.SYNOPSIS...
Issued at 1134 AM PDT Sun May 5 2024

Conditions clearing out today in the wake of yesterday`s front.
Cool weather to kick off the week, but a notable warm up is on the
way for the latter half of the week into this weekend.

.SHORT TERM...
(This afternoon through Monday)
Issued at 1134 AM PDT Sun May 5 2024

Visible satellite showing ample clearing across much of the area
in the wake of the cold front yesterday. Some isolated cumulus
continue to form over complex terrain areas as a result of
daytime heating and a hint of lingering low level instability.
However, don`t expect much in the way of additional precip in
these areas. There is still a bit of a hindrance in the form of
some capping stability in the low to mid levels. Some areas in the
highest peaks of the Santa Lucia and Santa Cruz Mtns can`t rule
out a sprinkle or two this afternoon, but anything outside of that
seems to be a very low chance. The weather remains quiet into
Monday with clear and dry conditions. Overnight temperatures into
Monday morning will be on the chilly side once again, similar to
last night, but we will warm up from here.

.LONG TERM...
(Monday night through next Saturday)
Issued at 1134 AM PDT Sun May 5 2024

Beyond Monday, the pattern shifts to become dominated by a
longwave ridge settling in over the Western US. The region will
remain dry through the rest of the week with temperatures
gradually heating up into the weekend. As it stands, Thursday and
Friday look to be the warmest as afternoon highs are forecast to
rise into the mid-80s across inland valleys and 70s elsewhere.
Once again, with temps above seasonal averages by the end of the
week and coming off the heels of an anomalously cold system, it is
important to remind ourselves that these quick changes in
temperatures can still result in heat-related illness, even with
highs in the 80s. As a result, much of our area below about 3500
feet and off the immediate coast will be under a minor Heat Risk
Wednesday into the weekend. This primarily affects individuals who
are extremely sensitive to heat, especially when outdoors without
effective means of cooling or adequate hydration.

In the longer term, any chance for rain is dismal as we inch
closer to our typical summertime pattern, and a there is a slight
chance that above normal temperatures persist into the following
week.

(00Z TAFS)
Issued at 428 PM PDT Sun May 5 2024

VFR through the TAF period for all terminals, with the biggest
concern will be the winds. Post frontal W/NW winds remain breezy

gusty and breezy with >30 knot winds, but little to no concerns for
AWW at the moment. Winds will becoming moderate overnight but will
rebuild to breezy by Monday afternoon.

.MARINE...
(Tonight through next Friday)
Issued at 428 PM PDT Sun May 5 2024

Dry weather prevails through the forecast period as high pressure
builds and moves eastward. Moderate northwesterly winds with the
occasional fresh gust prevail into Monday. Beginning Tuesday night
and continuing into Thursday, winds will become more northerly
and strengthen with near gale force sustained winds and high end
gale force gusts possible. Significant wave heights will build
beginning Tuesday with wave heights between 12 to 15 feet
possible by mid-week. Strong winds and elevated wave heights will
combine to create dangerous conditions for small crafts Tuesday
through the end of the work week.
