AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
200 PM PDT FRI JUN 1 2012

.SHORT TERM...

VERY WARM TEMPERATURES TODAY ACROSS THE REGION, WITH RECORD HIGH
TEMPERATURES LIKELY. RECORD HIGH TEMPERATURE FOR JUNE 1ST IN RENO
WAS SET BACK IN 2007, AT 94 DEGREES. WE WILL HAVE TO SEE LATER THIS
AFTERNOON IF WE BREAK THE RECORD OR NOT, BUT SO FAR WE'RE ON TRACK.
SEE PUBLIC INFORMATION STATEMENT FOR A LIST OF LOCAL RECORD HIGHS
FOR JUNE 1ST.

A WEAKNESS IN THE RIDGE IS MOVING OVER CA/NV TODAY, WITH COOLING
TEMPERATURES ALOFT. WE'RE ALREADY STARTING TO SEE TOWERING CUMULUS
OVER THE EASTERN SIERRA AND WESTERN NEVADA. MORNING SOUNDING HAD A
WEAK CAP AT 450MB, BUT AS SOON AS THE HEATING OVERCOMES THIS CAP,
ISOLATED TO SCATTERED THUNDERSTORMS WILL DEVELOP ACROSS THE REGION.
CONVECTION WILL DEVELOP OVER THE HIGHER TERRAIN AND LASSEN
CONVERGENCE ZONE FIRST, THEN PUSH EASTWARD INTO WESTERN NEVADA BY
LATE AFTERNOON AND INTO THE EVENING. WITH THE VERY WARM TEMPERATURES
IN THE GREAT BASIN TODAY (LOVELOCK SHOULD BE UP TO NEAR 100
DEGREES), THE THERMAL TROUGH WILL SHIFT INTO CENTRAL NEVADA AND
WESTERLY ZEPHYR WIND WILL PUSH ALL CONVECTION OUR OF THE TAHOE BASIN
THIS EVENING AND EAST OF HIGHWAY 395. THIS AREA OF LOW-LEVEL
CONVERGENCE ALONG AND EAST OF HIGHWAY 395 WILL BE THE AREA OF
GREATEST THUNDERSTORM COVERAGE.

THE MAIN THREAT FROM THUNDERSTORMS TODAY WILL BE GUSTY
OUTFLOW WINDS OF UP TO 50 MPH OR MORE. THERE MAY BE SOME SMALL HAIL
AS WELL, BUT THE DRY BOUNDARY LAYER WILL PROVIDE A FAVORABLE
ENVIRONMENT FOR DOWNBURST WINDS. THUNDERSTORMS WILL ALSO HAVE
MODERATE OR LOCALLY HEAVY RAINFALL, BUT A FEW NEW LIGHTNING STARTS
COULD BE POSSIBLE.

THUNDERSTORM ACTIVITY SHOULD WIND DOWN AFTER MIDNIGHT, ALTHOUGH
LATEST MODELS ARE SHOWING POTENTIAL FOR A FEW SHOWERS LINGERING
THROUGH THE OVERNIGHT AS THEY MOVE EAST OF GERLACH/LOVELOCK.

TEMPERATURES COME DOWN A FEW DEGREES ON SATURDAY AS WE GET SLIGHTLY
COOLER TEMPS ALOFT, BUT STILL WELL ABOVE NORMAL. ISOLATED
THUNDERSTORMS WILL BE POSSIBLE NEAR THE OREGON BORDER AND SOUTH INTO
MINERAL COUNTY, DUE TO SOME LINGERING MOISTURE/INSTABILITY.
AFTERNOON WINDS WILL INCREASE TO THE AROUND 30 MPH.

MUCH DEEPER AND COLDER LOW PRESSURE SYSTEM IS SET TO MOVE INTO
NORTHERN CA/NV BY EARLY NEXT WEEK. THIS WILL INCREASE OUR WINDS
STARTING SUNDAY, WITH GUSTS TO 35MPH. THERMAL AND PRESSURE GRADIENTS
WILL INCREASE IN RESPONSE TO THE DEEPENING TROUGH AND JET MOVING
INTO THE REGION, WITH WINDS ON MONDAY INCREASING WITH GUSTS AROUND
45MPH OR MORE.

ECMWF AND GFS HAVE BEEN SHOWING A SOLID PRECIPITATION EVENT AS WELL,
ESPECIALLY IN THE SIERRA MONDAY AFTERNOON AND MONDAY NIGHT.
CONFIDENCE IS RISING WITH REGARD TO RAINFALL IN THE SIERRA OF OVER
0.5" AND OVER 0.25" ALONG THE SIERRA FRONT NORTH OF RENO (INCLUDING
SUSANVILLE). SNOW LEVELS WILL START OUT VERY HIGH, THEN COME DOWN TO
AS LOW AS 5000 FEET TUESDAY MORNING. LATEST GFS IS A LITTLE
DISCOURAGING THROUGH, WITH A TREND OF LESS QPF FOR THE RENO-TAHOE
AREA. DIDN'T LOWER ANY POPS OR QPF THOUGH, AS THIS IS PROBABLY AN
OUTLIER COMPARED TO ECMWF/GEM.  HOON

.LONG TERM...TUESDAY THROUGH FRIDAY...

MADE ONLY MINOR TWEAKS TO THE EXTENDED GRIDS WITH THIS PACKAGE AS
THERE IS SOME UNCERTAINTY AS TO HOW QUICKLY THE COLD TROUGH DEPARTS
THE FORECAST AREA TUESDAY INTO TUESDAY NIGHT. THE 12Z GFS TRENDED
SLOWER...WITH QUITE A BIT OF SPREAD AMONGST THE MEMBERS OF THE 12Z
GFS ENSEMBLE. THE 12Z GEM AND ECMWF ARE FASTER...WITH THE TROUGH
LIFTING ACROSS NORTHEAST NEVADA TUESDAY AFTERNOON. THE BEST CHANCE
OF SHOWERS ON TUESDAY WILL BE NORTH OF INTERSTATE 80. WITH H700
TEMPS PROGGED TO BE NEAR -8C MIDDAY TUESDAY ACROSS THE NORTH...A MIX
OF RAIN AND SNOW SHOWERS ARE POSSIBLE ON TUESDAY AT HIGHER
ELEVATIONS ABOVE 6000 FT. HIGH TEMPS ON TUESDAY WILL BE WELL BELOW
NORMAL...WITH HIGHS STRUGGLING TO REACH THE MID 60S ACROSS WESTERN
NEVADA VALLEYS.

TEMPS WILL GRADUALLY WARM THROUGH THE REMAINDER OF THE WORK WEEK AS
A SHORTWAVE RIDGE OF HIGH PRESSURE BUILDS ALONG THE WEST COAST.
MYRICK

&&

.AVIATION...

THE MAIN OPERATIONAL CONCERN THROUGH EARLY THIS EVENING WILL BE THE
POTENTIAL FOR GUSTY AND ERRATIC OUTFLOW WINDS AND SMALL HAIL NEAR
THUNDERSTORMS. THE BEST CHANCE OF SCT STORMS WILL BE JUST EAST OF
THE SIERRA ALONG THE 395 CORRIDOR THROUGH 23Z...THEN PUSHING TO THE
EAST ACROSS THE WESTERN NEVADA BASIN AND RANGE THROUGH EARLY THIS
EVENING. OTHERWISE...WINDS WILL BE LIGHT WITH VFR CONDS EXPECTED
THROUGH SATURDAY. MYRICK

&&

.FIRE WEATHER...
THUNDERSTORMS ALREADY DEVELOPING AS OF 1300 ALONG CONVERGENCE ZONES
IN NORTHERN LASSEN/WASHOE COUNTIES AND IN SOUTHERN MONO/MINERAL
COUNTIES. WEAK WESTERLY FLOW WILL DEVELOP AFTER 1600 PUSHING STORMS
ACROSS THE SIERRA FRONT AND BASIN AND RANGE THROUGH THE EVENING.
WITH TEMPERATURES IN THE HIGH 90S TO NEAR 100 DEGREES COMBINED WITH
DRY AIR NEAR THE SURFACE ACROSS WESTERN NEVADA, THE MAIN CONCERN
WITH THUNDERSTORMS WILL BE FOR GUSTY OUTFLOW WINDS, ESPECIALLY EAST
OF THE SIERRA FRONT. LIGHTNING IS EXPECTED WITH THESE STORMS AND IF
STRIKES OCCUR OUTSIDE OF MAIN PRECIPITATION CORES THEN FIRE STARTS
ARE POSSIBLE.

OVER THE WEEKEND, A TROUGH APPROACHING THE WEST COAST WILL BRING
INCREASED WINDS TO EASTERN CA AND WESTERN NEVADA WITH THE POTENTIAL
FOR NEAR CRITICAL CONDITIONS BY LATE SATURDAY AFTERNOON AND EVENING.
WEST TO SOUTHWEST FLOW WILL INCREASE ALONG WITH A STRENGTHENING
SURFACE GRADIENT TO PRODUCE WINDS 10 TO 20 MPH WITH GUSTS 25 TO 30
MPH IN THE AFTERNOON. GUSTY WINDS AND LOW RH WILL CREATE
MARGINAL CRITICAL CONDITIONS FOR SATURDAY AFTERNOON, AND COULD
BE HIGH IMPACT IF THERE ARE ANY ACTIVE FIRES FROM LIGHTNING STARTS
ON THIS AFTERNOON AND EVENING.

FOR SUNDAY, STRONGER WINDS ARE EXPECTED, BUT WITH THE TROUGH PULLING
IN MOISTURE, AFTERNOON HUMIDITIES MAY CLIMB ABOVE CRITICAL LEVELS.
MODEL DISAGREEMENT WITH TIMING OF THE TROUGH PASSAGE HAS LED TO LOW
CONFIDENCE WITH WHEN MOISTURE WILL MOVE INTO WESTERN NEVADA. WIND
GUSTS 30 TO 35 MPH MAY CREATE LOCALIZED CRITICAL FIRE WEATHER
CONDITIONS, ESPECIALLY SOUTH OF INTERSTATE 80 SUNDAY AFTERNOON, BUT
CONFIDENCE NOT HIGH ENOUGH FOR A WATCH AT THIS TIME.

FOR NOW, DECIDED TO HEADLINE THE FIRE WEATHER FORECAST WITH
SCATTERED THUNDERSTORMS AND GUSTY OUTFLOW WINDS FOR THIS EVENING,
AND NEAR CRITICAL CONDITIONS FROM GUSTY WINDS AND LOW HUMIDITIES FOR
SATURDAY AND SUNDAY AFTERNOONS.

STRONG TROUGH MOVES ONSHORE LATE SUNDAY NIGHT INTO MONDAY WITH HIGH
CONFIDENCE FOR STRONG WINDS AS GUSTS COULD EXCEED 45 MPH. AS THE
COLD FRONT PASSES THROUGH THE REGION MONDAY, IT WILL BRING COLDER
TEMPERATURES, INCREASE HUMIDITY AND BRING BETTER CHANCES FOR WETTING
RAINS. RAINS COULD BE SIGNIFICANT IN SIERRA FROM TAHOE NORTH WITH UP
TO 1 INCH POSSIBLE. LINDAMAN
