AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE ELKO NV
625 PM PDT TUE AUG 4 2015

.SYNOPSIS...A WEAKENING STORM SYSTEM FROM THE PACIFIC WILL SPREAD
SHOWERS AND THUNDERSTORMS ACROSS FAR NORTHERN NEVADA TONIGHT, AND
STRONG GUSTY WEST WINDS ON WEDNESDAY. TEMPERATURES WARM SEVERAL
DEGREES ON THURSDAY. THE NEXT LOW PRESSURE SYSTEM FROM THE PACIFIC
WILL SPREAD SHOWERS AND THUNDERSTORMS ACROSS NEVADA ON FRIDAY.
&&

.UPDATE...BASED ON CURRENT TRENDS AND LATEST HRRR AND RAP MODELS
UPDATED FORECASTS TO REDUCE THUNDERSTORM COVERAGE TO ISOLATED THIS
EVENING WITH ANY THUNDERSTORMS CONFINED TO AREAS NORTH OF
INTERSTATE 80. SHOWERS AND THUNDERSTORMS COVERAGE WILL INCREASE
AFTER MIDNIGHT AS SHORT WAVE MOVES INTO NORTHERN NEVADA, BUT WILL
STILL BE MOSTLY NORTH OF INTERSTATE 80. CEC

.PREV DISCUSSION... /ISSUED AT 200 PM /

SYNOPSIS...A WEAKENING STORM SYSTEM FROM THE PACIFIC WILL SPREAD
SHOWERS AND THUNDERSTORMS ACROSS NORTHERN NEVADA TONIGHT...AND
STRONG GUSTY WEST WINDS ON WEDNESDAY. TEMPERATURES WARM SEVERAL
DEGREES ON THURSDAY. THE NEXT LOW PRESSURE SYSTEM FROM THE PACIFIC
WILL SPREAD SHOWERS AND THUNDERSTORMS ACROSS NEVADA ON FRIDAY.

SHORT TERM...TONIGHT THROUGH THURSDAY.

SHORTWAVE AND WEAK CLOSED LOW ARRIVING ON THE CALIFORNIA COAST
THIS AFTERNOON, AND WILL SPREAD MID/HIGH CLOUDS ACROSS NEVADA
THROUGH THIS EVENING. AHEAD OF THIS, INSTABILITY IS FOCUSED MAINLY
ACROSS ELKO COUNTY THIS AFTERNOON, AND CUMULUS FIELD IS EXPANDING
ON VISIBLE SATELLITE IMAGERY. SOME STRONGER STORMS ARE POSSIBLE
ACROSS EASTERN ELKO COUNTY THROUGH SUNSET, WHERE CAPE IS NEAR
1000 J/KG AND EFFECTIVE BULK SHEAR IS 30-35 KTS.

LATER TONIGHT...VORT MAX ROTATES TO JUST WEST OF GERLACH BY 5 AM.
LIFT AHEAD OF THIS FEATURE WILL BE SUBSTANTIAL, AND COMBINE WITH
NOCTURAL MID-LEVEL INSTABILITY, TO PRODUCE SCATTERED SHOWERS AND
THUNDERSTORMS. EXPECT ACTIVITY TO FOCUS ACROSS NORTHERN HUMBOLDT
AND NW ELKO COUNTIES. NOCTURNAL CLOUD-TO-GROUND LIGHTNING STRIKES
ALWAYS HARD TO COME BY IN NEVADA, BUT SHORTWAVE AND JET SUPPORT
MAY ALLOW FOR SOME ACROSS NW NEVADA TONIGHT. CLOUDS, MIXING AND
INCREASING MOISTURE WILL KEEP LOW TEMPERATURES WEDNESDAY MORNING
QUITE MILD, IN THE UPPER 50S AND LOWER 60S.

WEDNESDAY...WINDY. SHORTWAVE WEAKENS AND CROSSES NORTHERN NEVADA
DURING THE DAY, WITH WESTERLY 700 MB FLOW INCREASING TO NEAR
25 KTS. SW/W WINDS WILL AVERAGE 15-25 MPH WITH GUSTS NEAR 35 MPH.
MUCH DRIER AIR ADVECTS INTO MUCH OF CENTRAL NEVADA, SO MOST
LOCATIONS WILL BE DRY. LINGERING MOISTURE/INSTABILITY WILL
SUPPORT ISOLATED THUNDERSTORM DEVELOPMENT WEDNESDAY AFTERNOON
ACROSS ELKO COUNTY, WITH THE BEST COVERAGE ACROSS NE ELKO COUNTY.
PASSING SHORTWAVE WILL COOL TEMPERATURES SEVERAL DEGREES, WITH
AFTERNOON HIGHS IN THE VALLEYS SEVERAL DEGREES BELOW NORMAL IN THE
80S.

WEDNESDAY NIGHT...CLEARING AND COOLER. RADIATIONAL COOLING
RETURNS, WITH MANY LOCALES FALLING INTO THE 40S THURSDAY MORNING.

THURSDAY...WARMER. HIGH PRESSURE RIDGING STRENGTHENS ONCE AGAIN,
AHEAD OF NEXT LOW PRESSURE IN THE EASTERN PACIFIC. MANY LOCATIONS
ABOUT 5 DEGREES WARMER THAN WEDNESDAY. MARGINAL MOISTURE RETURNS
THURSDAY AFTERNOON BENEATH THE BUILDING RIDGE AXIS, BUT GFS KEEPS
PW RESTRICTED TO NEAR 1/2 INCH, AND INSTABILITY FROM NAM IS
ANEMIC, WITH LIFTED INDEX STRUGGLING TO GET BELOW ZERO. AS SUCH,
ONLY ALLOWED FOR AFTERNOON CUMULUS BUILDUPS THURSDAY AFTERNOON,
AND KEPT ALL ZONES DRY. TURNER

LONG TERM...THURSDAY NIGHT THROUGH NEXT TUESDAY. MODELS IN VERY
GOOD AGREEMENT THROUGH THE LONG TERM.

THURSDAY NIGHT AND FRIDAY...AN 500MB LOW APPROACHING THE CENTRAL
CALIFORNIA COAST WILL PUT THE GREAT BASIN IN A FAVORABLE AREA FOR
SHOWERS AND THUNDERSTORMS. UPPER LEVEL DIFFLUENCE WILL COMBINE WITH
80-90 KNOT JET MAX AND SUFFICIENT MOISTURE AND CAPE FOR STRONG TO
POSSIBLY SEVERE THUNDERSTORMS ACROSS THE AREA...HOWEVER CONFIDENCE
IS NOT HIGH YET IN THIS SCENARIO. THURSDAY NIGHT AND FRIDAY MORNING
MODELS DEPICT CLOUDS AND PRECIPITATION DEVELOPING IN CENTRAL NEVADA
AND MOVING NORTHWARD THROUGH FRIDAY MORNING. THIS COULD PUT A DAMPER
ON THE AFTERNOON CONVECTION IF CONVECTIVE TEMPERATURES ARE NOT
REALIZED. IF ENOUGH HEATING CAN OCCUR MODELS INDICATE CAPE OF 500-
1000 J/KG AND PW'S FROM .75 TO CLOSE TO AN INCH IN SOME LOCATIONS.
STORM MOTIONS SHOULD BE SUFFICIENT TO KEEP FLASH FLOODING ISSUES TO
A MINIMUM. MAIN THREAT WILL BE GUSTY OUTFLOW WINDS AND HAIL.

FRIDAY NIGHT AND SATURDAY...UPPER LOW WILL OPEN UP AND MOVE
NORTHEAST THROUGH NORTHERN NEVADA SATURDAY MORNING WITH SHOWERS AND
ISOLATED THUNDERSTORMS POSSIBLE FRIDAY NIGHT THROUGH SATURDAY
MORNING DUE TO STRONG DYNAMICS. GFS IS STILL JUST A BIT FASTER
MOVING THE LOW/TROUGH EAST ON SATURDAY. THUNDERSTORMS EXPECTED
MAINLY NORTH OF I-80 ON SATURDAY AFTERNOON/EVENING AS PW'S WILL HANG
AROUND .75"...BUT MUCH DRIER SOUTH OF I-80.

SUNDAY THROUGH TUESDAY...DRY SOUTHWESTERLY FLOW WILL DOMINATE WITH
HIGH PRESSURE NEAR TEXAS AND LOW PRESSURE OFF THE COAST OF THE
PACIFIC NORTHWEST. MODELS HINT AT ANOTHER PUSH OF MONSOON MOISTURE
TO EAST CENTRAL NEVADA BY NEXT TUESDAY AND WEDNESDAY. RLC

AVIATION...INCREASING HIGH CLOUDS AS A UPPER LEVEL DISTURBANCE
MOVES ACROSS NORTHERN NEVADA. BEST BET FOR TS WILL BE AT KEKO
THROUGH THIS EVENING, WHERE CHANCES ARE ABOUT 30-40%...OTHERWISE
A 10-15 PERCENT CHANCE FOR KWMC BUT EXPECT MOST -TSRA TO STAY EAST
OF KWMC. GUSTY OUTFLOW WINDS AND SMALL HAIL POSSIBLE WITH THE
THUNDERSTORMS NEAR KEKO. DRY AND STABLE AT KELY AND KTPH WITH
BREEZY AFTERNOON WINDS. RLC

FIRE WEATHER...SCATTERED CONVECTION OVER ELKO COUNTY INTO THIS
EVENING BEFORE DIMINISHING AFTER SUNSET. SHORTWAVE ARRIVING ON THE
CALIFORNIA COAST THIS AFTERNOON WILL ARRIVE IN NW NEVADA
OVERNIGHT TONIGHT. AHEAD OF THIS INCOMING DISTURBANCE, SHOWERS AND
ISOLATED TO SCATTERED NOCTURNAL THUNDERSTORMS ARE POSSIBLE
TONIGHT, ACROSS NORTHERN PORTIONS OF FWZ 467, 468 AND 469. AFTER
COORDINATION WITH THE GACC, CONCERN IS PRESENT FOR NEW LIGHTNING
IGNITIONS ACROSS THESE AREAS OVERNIGHT, AS PW WILL BE LIMITED
ALONG WITH QUICK STORM MOTIONS. KEPT LAL OF 3-4 FOR THESE AREAS,
BUT THE POTENTIAL FOR AT LEAST ISOLATED DRY LIGHTNING STRIKES IS
THERE ACROSS NW NEVADA TONIGHT.

WEDNESDAY...WEAKENING SHORTWAVE CROSSES NORTHERN NEVADA, PRODUCING
STRONG GUSTY W/SW WINDS. WINDS WILL AVERAGE 15-25 MPH FOR MOST
FWZ, WITH GUSTS OF 30-40 MPH. ALTHOUGH WIND GUSTS ARE EXPECTED TO
APPROACH/EXCEED CRITICAL THRESHOLDS ACROSS MUCH OF ELKO, EUREKA
AND WHITE PINE COUNTIES, MIN RH WILL REMAIN JUST ABOVE 15% FOR
MOST OF THESE ZONES. CAUTION IS ADVISED AS WEST WINDS INCREASE ON
WEDNESDAY. ANY CONVECTION WEDNESDAY WILL BE CONFINED TO ELKO
COUNTY AND LIMITED IN COVERAGE.

THURSDAY...WARMER, DRY AND LESS WIND AS HIGH PRESSURE REBUILDS
OVER NEVADA.

FRIDAY...NEXT PACIFIC LOW ARRIVES, SPREADING THUNDERSTORMS ACROSS
NEVADA ONCE AGAIN. TURNER
