A pair of blustery, soaking storms will stream into Northern California beginning Friday, bringing as much as 10 inches of rain south and east of the Bay Area by Christmas Day and setting up potentially difficult travel conditions for those escaping for the holidays.
Though computer weather models differ on the exact trajectory and strength of the two separate weather systems, meteorologists are bracing for sizable amounts of rain and the possibility that some rivers might overrun their banks.
"No matter how you slice it, it's going to be a significant weather event," said Rob Hartman, lead hydrologist with the National Weather Service's California-Nevada River Forecast Center. "If it comes in heavy and warm, it will be a bigger flood event. But the real wild card is the freezing level."

Big storm expected to hit Bay Area this afternoon
http://www.sfgate.com/cgi-bin/article.cgi?f=/c/a/2010/12/28/BA2G1H0J3M.DTL
San Francisco — High winds and heavy rain are expected to buffet Bay Area commuters this afternoon.
Heavy rain and gusts as high as 45 miles per hour will likely start between 4 and 6 p.m. and continue for two or three hours, said Austin Cross, a meteorologist with the National Weather Service.
“It could be particularly nasty with the evening commute,” he said.

...WINTER STORM TO IMPACT SOUTHWEST CALIFORNIA LATE TONIGHT AND WEDNESDAY FOLLOWED BY VERY COLD WEATHER...
A STRONG STORM APPROACHING FROM THE NORTHWEST WILL MOVE THROUGH LATE TONIGHT AND WEDNESDAY MORNING WITH SHOWERS LINGERING THROUGH WEDNESDAY EVENING. THIS FAST MOVING SYSTEM SHOULD TAP INTO DEEP MOISTURE RESULTING IN A PERIOD OF MODERATE TO HEAVY PRECIPITATION WITH THE FRONTAL PASSAGE WEDNESDAY MORNING.
RAINFALL TOTALS SHOULD RANGE FROM ABOUT A THIRD TO TWO THIRDS OF AN INCH IN THE COASTAL AND VALLEYS AREAS WITH NEAR AN INCH ON THE COASTAL MOUNTAIN SLOPES. HOWEVER...THERE COULD BE LOCAL LARGER AMOUNTS ON THE SOUTHWEST FACING SLOPES OF THE SAN BERNARDINO COUNTY MOUNTAINS. THE HIGH DESERTS SHOULD GET UP TO HALF AN INCH OF RAIN WITH LESS THAN A QUARTER OF AN INCH IN THE LOWER DESERTS.
THE ADDITIONAL RAINFALL WILL CAUSE RAPID RUNOFF AND FLOODING DUE TO NEARLY SATURATED GROUND FROM RECENT RAIN. THIS COULD RESULT IN FLOODING OF LOW LYING AREAS. THERE COULD BE DEBRIS FLOWS IN AND BELOW RECENTLY BURNED AREAS AS WELL AS ROCK AND MUD SLIDES ON STEEP TERRAIN...AND FURTHER EROSION OF RAIN SOAKED HILLSIDES.
THE SNOW LEVEL WILL BE NEAR 7000 FEET THROUGH MOST OF THE STORM...THEN FALL TO 6000 FEET BY WEDNESDAY AFTERNOON AND TO 3000 FEET OR LOWER WITH A FEW LINGERING SHOWERS. HOWEVER...MOST OF THE WIDESPREAD SIGNIFICANT PRECIPITATION WILL BE OVER BY THE TIME THE SNOW LEVEL LOWERS...AND ANY SNOWFALL ACCUMULATIONS WILL BE VERY SMALL BELOW 5000 FEET.
SAN BERNARDINO COUNTY MOUNTAIN RESORT LEVELS AND THE HIGHER RIVERSIDE COUNTY MOUNTAINS SHOULD RECEIVE ABOUT 3 TO 8 INCHES OF SNOW. HOWEVER...ABOVE 7000 FEET MORE THAN A FOOT OF SNOW CAN BE EXPECTED. THE HIGHER SAN DIEGO COUNTY MOUNTAINS COULD GET AN INCH OR TWO OF SNOW. COLD AIR DAMMING ON THE NORTH SIDE OF THE SAN BERNARDINO MOUNTAINS COULD RESULT IN SNOW FLURRIES IN THE HIGH DESERTS AS WELL WEDNESDAY NIGHT.
STRONG GUSTY WEST TO NORTHWEST WINDS WILL ACCOMPANY THIS SYSTEM...BECOMING EVEN STRONGER BEHIND THE FRONT WEDNESDAY NIGHT. THE STRONGEST WINDS WILL BE IN THE MOUNTAINS AND HIGH DESERTS WHERE THERE COULD BE WIND GUSTS OVER 65 MPH. THESE WINDS COULD CAUSE BROKEN TREE LIMBS...DOWNED TREES AND DOWNED POWER LINES. NEAR ZERO VISIBILITY WILL BE POSSIBLE AT TIMES DUE TO SNOW AND BLOWING SNOW.
DRY COLD NORTHWEST FLOW ALOFT WILL BRING TEMPERATURES ABOUT 10 TO 20 DEGREES BELOW SEASONAL AVERAGES THURSDAY AND FRIDAY. THERE WILL LIKELY BE WIDESPREAD FROST IN THE INLAND VALLEYS THURSDAY AND FRIDAY NIGHTS.
PEOPLE TRAVELING LATE TUESDAY AND WEDNESDAY SHOULD CLOSELY MONITOR THE LATEST NATIONAL WEATHER SERVICE FORECASTS AND STATEMENTS AND PLAN ACCORDINGLY. THE RAIN WILL CAUSE SLICK ROADS AND MOTORISTS SHOULD USE EXTRA CAUTION. DO NOT DRIVE THROUGH FLOODED AREAS OR AROUND BARRICADES. IF TRAVELING INTO THE MOUNTAINS...BE PREPARED FOR THE POSSIBILITY OF WINTER STORM CONDITIONS WITH VERY LOW WIND CHILL TEMPERATURES.

California snowpack is deepest for December in 17 years
http://www.mercurynews.com/science/ci_16960361?source=rss
Blessed with a brilliant blanket of early winter snow, California’s snowpack is double its average for this time of year — and the deepest it’s been in 17 years.
...
Water content in California’s mountain snowpack measured at 198 percent of the average for this time of year. So much snow has fallen that the state has already accumulated 65 percent of the average water content for the entire winter season.

It’s blowing and raining pretty good here..
Thanks for the link....looks like a nice snowpack.

This is just a run of the mill rain storm but it serves the purpose of prepping the weather for a real blizzard on the easter slope of the Rockys...
