.SHORT TERM /MONDAY/...
-- Changed Discussion --
Continued dry into Monday as sfc high pressure shifts offshore.
Expect increasing mid/high clouds through the day as moisture
increases in the WSW flow aloft, with light southerly sfc flow.

lwr 80s.
-- End Changed Discussion --

&&

.LONG TERM /MONDAY NIGHT THROUGH SATURDAY/...
-- Changed Discussion --
Wet weather expected for a good portion of the long term period
as two upr-level troughs affect the area...one Tue/Wed and the
second Fri/Sat. Isentropic lift increases with a passing warm
front Tue leading to categorical PoPs. The rain may be moderate
to heavy at times as favorable forcing passes directly over the
area. The clouds and rain will keep temps a bit lower Tue than
previous days...highs only in the mid/up 70s. Some drier air
wraps around for Wednesday, but with the upr-level trough
directly over the area rain chances remain in the chance-likely
range. Dry then for Thur as a mid-level ridge traverses the
area. Next upr-level trough moves in late week, but will keep
PoPs no higher than 50% as agreement isn`t high amongst guidance
with the timing as this is still several days out.

.AVIATION /08Z SUNDAY THROUGH THURSDAY/...
VFR conditions expected through the period.

Extended Outlook... Widespread VFR through Monday. Flight
restrictions may occur Monday night into Tuesday with the next
weather system moving in. Improving conditions into Wednesday.

.MARINE...
-- Changed Discussion --
Through Tonight:
A weak surface trough will move across the waters this morning
shifting winds to a west/northwest direction. Wind speeds will
remain modest at best just above ten knots or so. By Monday
morning the pressure pattern remains weak but it seems a bit of
a southerly component begins to develop. Significant seas will
be 1-3 feet.

Monday through Thursday:
One last day of benign marine conditions Mon as broad sfc high
pressure shifts offshore and winds become out of the SSE at ~10
kt in the aftn. Marine conditions then deteriorate by Tue as a
warm front lifts north through the area ahead of the next low
pressure system, with southerly flow increasing to ~20 kt and
seas up to 5-6 ft. SCA conditions are possible and may continue
until late Wed before low pressure to the north pushes offshore
later in the day. Improving marine conditions into Thur as weak
sfc high pressure builds in from the west.
