AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ELKO NV
252 AM PDT MON APR 13 2009

.SYNOPSIS...HIGH PRESSURE WILL BE EXITING TODAY AND AS CLOUDS
INCREASE...SOME SHOWERS MAY DEVELOP...WITH POSSIBLY A THUNDERSTORM
IN THE AFTERNOON. A STRONG COLD FRONT WILL BEGIN MOVING THROUGH
THE REGION TUESDAY. WINDS WILL INCREASE AHEAD OF THE FRONT AND
RAIN WILL CHANGE TO SNOW TUESDAY NIGHT. SIGNIFICANT SNOWFALL WILL
BE POSSIBLE TUESDAY NIGHT AND WEDNESDAY. DRIER WEATHER WILL RETURN
BY FRIDAY.
&&

.SHORT TERM...TODAY THROUGH WEDNESDAY. QUIET NIGHT SO FAR. SOME
INCREASING CLOUDS SHOWING ON IR SATELLITE IMAGERY ACROSS THE
NORTHERN BORDER AREA AS THE PROGRESSIVE RIDGE BREAKS DOWN AND
MOVES EAST. VERY GOOD AGREEMENT BETWEEN THE SHORT TERM MODELS
THIS MORNING AND NICE CONSISTENCY RUN-TO-RUN. MAIN CONCERN IS
STRONG LOW THAT WILL BE DIPPING SOUTH AND PLUNGING THROUGH THE
GREAT BASIN TUESDAY AND WEDNESDAY. SNOW AND BLOWING SNOW IS
EXPECTED TUESDAY NIGHT THROUGH WEDNESDAY. WITH THE MOISTURE FLOW
ALOFT SOMEWHAT IN DOUBT...FOR NOW IT LOOKS LIKE WINTER WEATHER
ADVISORY CRITERIA AT LEAST.

TODAY AND TONIGHT. THE AXIS OF HIGH PRESSURE THAT GAVE US A NICE
EASTER IS NOW OVER UT/WY...LEAVING BEHIND A DAMPENED RIDGE THAT IS
ALLOWING SOME CLOUDS TO INFILTRATE NORTHERN NEVADA AS THE NEXT LOW
FEATURE APPROACHES. TEMPERATURES SHOULD GET A BOOST TODAY WITH THE
STRENGTHENING SW FLOW ALOFT. BREEZY WINDS WILL DEVELOP FOR MOST
AREAS TODAY WITH SOME LIGHT PRECIPITATION IN THE FORM OF RAIN WITH
AN ISOLATED TS POSSIBLE IN THE JARBIDGE MOUNTAINS. THERE IS A WEAK
THETA E RIDGE OVER NE NEVADA AND A WEAK LOW-LEVEL CONV/DIV
COUPLET AND THE CAPE IS PRETTY LOW. THERE MAY BE A FEW SHOWERS
DEVELOP OVER CENTRAL NEVADA AS WELL...HOWEVER DO NOT THINK TS IS
NEEDED ATTM FOR THIS AFTERNOON. THE LOWER LAYERS WILL CONTINUE TO
MOISTEN AS THE EVENING DRAGS ON BUT SNOW LEVELS WILL BE HIGH
ENOUGH FOR VALLEYS TO RECEIVE ONLY RAIN. 700MB TEMPS REMAIN
RELATIVELY HIGH ALL NIGHT MONDAY NIGHT SO ONLY THE HIGHEST PEAKS
WILL RECEIVE SNOW.

TUESDAY AND TUESDAY NIGHT. THE FRONT SHOULD BE ENTERING THE LKN
CWA BY EARLY TUESDAY MORNING AND PUSH THROUGH TO EASTERN NV BY
LATE AFTERNOON AS THE UPPER TROUGH DIPS SOUTH TO RE-CENTER NEAR
RENO NV. THIS POSITIONING WILL ALLOW MOISTURE FROM NORTHERN BAJA
TO GET PULLED UP INTO THE CIRCULATION. WINDS WILL BE INCREASING BY
MID-DAY AND WHILE THE MOISTURE CORE FLOWS INTO UT...NORTHEAST
NEVADA SHOULD GET SOME GOOD SHOWER ACTIVITY. TEMPERATURES AT
700MB PLUMMET TO -13C BY LATE TUESDAY AFTERNOON IN WESTERN
HUMBOLDT COUNTY. SNOW WILL QUICKLY DROP TO THE VALLEY FLOORS. IT
IS POSSIBLE FOR EASTERN NEVADA TO GET A QUICK 1-3 INCHES OF
SNOWFALL FROM THIS FRONTAL PASSAGE IF EITHER GFS OR NAM12 MODEL
QPF VERIFIES. THUNDERSTORMS COULD BREAK OUT IN CENTRAL NEVADA AS
THE FRONT MOVES THROUGH. WILL BE ADJUSTING TEMPERATURES ON
TUESDAY...TAKING INTO ACCOUNT CLOUD COVER AND AN EARLY MAXIMUM DUE
TO THE SPEED OF THE FRONTAL PASSAGE. SHOULD BE ALL SNOW BY TUESDAY
EVENING AND MODELS ARE INDICATING SUBSTANTIAL WRAP-AROUND MOISTURE
FOR NE NV. GFS/NAM QPF PROPOSALS ARE FOR 0.7-0.8 INCHES OF LIQUID
OVER EXTREME EASTERN ELKO COUNTY. SINCE CORE OF MOISTURE FLOW FOR
NOW WILL PLAY FOR POTENTIAL WINTER WEATHER ADVISORY AND KEEP
HAZARDOUS WEATHER OUTLOOK GOING IN THE MEANTIME.

WEDNESDAY. THE UPPER LOW WILL BE EXITING OVER UT WEDNESDAY AND
WRAP-AROUND SNOW SHOWERS WILL CONTINUE. IT IS POSSIBLE FOR A FEW
MORE INCHES OF SNOW ON WEDNESDAY BEFORE THE LOW MOVES FAR ENOUGH
AWAY...ALTHOUGH TEMPERATURES WILL START TO REBOUND. WILL NEED TO
ADJUST TEMPS DOWN A BIT FOR WEDNESDAY FROM CURRENT FORECAST WITH CLOUD
COVER AND COLD AIR IN PLACE.

.LONG TERM...WEDNESDAY NIGHT THROUGH SUNDAY. LATEST MODEL SUITE IN
GOOD AGREEMENT WITH DEEP VERTICALLY STACKED TROUGH MAINTAINING
CYCLONIC FLOW ACROSS THE CWA AS H3 110+ KT JET ROUNDS THE BASE OF
THE TROUGH OVER THE INTER-MOUNTAIN WEST THROUGH THURSDAY. WILL
CONTINUE TO FORECAST CHANCE POPS MAINLY OVER THE EASTERN PORTION OF
THE CWA /EASTERN ELKO AND WHITE PINE COUNTIES/ WEDNESDAY NIGHT AND
THEN SLOWLY DIMINISH POPS DURING THURSDAY. BOTH THE GFS/ECMWF MODEL
QPF FIELDS SUGGEST SEVERAL INCHES OF ADDITIONAL SNOWFALL OVER THE
HIGHER TERRAIN OF ELKO AND WHITE PINE COUNTIES ESPECIALLY WEDNESDAY
NIGHT.

AFOREMENTIONED H3 JET TRANSITIONS TO THE LEE SIDE OF THE UPPER
TROUGH AS IT MOVES INTO THE SOUTHERN/CENTRAL PLAINS RESULTING IN
GRADUAL WEAKENING OF THE UPPER TROUGH THROUGH THE CENTRAL ROCKIES
DURING FRIDAY. ALTHOUGH A DRY NORTHERLY FLOW WILL PREVAIL ACROSS THE
CWA...TEMPERATURES BEGIN TO WARM THROUGH THE COLUMN SUPPORTING
SURFACE MAX TEMPERATURES TO RANGE THROUGH THE 50S AND INTO THE LOWER
TO MID 60S FRIDAY.

THE 00Z ECMWF IS NOW SUPPORTING THE GFS/GFS ENS SOLUTION IN BUILDING
A STRONG UPPER LEVEL RIDGE FROM THE EASTERN PACIFIC INTO THE GREAT
BASIN DURING THE UPCOMING WEEKEND AND LASTING WELL INTO NEXT WEEK.
WITH H7 TEMPERATURES WARMING TO AOA 5 DEG C...MAX TEMPERATURES WILL
REACH AROUND 70 DEGREES IN MANY LOCATIONS SUNDAY WITH WIDESPREAD 70
DEGREE READINGS EXPECTED EARLY NEXT WEEK.
&&

.AVIATION...PATCHY MID/HIGH CLOUDS MOVING FROM NORTHWEST TO
SOUTHEAST ACROSS THE CWA ATTM. ALTHOUGH CLOUDS WILL THICKEN AS LOW
PRESSURE AND ASSOCIATED COLD FRONT DEVELOPS OVER THE GREAT
BASIN...VFR CONDITIONS ARE EXPECTED THROUGH TODAY. INSTABILITY
INCREASES AHEAD OF THIS SYSTEM LEADING TO ISOLATED -SHRA/-TSRA IN
NORTHEAST ELKO COUNTY ALONG THE IDAHO BORDER WHERE PATCHY MVFR CIGS
ARE POSSIBLE THIS AFTERNOON. AS PRECIPITATION BECOMES WIDESPREAD
CIGS WILL LOWER TO MVFR POSSIBLY IFR ESPECIALLY LATER TUESDAY.
&&

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