...Discussion from Monterey...

Onshore flow and a returning marine layer will bring moderate to
excellent humidity recoveries tonight. Thursday will feature onshore
flow with higher daytime humidities, but also slightly higher
temperatures inland. High pressure will gradually build over the
district Friday and into next weekend kicking off a marked warming
and drying trend.



...Discussion from Los Angeles/Oxnard...

...LONG DURATION HOT AND MODERATE DRY CONDITIONS POSSIBLE STARTING THIS
WEEKEND...

Improved conditions will continue through Thursday or Friday. The
marine layer will moderate coastal and valley areas, most expansive
today and less so Thursday and Friday. Southwest Santa Barbara
County will continue to see Sundowner wind gusts between 35 and
45 mph through Thursday Night, but humidities will remain above
25 percent. Mountain,  interior valleys, and deserts will remain dry
and breezy but much  improved from earlier this week. Southwest to
northwest wind gusts will  peak between 20 and 30 mph with minimum
humidities generally between 10  and 20 percent. With ample dead
fuels and dried grasses, the risk for  large grass fires will remain
elevated.

High pressure will build once again this weekend. Hot and dry
conditions will return with the potential of a long duration event
lasting through most of next week and beyond. High temperatures
between 95 and 105 will be common from the warmest coastal valleys
to the interior areas. Minimum humidities over the mountains and
interior areas between 8 and 15 percent will be common with warm
nights. Gusty winds from typical  diurnal directions will form each
day, with weak to moderate Sundowner  and I-5 Corridor winds
expected starting Monday. The one wrinkle will be from Saturday
Night through Tuesday, there is a growing potential a  monsoonal
surge with a threat of thunderstorms and lightning fire  starts.
Humidities will be higher during this period as well, with a low but
present through for brief heavy downpours.
