|Projected Incident Activity|
12-hour time frame:
Heavier burning fuels may have potential to retain heat and create flare ups. Fire growth will be minimal. Suppression repair efforts are underway in areas of the fire that are no longer posing a potential risk of escape.
24-hour time frame:
Conditions will trend warm and dry allowing finer, smaller fuels to dry. Any heavier fuels with remaining heat will have potential to rekindle and create flare ups. Fire growth will be minimal. Suppression repair efforts are underway in areas of the fire that are no longer posing a potential risk of escape.
An upper level ridge will continue to build into Northern California through early next week and remain in place for much of the upcoming week. This will lead to continued mostly clear skies with temperatures remaining a few degrees above normal through the weekend and into early next week. Humidity should bottom out mainly in the 20s for the next several days with moderate overnight recoveries and mainly terrain and diurnally driven winds.
Humidity peaked by 2300 before midnight on Friday evening and then gradually fell into the 34 to 44% range overnight as winds on the ridges became east to northeast with gusts up to 15 mph before dawn. Skies were mostly sunny today. After a start in the upper 50s to low 60s, temperatures rose into the upper 70s to low 80s. Minimum rh was generally in the 21 to 29% range this afternoon. Winds were east to southeast at 3 to 7 mph on the ridges and down canyon 3 to 6 mph during the morning, with ridgetop winds becoming southwest to west during the midday to afternoon with gusts up to 12 mph. Otherwise winds were upslope or up canyon at 3 to 6 mph during the afternoon with gusts up to 8 mph.
Mostly clear skies are expected as high pressure building in from the Pacific dominants. Humidity recovery tonight will remain in the moderate range, but will be about 8% lower than Thursday night. Wind gusts from the east to northeast up to 14 mph are anticipated on the ridgetops late tonight. Otherwise, highs on Saturday through early next week will again be about 3 to 4 degrees above normal, ranging in the upper 70s to mid 80s. Humidity is expected to bottom out in the 21 to 28% range each afternoon with moderate recoveries each night. Southwest to west ridge winds gusting up to 12 mph are anticipated from midday into the afternoon for the next several days.
