AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
252 AM PDT MON JUN 1 2009

.SHORT TERM...
PREVIOUS FORECAST LOOKING RIGHT ON TRACK EXCEPT FOR A FEW MINOR
TWEAKS. UPPER LOW OFF THE CA COAST IS SLOWLY MOVING CLOSER TO THE
AREA...WITH A SHORTWAVE TROUGH/TROP FOLD ROTATING AROUND THE MAIN
LOW EXPECTED TO MOVE INTO CALIFORNIA TODAY. THIS VORT MAX WILL BE
MOVING INTO NORTHERN CA LATE THIS AFTERNOON...BECOMING NEGATIVELY
TILTED AND ENHANCING THE CONVECTION ACROSS THE REGION WITH
DIFFLUENCE ALOFT THROUGH THE EVENING.

TODAY WILL BE AN INTERESTING DAY FOR THUNDERSTORMS...MAINLY BECAUSE
THE FOCUS WILL CHANGE TO MORE ORGANIZED ENVIRONMENT WITH INCREASED
SHEAR ALOFT...AS OPPOSED TO THE PULSE TYPE CONVECTION WE HAVE SEEN
OVER THE LAST FEW DAYS. STORMS THAT DEVELOP TODAY WILL HAVE DECENT
MOVEMENT TO THE NORTH TODAY...WITH LESS OF A FLASH FLOODING THREAT
UNLESS STORMS BEGIN TO TRAIN OVER THE SAME AREAS. THERE IS STILL
ABUNDANT MOISTURE IN THE ATMOSPHERE...ALTHOUGH I EXPECT THIS
MORNINGS SOUNDING TO COME IN DRIER THAN WHAT WE SAW YESTERDAY
MORNING.

CONVECTION IS EXPECTED TO INITIATE THIS MORNING IN THE HIGH SIERRA
FROM TAHOE INTO MONO COUNTY...AS WELL AS UP NORTH IN THE LASSEN
CONVERGENCE ZONE...PUSHING OFF TO THE NORTHEAST. WITH THE SHORTWAVE
MOVING UP THE CA COAST THIS MORNING...EXPECT STORMS TO START OUT
FAIRLY RUN-OF-THE-MILL...BUT AS THE SHORTWAVE GETS CLOSER TO THE
AREA AND INCREASES SHEAR AND LIFT SOME STORMS WILL BECOME MORE
ORGANIZED AND LONGER LIVED. COVERAGE WILL BECOME MORE NUMEROUS IN
THE LATE AFTERNOON AND INTO THE EVENING SPREADING NORTHWARD AS WE GET
THE ENHANCEMENT FROM THE SHORTWAVE. AREAS NORTH AND EAST OF
RENO-TAHOE LOOK TO HAVE THE BEST CHANCES FOR SEVERE STORMS LATE
THIS AFTERNOON AND EVENING...WHERE BEST INSTABILITY AND SHEAR COME
TOGETHER. THUNDERSTORM ACTIVITY WILL DECREASE IN THE SIERRA BY LATE
AFTERNOON AND IN THE RENO AREA BY EARLY EVENING AS WE STABILIZE WITH
WESTERLY WINDS. MAIN THREAT WILL BE STRONG OUTFLOW WINDS AND HAIL
WITH THE STRONGEST STORMS. CONVECTION WILL CONTINUE INTO TONIGHT
AHEAD OF THE FORCING...TAPERING OFF AFTER MIDNIGHT AS THE SHORTWAVE
ROTATES OUT OF THE AREA.

THE LOW PRESSURE OFF THE CA COAST CONTINUES TO MOVE CLOSER ON
TUESDAY WITH MORE SHOWERS AND THUNDERSTORMS EXPECTED AGAIN AS WE
DESTABILIZE FROM COOLING TEMPERATURES ALOFT. MODELS ARE SHOWING PW
VALUES INCREASING TO NEAR ONE INCH TUESDAY...WHICH WOULD INCREASE THE
THREAT FOR FLASH FLOODING...BUT STORMS WILL HAVE FAST MOVEMENT AS
WINDS INCREASE THE CLOUD BEARING LAYERS. THIS WILL NEED TO BE
MONITORED.

WEDNESDAY LOOKS TO BE BEST DAY YET IN TERMS OF SEVERE THUNDERSTORM
CHANCES. NOSE OF THE JET WILL MOVE INTO NORTHERN CA WITH DIFFLUENCE
IN THE UPPER LEVELS LOOKING VERY FAVORABLE FOR INTENSE
THUNDERSTORMS. MODEL SOUNDINGS ARE SHOWING LONG CURVED HODOGRAPHS
FAVORABLE FOR ORGANIZED STRONG STORMS...AND POSSIBLE SUPERCELL
DEVELOPMENT. MODELS HAVE BEEN FLOPPING A BIT ON THE DAY THAT THE JET
NOSES IN...BUT WHENEVER THE JET DOES MOVE IN...THIS WILL END UP
BEING THE BEST DAY FOR SEVERE STORMS WITH THE STRONGEST FORCING AND
DIFFLUENCE ALOFT. HOON

.LONG TERM...THURSDAY THROUGH SUNDAY...
MODELS CONTINUE TO SHOW A CUT OFF LOW THAT WILL PROGRESS TOWARDS THE
CENTRAL CA COAST ON THURSDAY BEFORE MOVING NORTHEAST ACROSS THE
REGION THROUGH FRIDAY NIGHT.  GFS CONTINUES TO BE A BIT FASTER THAN
THE EURO IN BRINGING THE SYSTEM ONSHORE AND ACROSS THE AREA.  BUMPED
UP POPS ON THURSDAY WITH GOOD UPPER LEVEL JET SUPPORT AND WEAK VORT
MAXES ROTATING INTO WESTERN NV DURING THE AFTERNOON.  PLENTY OF
INSTABILITY OVER THE AREA AND MOISTURE WILL AID IN PRODUCING SHOWER
AND THUNDERSTORM ACTIVITY ACROSS THE SIERRA AND WESTERN NV.

UPPER LOW IS FORECAST TO MOVE NORTHEAST ACROSS THE FORECAST AREA BY
FRIDAY NIGHT.  WITH COLD POOL OVERHEAD GENERATING INSTABILITY AND
ABUNDANT MOISTURE...WE WILL CONTINUE TO SEE SHOWERS AND
THUNDERSTORMS INTO FRIDAY NIGHT.  UPPER LEVEL SYSTEM PULLS AWAY FROM
THE AREA ON SATURDAY WITH COOL NORTHWESTERLY FLOW DEVELOPING OVER
THE WESTERN CONUS.  EURO HOLDS ON TO PRECIP THROUGH SATURDAY NIGHT
WITH SLOWER MOVEMENT.

ONLY MAJOR CHANGE TO THE GOING FORECAST WAS TO LOWER TEMPERATURES
BOTH FRIDAY AND SATURDAY A GOOD 5-8 DEGREES AREA WIDE.  BOTH MODELS
INDICATING 700 MB TEMPS FROM 0C TO -3C MOVING ACROSS THE REGION AS
THE CORE OF THE LOW MOVES OVERHEAD AND NORTHWEST FLOW SETTING UP.
STAYED WARMER THAN GUIDANCE...WHICH HAD HIGHS ONLY IN THE UPPER 60S
FOR WESTERN NV...WITH HIGHS FRIDAY AND SATURDAY IN THE LOWER 70S IN
WESTERN NV AND 50S IN THE SIERRA.  WE SHOULD START TO SEE A WARM UP
SUNDAY AS WEAK HIGH PRESSURE BUILD ACROSS THE REGION WITH
TEMPERATURES REBOUNDING TO NEAR 80 IN WESTERN NV AND 60S ACROSS THE
SIERRA.  MOZLEY

&&

.AVIATION...

CONDITIONS REMAIN MOIST AND UNSTABLE WITH UPPER LOW OFF THE
CALIFORNIA COAST.  INITIALLY SHOWERS AND THUNDERSTORMS WILL DEVELOP
OVER THE SIERRA 18-21Z...THEN OVER WESTERN NEVADA 20-23Z.  STORMS
CAPABLE OF PRODUCING OUTFLOWS TO 45KTS...HAIL AND HEAVY RAIN.

STORMS IN THE SIERRA SHOULD DIMINISH BY LATE AFTERNOON AND END NEAR
KRNO BY EARLY EVENING.  SHOWERS AND STORMS COULD LAST WELL INTO THE
EVENING NORTH OF SUSANVILLE-LOVELOCK.

UPPER LOW REMAINS STATIONARY UNTIL FRIDAY WITH FAVORABLE CONDITIONS
FOR SHOWERS AND THUNDERSTORMS.  BRONG
