SPECIAL WEATHER STATEMENT
NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
955 PM PST TUE DEC 9 2008

...TURNING MUCH COOLER AND UNSETTLED OVER THE UPCOMING WEEKEND...

RELATIVELY MILD WEATHER FOR THE REST OF THE WORK WEEK WILL BE REPLACED BY MUCH
COOLER AND UNSETTLED WEATHER OVER THE WEEKEND. A SERIES OF LOW PRESSURE AREAS ARE
FORECAST TO DROP SOUTH ALONG THE WEST COAST...WITH THE FIRST ONE REACHING NORTHERN
CALIFORNIA SATURDAY. THIS WILL USHER IN THE COOLING TREND...BUT NOT A GREAT DEAL OF
PRECIPITATION. A SECOND COLDER AND POTENTIALLY WETTER SYSTEM DROPS DOWN THE COAST
SUNDAY...WITH YET ANOTHER MONDAY.

SNOW LEVELS WILL FALL SHARPLY SATURDAY...REACHING WELL INTO THE FOOTHILLS SATURDAY
NIGHT AND SUNDAY. SNOW LEVELS BY SUNDAY COULD
BE AS LOW AS 1500 FEET...AND POSSIBLY AFFECT TRAVEL INTO FOOTHILL AREAS AS WELL AS ANY
MOUNTAIN PASSES.

WHILE IT IS STILL TO EARLY TO SAY FOR CERTAIN THIS WILL OCCUR...EVERYONE SHOULD PAY CLOSE
ATTENTION TO LATER FORECASTS AND STATEMENTS ON THE DEVELOPMENT OF THIS WINTER
WEATHER. IT HAS THE POTENTIAL TO GREATLY AFFECT TRAVEL...NOT ONLY PASSES SUCH AS
I-5 OVER THE GRAPEVINE...BUT COASTAL PASSES AS WELL.

Hopefully this series will end up dumping a fair amount of snow. I returned to Tahoe Wednesday via Hwt 4 and there was very little snow on the ground...even at the pass.

Here's an excerpt from the Tahoe newspaper about the upcoming weather systems.
***************

An intense cold front will move rapidly through the region Friday night and Saturday, according to the National Weather Service in Reno, which has issued a high wind watch. Strong downslope winds are possible along the Eastern Sierra from Reno and Lake Tahoe southward into Mono and Mineral counties.

Meanwhile, the weather service reports the Sierra could fetch between 1 to 2 feet of snow between Saturday and Wednesday.

"We will see decent snowfall accumulations but what you're not going to see is a classic Sierra storm where you get hammered for a day and then it clears out," said Scott McGuire, meteorologist for the weather service. "This storm is not that type of scenario. It wil be a prolonged event through Wednesday."

Southwest winds of 25 to 45 mph with gusts of 60 to 70 mph are possible Friday night into the pre-dawn hours Saturday morning, according to the weather service.
