CA OVERNIGHT. SPOTTER REPORTS OF ACCUMULATING SN IN EASTERN
VALLEYS IN TRINITY COUNTY WITH LEVELS DOWN TO 2000-2500 FT. NSSL
SNOW LEVEL AND MODELED DATA SUGGEST SNOW LEVELS AROUND 4500 FT
AREA WIDE...HOWEVER...SPOTTER REPORTS AND TRINITY CTR WEB CAM
IMAGES SHOW ACCUMULATIONS AROUND 2 INCHES THIS AFTERNOON.
THEREFORE...ELECTED TO LOWER WINTER WX ADVISORY OVER TRINITY
COUNTY TO 2KFT THROUGH 12Z. ADDITIONALLY...WINDS BEGINNING TO
INCREASE THIS AFTERNOON WITH REPORTS OF GUSTS TO 45 MPH. ALTHOUGH
SOME GUSTS MAY REACH ADVISORY LEVEL...DO NOT THINK SUFFICIENT
AREAL COVERAGE WILL BE REACHED TO WARRANT A WIND ADVISORY. EXPECT
FRONT TO PUSH ACROSS CWA FROM 03-09Z TONIGHT WITH S WINDS AND
PRECIP PEAKING IMMEDIATELY AHEAD OF THE BOUNDARY. COLD AIR WILL
FILTER INTO CWA BEHIND THE FRONT WITH SNOW LEVELS PLUMMETING TO
1500 FT. PRECIP WILL TRANSITION TO SHOWERS BEHIND THE FRONT WITH

SLOWLY DECAY INTO THE WEEKEND. MODELS VARY IN POSITIONING OF THE
NEXT SYSTEM FOR THE WEEKEND, SO CONFIDENCE REMAINS LOW TO MODERATE
