AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
312 AM PDT SAT JUL 17 2010

.SHORT TERM...

CURRENT WATER VAPOR IMAGERY DEPICTS A DRY SLOT MOVING IN FROM THE
WEST WHICH IS PUSHING THE MOIST AIR THAT KICKED OFF THUNDERSTORMS
YESTERDAY EAST OF THE AREA. A SHORTWAVE TROUGH IN THE GULF OF ALASKA
WILL BEGIN TO TREK SOUTHEAST TODAY AND WEAKEN THE OVERALL RIDGE
PATTERN BY THE END OF THE WEEKEND. AS THE RIDGE FLATTENS
OUT...AFTERNOON WEST WINDS WILL INCREASE WHILE TEMPERATURES REMAIN
ABOVE NORMAL IN DRIER CONDITIONS THROUGH THE SHORT TERM.

THERE IS STILL A CHANCE THAT ISOLATED SHOWERS AND THUNDERSTORMS
COULD DEVELOP AS SOME LEFTOVER MOISTURE WILL LINGER OVER MONO AND
MINERAL COUNTIES THIS AFTERNOON. THE NAM STILL SHOWS CAPE VALUES
BETWEEN 200 AND 300 J/KG IN THE AFTERNOON/EVENING IN THE SOUTHERN
ZONES ALONG WITH WINDS INCREASING ALOFT...WHICH COULD SUPPORT
ORGANIZED CONVECTION. THE NAM ALSO INDICATES 100 TO 200 J/KG IN
NORTHERN LASSEN AND WASHOE COUNTIES DUE TO THE WARM AFTERNOON
SURFACE TEMPS. HAVE INCLUDED ISOLATED AFTERNOON THUNDERSTORMS IN
THE NORTHERN ZONES BUT THEY MOST LIKELY DRY AS MOST PRECIPITATION
WILL HAVE EVAPORATED IN THE DRIER LOW LEVELS.

TEMPERATURES WILL ONLY COOL ONE OR TWO DEGREES OVERALL SUNDAY AND
MONDAY...REMAINING ABOVE NORMAL WITH 100+ DEGREE HEAT IN THE
CARSON/HUMBOLDT SINKS. WITH CONTINUED HOT TEMPERATURES ACROSS THE
REGION MODELS ARE CONTINUING TO SHOW AN INCREASED THERMAL GRADIENT
DEVELOPING BETWEEN THE SIERRA AND WESTERN NV WHICH WILL CAUSE
STRONGER ZEPHYR WINDS. THIS IS ESPECIALLY TRUE FOR SUNDAY AS THE
KTRK TO KLOL TEMPERATURE GRADIENT IS NOW ESTIMATED TO BE 18+
DEGREES. HUMIDITY VALUES WILL DROP BELOW 10 PERCENT IN THE
AFTERNOONS AND EXPERIENCE POOR RECOVERIES OVERNIGHT UNDER THE
AFOREMENTIONED DRY SLOT. THE STORY IS THE SAME FOR MONDAY AS
AFTERNOON WEST WINDS INCREASE WITH THE APPROACHING SHORTWAVE.
HOWEVER...CONFIDENCE IS LOWER IN THE WINDS BEING AS STRONG AS
SUNDAY ON MONDAY AFTERNOON AS MODELS ARE NOW BACKING OFF SLIGHTLY
FROM YESTERDAY'S RUN. LABELLE

LONG TERM...TUESDAY THROUGH FRIDAY...

FAIRLY BENIGN WEATHER TO CONTINUE THROUGH THE LONG TERM...WITH HOT
AND DRY CONDITIONS ACROSS THE AREA...AND TYPICAL WASHOE ZEPHYR
ALONG THE SIERRA FRONT IN THE AFTERNOONS AND EVENINGS.

LATEST MED RANGE MODELS CONTINUE TO SHOW A TROUGH MOVING INTO THE
PAC NW...KEEPING THE RIDGE OVER THE SOUTHWESTERN STATES FROM PUSHING
NORTHWARD. THIS WILL KEEP OUR TEMPERATURES FROM WARMING UP TOO
MUCH...WITH GENERALLY MID 90S ACROSS WESTERN NV AND LOW TO MID 80S
IN THE SIERRA. THE HOT TEMPERATURES OVER THE GREAT BASIN WILL KEEP
THE DAILY WEST WINDS EACH AFTERNOON AND EVENING. MODELS HAVE BEEN
SUGGESTING THAT THE THERMAL GRADIENT WOULD BE STRONGEST ON TUE...BUT
LATEST RUNS HAVE REALLY BACKED OFF ON THE GRADIENTS AND WINDS. WINDS
MAY NEED TO BE LOWERED EVEN FURTHER ON TUE IF THIS TREND CONTINUES.

GFS AND ECMWF ARE SUGGESTING A PIECE OF THE TROUGH WILL SPLIT OFF
SOME THE MAIN FLOW AND MOVE DOWN ALONG THE CA COAST ON THU. THIS
WILL KEEP DRY SOUTHWEST FLOW OVER THE REGION INTO THE WEEKEND. DRY
SLOT ALOFT WILL SETTLE INTO THE GREAT BASIN AHEAD OF THIS. POOR
HUMIDITY RECOVERIES AT NIGHT AND SINGLE DIGIT RH'S IN THE AFTERNOONS
WILL NOT BE OUT OF THE QUESTION.  HOON

AVIATION...

VFR CONDITIONS WITH NO MAJOR CONCERNS THROUGH WEEKEND. WINDS ARE
EXPECTED TO INCREASE ON SUNDAY OUT OF THE WEST WITH GUSTS UP TO 35
MPH IN THE AFTERNOON.  HOON

&&

FIRE WEATHER...

A SHORTWAVE MOVING ACROSS THE PACIFIC NORTHWEST
WILL FLATTEN THE RIDGE CURRENTLY OVER THE FORECAST AREA TODAY...
CUTTING OFF THE MOISTURE SOURCE THAT LED TO YESTERDAYS OUTBREAK OF
THUNDERSTORMS. THE BEST CHANCE FOR STORMS TODAY WILL BE ACROSS
MONO AND MINERAL COUNTIES WHERE THE MOISTURE WILL LINGER THE
LONGEST. THERE IS A CHANCE FOR AN ISOLATED DRY THUNDERSTORM UP
NORTH OF SUSANVILLE-GERLACH LATE THIS AFTERNOON.

AS THE RIDGE SLIDES TO THE EAST ON SUNDAY...A PLUME OF VERY DRY
AIR ALOFT WILL MOVE ACROSS NORTHERN CALIFORNIA AND
NEVADA. THIS WILL SET THE STAGE FOR CRITICAL FIRE WEATHER
CONDITIONS ACROSS THE AREA ON SUNDAY AND MONDAY. A FIRE WEATHER
WATCH HAS BEEN ISSUED FOR SUNDAY AFTERNOON AND MONDAY AFTERNOON FOR
AREAS ALONG AND EAST OF HIGHWAY 395.

THE GREATEST CONCERN ON SUNDAY ARE GUSTY WINDS...WITH WESTERLY
WIND ANOMALIES FROM THE GEFS AT 700 MB 2-3 STANDARD DEVIATIONS
ABOVE NORMAL ON SUNDAY AFTERNOON. THESE WINDS WHEN MIXED TO THE
SURFACE COMBINED WITH LOW RH'S COULD CREATE CRITICAL FIRE
CONDITIONS AT MID-SLOPE AND VALLEY LOCATIONS ON SUNDAY AFTERNOON
AND EVENING.

AFTER A NIGHT OF POOR RH RECOVERIES...MONDAY LOOKS TO BE THE BEST CHANCE
FOR CRITICAL FIRE WEATHER CONDITIONS. THE DRY AIR INTRUSION ALOFT
WILL HAVE HAD PLENTY OF TIME TO MIX TO THE SURFACE BY MONDAY...AND
WHEN COMBINED WITH AFTERNOON ZEPHYR WINDS...EXPECT CRITICAL
CONDITIONS TO DEVELOP ON MONDAY AFTERNOON. SREF PROBABILITY OF RH
LESS THAN 15 PERCENT IS GREATER THAN 90 PERCENT ACROSS MUCH OF THE
FIRE WEATHER DISTRICT ON MONDAY. MYRICK/LABELLE/HOON
