SPECIAL WEATHER STATEMENT
Issue Date: 356 PM PST FRI DEC 04 2009
Expiration: 500 AM PST SAT DEC 05 2009

...ACTIVE WEATHER PATTERN LIKELY FOR NEXT WEEK...
A CHANGE IN THE WEATHER PATTERN WITH A STRENGTHENING PACIFIC JET
STREAM WILL BRING STORM SYSTEMS INTO CALIFORNIA AND NEVADA NEXT
WEEK. THE EXACT TIMING AND STRENGTH OF THE STORMS REMAIN
UNCERTAIN HOWEVER CURRENT THINKING IS THAT TWO SEPARATE SYSTEMS
WILL AFFECT THE REGION NEXT WEEK.
THE FIRST SYSTEM WILL BE ACCOMPANIED BY A COLD AIR MASS...BRINGING
SNOW AND SNOW SHOWERS TO EASTERN CALIFORNIA AND WESTERN NEVADA
FROM LATE SUNDAY THROUGH MONDAY. LIGHT TO MODERATE SNOW
ACCUMULATIONS ARE POSSIBLE ACROSS THE EASTERN SIERRA AND PORTIONS
OF WESTERN NEVADA WHICH COULD PRODUCE DIFFICULT DRIVING CONDITIONS
FOR THE MONDAY MORNING COMMUTE. TEMPERATURES IN LOWER ELEVATIONS WILL
LIKELY REMAIN BELOW FREEZING THROUGH MONDAY...AND MAY FALL INTO
THE SINGLE DIGITS MONDAY NIGHT.
A SECOND STORM IS POSSIBLE LATER NEXT WEEK...MAINLY FROM WEDNESDAY
THROUGH FRIDAY. SNOW LEVELS ARE MORE LIKELY TO RISE ABOVE THE
VALLEY FLOOR AS ABUNDANT MOISTURE MOVES INTO THE REGION.
SIGNIFICANT PRECIPITATION AMOUNTS ARE POSSIBLE WITH THIS STORM. WITH
BOTH SYSTEMS...WINDS WILL INCREASE AND BECOME STRONG ESPECIALLY ON
THE SIERRA RIDGES.
IN SUMMARY...SINCE THE EXACT TRACK AND INTENSITY OF THESE STORMS
ARE UNCERTAIN...IT IS TOO SOON TO ESTIMATE POTENTIAL RAIN OR SNOW
AMOUNTS. THE TIMING AND TRACK OF THESE SYSTEMS MAY CHANGE AS NEW
DATA ARE ANALYZED BY NATIONAL WEATHER SERVICE METEOROLOGISTS.
LOCAL OFFICIALS...EMERGENCY MANAGERS AND ANYONE WITH TRAVEL PLANS
NEXT WEEK SHOULD CONTINUE TO MONITOR THE FORECASTS AND FURTHER
STATEMENTS.
