DISCUSSION
THE COLD FRONT THAT BROUGHT A SMALL AMOUNT OF PRECIPITATION TO
THE VALLEY EARLY THIS MORNING IS CONTINUING TO MOVE SOUTHWARD,
LEADING TO STRONG WIND GUSTS IN THE KERN COUNTY MOUNTAINS AND
INTO THE DESERT REGION, AS WELL AS ELEVATED WINDS IN THE VALLEY.
LIGHT SNOW IS EXPECTED TO CONTINUE TO FALL FOR THE TEHACHAPI
MOUNTAINS THROUGH THIS AFTERNOON, WITH 2 INCHES OF SNOWFALL
REPORTED ON HIGHWAY 58 IN THE CITY OF TEHACHAPI EARLIER THIS
MORNING. THERE HAS ALSO BEEN A RAIN/SNOW MIX REPORTED FALLING
ALONG THE GRAPEVINE, WHICH IS ALSO EXPECTED TO CONTINUE THROUGH
THIS AFTERNOON. A WINTER WEATHER ADVISORY IS IN EFFECT FOR BOTH
OF THESE REGIONS UNTIL 4PM THIS AFTERNOON.
AS THE FRONT MOVES FURTHER AWAY FROM THE REGION, THE VALLEY IS
EXPECTED TO CLEAR OUT THIS EVENING AND THAN DENSE FOG IS LIKELY
TO FORM OVERNIGHT AND INTO TOMORROW MORNING DUE TO THE
ADDITIONAL MOISTURE THAT FALL RECENTLY. THE REGION WILL ALSO SEE
THE BUILDING OF A RIDGE AS THE PREVIOUS SYSTEM MOVES EAST. THIS
WILL LEAD TO A MORE STABLE ENVIRONMENT THAT WILL PROMOTE FOG
DEVELOPMENT IN THE VALLEY. THIS RIDGE IS ALSO EXPECTED TO STAY
IN PLACE FOR MULTIPLE DAYS, WHICH INCREASES THE LIKELIHOOD OF
FOG THROUGH NEXT WEEK AS IT HOLDS OVER THE WEST. LONG TERM
FORECASTS ALSO SHOW A DRYING TREND FOR THE REGION THROUGH LAST
JANUARY, AS WELL.
