DISCUSSION
DESPITE THE CUTOFF LOW SPINNING MUCH CLOSER TO THE COAST, WE
WOKE UP TO DENSE FOG THIS MORNING AS THERE WAS NOT A LOT OF
MIXING. HOWEVER, THE RADAR IS PICKING UP VERY LIGHT SHOWERS OVER
THE TEHACHAPI MOUNTAINS, EASTERN KERN COUNTY, AND PORTIONS OF
THE SOUTHERN SAN JOAQUIN VALLEY THIS MORNING. DRY CONDITIONS
WILL PREVAIL IN THE VALLEY THIS AFTERNOON AS THE LOW SLIDES
INLAND LATER TODAY THROUGH TOMORROW. THE SIERRA NEVADA STILL HAS
A 50 TO 70 PERCENT CHANCE OF ANY SNOW ACCUMULATION ABOVE 7,000
FEET THROUGH FRIDAY AFTERNOON.
DENSE FOG IS EXPECTED AGAIN TONIGHT AS THE MODELS HAVE A 50 TO
70 PERCENT CHANCE OF VISIBILITIES AT OR BELOW QUARTER MILE
BETWEEN MIDNIGHT AND 11 AM FRIDAY. THE DENSE FOG WILL CONTINUE
THROUGH THE WEEKEND INTO NEXT WEEK AS A WEAK RIDGE MOVES IN OVER
THE WEEKEND KEEPING US DRY STILL. HOWEVER, THE ENSEMBLES HINT AT
A TROUGH SLIDING JUST NORTH OF CALIFORNIA WEDNESDAY INTO
THURSDAY OF NEXT WEEK WITH A 20 TO 25 PERCENT CHANCE OF ANY RAIN
ACCUMULATION IN THE SAN JOAQUIN VALLEY. KEEPING THIS IN MIND,
THE CPC KEEPS US AT A 50 TO 70 PERCENT CHANCE OF ABOVE AVERAGE
TEMPERATURES IN THE 6-10 AND 8-14 DAY OUTLOOK. HOWEVER, THE CPC
ALSO SHOWS A 33 TO 40 PERCENT CHANCE OF BELOW AVERAGE
PRECIPITATION IN THE 6 TO 10 DAY OUTLOOK AND NEAR NORMAL
PRECIPITATION IN THE 8 TO 14 DAY OUTLOOK.
