..DISCUSSION FROM SFOFWFMTR
ELEVATED FIRE WEATHER CONCERNS WILL PERSIST THROUGH THE WEEK,
WITH CRITICAL CONDITIONS POSSIBLE BY THE END OF THE WEEK INTO THE
WEEKEND. THE HIGHEST CONCERNS ARE FOR THE NORTH AND EAST BAYS,
THE DIABLO RANGE, AND THE SANTA LUCIA'S WITH ABOVE NORMAL
TEMPERATURES AND DRY CONDITIONS DURING THE DAY. THE MARINE LAYER
WILL CONTINUE TO BE AROUND 1000FT WITH EXCELLENT RECOVERY WITHIN
IT, HOWEVER FOR LOCATIONS ABOVE 1000FT RECOVERIES WILL CONTINUE TO
BE POOR IN THE 30-40% RANGE. DAYTIME HUMIDITY RECOVERIES WILL BE
POOR ACROSS THE INTERIOR (10-30%) WITH THE DRIEST CONDITIONS
ACROSS THE HIGHER ELEVATIONS (10-20%). THE GUSTY DIURNAL ONSHORE
FLOW WILL PERSIST ALONG COASTAL AREAS, MOUNTAIN GAPS, PASSES AND
RIDGELINES. TEMPERATURES INCREASE FURTHER ON FRIDAY AND INTO THE
WEEKEND, WHICH WILL RESULT IN CONTINUED POOR OVERNIGHT RECOVERIES
FOR HIGHER ELEVATIONS AND LOW DAYTIME RH VALUES ACROSS THE
INTERIOR.
..DISCUSSION FROM SFOFWFEKA
HOT TEMPERATURES ABOVE NORMAL ARE EXPECTED THROUGH THE WEEK INTO
THE WEEKEND WITH WIDESPREAD +100 DEGREE WEATHER ACROSS THE
INTERIOR. LOW AFTERNOON RH IN THE SINGLE DIGITS AND TEENS ARE
FORECAST FOR THE INTERIOR AREAS. OVERNIGHT RECOVERIES WILL BE
MODERATE TO GOOD IN THE LOWER ELEVATIONS AND POOR IN THE HIGHER
ELEVATIONS. WINDS REMAIN RELATIVELY LIGHT THIS WEEK, WITH MORE
TYPICAL AFTERNOON BREEZES AND POTENTIAL STRONGER GUSTS RETURNING
THIS WEEKEND.
