...POTENTIAL FOR WINTER STORMS TO INCREASE NEXT WEEK...
THE JET STREAM OVER THE PACIFIC IS EXPECTED TO STRENGTHEN NEXT
WEEK LEADING TO INCREASED TRANSPORT OF SUBTROPICAL MOISTURE INTO
THE REGION. CHANCES FOR WINTER STORMS WILL INCREASE AS A RESULT.
WHILE THERE REMAINS A HIGH DEGREE OF UNCERTAINTY REGARDING THE
EXACT TIMING AND LOCATION OF ANY STORMS, OUR LATEST FORECAST IS
ANTICIPATING TWO SYSTEMS TO AFFECT THE REGION NEXT WEEK.
THE FIRST WOULD BE ASSOCIATED WITH A STRONG COLD FRONT EARLY IN
THE WEEK, ROUGHLY SUNDAY NIGHT OR MONDAY. SNOW LEVELS WITH THIS
SYSTEM WILL DROP TO THE VALLEY FLOORS. A SECOND, WARMER, STORM IS
POSSIBLE LATER IN THE WEEK, SOMETIME BETWEEN WEDNESDAY AND FRIDAY.
SNOW LEVELS WOULD BE HIGHER WITH THIS STORM. WITH BOTH SYSTEMS,
WINDS WILL INCREASE AND BECOME STRONG ESPECIALLY ON THE SIERRA
RIDGES.
AGAIN, UNCERTAINTY IN THE DETAILS REMAINS HIGH AND IT IS TOO SOON
TO ESTIMATE POTENTIAL RAIN/SNOW AMOUNTS. THE TIMING AND TRACK OF
THESE SYSTEMS MAY CHANGE AS NEW DATA ARE ANALYZED BY NATIONAL
WEATHER SERVICE METEOROLOGISTS. PEOPLE, INCLUDING LOCAL
OFFICIALS, EMERGENCY MANAGERS, AND ANYONE WITH TRAVEL PLANS NEXT
WEEK, SHOULD CONTINUE TO MONITOR THE FORECASTS FOR FURTHER
STATEMENTS.
