Updated Marine Section

.SYNOPSIS...07/916 AM.

Night through morning low clouds and fog will continue for the
next several days over the coast and valleys with slow, if any,
clearing at the coast. A warming trend will develop for the
weekend and through next week, mainly for inland areas.

&&

.SHORT TERM (TDY-TUE)...07/1213 PM.

No significant changes to the forecast through Tuesday. An upper
low off Central California continues to maintain a deep marine
layer, keeping temperatures on the cooler side. Latest models show
the deep marine layer will continue at least one more day along
with a moderate to strong onshore flow which is typical for this
time of year. By Monday and Tuesday most of the ensemble solutions
show the upper low moving east of the area with a quick pop up
ridge that will boost temperatures early in the week with warmer
valley highs at least reaching the lower 90s and around 100
across the Antelope Valley. Coastal areas will continue to be
influenced by a shallower but still present marine layer and still
moderate to strong onshore flow, keeping coastal highs in the 60s
to lower 70s. Gusty southwest winds will be a daily occurrence
across the AV in additional to gusty northwest winds across
southwest Santa Barbara County in the late afternoon and evening.

.LONG TERM (WED-SAT)...07/1223 PM.

A cooling trend will begin Wednesday as a series of weak troughs
move through the Pac NW and northern California. Moderate to
strong onshore flow will persist and with the shift to a trough
pattern temperatures will drop 3-5 degrees each day through
Friday, bringing highs back down below normal as early as Thursday
and lasting into next weekend. Low clouds and fog will push back
into the valleys with slow afternoon clearing.The daily gusty
wind pattern will continue across the AV and southwest Santa
Barbara County. Overall a very typical June weather pattern.
