA TODAY AND THIS EVENING...WITH -7C
REACHING ELY THIS EVENING. PRECIP WILL SPREAD INTO SE WHITE PINE
LATE THIS AFTERNOON AND EVENING AS A STRONG STORM SYSTEM LIFTS THRU
ARIZONA INTO UTAH. A FEW INCHES OF SNOW WILL BE POSSIBLE IN SE WHITE
PINE AND NORTHEAST NYE...BEFORE THE STORM PULLS EAST SATURDAY
AFTERNOON AND EVENING. CONDITIONS WILL BE WINDY IN EAST CENTRAL NV
TODAY AND BREEZY ELSEWHERE.

AT 500MB...TROF ASSOCIATED WITH COLD FRONT  WILL BRUSH THE NORTH
TODAY...BUT LITTLE MOISTURE TO WORK WITH. A SECOND DRY TROF WILL
MOVE THRU THE NORTH SATURDAY...WITH ZONAL FLOW BRIEFLY LATE
SATURDAY NIGHT INTO SUNDAY. A RIDGE WILL BEGIN BUILDING IN FROM THE
WEST SUNDAY AFTERNOON. REA

.LONG TERM...SUNDAY NIGHT THROUGH NEXT THURSDAY. LATEST GFS AND
ECMWF MODEL RUNS IN REASONABLE AGREEMENT THROUGH EXTENDED PERIOD.
THEY SHOW WEAK RIDGING OVER THE STATE ON SUN EVENING ALONG WITH
INCREASING SWRLY FLOW ALOFT...H7 WINDS ON MON WILL BE 40-50 KTS SO
ADVISORY CRITERIA WILL HAVE TO BE WATCHED FOR WRN HALF OF CWFA. THIS
ALSO PORTENDS A WARMING TREND AS H7 TEMPS INCREASE TO 2-4 DEGS C IN
NORTH AND 6-8 DEGS C IN SOUTH ON MON PM. RESULTING DAYTIME TEMPS ON
MON WILL RISE INTO LOW 50S NORTH AND MID-UPPER 50S SOUTH. OVERNIGHT
LOWS ON TUES AM WILL ALSO BE ABOUT 3-5 DEGS WARMER THAN MON AM DUE
TO MILD H7 TEMPS AND INCREASING CLOUD COVER ASSOCIATED WITH
APPROACHING JET JUST NORTH OF CWFA.  BEGINNING TUES EVENING...A
SERIES OF H5 SHORTWAVES WILL AFFECT NRN PORTIONS OF CWFA. THE FIRST
SYSTEM ON TUES EVENING WILL BRING RAIN SHOWERS TO MAINLY
HUMBOLDT...ELKO AND NRN LANDER/EUREKA COUNTIES. GFS SHOWS NEXT
STRONGER SHORT WAVE ASSOCIATED WITH JET STREAM DIPPING INTO NRN NV
ON WED AM. COOLER AIR WILL ALSO PUSH INTO NRN PORTIONS OF CWFA BY
MIDDAY WED AS EVIDENCED BY H7 TEMPS DROPPING TO -6 TO -8 DEGS C AND
RESULTING SNOW LEVEL LOWERING TO SURFACE IN NRN VALLEYS.
HOWEVER...BY THIS TIME QPF AMOUNTS WILL BE LIGHT...LESS THAN 0.1
INCHES...SO LITTLE ACCUMULATION IS EXPECTED. AS THIS FEATURE AND
ASSOCIATED JET CORE ADVANCE EWRD LATE WED EVENING...ENTIRE CWFA WILL
TRANSITION TO COOLER NWRLY FLOW. AFTER A SHORT RESPITE...ANOTHER JET
STREAK AND ASSOCIATED SHORT WAVE WILL MOVE INTO CWFA ON THURS PM
WITH MINIMAL QPF AMOUNTS. ESSENTIALLY LEFT SLT CHC POPS UNCHANGED IN
NRN PORTIONS OF CWFA DURING ENTIRE PERIOD. AWG &&

.AVIATION...AN UPPER LEVEL DISTURBANCE WILL BE APPROACHING FROM THE
WEST BUT THE MAIN EFFECT WILL BE AN INCREASE IN MID AND UPPER LEVEL
CLOUD CEILINGS AS WELL AS GUSTY WINDS. EXPECT MOSTLY VFR CONDITIONS
THROUGHOUT THE STATE ON FRIDAY. HOWEVER...SNOW SHOWERS WILL BE
DEVELOPING IN/AROUND THE HIGHER ELEVATIONS OF SOUTHEASTERN NEVADA
NEAR KELY AND KTPH ON FRIDAY AFTERNOON AND EVENING...RESULTING IN
PERIODS OF MVFR CONDITIONS AS CEILINGS/VISIBILITIES INTERMITTENTLY
DROP TO AROUND 3000/5. BLUSTERY WINDS WILL ALSO OCCUR IN PORTIONS OF
NORTHERN AND EASTERN NEVADA WITH PEAK GUSTS REACHING 20-30
KNOTS...ESPECIALLY NEAR KELY. AWG
&&

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