AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
242 AM PDT THU JUL 29 2010

.SHORT TERM...
RADAR ECHOES ARE STILL BEING TRACKED OVER MINERAL AND SRN
CHURCHILL COUNTIES...WITH SOME NEW DEVELOPMENT IN NWRN NV NORTH
AND WEST OF GERLACH. SO FAR ONLY A FEW LIGHTNING STRIKES HAVE BEEN
DETECTED IN MINERAL COUNTY. THE 00Z GFS INDICATED AN UPPER LEVEL
SHORTWAVE IN NWRN NV BUT QUICKLY MOVES THIS FEATURE OUT OF THE
REGION AND DRIES OUT THE MID LEVELS AFT 12Z. THE FINAL DECISION ON
WHETHER TO CARRY ANY ISOLD TSTMS BEYOND 12Z WILL BE MADE WITHIN
THE NEXT HOUR BASED ON RADAR/SATELLITE TRENDS.

FOR THIS AFTERNOON...POTENTIAL FOR ANY TSTMS IN MINERAL AND MONO
COUNTIES IS MARGINAL AS SHORTWAVE ENERGY EXITS THE REGION. 500 MB
MOISTURE WILL BE SUFFICIENT FOR AFTN TCU BUILDUPS AND POSSIBLY A
CB OR TWO ESPECIALLY IN MINERAL AND ERN MONO COUNTIES. FOR
CONTINUITY WITH PREV FORECAST...WILL LEAVE THE MINIMUM POP VALUE
OF 10 PERCENT FOR MENTION OF THUNDER IN PLACE BTWN 21Z-03Z TODAY.

OTHERWISE...VERY DRY AND STABLE CONDITIONS WITH VIRTUALLY NO CLOUD
COVERAGE...AND MAX TEMPS NEAR OR SLIGHTLY ABOVE SEASONAL NORMALS
WILL PREVAIL FOR FRI-SAT AS TROF OFF THE WEST COAST SWINGS INLAND
ACROSS THE NWRN US FRI NIGHT. THIS TROF PASSAGE WILL BRING SOME
INCREASE IN AFTN-EVE WINDS BOTH DAYS ESPECIALLY FOR PARTS OF NWRN
NV-NERN CA AND THE SIERRA FRONT. SEE THE FIRE WEATHER SECTION
BELOW FOR MORE SPECIFIC DETAILS ON WINDS FOR FRI-SAT. MJD

.LONG TERM...SUNDAY THROUGH WEDNESDAY...

MODELS SHOWING SIGNS OF INCONSISTENCY...ESPECIALLY THE ECMWF/S
PATTERN OVER THE NORTHEAST PACIFIC NEXT WEEK.  00Z ECMWF HAS A MUCH
FLATTER RIDGE OVER THE ROCKIES CLOSER TO THE GFS...THAN YESTERDAYS
00Z SOLUTION...WITH A DRIER WEST-SOUTHWEST FLOW OVER THE AREA
THROUGH MID WEEK.  00Z GFS HAS MAINTAINED ITS DEEPER TROUGH AND
CLOSED LOW ALONG THE PACIFIC NORTHWEST COAST PRODUCING A DRY AND
STABLE SOUTHWEST FLOW OVER THE SIERRA AND WESTERN NEVADA.

MAIN IMPACT HERE IS FOR FIRE WEATHER AS THE GFS AND THE LATEST 00Z
ECMWF WOULD PRODUCE A POTENTIALLY WEEK LONG PERIOD OF BREEZY
AFTERNOON AND EVENING WINDS WITH LOW TO VERY LOW HUMIDITY.
TEMPERATURE WILL REMAIN NEAR TO SLIGHTLY ABOVE NORMAL.  BRONG

&&

.FIRE WEATHER...

MAIN CONCERN IS VERY DRY SOUTHWEST FLOW THAT COULD AFFECT THE AREA
INTO NEXT WEEK.  LATE JULY AND EARLY AUGUST CLIMATOLOGY FOR A DRY
SOUTHWEST FLOW IS AFTERNOON HUMIDITY AT 5-15% ACROSS THE AREA AND A
HIGH PROBABILITY OF POOR OVERNIGHT RECOVERY.

UPPER LOW OFF THE PACIFIC NORTHWEST COAST AND JET WILL PUSH INTO
OREGON ON FRIDAY WITH INCREASING SURFACE GRADIENTS.  GUSTY AFTERNOON
WINDS WILL CONTINUE TO TODAY ALONG THE SIERRA FRONT AND EASTERN
SLOPES. GOOD POTENTIAL FOR PEAK GUSTS ALONG US-395 FROM
SUSANVILLE TO MAMMOTH COULD REACH 30 MPH WITH SLIGHTLY HIGHER
GUSTS IN A FEW LOCATIONS MUCH LIKE YESTERDAY. RIDGE WINDS IN THE
MODELS LOOK AT BIT HIGHER THAN YESTERDAY AND LAST LONGER INTO THE
EVENING...SO VALLEY GUSTS IN THE 25-30 MPH MAY CONTINUE UNTIL 10
PM THIS EVENING.

FIRE WEATHER WATCH FOR FRIDAY AFTERNOON THROUGH SATURDAY EVENING
LOOKS GOOD WITH GUSTS 30-35 MPH BOTH DAYS AND POTENTIAL FOR 10-15
MPH OF WIND OVERNIGHT ON MID AND UPPER SLOPES WITH POOR HUMIDITY
RECOVERY.  MODELS DIFFER A BIT ON WHICH DAY WILL HAVE THE STRONGER
WINDS...WITH THE GFS/ECMWF FAVORING FRIDAY AND THE NAM FAVORING
SATURDAY. EITHER WAY...HIGH CONFIDENCE BOTH DAYS WILL SEE AT
LEAST GUSTS NEAR 30 MPH.

FLOW ALOFT WEAKENS A BIT SUNDAY...BUT WITH RIDGE OFF TO THE EAST AND
TROUGH/UPPER LOW NEAR THE PACIFIC NORTHWEST COAST BREEZY AFTERNOON
AND EVENING WINDS WITH LOW HUMIDITY SHOULD CONTINUE INTO NEXT WEEK.
BRONG

&&

.AVIATION...

UPPER LOW NEARING THE PACIFIC NORTHWEST COAST TODAY.  DRY SOUTHWEST
FLOW OVER RENO-TAHOE WILL KEEP VFR CONDITIONS THROUGH THE WEEKEND.
GUSTY AFTERNOON/EVENING WINDS WILL AFFECT THE TERMINALS EACH DAY
WITH PEAK GUSTS AT 25-30 KTS.

AS THE LOW NEARS ANY LINGERING MOISTURE SHOULD BE PUSHED WELL TO
THE EAST BY TONIGHT...FINALLY PUTTING AN END TO THE PERIOD OF
NOCTURNAL CONVECTION WITH THE JET OVERHEAD. BRONG
