MOVE ACROSS NEVADA TODAY AND TONIGHT BRINGING UNSETTLED WEATHER TO
THE GREAT BASIN. A RETURN TO DRIER AND WARMER CONDITIONS IS EXPECTED
BY MID-WEEK.
&&

.UPDATE...SHOWERS SETTING UP IN COUPLE BANDS ACROSS NORTHERN NEVADA
THIS MORNING. FRONT ATTM JUST EAST OF WINNEMUCCA. TS DEVELOPMENT
MAINLY BEHIND FROPA. QUITE A FEW POSITIVE STRIKES. NOT MANY
BREAKS IN THE CLOUDS OUT AHEAD OF THE FRONT ATTM. BOUNDARY PRETTY
WELL ALIGNED THE WAY MODELS HAVES SUGGESTED THE LAST FEW DAYS.
FORECAST TO SHIFT SLOWLY SE AS DAY WEARS ON...WITH RR OF JET. UPDATED
THIS MORNING MAINLY TO ADD FLOOD WARNING FOR URBAN...ELY...AND SMALL
STREAMS OVER SOUTHERN LANDER AND EUREKA COUNTIES. FLOOD WATCH WILL
REMAIN FOR NORTHERN NYE COUNTY ATTM THROUGH 9 PM TONIGHT WHEN WE CAN
GET THIS SYSTEM THROUGH THE AREA.
&&

.PREV DISCUSSION...TROF AXIS ALONG WEST COAST SWINGS INTO
CENTRAL NEVADA BY 00Z TODAY. FIRST VORT MAX AHEAD OF UPPER LOW MOVING
ACROSS CWA EARLY THIS MORNING BRINGING SHOWERS TO NORTHERN AND WEST
CENTRAL NV ATTM. GOOD 300/700MB DIVERGENT/CONVERGENT COUPLET
ASSOCIATED WITH 120 KNOT JET ON BACKSIDE OF UPPER LOW DEVELOPS OVER
CWA TODAY SO HAVE BUMPED POPS TO CATEGORICAL. HAVE INCREASED EVENING
POPS OVER EASTERN CWA WITH TROF AXIS PUSHING INTO UTAH OVERNIGHT.
STRONG VORT LOBE OVER WHITE PINE COUNTY TONIGHT PRODUCING GOOD QPF
AMOUNTS. 35-40 KNOT 700 MB FLOW SHOULD BRING THE USUAL WINDY
CONDITIONS TO WENDOVER SO WILL ISSUE A WIND ADVISORY FOR NVZ033.
WINDS DO INCREASE OVER WHITE PINE COUNTY THIS AFTERNOON...BUT BELIEVE
WINDS WILL BE BELOW CRITERIA DUE TO GOOD CLOUD COVER AND PCPN. WINDS
OVER NVZ035 EXPECTED TO BECOME NORTHWEST AND DECREASE AFTER FRONTAL
PASSAGE EARLY THIS EVENING. SNOW LEVELS DO NOT APPEAR TO BE A PROBLEM
AND WILL NOT DROP SIGNIFICANTLY UNTIL MOISTURE EXITS ON TUESDAY. THIS
COULD BE MORE OF A CONCERN FOR RIVER FLOWS...ENHANCING THE SNOWMELT
RATE. BUT AT SAME TIME WILL CONTINUE FLOOD WATCH FOR CENTRAL NV...BUT
THINK ANY FLOODING WILL NOT OCCUR UNTIL AFTER 3 TO 5 DAYS OF GOOD
WARMING WITH TEMPERATURES IN AT LEAST IN THE 70S OR STRONG WAA.
HARMER

.LONG TERM...DRY AND WARM...GFS CONTINUES WITH MORE AMPLIFIED
SLIGHTLY SLOWER NRN SOLUTION WITH THUR/FRI U/L TROUGH OVER THE
WESTERN US. THIS SYSTEM WILL BE MAINLY A PACIFIC NW EVENT...ALTHOUGH
WITH S/WV ENERGY CLIPPING NRN NV AND RIGHT REAR U/L JET...KEPT A
CHANCE OF TRWS THUR AFT. ALSO...GFS IS SHOWING SOME INSTABILITY AND
SURFACE TROUGH OVER THE GREAT BASIN AT THIS TIME. PROVIDED
MOISTURE...SHOULD SEE AT LEAST SOME CONVECTION NORTH OF I80. ONE
CAVEAT WITHSTANDING...ECMWF AND UKMET ARE MUCH LESS PRONOUNCED IN
THE DEVELOPMENT OF U/L TROUGH AND KEEP ENERGY OVER THE PAC NW.

ADJMRF BRINGS SURFACE TEMPERATURES TO AROUND 90 DEGREES ACROSS SRN
ZONES BY THURSDAY...THINK THIS IS A BIT OVERDONE BUT IF GFS 7H TEMPS
OF 12 TO 14 C COME TO FRUITION...MID 80S ARE CERTAINLY A
POSSIBILITY. PRE-FRONTAL SW WINDS ON THURSDAY LOOK TO BE DECENT...THE
COMBINATION OF WIND AND WARM TEMPS WILL EXPEDITE MELT OF SNOW PACK.
WILL HAVE TO CONTINUE TO MONITOR POSSIBLE FLOODING IN THE SRN
ZONES.

FOR THE WEEKEND INTO NEXT WEEK...EXTENDED MODEL CONSENSUS IS
FOR THE ESTABLISHMENT OF A RIDGE OVER THE GREAT BASIN. THIS WOULD
LEND TO AN EXTENDED PERIOD OF ABOVE NORMAL TEMPS AND SUNNY SKIES
THROUGHOUT NV...MORE POTENTIAL FOR A QUICK MELT OF MOUNTAIN
SNOWPACK. LIEBL
