.SYNOPSIS...Strong high pressure will bring a significant warming
trend into the coming week with temperatures approaching the
triple digits across the interior. Coastal areas will continue to
see a mix of clouds and sun as the marine layer fluctuates in


.DISCUSSION...Pics from space this morning showing the stubborn
ribbon of stratus along the north coast which was the same cloud
pattern that was seen last night at this time. Thus with the same
weather conditions expected again later this morning...the north
coast should see general clearing by late morning. The Mendo coast
appears to be generally clear early this morning so another nice
day on tap there. Temperatures across the interior are once again
expected to reach into the 100s over valley and drainage locations
this afternoon while afternoon temperatures along the coast will
liekly get into the mid 60s again under a mix sun and clouds. High
pressure aloft will gradually build over the desert SW over the
next few days, with high temperatures at many interior locations
exceeding 100 degrees for the next 3-5 days. A few high valley
spots may see readings reach 110 by mid to late in the coming week
with 500 MB heights building to near 597 dam as close as the NV/UT
border. Rain chances appear scant over the next week. Have left in
some silent PoPs over portions of the interior for Friday and
Saturday afternoons. However, models appear to be keeping most of
the monsoonal moisture bottled up well south of the area, and GFS
instability parameters look meager. /SEC/JT


.AVIATION...VFR TO IFR conditions and light winds to calm conditions will
continue at KCEC and KACV this morning. The lower conditions will be due to
stratus and patchy fog reducing ceilings and/or visibilities. VFR conditions
will prevail at KCEC and KACV this afternoon with light to moderate winds.
VFR conditions and light winds to calm conditions will continue at KUKI the 
next few days.


.MARINE...An offshore high pressure system interacting with an inland thermal
low pressure trough has tightened the pressure gradient and subsequently
increased the winds and seas across the waters. Elevated winds and seas will
persist across the waters through the middle of this week. Winds and seas will
be higher across the outer waters. Gale warnings will continue across the outer
waters through early Wednesday morning. Small craft advisories will continue
across the near shore waters through Wednesday afternoon.


.EKA Watches/Warnings/Advisories...
NORTHWEST CALIFORNIA COASTAL WATERS...Small Craft Advisory until 2 PM PDT Wednesday for PZZ450-455.

     Gale Warning until 3 AM PDT Wednesday for PZZ470-475.
