AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ELKO NV
211 AM PDT SAT OCT 20 2007

.SYNOPSIS...A STRONG COLD FRONT WILL CONTINUE MOVING ACROSS EASTERN
NEVADA TODAY...BRINGING PERIODS OF RAIN AND SNOW SHOWERS TO MOST OF
THE REGION. SNOW LEVEL WILL LOWER TO THE VALLEY FLOORS AS
MUCH COLDER AIR MOVES INTO THE STATE. BY SUNDAY AFTERNOON HIGH
PRESSURE WILL BRING CLEARING SKIES AND WARMER CONDITIONS THAT WILL
LAST THROUGH THE MIDDLE OF NEXT WEEK. &&

.SHORT TERM...TONIGHT THROUGH MONDAY. MAIN FORECAST PROBLEM IS IN
THE FIRST TWO PERIODS WITH APPROACHING TROUGH. RAIN SHOWERS ALREADY
BECOMING FAIRLY WIDESPREAD OVER NWRN CWA THIS MORNING WITH PLENTY
OF COLD AIR MOVING IN FROM THE NW DURING THE DAY. MAIN AREA OF
SHOWERS THIS MORNING IS OUT AHEAD OF COLD FRONT AND BEING AIDED BY
RIGHT REAR QUAD OF 125+KT JET. AS UPPER TROUGH MOVES ACROSS AREA
THIS AFTERNOON...EXPECT PRECIP TO BECOME FAIRLY WIDESPREAD
ESPECIALLY OVER ELKO COUNTY WHERE LIS DROP BELOW ZERO AND UPPER
LEVEL DIVERGENCE CONTINUES AS LEFT EXIT REGION OF 150KT JET
APPROACHES. WENT WITH CATEGORICAL POPS OVER MUCH OF ELKO COUNTY
ALTHOUGH DO NOT EXPECT A LOT OF ACCUMULATION...GENERALLY 1 TO 2
INCHES IN THE VALLEYS WITH 3 TO 6 IN THE MOUNTAINS BUT UNDER SOME
OF THE HEAVY SNOW SHOWERS THAT WILL LIKELY DEVELOP SOME LOCALIZED
AMOUNTS OF 5 INCHES ARE POSSIBLE. FURTHER SOUTH INTO CENTRAL NV...
MOISTURE WILL NOT BE AS DEEP AND THINK HWY 50 WILL BE THE GENERAL
CUTOFF OF PRECIP. MOST OF THE PRECIP THAT FALLS WILL LIKELY BE RAIN
UNTIL AROUND NOON THEN CHANGING OVER TO SNOW SO AN INCH OR 2 AT BEST
IS EXPECTED WITH NORTHERN PORTIONS OF WHITE PINE AND EUREKA
COUNTIES HAVING BEST CHANCE AT THAT WITH THE MOUNTAINS LIKELY SEEING
2 TO 4. TEMPERATURES WILL BE VERY TRICKY TODAY WITH AREAS IN ELKO
COUNTY LIKELY HAVING HIGHS BY 15Z-18Z THEN FALLING OR HOLDING
STEADY IN THE MID TO UPPER 30S. FURTHER SOUTH WILL ALSO HAVE FALLING
TEMPERATURES BUT LIKELY A LITTLE LATER. W TO NW WINDS BEHIND THE
FRONT WILL INCREASE TO 15-25 MPH MOST AREAS BUT IN THE WENDOVER AREA
THINK 25 TO 35 MPH WITH HIGHER GUSTS ARE LIKELY THIS AFTERNOON AND
WILL GO WITH A WIND ADVISORY FOR THIS AREA.

SYSTEM WILL START MOVING OUT OVERNIGHT BUT MODELS SHOWING SOME
DECENT MOISTURE REMAINING OVER ELKO COUNTY IN THE H85-H70 LAYER SO
KEPT SOME CHANCE POPS GOING IN THE FAVORED UPSLOPE AREAS.  RAISED
LOWS A FEW DEGREES...ESPECIALLY NERN NV WHERE CLOUDS AND DEW POINTS
REMAINING IN THE MID TO UPPER 20S SHOULD KEEP LOWS FROM FALLING TOO
MUCH EVEN WITH SOME FRESH SNOW. UPPER RIDGE WILL START BUILDING IN
SUN AND MON BRINGING WARMER TEMPERATURES BACK TO THE REGION. LOOKS
LIKE DECENT CU FIELD SHOULD DEVELOP AT LEAST OVER NERN NV SUN WITH
NORTHERLY WINDS SHOULD KEEP HIGHS BELOW GUIDANCE. BY MON SHOULD SEE
HIGHS INCREASE ANOTHER 10-15 DEGREES WITH H70 TEMPS WARMING TO 5C
TO 7C ACROSS AREA ALTHOUGH WITH HIGH PRESSURE RIGHT OVERHEAD WILL
NOT BE ABLE TO MIX OUT COMPLETELY BUT SHOULD STILL SEE HIGHS INTO
THE UPPER 50S TO MID 60S. JMG

.LONG TERM...MONDAY NIGHT THROUGH FRIDAY. MODELS IN GOOD AGREEMENT
THAT A STRONG UPPER RIDGE WILL BE ANCHORED OVER THE WRN U.S. THROUGH
MOST OF NEXT WEEK FOR DRY WEATHER AND ABOVE NORMAL TEMPS. THE SYSTEM
FOR LATE NEXT WEEK NOW LOOKING LESS LIKELY THAT IT WILL BRING ANY
PRECIP CHANCES TO THE CWFA. ALTHOUGH THERE ARE SOME DISCREPANCIES
BETWEEN THE ECMWF AND THE GFS...BOTH ARE TRYING TO SHOW A SPLIT FLOW
PATTERN NEXT FRIDAY WITH A CUTOFF UPPER LOW ALONG/OFF THE WEST COAST
AND NORTHERN ENERGY MOVING THROUGH THE NORTHERN ROCKIES. THIS WOULD
LEAVE NORTHERN AND CENTRAL NV IN A DRY PATTERN...SO THEREFORE KEPT A
DRY FORECAST THROUGH THE LONG TERM. MCGEE
&&

.AVIATION...A COLD FRONT WILL BE MOVING ACROSS THE REGION TODAY
BRINGING SHOWERS TO NORTHERN NEVADA THIS MORNING THEN TO CENTRAL
NEVADA BY LATE MORNING AND AFTERNOON. CIGS AND VSBYS SHOULD REMAIN
VFR AT BOTH KWMC AND KEKO THROUGH MID-MORNING. COLDER AIR BEHIND
THE FRONT WILL CAUSE SNOW LEVELS TO LOWER TO VALLEY FLOORS BY LATE
MORNING WITH MVFR CONDITIONS POSSIBLE AT KWMC AND KEKO IN SCATTERED
SNOW SHOWERS THROUGH THIS AFTERNOON. SCATTERED SNOW SHOWERS WILL
DEVELOP AT KELY MAINLY AFTER 18Z TODAY WITH MVFR CONDITIONS POSSIBLE
IN ANY HEAVIER SNOW SHOWERS.  MCGEE

PM PDT FOR NVZ033.
