AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
323 PM PDT FRI AUG 10 2007

.SHORT TERM...
SW FLOW ALOFT WILL INCREASE THIS WEEKEND AS UPPER LOW APPROACHES
THE SWRN CANADA COAST WHILE STRONG RIDGE PREVAILS OVER THE SRN
PLAINS. DRY AND STABLE AIR MASS WILL REMAIN OVER THE REGION THRU
SUNDAY AS WEAK SHORTWAVES WITHIN THE SW FLOW BRING SOME INCREASE
IN SW-W WIND EACH DAY...WITH SLIGHTLY STRONGER WINDS ON SUNDAY. MAX
TEMPS WILL REMAIN NEAR NORMAL WITH MOST VALLEYS REACHING THE LOWER
90S THIS WEEKEND.

BY MONDAY...THE RIDGE IS EXPECTED TO EXPAND INTO THE CNTRL PLAINS
AND ERN GREAT BASIN...BRINGING A FEW DEGREES OF WARMING TO THE
REGION WITH MOST VALLEYS IN THE MID 90S. THE SW FLOW ALOFT WILL
WEAKEN ESPECIALLY OVER THE SRN ZONES WHILE HIGH LEVEL MOISTURE
SPREADS FROM SOUTH TO NORTH. THE WEAKER FLOW COMBINED WITH
INCREASED HEATING WILL BRING AFTERNOON CUMULUS BUILDUPS TO THE
MINERAL-MONO ZONES WITH ISOLD BRIEF TSTMS POSSIBLE. HOWEVER...IF
THE CIRRUS COMES IN THICK ENOUGH...CONVECTION WOULD NOT OCCUR AND
MAX TEMPS WOULD THEN NEED TO BE LOWERED A BIT ALONG WITH A
CORRESPONDING INCREASE IN MIN TEMPS FOR MON NIGHT. CURRENT
THINKING IS THAT HIGH CLOUDS WILL NOT HAVE A SIGNIFICANT EFFECT ON
DAYTIME TEMPS FOR MONDAY. MJD

.LONG TERM...TUESDAY THROUGH FRIDAY...
NUDGED TEMPERATURES TOWARDS BIAS-CORRECTED GUIDANCE (LESS SO DAYS
6 AND 7)..OTHERWISE MINIMAL CHANGES TO EXTENDED GRIDS.

WESTERN NEVADA AND NORTHEAST CALIFORNIA WILL REMAIN BETWEEN AN
EASTERN PACIFIC TROUGH AND A CENTRAL CONUS RIDGE THROUGH THE
EXTENDED. A WEAK PIECE OF ENERGY WILL BE EXPELLED OUT OF THE TROUGH
AND INTO THE PACIFIC NORTHWEST THURSDAY. THIS IS EXPECTED TO
INCREASE WEST WINDS OVER THE NORTHERN PORTION OF THE CWA AND KICK
INSTABILITY (AT LEAST ENOUGH INSTABILITY FOR THUNDERSTORMS) OUT OF
MINERAL COUNTY. SLIGHT CHANCE POPS OVER EASTERN MONO COUNTY AND OUT
INTO MINERAL COUNTY FOR TUESDAY AND WEDNESDAY STILL LOOK
APPROPRIATE.

TEMPERATURES FAIRLY STEADY-STATE...WITH HIGHS WITHIN 5 DEGREES OF
NORMAL (STATISTICALLY INSIGNIFICANT) EXCEPT ON TUESDAY AND WEDNESDAY
OUT IN THE BASIN FROM LOVELOCK TO HAWTHORNE...WHERE HIGHS ARE
EXPECTED TO PEAK OUT 5-8 DEGREES ABOVE NORMAL. SNYDER
&&

.AVIATION...
CIGS UNLIMITED WITH NO CONCERNS THROUGH SATURDAY. SNYDER
&&

.FIRE WEATHER...
LOW PRESSURE WILL DROP SOUTH TO JUST OFF THE WA COAST BY SATURDAY
AND MOVE EAST ON SUNDAY. FLOW ALOFT INCREASES ON SATURDAY WITH A
65-70 KT JET MOVING NORTH TOWARD THE SRN PORTION OF THE AREA. THE
JET LIFTS NORTH SATURDAY NIGHT AND SUNDAY AND STRENGTHENS. THE
SURFACE GRADIENT TIGHTENS SOME ON SATURDAY AND MORE SO ON SUNDAY AS
THE SYSTEM MOVES OFF TO THE EAST AND HIGH PRESSURE BEGINS BUILDING
NORTHWEST INTO THE AREA. RIGHT NOW THE WINDIER DAY LOOKS TO BE
SUNDAY WITH WIND GUSTS 30-35 MPH (EVEN 40 MPH IN SOME WINDIER
LOCATIONS) AND HUMIDITIES BELOW 15%. A FIRE WEATHER WATCH WAS ISSUED
FOR SUNDAY FOR ALL BUT MINERAL AND CHURCHILL/PERSHING COUNTIES.
MINERAL COUNTY MAY NEED TO BE ADDED IF WINDS APPEAR THAT THEY WILL
BE STRONGER. WATCHES ARE WELL COORDINATED WITH SURROUNDING OFFICES.

SATURDAY MAY NEED TO BE LOOKED AT AGAIN THIS EVENING AS LOW END
CRITERIA MAY BE MET...ESPECIALLY ALONG THE SIERRA FRONT AND IN
MONO/TAHOE ZONES. JET STREAK MOVES THROUGH WITH THE SHORT WAVE
ENERGY EARLY SATURDAY MORNING WHICH SHOULD INCREASE RIDGE WINDS
DURING THE OVERNIGHT PERIOD...AND WE SHOULD SEE A DECREASE BY
SATURDAY AFTERNOON/EVENING. IF SHORT WAVE AND JET STREAK WERE TO
MOVE THROUGH DURING THE AFTERNOON HOURS THEN IT MIGHT BE MORE OF A
FACTOR. SWING AND MID SHIFT CAN TAKE A LOOK AND SEE IF A RED FLAG IS
NECESSARY. THE MODELS THIS MORNING WERE THE FIRST TO SHOW THAT
SATURDAY MAY BE A LITTLE STRONGER SO WOULD LIKE TO SEE HOW TODAY
PANS OUT AND ANOTHER MODEL RUN.

OTHERWISE A BREAK IN THE WIND EXPECTED MONDAY AND TUESDAY BEFORE
ANOTHER ROUND OF POTENTIAL RED FLAG DAYS MOVES IN BY THE MIDDLE OF
NEXT WEEK. BENINATO
