...A FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 615 PM PDT FOR WEST
CENTRAL ELKO COUNTY...

AT 440 PM PDT...NATIONAL WEATHER SERVICE DOPPLER RADAR CONTINUED TO 
INDICATE AN AREA OF MODERATE TO HEAVY SHOWERS AND THUNDERSTORMS OVER 
THE WARNED AREA....WHICH COULD PRODUCE FLASH FLOODING. ADDITIONAL 
RAINFALL UP TO ONE QUARTER OF AN INCH WILL BE POSSIBLE. 

LOCATIONS IN THE WARNING INCLUDE BUT ARE NOT LIMITED TO 
MIDAS...MIDAS ROAD BETWEEN MIDAS AND 10 MILES SOUTHWEST OF 
TUSCARORA. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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.

IN HILLY TERRAIN THERE ARE HUNDREDS OF LOW WATER CROSSINGS WHICH ARE
POTENTIALLY DANGEROUS IN HEAVY RAIN. DO NOT ATTEMPT TO TRAVEL ACROSS
FLOODED ROADS. FIND ALTERNATE ROUTES. IT TAKES ONLY A FEW INCHES OF
SWIFTLY FLOWING WATER TO CARRY VEHICLES AWAY.

TO REPORT FLOODING...HAVE THE NEAREST LAW ENFORCEMENT AGENCY RELAY
YOUR REPORT TO THE NATIONAL WEATHER SERVICE FORECAST OFFICE IN ELKO.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ELKO NV
210 PM PDT THU SEP 12 2013

.SYNOPSIS...A MOIST LOW PRESSURE SYSTEM WILL SLOWLY DRIFT ACROSS
NORTHEAST NEVADA THROUGH FRIDAY...PRODUCING WIDESPREAD SHOWERS AND
THUNDERSTORMS. AREAS OF LOCALLY HEAVY RAIN ARE EXPECTED. SCATTERED
THUNDERSTORMS WILL PERSIST ACROSS EASTERN NEVADA ON SATURDAY. DRY
WEATHER RETURNS TO NEVADA SUNDAY THROUGH NEXT WEEK.

&&

.SHORT TERM...TONIGHT THROUGH SATURDAY.

MOIST LOW PRESSURE SYSTEM SPINNING DIRECTLY OVER NEVADA THIS
AFTERNOON. NUMEROUS SHOWERS AND THUNDERSTORMS ON RADAR, ROTATING
COUNTERCLOCKWISE AROUND A CIRCULATION CENTER BETWEEN ELKO AND
EUREKA. MOISTURE QUALITY CONTINUES TO BE VERY HIGH, WITH
PRECIPITABLE WATER NEAR ONE INCH ACROSS ALL OF NEVADA. ALL SHOWERS
AND THUNDERSTORMS WILL PRODUCE LOCALLY VERY HEAVY RAIN THROUGH
8 PM, WITH RAINFALL RATES OF 1-2 INCHES PER HOUR FROM THE
STRONGEST STORMS. STORM MOTION IS SLOW AND OF COURSE VARIED AND
ERRATIC AMID THE BROAD CIRCULATION. FLASH FLOOD WATCH WILL
CONTINUE, WITH LOCALLY HEAVY RAIN EXPECTED ACROSS ALL ZONES.
EXPECT SHOWER AND THUNDERSTORM COVERAGE TO BEGIN DECREASING AROUND
SUNSET /7 PM/ WITH THE LOSS OF HEATING. JUST LIKE LAST NIGHT,
EXPECT SCATTERED SHOWERS AND ISOLATED THUNDER TO PERSIST
OVERNIGHT. VERY WARM AGAIN TONIGHT UNDER THE CLOUDS, WITH NEAR
RECORD WARM LOW TEMPERATURES IN THE 50S.

FRIDAY...MOIST LOW PRESSURE SITS AND SPINS OVER ELKO COUNTY THE
ENTIRE DAY. ATMOSPHERE IS STILL VERY MOIST WITH PW NEAR ONE INCH.
NAM AND GFS BOTH FORECAST ENOUGH INSTABILITY FOR CONVECTIVE
TEMPERATURES IN THE LOW TO MID 70S TO BE REACHED, AND EXPECT
SHOWERS AND THUNDERSTORMS TO BECOME NUMEROUS ONCE AGAIN BY FRIDAY
AFTERNOON. RAIN AND THUNDERSTORMS WILL BE MOST NUMEROUS ACROSS
ELKO COUNTY. LAST SHIFT EXTENDED THE FLASH FLOOD WATCH THROUGH
FRIDAY EVENING, WHICH IS CLEARLY WARRANTED. WILL ALSO ADD NORTHERN
ELKO COUNTY /ZONE 031/ WHICH IS RECEIVING MANY THUNDERSTORMS
CURRENTLY, AND IS FORECASTED TO RECEIVE SOME OF THE HEAVIEST RAIN
ON FRIDAY, CLOSEST TO THE LOW'S TRACK. STORM MOTION WILL CHANGE ON
FRIDAY, WITH MOST STORMS SHOWING A SLOW SE DRIFT BY FRIDAY AFTERNOON.

SATURDAY...PERSISTENT MOIST LOW PRESSURE SYSTEM FINALLY WEAKENS
AND EXITS NEVADA. DRY WEATHER RETURNS TO THE WESTERN 1/2 OF THE
CWA, BUT MOISTURE AND INSTABILITY REMAIN SUFFICIENT FOR ONE MORE
CROP OF SCATTERED THUNDERSTORMS, MAINLY ACROSS ELKO AND WHITE PINE
COUNTIES. INCREASED THUNDERSTORM COVERAGE IN THE GRIDS, BUT
COVERAGE WILL BE MUCH LESS COMPARED TO THAT SEEN TODAY AND FRIDAY.
AFTERNOON TEMPERATURES SATURDAY WARM 2-4 DEGREES OVER FRIDAY'S
READINGS, AS DRIER AIR BEGINS TO WORK INTO NEVADA.  TURNER

.LONG TERM...SATURDAY NIGHT THROUGH NEXT THURSDAY. MAIN THEME OF THE
LONG TERM...AS COMPARED TO THE SHORT TERM...IS DRY. UPPER LOW WHICH
BROUGHT THE MONSOON MOISTURE WILL BE DEPARTING NORTHEASTWARD AT THE
BEGINNING OF THE PERIOD WITH A MUCH DRIER TROUGH FROM THE PACIFIC
MOVING IN SUNDAY NIGHT. WITH A UPPER LOW SITTING OVER THE PAC NW
EARLY NEXT WEEK DRY WEATHER SHOULD GENERALLY PREVAIL...THOUGH IN
NORTHEASTERN NEVADA MOISTURE MAY TAKE A LITTLE WHILE TO COMPLETELY
GET SCOURED OUT.

THERE IS NOW SOME DISAGREEMENT REGARDING THE POSSIBLE DEEPER AND
COLDER TROUGH DURING THE MIDDLE OF NEXT WEEK. GFS STILL HAS IT...BUT
THE ECMWF HAS MOVED AWAY FROM IT. THEREFORE DID NOT ALTER FORECAST
TOO MUCH THIS FAR OUT.  RCM

&&

.AVIATION...MAINLY VFR CIGS AND VIS NEXT 24 HOURS...OCCASIONALLY
LOWER IN HEAVY THUNDERSTORMS. T-STORMS ARE THE BIGGEST CONCERN...AND
WILL BE MOST NUMEROUS IN THE AFTERNOON/EVENING HOURS BOTH TODAY AND
FRIDAY.  RCM

&&

.FIRE WEATHER...NUMEROUS RAIN SHOWERS AND THUNDERSTORMS THROUGH
FRIDAY WITH LAL'S OF 4-5 AT TIMES. ANY LIGHTNING IGNITIONS WILL
HAVE GREAT DIFFICULTY SPREADING GIVEN WETTING RAINS, HIGH RELATIVE
HUMIDITY, AND GREEN/GROWING FUELS. THUNDERSTORMS WILL BE CONFINED
TO ELKO AND WHITE PINE COUNTY ON SATURDAY, BEFORE DRY WEATHER
RETURNS TO NEVADA SUNDAY AND THROUGH NEXT WEEK.  TURNER
