ALONG THE EAST SLOPES OF THE RUBY MOUNTAINS AND EAST HUMBOLDT
RANGE AND ADJACENT VALLEYS LATER FRIDAY MORNING AND AFTERNOON.
LOCAL MODEL SHOWS POTENTIAL FOR GUSTS TO 60 MPH SO HAVE ISSUED A
HIGH WIND WARNING FOR THAT AREA. ON FRIDAY BROAD CYCLONIC FLOW

THE WAY OF ACCUMULATION IS EXPECTED. SNOW SHOWERS WILL LINGER
ACROSS NERN NEVADA THROUGH SATURDAY BEFORE FINALLY ENDING BY
SUNDAY AS UPPER RIDGE BUILDS IN FROM THE WEST.

.LONG TERM...SUNDAY NIGHT THROUGH NEXT THURSDAY. A WEAK RIDGE IS
CENTERED OVER THE GREAT BASIN TO BEGIN THE LONG TERM PERIOD...WITH A
TROUGH APPROACHING THE OFFSHORE WATERS OF NORTHERN CA. AS THE TROUGH
CONTINUES TO SPREAD EAST TOWARD CA SUNDAY NIGHT...SOUTHWESTERLY FLOW
ALOFT WILL SPREAD OVER NORTHERN NEVADA AND LEAD TO A CHANCE OF
SHOWERS TO MAINLY THE MOUNTAINS OF HUMBOLDT AND ELKO COUNTIES.
ENERGY FROM THE APPROACHING TROUGH IS EXPECTED TO SPLIT MONDAY NIGHT
INTO TUESDAY AS THE SYSTEM MAKES ITS INLAND PUSH. MODELS ARE NOT IN
AGREEMENT AS TO THE SPLITTING OF THE SYSTEM. ECMWF MODEL TAKES MOST
OF THE ENERGY SOUTH THROUGH CA WHICH KEEPS THE CWA MOSTLY DRY. GFS
HOWEVER TAKES A LITTLE MORE OF THE ENERGY THROUGH CENTRAL AND
NORTHERN NEVADA...WITH SHOWERS OVER MUCH OF THE CWA MONDAY EVENING
THROUGH TUESDAY NIGHT ALONG WITH LIGHT SHOWERS LINGERING ACROSS THE
MOUNTAINS OF NORTHEASTERN NEVADA INTO WEDNESDAY. BOTH MODELS KEEP

FRIDAY. 00Z FRIDAY 700MB WINDS ACROSS CENTRAL NEVADA ARE SOUTHEAST

NORTHERN NEVADA. THE KICKER IS THE LOCATION OF THE SURFACE LOW.
TONIGHT THE LOW IS CENTERED ACROSS WEST-CENTRAL NEVADA. THE
RESULTING EASTERLY SURFACE GRADIENT IN COMBINATION WITH THE
SOUTHEASTERLY H7 WINDS WILL GENERATE MODERATELY STRONG EASTERLY
RIDGELINE WINDS...AND THE POTENTIAL FOR DOWNSLOPE WINDS ALONG
WESTERN SLOPES OF MOUNTAINS ACROSS NORTHERN NEVADA. LATER TONIGHT
INTO FRIDAY MORNING...THE SURFACE LOW DRIFTS NORTHEAST INTO SOUTHERN
IDAHO...AND THE H7 WINDS BECOME WESTERLY. THIS SHOULD LEAD TO
