RAIN AND MOUNTAIN SNOW RETURNING


..RAIN AND MOUNTAIN SNOW RETURNING TO SOUTHWEST CALIFORNIA SATURDAY NIGHT
INTO SUNDAY NIGHT...

ANOTHER WINTER STORM IS EXPECTED TO IMPACT SOUTHWEST CALIFORNIA
THIS WEEKEND BRINGING RAIN...MOUNTAIN SNOW...AND GUSTY WINDS TO THE
REGION. ON SATURDAY...A NEARLY STATIONARY BAND OF RAINFALL IS EXPECTED
TO AFFECT MONTEREY COUNTY AND POINTS NORTH. IT NOW APPEARS THAT THIS
BAND OF RAINFALL WILL BE SLOW TO TRACK EASTWARD...MOST LIKELY REACHING
THE CENTRAL COAST ON SATURDAY NIGHT. AS THE UPPER LOW PRESSURE
SYSTEM DRAWS CLOSER...RAINFALL IS EXPECTED TO BECOME MORE WIDESPREAD
ACROSS THE REGION SUNDAY INTO SUNDAY EVENING. BY SUNDAY AFTERNOON AND
EVENING...THERE WILL BE SUFFICIENT INSTABILITY FOR A SLIGHT CHANCE
OF THUNDERSTORMS...CAPABLE OF PRODUCING BRIEF HEAVY DOWNPOURS AND
SMALL HAIL.

WHILE THERE IS STILL SOME UNCERTAINTY IN THE EXACT TRACK OF THIS
STORM SYSTEM...THERE IS THE POTENTIAL FOR A GOOD LATE-SEASON
SOAKING. STORM TOTAL RAINFALL ESTIMATES ARE EXPECTED TO RANGE
BETWEEN THREE QUARTERS AND ONE AND ONE HALF INCHES FOR MOST COASTAL AND
VALLEY LOCATIONS. HOWEVER...SOUTHERLY LOW LEVEL FLOW THAT IS EXPECTED
WITH THIS SYSTEM WILL LIKELY BRING GOOD OROGRAPHIC ENHANCEMENT OF RAINFALL
TO THE SOUTH FACING FOOTHILLS AND MOUNTAINS...WHICH COULD SEE TWO TO
FOUR INCH TOTALS.

WHILE THIS SYSTEM IS NOT AS COLD AS LAST WEEKENDS STORM...SIGNIFICANT
SNOWFALL IS POSSIBLE ACROSS THE HIGHER MOUNTAIN ELEVATIONS. THE SNOW
LEVEL IS GENERALLY EXPECTED TO RANGE BETWEEN 5000 AND 5500 FEET ON
SUNDAY...FALLING LOCALLY TO 4500 FEET ON SUNDAY NIGHT. A WINTER STORM
WATCH IS IN EFFECT FOR THE MOUNTAINS OF LOS ANGELES AND VENTURA
COUNTIES...WITH ELEVATIONS ABOVE 5500 FEET POTENTIALLY RECEIVING
BETWEEN 8 AND 16 INCHES OF NEW SNOW ALONG WITH SOUTHERLY WINDS
GUSTING TO 50 MPH. FAVORED LOCATIONS ABOVE 7000 FEET COULD SEE UP TO
20 INCHES OF SNOW. INTERSTATE 5 NEAR THE GRAPEVINE WILL MOSTLY BE
IMPACTED BY STRONG SOUTHERLY WINDS AND RAIN ON SUNDAY...WITH LIGHT SNOW
POSSIBLE ON SUNDAY NIGHT.

RESIDENTS OF SOUTHWEST CALIFORNIA ARE URGED TO STAY TUNED TO THE
LATEST NATIONAL WEATHER SERVICE FORECASTS AND STATEMENTS REGARDING
THIS DEVELOPING WEATHER SITUATION. ANYONE PLANNING TO TRAVEL TO THE
LOCAL MOUNTAINS THIS WEEKEND SHOULD PAY SPECIAL ATTENTION
TO THE LATEST WEATHER FORECASTS AND ROAD CONDITIONS...AND BE PREPARED
FOR THE POSSIBILITY OF DANGEROUS WINTER WEATHER DRIVING CONDITIONS.
