AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
245 PM PDT SAT AUG 11 2007

.SHORT TERM...
FOR SUNDAY THROUGH TUESDAY...UPPER LOW/TROF REMAINS OFF THE PACIFIC
NW COAST WITH A STRONG AND PERSISTENT HIGH PRESSURE SYSTEM CENTERED
FROM THE FOUR CORNERS INTO THE SOUTHERN PLAINS. THIS SCENARIO WILL
KEEP SOUTHWEST FLOW ALOFT ACROSS NEVADA WITH THE STRONGEST GRADIENT
ON SUNDAY.

MONSOONAL MOISTURE WILL BEGIN TO ADVECT INTO NEVADA FROM AZ ON
SUNDAY...PUSHING INTO SOUTHERN AND CENTRAL NEVADA. BELIEVE THAT BOTH
NAM AND GFS ARE TOO FAST WITH SPREADING MOISTURE INTO WESTERN NV
SUNDAY BUT MOISTURE SHOULD BE ABLE TO SPREAD INTO REGION BY MONDAY.
MONDAY AND TUESDAY PRECIPITABLE WATER (PW) VALUES OF OVER .50 INCHES
SPREAD ACROSS ALL BUT FAR NW NEVADA WITH OVER .75 INCHES ACROSS
MINERAL AND CHURCHILL COUNTIES. THIS COMBINED WITH MARGINAL
INSTABILITY ACROSS MINERAL INTO CHUCHILL/PERSHING COUNTIES WOULD
POINT TOWARD A THREAT OF ISOLATED THUNDERSTORMS...HOWEVER THERE IS A
STRONG MID-LEVEL CAP IN PLACE AROUND 500 MILLIBARS WHICH WILL
SUPPRESS CONVECTION. WITH NO TRIGGER TO LIFT OR ERODE THIS CAP
THROUGH TUESDAY EXPECT LITTLE OR NO CONVECTION TO DEVELOP UNLESS LOW
LEVEL CONVERGENCE MAINLY ACROSS MINERAL COUNTY IS STRONG ENOUGH TO
ENHANCE FORCING/LIFT.

CURRENT FORECAST HAS ISOLATED THUNDERSTORMS IN THE MINERAL COUNTY
AREA FOR MON-TUE AND WILL LEAVE THOSE IN ALTHOUGH CONFIDENCE IS NOT
VERY HIGH THAT THEY WILL OCCUR.

EXPECT GUSTY SURFACE WINDS THROUGH THIS EVENING AND AGAIN SUNDAY
AFTERNOON AND EVENING AS SURFACE AND THERMAL GRADIENTS COMBINE WITH
STRONGER UPPER LEVEL WINDS. BY MONDAY AND TUESDAY WINDS WILL NOT BE
AS STRONG AS PACNW LOW RETROGRADES SOUTHWEST AND FOUR CORNERS HIGH
BUILDS WEST...RESULTING IN WEAKER UPPER LEVEL WINDS.

TEMPERATURES WILL REMAIN ABOVE NORMAL BY SEVERAL DEGREES THROUGH
MIDWEEK BEFORE COOLING THURSDAY AND FRIDAY. JAH

.LONG TERM...WEDNESDAY THROUGH SATURDAY...
THE BATTLE BETWEEN THE STRONG RIDGE OVER THE SOUTH CENTRAL US AND
THE TROF MOVING INTO THE NWRN US WILL CONTINUE INTO NEXT WEEKEND.
THE GFS IS MORE AGGRESSIVE WITH THE TROF THAN THE ECMWF AND THE
ENSEMBLE MEAN...WHICH WOULD RESULT IN MORE SIGNIFICANT COOLING FOR
THURS-FRI. THE CURRENT FORECAST WILL FAVOR THE MORE MODEST COOLING
SCENARIO DUE TO THE ANOMALOUS STRENGTH OF THE RIDGE WHICH WILL BE
DIFFICULT TO DISPLACE WITH THE STORM TRACK STILL SO FAR NORTH OF THE
FORECAST AREA. TEMPS WILL STILL FALL BELOW NORMAL BY THURSDAY WITH
VALLEYS MAINLY IN THE MID-UPR 80S...FOLLOWED BY GRADUAL WARMING TO
NEAR NORMAL AGAIN BY NEXT WEEKEND...ALTHOUGH THE ECMWF DOES HINT AT
A POSSIBLE SECONDARY TROF PASSAGE SATURDAY WHICH WOULD LEVEL OFF OR
REVERSE THIS SLOW WARMING TREND BY THEN. THE STRONGEST WINDS ARE
LIKELY ON WEDNESDAY IN ASSOCIATION WITH THE COLD FRONT
PASSAGE...WITH LOCALLY BREEZY W-NW WINDS INTO THURS AS STRONGER
RIDGE WINDS FROM THE MORNING MIX DOWN INTO THE LOWER ELEVATIONS.
MODERATE WINDS WILL BE KEPT FOR FRI-SAT WITH THE POSSIBILITY OF
NUDGING UP THE SPEEDS IF THE SECONDARY TROF PASSAGE INDICATED BY THE
ECMWF IS MAINTAINED AND PICKED UP BY OTHER SOURCES OF MEDIUM RANGE
GUIDANCE.

THE ONLY THREAT OF ISOLD CONVECTION IN THE EXTENDED PERIOD WILL BE
LIMITED TO THE FAR SRN ZONES ON WED AFTERNOON WHERE SLGT INSTBY WILL
STILL BE IN PLACE BEFORE THE TROF AND COLD FRONT SWING THRU THE
REGION. VERY DRY AND STABLE AIR MASS WILL DOMINATE FROM THURS-SAT
WITH LITTLE OR NO CLOUD COVER EXPECTED. MJD
&&

.AVIATION...
VFR THRU SUNDAY. LEE SIDE SW-W WINDS WITH GUSTS AROUND 30 KT BOTH
DAYS THIS WEEKEND BTWN 22Z-04Z. WIND DIRECTION SOUTH-SSE AT TIMES AT
KRNO BEFORE 00Z EACH DAY. MJD

&&

.FIRE WEATHER...
TROUGH OF LOW PRESSURE DIVING SOUTH OUT OF THE GULF OF ALASKA TOWARD
NOR CAL COAST WHILE A WEAK LOW OFF THE BAJA COAST IS PUSHING
MONSOONAL MOISTURE NORTH INTO SOUTHERN CALIFORNIA AND SOUTHERN
NEVADA. PRESSURE GRADIENT CONTINUES TO STRENGTHEN THIS AFTERNOON AND
WILL REMAIN TIGHT THROUGH SUNDAY EVENING. LOW END RED FLAG WARNING
STILL LOOKS ON TRACK FOR THE REST OF THE AFTERNOON IN THE DESERTS TO
THE LEE OF THE SIERRA UNTIL AROUND 9 PM. GRADIENTS AND UPPER LEVEL
FLOW REMAINS STRONG SUNDAY...ALTHOUGH SOME MOISTURE IS PROGGED TO
MOVE INTO THE SOUTHERN HALF OF THE FORECAST AREA BY LATE TOMORROW
AFTERNOON. BELIEVE MODELS ARE TOO FAST IN BRINGING MOISTURE TO THE
AREA. ALSO...EXPECT LOWER LEVELS WILL REMAIN DRY WITH RHS MEETING
RED FLAG CRITERIA. THEREFORE...HAVE UPGRADED THE WATCHES FOR SUNDAY
TO RED FLAG WARNINGS. WINDS FOR MONO COUNTY LOOK TO BE STRONGEST
NORTH OF MONO LAKE AND HAVE WORDED STATEMENTS AS SUCH.

HAVE LEFT ZONES 459 AND 453 OUT OF THE THE WARNING FOR
SUNDAY...ALTHOUGH THIS SHOULD BE MONITORED AS PORTIONS OF THESE
ZONES COULD REACH RED FLAG CRITERIA. ALTHOUGH...DIDNT FEEL IT WOULD
BE WIDESPREAD ENOUGH TO WARRANT A WARNING.

WINDS DECREASE MONDAY AND TUESDAY AS RIDGE STRENGTHENS OVER THE AREA
WHILE MOISTURE INCREASES SOUTH OF HIGHWAY 50. THIS COULD LEAD TO
ISOLATED MOSTLY DRY CONVECTION. ANOTHER STRONG TROUGH TO PUSH INTO
NORTHERN CALIFORNIA AROUND THE WED-THURS TIME FRAME. THIS WILL
RESULT IN ANOTHER BOUT OF WINDS AND LIKELY LEAD TO ADDITIONAL RED
FLAG STATEMENTS.   MILNE
