...A FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 730 PM PDT FOR SOUTH
CENTRAL WASHOE COUNTY...

AT 515 PM PDT...TRAINED WEATHER SPOTTERS REPORTED FLASH FLOODING FROM
A THUNDERSTORM LOCATED NEAR STEAD...5 MILES NORTH OF RENO.

SOME LOCATIONS AFFECTED INCLUDE...RENO...SPANISH SPRINGS...SPARKS AND
STEAD.

THE MAIN THUNDERSTORM HAS PUSHED OUT OF THE AREA WITH ONLY LIGHT RAIN 
CURRENTLY OVER THE NORTH VALLEYS OF RENO. ALTHOUGH THE STORM HAS MOVED 
OUT OF THE AREA IT LEFT OVER AN INCH OF RAINFALL IN LESS THAN ONE HOUR
IN THE STEAD AREA.

EXCESSIVE RUNOFF FROM HEAVY RAINFALL HAS CAUSED SOME FLOODING OF SMALL
CREEKS AND STREAMS...URBAN AREAS...HIGHWAYS...STREETS AND UNDERPASSES
AS WELL AS OTHER DRAINAGE AREAS AND LOW LYING SPOTS. 

HEAVY RAINFALL HAS PROMPTED LOCAL AUTHORITIES TO CLOSE SOME ROADS IN THE 
STEAD AREA. DO NOT ATTEMPT TO DRIVE YOUR VEHICLE ON FLOODED ROADS OR 
PAST BARRICADES. FLOOD WATERS ARE USUALLY DEEPER THAN THEY APPEAR. JUST 
A FEW INCHES OF FAST FLOWING WATER IS POWERFUL ENOUGH TO SWEEP VEHICLES 
OFF THE ROAD. 

TO REPORT FLOODING...BE SURE YOU ARE IN A SAFE PLACE FIRST. THEN
CONTACT THE NATIONAL WEATHER SERVICE IN RENO AT 775-673-8100. YOUR
REPORT MAY SAVE LIVES

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
318 PM PDT MON JUL 14 2008

.SHORT TERM...
SCATTERED...VERY SLOW MOVING SHOWERS AND THUNDERSTORMS HAVE DEVELOPED
NEAR THE SIERRA CREST SOUTH OF LAKE TAHOE...WITH ISOLATED CONVECTION
ELSEWHERE. THE CONCERN WITH STORMS SOUTH OF TAHOE IS HEAVY RAIN
WITH SLOW MOVEMENT AND RADAR STORM PRECIP ESTIMATES OF 1 TO 1.5 INCH
INDICATED THROUGH 3 PM. THE CONCERN FOR STORMS ELSEWHERE...ESPECIALLY
OVER NORTHWEST LASSEN COUNTY (NORTH OF EAGLE LAKE)...IS OUTFLOW WINDS
COMBINED WITH ISOLATED LIGHTNING STRIKES. THE RAWS AT ASH VALLEY
OVER FAR NORTHERN LASSEN COUNTY HAD A TEMPERATURE/DEWPOINT SPREAD
OF 62 DEGREES AT 2 PM...MORE THAN SUFFICIENT TO DROP SOME VERY
GUSTY WINDS WITH THUNDERSTORMS.

CONVECTIVE ACTIVITY WILL BE WANING AFTER THIS EVENING AS SOUTHWEST
FLOW ALOFT INCREASES WITH ENERGY MOVING INTO THE NORTHWEST STATES.
THE INCREASED SOUTHWEST FLOW ALOFT IN SUMMERTIME MEANS DRIER AND
MORE STABLE ATMOSPHERIC CONDITIONS...WHICH WILL CONTINUE THROUGH
AT LEAST THURSDAY. THE SLIGHT CHANCE OF THUNDERSTORMS WILL BE
CONFINED TO SOUTH OF A BRIDGEPORT TO WALKER LAKE LINE TUESDAY
AFTERNOON AND EVENING. HOWEVER...WHILE THUNDERSTORMS ACTIVITY WILL
BE WANING...STRONGER WESTERLY FLOW IN THE AFTERNOON AND EVENING
WILL LIKELY THROW MORE HAZE AND SMOKE OUR WAY THROUGH LATE WEEK.
SORRY FOLKS...BUT UNTIL THE NORTHERN CALIFORNIA FIRES ARE WELL IN
HAND THERE WILL BE AN AMPLE SUPPLY OF SMOKE TO SEND OUR WAY.

.LONG TERM...FRIDAY THROUGH MONDAY...
LITTLE CHANGE WAS MADE TO EXTENDED FORECAST WHICH WILL KEEP TEMPS
ABOVE NORMAL THRU EARLY NEXT WEEK WITH SOME VALLEYS IN W-CNTRL NV
TOPPING 100 DEGREES. RIDGE OVER THE FOUR CORNERS REGION AND ERN
GREAT BASIN IS EXPECTED TO REMAIN NEARLY STATIONARY THRU THE WEEKEND
AND MAY DRIFT A BIT EAST AS NEXT TROF OR UPPER LOW APPROACHES THE
WEST COAST. OVERALL MODEL GUIDANCE HAS NOT BEEN VERY CONSISTENT ON
STRENGTH OF RIDGE AND WHERE NEXT UPSTREAM TROF WILL TRACK...BUT
WITHOUT ANY MAJOR JET ENERGY THE RIDGE IS MORE LIKELY TO WIN OUT AND
DELAY THE ARRIVAL OF THE NEXT TROF OR CLOSED LOW. THEREFORE NO TSTMS
WERE ADDED AT THIS TIME BUT MONDAY MAY BEAR WATCHING FOR POSSIBLE
CONVECTION...ESPECIALLY IF THE ECMWF SOLUTION OF A CLOSER APPROACH
OF THE LOW INTO NRN CA VERIFIES. MJD
&&

.AVIATION...
SMOKE AND HAZE CONDITIONS HAVE IMPROVED SOMEWHAT TODAY WITH VSBY
CURRENTLY AT OR ABOVE 6 SM. HOWEVER...INCREASED WEST WINDS LATER
TODAY AND UNSTABLE CONDS WILL RAISE THE POSSIBILITY OF NEW SMOKE
PLUMES CARRIED IN FROM THE ACTIVE FIRES NEAR BLUE CANYON AND
BUTTE/PLUMAS/TEHAMA COUNTIES IN NERN CA. RIDGE LEVEL AND 700 MB
WINDS EXPECTED TO BECOME WEST BY THIS EVENING...WHICH WILL LIKELY
PRODUCE VSBY THIS EVENING AND LATER TONIGHT SOMEWHAT LOWER THAN
YESTERDAY. WILL MENTION PREDOMINANT VSBY 5-6SM AFTER 02Z FOR THE
KRNO-KTVL-KTRK SITES. ONE OF MORE OF THESE SITES MAY SEE VSBY DROP
TO 3 OR 4 MILES AT TIMES LATE TONIGHT THRU TUES MORNING. ONE
UNCERTAINTY IS WHETHER OUTFLOW WINDS AND RAIN FROM SHOWERS AND TSTMS
WILL PROVIDE A PERIOD OF REDUCED SMOKE COVERAGE THROUGH PART OF THE
EVENING.

ISOLD-SCT SHWRS/TSTMS EAST OF THE SIERRA WILL SPAWN A FEW SHORT
LIVED OUTFLOW-INDUCED CELLS IN PARTS OF WRN NV AND NERN CA THRU 03Z
THIS EVENING MAINLY SOUTH AND WEST OF A CEDARVILLE TO PYRAMID LAKE
TO FALLON LINE. LOCALLY HEAVY RAIN...SMALL HAIL AND OUTFLOW OR
DOWNDRAFT GUSTS OF 40-50 MPH WILL BE MAIN THREATS FROM THE STRONGER
CELLS. MJD
