AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
300 PM PST FRI NOV 30 2007

.SHORT TERM...
SHEARING UPPER SHORTWAVE TROUGH CURRENTLY PIVOTING OVER THE CWA AS A
REINFORCING SHORTWAVE DIGS OFF THE COAST HELPING TO CARVE OUT THE
LONGWAVE TROUGH OVER THE WEST COAST. THIS TROUGH COMBINED WITH THE
HIGH AMPLITUDE UPPER RIDGE OVER THE ERN PACIFIC IS SETTING UP A
NORTHERLY JET COMING OUT OF THE NORTH POLE WHICH WILL BRING MUCH
COLDER AIR INTO THE REGION. THE INITIAL COLD FRONT WAS RATHER WEAK
HOWEVER IT WAS ABLE TO TRIGGER A RATHER IMPRESSIVE SNOWBAND THIS
MORNING. COLD AIR WILL CONTINUE TO SETTLE INTO THE AREA BEHIND THE
FRONT WITH VALLEY HIGHS STAYING IN THE 30S ON SATURDAY.

THE PATTERN BEGINS TO CHANGE BY SUNDAY AS A WESTERLY JET ACROSS THE
PACIFIC IS ABLE TO UNDERCUT THE ERN PACIFIC RIDGE AND BRING A WARM
AND WET FLOW INTO THE WEST COAST. THIS JET WILL PRODUCE SIGNIFICANT
AMOUNTS OF PRECIP HOWEVER IT WILL REMAIN NORTH AND WEST OF THE CWA.
THE MOISTURE PLUME SHOULD OCCASIONALLY SAG FAR ENOUGH SOUTH TO BRING
LIGHT PRECIP TO THE FAR NRN ZONES AND WRN LASSEN COUNTY SUNDAY AND
MONDAY SO KEPT WITH AT LEAST SLIGHT CHANCE POPS IN THOSE AREAS. THE
MAIN STORY WITH THIS SYSTEM WILL BE THE HIGH WIND POTENTIAL AS
MODELS GENERATE H7 WINDS AS HIGH AS 80 KTS OVER THE NRN HALF OF THE
CWA. ITS TOUGH TO SAY HOW WELL THESE WINDS WILL MIX DOWN TO THE
SURFACE WITH THE MOIST WAA PATTERN...HOWEVER THE POTENTIAL IS
DEFINITELY THERE FOR STRONG WINDS SUNDAY AND ESPECIALLY MONDAY AS
PRECIP BANKS UP ON THE WRN SLOPES OF THE NRN SIERRA. BUMPED THE
FORECAST WINDS UP TO GET BREEZY OR WINDY WORDING AND WILL CONTINUE
WITH THE SPECIAL WEATHER STATEMENT TO COVER THE WIND POTENTIAL. THE
WINDS WILL ALSO KEEP THE VALLEYS MIXED OUT COMBINING WITH THE WAA TO
BRING DAYTIME TEMPS BACK UP TO NORMAL BY SUNDAY AND INTO THE LOWER
60S BY MONDAY. WITH THE EXCEPTION OF COLDER THAN NORMAL TEMPERATURES
TONIGHT...SIGNIFICANT CLOUD COVER AND OVERNIGHT WINDS WILL KEEP
MINIMUM TEMPS UP THROUGH THE PERIOD. JORDAN

.LONG TERM...TUESDAY THROUGH FRIDAY...
ON TUESDAY A COLD FRONT IS PROGGED TO BE MOVING THROUGH THE NRN
SIERRA AND WRN NEVADA.  THE GFS BRINGS BETWEEN 0.80 AND 1.00 INCH OF
PRECIPITABLE WATER INTO THE NRN AND CNTRL SIERRA BY 00Z WEDNESDAY.
ON WEDNESDAY THE FRONT SHOULD MOVE INTO THE SRN SIERRA AND SRN
NEVADA AS DRIER AIR WORKS INTO THE AREA TO THE NORTH.  HAVE KEPT A
MENTION OF LGT RAIN OVER MUCH OF THE KREV CWFA FOR TUESDAY.  WITH
THE FRONT THEN MOVING SOUTH HAVE KEPT WEDNESDAY DRY.

ON THURSDAY AND FRIDAY THE GFS AND ECMWF BOTH SHOW A STRONG VORTEX
ANCHORED OVER NRN CANADA WITH SHORTWAVE TROUGHS ROTATING THROUGH THE
UPR FLOW. THE FIRST SHORTWAVE IS PROGGED TO MOVE THROUGH THE PACIFIC
NW ON THURSDAY.  THIS FIRST SYSTEM STAYS NORTH OF THE AREA WITH COLD
UPR LVL AIR MOVING ACROSS NRN NEVADA.  THIS COLD AIR ALOFT WILL
GENERATE SOME LLVL INSTABILITY SO WILL CONTINUE WITH A MENTION OF
LGT RAIN OVER NRN LASSEN AND NRN WASHOE COUNTIES. BY FRIDAY A SECOND
SHORTWAVE IS PROGGED TO MOVE ACROSS THE REGION WITH COLDER AIR
ALOFT.  HAVE EXTENDED A SLIGHT CHANCE OF MOUNTAIN SNOW AND VALLEY
RAIN TO MAINLY THE NWRN HALF OF THE CWA.  THE UPR FLOW BECOMES NWLY
SO DO NOT LOOK FOR AS MOIST AN AIR MASS MOVING INTO THE REGION.
SNOW AMOUNTS LOOK LIKE THEY WILL NOT BE TOO IMPRESSIVE ATTM.
HOWEVER IF THIS SECOND SYSTEM CAN TAP MOISTURE FROM A MORE SWLY
TRAJECTORY THEN WE SHOULD SEE A LITTLE MORE SNOWFALL FOR THE UPR
ELEVATIONS.

TEMPERATURES SHOULD START OFF AROUND 10 DEGREES ABOVE NORMAL ON
TUESDAY BUT WILL FALL TO MORE SEASONABLE LEVELS BY FRIDAY AS THE UPR
TROUGH MOVES ACROSS THE WRN GREAT BASIN.  OHARA

.AVIATION...
VFR CONDITIONS WILL CONTINUE ACROSS THE REGION...WITH LCL MVFR
CONDITIONS OVER WRN NEVADA THROUGH 04Z.  WIND SPEEDS WILL BECOME
LIGHT OVERNIGHT BUT WILL BECOME WLY AT 10-15 KT AND GUSTY BY SAT
