AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ELKO NV
314 AM PDT FRI AUG 7 2015

.SYNOPSIS...A PACIFIC STORM SYSTEM WILL MOVE ACROSS THE FORECAST
AREA TODAY...THROUGH EARLY SATURDAY. THIS WILL SET THE STAGE FOR
WIDESPREAD SHOWERS AND THUNDERSTORMS...SOME OF WHICH COULD BE
STRONG TO SEVERE IN CENTRAL NEVADA. TEMPERATURES WILL BE NEAR OR
SLIGHTLY BELOW NORMAL FOR THIS TIME OF YEAR.

&&

.SHORT TERM...A BUSY DAY IS ON TAP FOR CENTRAL AND NORTHERN
NEVADA. THE MODELS ARE IN GOOD AGREEMENT WITH THE PLACEMENT OF
THE 500MB LOW. THIS WILL QUICKLY TRAVERSE NORTHERN NEVADA THROUGH
SATURDAY.

STRONG UPPER-LEVEL FLOW IS RAPIDLY INCREASING THIS MORNING WITH
STRONG MOISTURE ADVECTION INTO THE AREA. MANY CENTRAL NV LOCATIONS
NOW HAVE DEW POINTS APPROACHING 50. THIS ADVECTION OF MOISTURE
WILL CONTINUE NORTHWARD THROUGH THE MORNING...BEFORE BEING SHUNTED
TO THE EAST THIS AFTERNOON. THERE ARE TWO MAIN CONCERNS FOR
TODAY...THE FLASH FLOOD AND SEVERE WEATHER POTENTIAL.

SPC UPGRADED THE AREA TO A SLIGHT RISK FOR SEVERE THUNDERSTORMS.
AGREE WITH THIS AS STRONG DYNAMICAL FORCING WILL COMBINE WITH
MODEST MOISTURE/INSTABILITY/SHEAR TO POSSIBLY ORGANIZE A SEVERE
WEATHER THREAT. GIVEN THE CAPE VALUES OF 500-1000 J/KG AND SHEAR
OF 35-55 KNOTS...A FEW TRANSIENT/MARGINAL SUPERCELLS CANNOT BE
RULED OUT. HOWEVER...THE MOST PROMINENT STORM MODE WILL BE
STRONG/SEVERE MULTICELLS. DAMAGING WIND APPEARS TO BE THE MAIN
THREAT...BUT A FEW ISOLATED HAIL EVENTS WILL BE POSSIBLE AS SOME
STORMS WILL HAVE ROTATING UPDRAFTS. CLOUD COVER HAS BEEN A
CONCERN...BUT IT LOOKS LIKE WE WILL SEE BREAKS IN THE CLOUDS THIS
MORNING. THIS SHOULD ALLOW FOR THE ATMOSPHERE TO QUICKLY
DESTABILIZE.

THERE IS ALSO A POTENTIAL FOR FLASH FLOODING GIVEN THE STORM BASED
INGREDIENTS. NOT CONFIDENT ENOUGH TO ISSUE A FLASH FLOOD
WATCH...BUT THE HIGHEST THREAT APPEARS TO BE IN NE NYE...WHITE
PINE...THE RUBY MTNS...SE/CENTRAL ELKO COUNTIES. STORM MOTIONS
WILL BE FAST...BUT MEAN FLOW PARALLEL TO TERRAIN FEATURES AND THE
CONTINUAL ADVECTION OF MOISTURE WILL ENHANCE THE TRAINING ASPECT
OF THUNDERSTORMS. ALSO CONVERGENCE APPEARS TO BE QUITE STRONG IN
CENTRAL NEVADA...FURTHER INCREASING THE THREAT. LOW LCLS AND AN
INCREASED DEPTH OF WARM CLOUD RAIN PROCESSES WILL ALSO EXIST. A
FEW LOCALIZED FLASH FLOOD ISSUES WILL BE POSSIBLE.

FRIDAY NIGHT AND SATURDAY....STORMS WILL LINGER LATE...POTENTIALLY
OVERNIGHT IN ELKO COUNTY. RESIDUAL MOISTURE AND WEAK DISTURBANCES
ON SATURDAY WILL ALLOW FOR SOME ISOLATED STORMS ACROSS NORTHERN
NEVADA.

.LONG TERM...SATURDAY NIGHT THROUGH NEXT THURSDAY. MODELS IN GOOD
AGREEMENT THROUGH MOST OF THE LONG TERM...SOME DIFFERENCES ARISE
BEGINNING WEDNESDAY AS GFS IS A BIT DEEPER AND FASTER WITH LOW
PRESSURE SYSTEM MOVING FROM THE PACIFIC. TEMPERATURES WILL BE NEAR
NORMAL THROUGH WEDNESDAY.

SATURDAY NIGHT THROUGH SUNDAY...RESIDUAL MOISTURE AND INSTABILITY
WILL ALLOW SOME CONVECTION TO THE DEVELOP MAINLY IN ELKO COUNTY...
BUT MAY EXTEND A BIT INTO EUREKA COUNTY.

MONDAY AND TUESDAY...500MB LOW MOVES SOUTH ALONG THE PACIFIC
NORTHWEST COAST TO NEAR NORTHERN CALIFORNIA BY TUESDAY. THIS WILL
PUT THE GREAT BASIN IN DRY SOUTHWESTERLY FLOW. PRESSURE GRADIENT
TIGHTENS UP A BIT ON TUESDAY WITH BREEZY WINDS MAINLY ACROSS CENTRAL
NEVADA WHICH COULD CAUSE SOME FIRE WEATHER CONCERNS.

WEDNESDAY AND THURSDAY...MODELS DIFFERENCES ARISE WITH GFS A BIT
DEEPER AND MORE PROGRESSIVE THAN OTHER MODELS...MOVING LOW ONSHORE
ON WEDNESDAY. MONSOON MOISTURE WILL SKIRT FAR EASTERN NEVADA WITH
INCREASING CLOUDS AND CHANCES OF THUNDERSTORMS...ONLY MADE SLIGHT
CHANGES TO POPS DUE TO LOWER FORECAST CONFIDENCE DUE TO MODELS
DIFFERENCES NOTED ABOVE. A DRY COLD FRONT EXPECTED TO MOVE ACROSS
THE GREAT BASIN THURSDAY WITH TEMPERATURES DROPPING TO BELOW
AVERAGE. WINDS WILL ALSO BE GUSTY ESPECIALLY ON WEDNESDAY AHEAD OF
THE COLD FRONT...THIS COULD CAUSE SOME FIRE WEATHER CONCERNS.

&&

.AVIATION...VARIABLE CLOUDS TODAY BUT VFR. SHOWERS AND THUNDERSTORMS
A GOOD BET AT ALL TERMINALS TODAY. 25% CHANCE OF TS NEAR
KWMC...OTHERWISE 40 TO 50 PERCENT CHANCE AT OTHER TAF SITES. SOME OF
THE THUNDERSTORMS COULD BE STRONG TO SEVERE WITH GUSTY WINDS AND
HAIL BEING THE MAIN THREATS ESPECIALLY NEAR KEKO AND KELY.

&&

.FIRE WEATHER...EXPECT WIDESPREAD SHOWERS AND THUNDERSTORMS TODAY.
FOR THE SEVERE/FLASH FLOOD THREAT...PLEASE REFER TO THE SHORT
TERM FORECAST DISCUSSION ABOVE. WITH EFFICIENT RAINERS...DO NOT EXPECT
ANY DRY THUNDERSTORM ISSUES. A FEW HYBRID STORMS WILL INITIALLY BE
POSSIBLE OR ALONG THE FRINGE IN HUMBOLDT...BUT SHOULD QUICKLY
TRANSITION TO ALL WET STORMS. ISOLATED STORMS LINGER INTO THE
WEEKEND...BUT A DRYING TREND WILL TAKE HOLD EARLY NEXT WEEK. LOW
RH AND GUSTY WINDS COULD BE A CONCERN LATER NEXT WEEK...BUT
CONFIDENCE IS LOW AT THIS TIME.

&&

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