..DISCUSSION FROM SFOFWFMTR
...NEAR CRITICAL FIRE WEATHER CONDITIONS THROUGH FRIDAY ACROSS
MONTEREY AND SAN BENITO COUNTIES DUE TO WARM AND VERY DRY
CONDITIONS EACH NIGHT AND DAY WITH LITTLE TO NO OVERNIGHT RH
RECOVERY...
A ROBUST, YET SHALLOW MARINE LAYER REMAINS IN PLACE WITH GOOD TO
EXCELLENT OVERNIGHT RECOVERIES EXPECTED THROUGH FRIDAY IN THE
LOWER ELEVATIONS. HOWEVER, IN THE HIGHER ELEVATIONS OF THE BAY
AREA AND CENTRAL COAST WILL SEE POOR OVERNIGHT RECOVERIES AND
DAYTIME RETENTIONS THROUGH LATE WEEK. WARM AND VERY DRY CONDITIONS
WILL PERSIST ABOVE THE MARINE LAYER, INCLUDING THE AREA IMPACTED
BY THE TIMBER FIRE. ONSHORE WINDS INCREASE SLIGHTLY AS A TROUGH
DEVELOPS OFF OF THE WEST COAST AND BRINGS A COOLING TREND THROUGH
THE UPCOMING WEEKEND AND INTO EARLY NEXT WEEK.
..DISCUSSION FROM SFOFWFEKA
THE CURRENT WEAK RIDGING PATTERN WILL GIVE WAY TO A WEAK
TROUGHING REGIME, BRINGING COOLER TEMPERATURES AND HELPING
RECOVERY RH VALUES OVERNIGHT. MINIMUM DAYTIME RH VALUES WILL ALSO
IMPROVE. TRINITY AND LAKE COUNTIES WILL STILL HAVE MINIMUM RH
VALUES IN THE UPPER TEENS TO 20'S TUESDAY BUT WILL CONTINUE TO
IMPROVE AS THE WORK WEEK PROGRESSES AND THE OFFSHORE LOW PRESSURE
SYSTEM APPROACHES BC AND WASHINGTON COAST, BRINGING MOISTURE INTO
THE AREA ALBEIT SLIGHT. THE MARINE LAYER DEEPENS AND WILL ALSO
MODERATE TEMPERATURES AND TAMP DOWN FIRE WEATHER CONDITIONS. WINDS
WILL GENERALLY REMAIN LIGHT AND TERRAIN DRIVEN, ASIDE FROM
SOUTHWESTERLY AFTERNOON BREEZES.
