DISCUSSION
MID-LEVEL AND HIGH CLOUDS ARE CURRENTLY PASSING OVER THE REGION
AHEAD OF AN UPPER-LEVEL LOW OFFSHORE. THIS LOW WILL TRACK
SOUTHWARD OFFSHORE DURING THURSDAY INTO FRIDAY AND WILL PROVIDE
LITTLE IN THE WAY OF PRECIPITATION. THE BEST CHANCES WILL BE
OVER THE SIERRA NEVADA AND KERN COUNTY MOUNTAINS (20-30
PERCENT), ALTHOUGH THERE IS A 20 PERCENT CHANCE INTO BAKERSFIELD
DURING LATE THURSDAY. PRECIPITATION WILL BE LIGHT, OR BELOW ONE
TENTH OF AN INCH OF LIQUID AND MAINLY A DUSTING UP TO AN INCH
OF SNOW ABOVE 7,000 FEET DURING THURSDAY AFTERNOON UNTIL FRIDAY
EVENING. ALTHOUGH, THE CHANCE FOR ONE INCH OF SNOW IS ABOUT
10-20 PERCENT DURING THE PERIOD. VALLEY FOG WILL BE LESS
WIDESPREAD FOR TONIGHT AND THURSDAY NIGHT, BUT WE CAN'T RULE OUT
AT LEAST SOME PATCHY DENSE FOG BY EARLY THURSDAY MORNING AND
AGAIN LATE THURSDAY NIGHT INTO FRIDAY.
FOR THE WEEKEND AND NEXT WEEK, THE RIDGE OF HIGH PRESSURE
RETURNS AND WILL BRING RENEWED CHANCES FOR MORE WIDESPREAD DENSE
FOG IN THE SAN JOAQUIN VALLEY. OTHERWISE, DRY CONDITIONS WITH
ABOVE AVERAGE TEMPERATURES, THOUGH GENERALLY MILD, WILL
PREVAIL.
