NATIONAL WEATHER SERVICE ELKO NV
210 PM PDT WED MAY 27 2015

.SYNOPSIS...SHOWERS AND THUNDERSTORMS WILL CONTINUE ACROSS EASTERN
NEVADA INTO THE EARLY EVENING HOURS...BEFORE RAPIDLY DISSIPATING
TONIGHT. AREAS OF FOG ARE POSSIBLE LATE TONIGHT AND THURSDAY
MORNING. WARMER AND DRIER WEATHER IS EXPECTED FOR THE REMAINDER OF
THE WEEK AND FOR THE UPCOMING WEEKEND.

&&

.SHORT TERM...TONIGHT THROUGH FRIDAY.

SHOWERS AND THUNDERSTORMS NUMEROUS ACROSS EASTERN NEVADA THIS
AFTERNOON, AS ONE LAST SHORTWAVE ROTATES AROUND THE TROUGH BASE
ACROSS NEVADA. SHORTWAVE HAS INTERACTED WITH CAPE AS HIGH AS 1500
J/KG TO PRODUCE SEVERAL STRONG TO LOCALLY SEVERE THUNDERSTORMS.
TROUGH AXIS EXPECTED TO BE ALONG THE UT/NV LINE BY EARLY EVENING,
AND CONVECTION WILL QUICKLY WEAKEN BEHIND THIS DEPARTING FEATURE.
LOSS OF INSTABILITY AND SUBSIDENT NW FLOW BEHIND DEPARTING TROUGH
WILL END ALL PRECIPITATION QUICKLY TONIGHT. SOME CLEARING THROUGH
THURSDAY MORNING, AND WITH SOILS AND BOUNDARY LAYER VERY MOIST,
AND PATCHY FOG OBSERVED THIS MORNING, MENTIONED AREAS OF FOG LATE
TONIGHT AND THURSDAY MORNING IN THE GRIDS.

THURSDAY...MUCH DRIER PATTERN BEGINS TO TAKE CONTROL. BROAD RIDGE
OF HIGH PRESSURE BUILDS ALONG THE WEST COAST, WHILE TROUGH LIFTS
OUT THROUGH THE NORTHERN ROCKIES. AS SUCH, HEIGHTS WILL RISE
ACROSS NEVADA AND TEMPERATURES WILL WARM SEVERAL DEGREES. RESIDUAL
MOISTURE AND INSTABILITY WILL ALLOW FOR A FEW AFTERNOON
THUNDERSTORMS ACROSS WHITE PINE COUNTY AND EASTERN ELKO COUNTY,
MAINLY TIED TO THE HIGHER TERRAIN, BUT MUCH LESS COVERAGE COMPARED
TO PREVIOUS DAYS.

FRIDAY...HIGH PRESSURE CONTINUES TO AMPLIFY, WITH HEIGHTS RISING
OVER NEVADA, AND THE WARMING TREND CONTINUING. MANY VALLEYS WARM
TO THE UPPER 70S, WITH LOWER 80S AT WINNEMUCCA. THE ADDITIONAL
WARMTH WILL FUEL SOME INSTABILITY ACROSS CENTRAL NEVADA, WITH
ISOLATED AFTERNOON THUNDERSTORMS MAINLY ON THE HIGHER TERRAIN,
ALONG AND SOUTH OF U.S. HIGHWAY 50.
TURNER


.LONG TERM...FRIDAY NIGHT THROUGH NEXT WEDNESDAY. WEAK INSTABILITY
IN COMBINATION WITH LINGERING MOISTURE SHOULD BRING SOME MORE
ISOLATED SHOWERS AND THUNDERSTORMS TO MAINLY MOUNTAINOUS AREAS FROM
SOUTHERN LANDER COUNTY...NORTHEAST TO JACKPOT. TROUGH ENERGY
APPROACHING FROM THE WEST WILL LEAD TO SHOWER AND THUNDERSTORM
ACTIVITY ACROSS MOST OF NORTHERN NEVADA. HIGH TEMPERATURES CLIMB A
FEW DEGREES SATURDAY AND A COUPLE MORE ON SUNDAY WITH MOST VALLEY
LOCATIONS IN THE MID 80S. TROUGH ENERGY MOVES INLAND OVER NORTHERN
CALIFORNIA AND NEVADA BY MONDAY AFTERNOON COOLING HIGH TEMPERATURES
BY AROUND 10 DEGREES. THUNDERSTORM ACTIVITY CONTINUES ACROSS
NORTHERN NEVADA MONDAY...AND MAY EXPAND A LITTLE FURTHER SOUTH
TOWARD BUT NOT REACHING HIGHWAY 50 IN CENTRAL NEVADA. TROUGH ENERGY
IS EXPECTED TO BE CENTERED OVER THE PACIFIC NORTHWEST TUESDAY...WITH
MOST LINGERING THUNDERSTORM ACTIVITY CONFINED TO NORTHERN HUMBOLDT
AND ELKO COUNTIES.

&&

.AVIATION...THUNDERSTORM ACTIVITY WILL CONTINUE ACROSS MOST OF
EASTERN AND PORTIONS OF WESTERN NEVADA INTO EARLY THIS EVENING.
STORMS THAT SET UP OVER KELY AND KEKO ARE EXPECTED TO PRODUCE SMALL
HAIL AND POSSIBLY BRIEF MODERATE RAINS...ALONG WITH GUSTY WINDS. AT
KWMC...DRIER AND MORE STABLE AIR IS PUSHING IN FROM THE WEST WHICH
SHOULD PREVENT THUNDERSTORMS FROM DEVELOPING TODAY. AT KTPH...THERE
WILL BE A SLIGHT CHANCE OF THUNDERSTORM ACTIVITY TODAY. WITH THE
BETTER OF CHANCE OF THUNDERSTORM ACTIVITY AROUND KTPH BEING OVER THE
MOUNTAINS TO THE NORTH AND EAST OF THE AIRPORT...OUTFLOW WINDS MAY
BE THE ONLY IMPACT.  ON THURSDAY THE BEST CHANCE FOR SOME ISOLATED
THUNDERSTORM ACTIVITY WILL BE AT KELY.

&&

.LKN WATCHES/WARNINGS/ADVISORIES...
