.PREVIOUS DISCUSSION... /ISSUED 304 PM PST SAT NOV 22 2014/

SYNOPSIS...

WINDS DIMINISH THIS EVENING IN THE WAKE OF A PASSING STORM SYSTEM
THAT BROUGHT STRONG WINDS AND PERIODS OF RAIN AND HIGH ELEVATION
SNOW TODAY. CONDITIONS BECOME COOLER AND DRIER ON SUNDAY FOLLOWED
BY A SLOW WARMING TREND NEXT WEEK AS HIGH PRESSURE BUILDS OVER
NORTHEAST CALIFORNIA AND WESTERN NEVADA.

SHORT TERM...

ONLY A FEW MINOR ADJUSTMENTS WERE NECESSARY TO THE EXISTING
FORECAST. LOWERED PRECIPITATION CHANCES SLIGHTLY THIS EVENING
WHILE LINGERING WINDS OVER LAKE TAHOE TO AROUND 10 PM. THIS
RESULTED IN THE NEED FOR A LAKE WIND ADVISORY ON TAHOE FOR THIS
EVENING.

OTHERWISE, ADJUSTMENTS WERE BASED ON LATEST MODEL TRENDS BUMPING
TEMPERATURES GENERALLY DOWN BY A DEGREE OR SO OVER THE NEXT FEW
DAYS. THE OVERALL TREND FOR TEMPERATURES IS A LITTLE LOWER FOR
WESTERN NEVADA VALLEYS AS HIGH PRESSURE BUILDS OVER THE
SOUTHWESTERN UNITED STATES STRENGTHENING SURFACE INVERSIONS
THROUGH MID WEEK. WINDS DROP THROUGH THE DAY ON SUNDAY BECOMING
GENERALLY LIGHT OUT OF THE NORTHEAST TO EAST BY MONDAY. HIGHS WILL
BE SEASONABLY COOL SUNDAY AND MONDAY IN THE UPPER 40S TO LOW 50S
BEFORE WARMING INTO THE UPPER 50S ON TUESDAY; SIERRA VALLEY HIGHS
WILL BE AROUND 60 WHERE MIXING WILL BE BETTER. BOYD

LONG TERM...WEDNESDAY THROUGH SATURDAY...

DRY CONDITIONS AND MILD TEMPERATURES WILL PREVAIL OVER THE
THANKSGIVING HOLIDAY AS AN UPPER LEVEL RIDGE BECOMES ESTABLISHED
ACROSS THE GREAT BASIN. LIGHT WINDS AND VALLEY INVERSIONS WILL BE IN
PLACE WED-THU WITH THE RIDGE OVERHEAD WHICH WILL PROMOTE HAZY VALLEY
CONDITIONS WITH TEMPERATURES ACROSS SIERRA VALLEYS VERY NEAR OR A
COUPLE OF DEGREES WARMER THAN WESTERN NEVADA LOCATIONS. OVERALL
EXPECTING HIGH TEMPERATURES TO BE IN THE UPPER 50S TO NEAR 60 REGION
WIDE OVER THE HOLIDAY.

AN UPPER LEVEL LOW WILL BEGIN TO DAMPEN THE RIDGE AS EARLY AS
THURSDAY EVENING AND USHER IN SOME HIGH CLOUDS AHEAD OF IT. MODELS
IN GOOD AGREEMENT IN DEVELOPING THIS LOW BUT DIFFER IN THE TIMING
OF ITS INLAND PROGRESSION. THE EC STALLS THE LOW OFF THE COAST AS
THE UPPER LEVEL FLOW BEGINS TO AMPLIFY WHILE THE GFS BECOMES MORE
PROGRESSIVE AND PROVIDES CHANCES FOR PRECIPITATION AS EARLY AS
FRIDAY AFTERNOON. HAVE MAINTAINED SLIGHT CHANCES FOR PRECIP ALONG
PORTIONS OF NORTHEAST CALIFORNIA FRIDAY WITH CHANCES EXTENDING
ALONG THE SIERRA THROUGH SATURDAY AFTERNOON. OVERALL NOT LOOKING
LIKE AN IMPRESSIVE SYSTEM BUT CONFIDENCE IN DETAILS IS LOW THIS
FAR OUT IN THE FORECAST. FUENTES
