.DISCUSSION...
PRECIPITATION FROM THE LATEST SYSTEM IS ALREADY MOVING THROUGH OUR
NORTHERN ZONES, AND THE SNOW LEVEL ACROSS THE SOUTHERN CASCADES IS
RANGING FROM 3500 TO 4500 FEET AT THIS TIME. EXPECT THIS SYSTEM TO
MOVE SLOWLY THROUGH THE REGION OVER THE NEXT DAY AND A HALF. SOUTH
WINDS ARE ALREADY QUITE GUSTY...DUE TO A SURFACE PRESSURE GRADIENT
OF 4.7 MILLIBARS FROM THE CAPITAL CITY TO REDDING. REDDING WENT INTO
ADVISORY CRITERIA EARLY, SO HOISTED THAT FLAG JUST AFTER NOON. THE
CENTRAL SACRAMENTO VALLEY, THE SURROUNDING FOOTHILLS AND SOUTHERN
LAKE COUNTY ARE GOING INTO ADVISORY NOW. SNOW ADVISORY CONTINUES
THROUGH THURSDAY MORNING FOR MOUNTAINS OF SHASTA COUNTY INCLUDING
BURNEY BASIN SOUTH TO NORTHERN LAKE COUNTY. TIMING OF SIGNIFICANT
PRECIPITATION INTO THE SIERRA STILL IS A BIT TRICKY...BUT THE
WATCH HAS BEEN TURNED INTO A WARNING STARTING THIS EVENING OVER
THE LASSEN PARK AREA, AND STARTING EARLY THURSDAY MORNING FOR WEST
SLOPES OF THE NORTHERN SIERRA. WARNING CRITERIA SHOULD BE DONE BY
FRIDAY, BUT THE STORM DOOR REMAINS OPEN FOR CONTINUED RAIN AND SNOW
SHOWERS OFF AND ON THROUGHOUT THE EXTENDED PERIODS. RANDY HARTLEY
