DISCUSSION
CURRENT SATELLITE IMAGERY SHOWS CUMULUS CLOUDS STARTING TO BUBBLE
UP, MAINLY SOUTH OF US-50 THIS AFTERNOON. THIS WILL BE THE BEST
AREA FOR SHOWER AND THUNDERSTORM DEVELOPMENT, WITH THE HIGHEST
CHANCES FOR THUNDERSTORMS ALONG THE HIGHER TERRAIN (15-20% CHANCE).
STORMS THAT DEVELOP TODAY, MAINLY AFTER 4PM, WILL BE CAPABLE OF
BRIEF HEAVY RAIN AND PELLET SHOWERS.
THE LONGWAVE TROUGH PATTERN THAT WE'RE IN FOR THE NEXT WEEK WILL
SHUTTLE IN SNOW CHANCES ABOVE 8000' SATURDAY NIGHT FOR ALPINE
COUNTY AND SOUTHWARD. SNOW LEVELS DROP TO 6000' SUNDAY MORNING,
WHICH WILL BRING SLICK MOUNTAIN ROADS. SNOWFALL ACCUMULATIONS ARE
6 INCHES AT BEST ALONG THE HIGHEST TERRAIN, WITH A 20-30% CHANCE
FOR 1 INCH OR MORE OF SNOW ALONG US-395 BY SUNDAY MORNING. SNOW
THAT ACCUMULATES ON ROADWAYS WILL MELT OFF AS THE SUN RISES SO
TRAVEL DELAYS WILL BE SHORT-LIVED.
WINDS WILL BE ENHANCED SATURDAY AND SUNDAY DUE TO THE PASSAGE OF
THE SHORTWAVE TROUGH, WITH GUSTS UP TO 30 MPH OVERNIGHT. RIDGETOP
GUSTS MAY REACH UP TO 50 MPH. SUNDAY WILL ALSO BE THE COLDEST DAY
OF THE WEEK, WITH HIGHS IN THE UPPER 50S/LOW 60S FOR VALLEYS AND
MID 40S FOR SIERRA COMMUNITIES. THE LONGWAVE TROUGH PATTERN WILL
KEEP DAILY SHOWER CHANCES THROUGH AT LEAST WEDNESDAY, WITH 10-15%
CHANCE FOR THUNDER. A WARMING TREND WILL ALSO ACCOMPANY THIS, WITH
HIGHS BACK UP TO THE LOW 70S (VALLEYS) AND LOW 60S (SIERRA) BY
WEDNESDAY.
