DISCUSSION
FOG CONTINUES TO DOMINATE THE FORECAST DISCUSSION AND WILL FOR
THE FORESEEABLE FUTURE. VISIBILITY IN THE SAN JOAQUIN VALLEY
WILL FALL TO LESS THAN A QUARTER MILE DURING THE EARLY MORNING
HOURS IN SOME AREAS; WITH WIDESPREAD VISIBILITIES BELOW ONE
MILE. WITH LITTLE IN THE WAY OF STEERING FLOW, PATCHY AREAS OF
REDUCED VISIBILITIES WILL LINGER INTO THE AFTERNOON. A FEW SNOW
FLURRIES ARE POSSIBLE THIS AFTERNOON IN THE MOUNTAINS, BUT
SIGNIFICANT ACCUMULATION IS NOT EXPECTED.
A LOOK INTO THE LONG TERM FORECAST SHOWS LITTLE IN THE WAY OF
CHANGES. WE'LL SETTLE INTO ANOTHER STABLE PATTERN THAT WILL CONTINUE
TO KEEP FOG IN PLACE FOR MUCH OF THE VALLEY INTO THE MIDDLE OF NEXT
WEEK. A WEAK TROUGH IN THE UPPER LEVEL FLOW MAY BRING SOME SHOWERS
INTO THE AREA BUT IT IS UNLIKELY TO BRING THE CHANGE IN ATMOSPHERE
WE'D NEED TO BREAK OUT OF THIS PATTERN.
HIGH TEMPERATURES WILL BE IN THE MID 50S FOR MOST OF THE CWA THE
REMAINDER OF THE WEEK AND INTO THE WEEKEND, WITH LOWS PLEASANTLY IN
THE LOW TO MID 40S EXCEPT AT HIGHER ELEVATIONS IN THE MOUNTAINS.

MVFR AND POSSIBLY EVEN VFR CONDITIONS FOR A FEW HOURS AFTER 20Z.
