MOST FLOOD DEATHS OCCUR IN AUTOMOBILES. NEVER DRIVE YOUR VEHICLE INTO
AREAS WHERE THE WATER COVERS THE ROADWAY. FLOOD WATERS ARE USUALLY
DEEPER THAN THEY APPEAR. JUST ONE FOOT OF FLOWING WATER IS POWERFUL
ENOUGH TO SWEEP VEHICLES OFF THE ROAD. WHEN ENCOUNTERING FLOODED
ROADS MAKE THE SMART CHOICE...TURN AROUND...DONT DROWN.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ELKO NV
341 PM PDT SAT AUG 9 2014

.SYNOPSIS...AN UPPER LEVEL LOW PRESSURE SYSTEM OFF THE CALIFORNIA
COAST WILL PUSH MOISTURE INTO NEVADA FROM THE SOUTH
THROUGH TUESDAY. THIS WILL CONTINUE THE UNSETTLED WEATHER WITH
DAILY AFTERNOON THUNDERSTORMS. THUNDERSTORM ACTIVITY WILL INCREASE
IN AREAL COVERAGE ON MONDAY...BEFORE PEAKING ON TUESDAY AS A LOW
PRESSURE SYSTEM SWINGS THROUGH THE REGION.

&&

.SHORT TERM...SATURDAY NIGHT THROUGH MONDAY. THERE IS A WELL
DEFINED CLOSED 500MB LOW CURRENTLY OFF THE CENTRAL CALI COAST. ALL
MODELS HAVE THIS FEATURE STALLING OUT TONIGHT JUST OFF THE COAST
OF CALIFORNIA. IN ADDITION THE 4-CORNERS HIGH BEGINS TO AMPLIFY TO
OUR EAST OVER THE NEXT 24HRS. THIS IS ALLOWING SOUTHERLY FLOW TO
DEVELOP ACROSS THE REGION IN ADDITION THE CLOSED LOW IS CLOSE
ENOUGH INFLUENCE THE AREA WITH SHORTWAVES. ONE IS TRAVELING
THROUGH NORTHERN NEVADA THIS AFTERNOON AND EVENING WHICH IS
HELPING TO ADD CONVECTION. A FEW STORMS WILL REMAIN STRONG INTO
THE EVENING HOURS...ALSO INCREASED POPS ACROSS HUMBOLDT COUNTY AS
MUCAPE REMAINS ABOVE 300 J/KG WITH NEGATIVE LI VALUES. THIS
INSTABILITY WILL ALLOW THE CHANCE FOR SOME SHOWERS THROUGH THE
NIGHT.

SUNDAY LOOKS TO BE ANOTHER ACTIVE DAY WITH CONVECTION CHANCES
SPREADING FURTHER SOUTH ONCE AGAIN AS MOISTURE FROM ARIZONA BEGINS
TO PUSH INTO SOUTHERN NEVADA. NAM12 IS SHOWING ANOTHER 500MB
SHORTWAVE PUSHING THROUGH THE CWA FROM SOUTH TO NORTH
TOMORROW...WITH 500-300MB LAPSE RATES AROUND 7.5 C/KM AGAIN. LOW
LEVELS WILL REMAIN RELATIVELY DRY...ESPECIALLY ACROSS CENTRAL
NEVADA...SO CONVECTIVE DOWN-BURST THREATS WILL CONTINUE.

MONDAY MOISTURE SURGE REALLY BEGINS TO INCREASE FROM ARIZONA AS
CLOSED 500MB LOW OFF THE CALI COAST REMAINS IN PLACE...BUT A MAJOR
SHORTWAVE TROUGH AND JET EXIT REGION WILL BE PUSHING INTO THE
STATE. DEPENDING ON THE TIMING OF THIS WAVE THE SEVERE
THUNDERSTORM THREAT WILL BEGIN TO INCREASE AS EFFECTIVE BULK SHEAR
VALUES INCREASE TO 30KTS ACROSS THE REGION.

.LONG TERM...MONDAY NIGHT THROUGH NEXT SATURDAY. UPPER LOW JUST OFF
THE CENTRAL CA COAST OPENS TO A TROUGH MONDAY NIGHT SETTING UP
SOUTH-SOUTHWESTERLY FLOW OVER THE CWA TUESDAY. EXPECT INCREASED
INSTABILITY AND SHEAR OVER MOST OF NORTHERN AND EASTERN NEVADA
TUESDAY WITH ELEVATED CHANCE OF SEVERE STORMS. DRIER AND MORE STABLE
OVER WEST-CENTRAL NEVADA. MODELS DISAGREE ON HOW TO HANDLE THE TROUGH
BEYOND TUESDAY...WITH THE ECMWF DROPPING AN UPPER LEVEL LOW IN FROM
THE NORTHWEST WHILE THE GFS HOLDS ONTO TROUGH SOLUTION...GRADUALLY
PUSHING THE SYSTEM THROUGH THE INTER-MOUNTAIN WEST THURSDAY AND
FRIDAY. PREVIOUS GFS AND ECMWF MODEL RUNS BOTH SUGGESTING
WEST-NORTHWESTERLY FLOW OVER THE GREAT BASIN NEXT WEEKEND. LATEST
RUNS SHOW MORE INCONSISTENCIES...WITH THE EC TRYING TO BRING IN YET
ANOTHER UPPER LEVEL LOW FROM THE NORTHWEST. INCREASED POPS ACROSS
MUCH OF THE AREA TUESDAY...KEEPING AT LEAST SOME MENTION OF SHOWERS
AND THUNDERSTORMS OVER NORTHERN AND EASTERN NEVADA THROUGH FRIDAY.
FOR NOW HELD OFF ON INTRODUCING TS FOR NEXT WEEKEND.

&&

.AVIATION...SHOWERS AND THUNDERSTORMS TO CONTINUE OVER MOST OF
NORTHERN AND CENTRAL NEVADA INTO THIS EVENING. DRIER AND MORE STABLE
ACROSS WEST-CENTRAL NEVADA HOWEVER...AND AS SUCH NO MENTION OF TS AT
KTPH. STORMS WILL DIMINISH THIS EVENING...THOUGH MAY LINGER FURTHER
INTO THE EVENING HOURS ACROSS EASTERN NEVADA. STORMS REDEVELOP
SUNDAY WITH BEST CHANCE FOR VCTS OVER EASTERN NEVADA...KELY AND
KEKO.

&&

.FIRE WEATHER...CONVECTION WILL CONTINUE ACROSS NORTHERN STRAIGHT
INTO TUESDAY...WITH THE CHANCE FOR WETTING RAINS EACH AFTERNOON.
AFTER A FEW DAYS OF DRYING OUT ACROSS CENTRAL NEVADA...MOISTURE
WILL BEGIN TO INCREASE ONCE AGAIN STARTING TOMORROW...BUT ANY
CONVECTION THAT DOES OCCUR ACROSS THE VALLEYS WILL BE DRY IN
NATURE TOMORROW SOUTH OF HIGHWAY 50. THIS WILL BE THE ONLY DAY OF
DRY LIGHTING AS PWAT VALUES INCREASE ABOVE .75" ACROSS THE ENTIRE
STATE ON MONDAY...WITH MODELS CONTINUING TO TREND WETTER WITH THE
SUB-TROPICAL SURGE OF MOISTURE FROM ARIZONA AHEAD OF THE CLOSED
LOW OFF THE CALIFORNIA COAST. DIDN'T OVERDUE LAL VALUES ON
MONDAY...DUE TO TIMING ISSUES AND THE POTENTIAL FOR MID-DECK
CLOUDS KEEPING DAYTIME HEATING LIMITED. TUESDAY CALIFORNIA UPPER
LEVEL DISTURBANCE PUSHES THROUGH THE STATE WITH NUMEROUS SHOWERS
AND SCATTERED STORMS EXPECTED. A DRYING TREND IS EXPECTED TO BEGIN
BY MIDWEEK. OVERALL LIMITED FIRE WEATHER THREATS.
