AREA FORECAST DISCUSSION
National Weather Service Eureka CA
352 AM PDT MON JUL 25 2016

.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
depth.

&&

.DISCUSSION...Coastal clouds have spread across the Humboldt, Del
Norte and southern Mendicno coasts this morning. Clouds have also
made their way up the Eel River Valley. Otherwise this morning
skies are clear across the area. These clouds are expected to
push back to the coast this afternoon, but with a very extensive
stratus bank offshore complete clearing is not expected. A weak
shortwave moving into the Pacific Northwest this morning will keep
temperatures in the inland areas nearly steady or a couple degrees
cooler today.

The ridge of high pressure continues to build over the area
and is expected to persist through late in the week. Coastal
clouds will likely be present off and on through the week, but
there is nothing to really indicate that any particular day will
see more or less clouds. Temperatures will peak late in the week
in the interior around 105 in valley locations. A few areas may
reach as high as 110. Late in the week coastal clouds will likely
increase again as the ridge starts to shift east. This may start
to lower temperatures in some of the near coastal areas such as
Ukiah.

Saturday models are showing an upper level trough moving through
the area. This may bring a few showers to the inland area and some
cooler temperatures. There is a slim chance of thunderstorms, but
for now it looks like there is a better chance of just showers
over Trinity county. Sunday and Monday continued cooler
temperatures are expected as models show continued troughiness
over the west coast. MKK

.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. Visibilities and ceilings will improve late
this morning and VFR to MVFR conditions will prevail at KCEC and
KACV this afternoon with light to moderate winds occurring. VFR
conditions and light winds to calm conditions will continue at
KUKI the next few days.

&&

.MARINE...The pressure gradient has weakened slightly allowing
the winds and seas to diminish slightly today. However the
offshore high pressure system combined with the inland thermal low
pressure trough will maintain elevated winds and seas across the
waters most of this week. The higher winds and seas will continue
to be 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 primarily due to short period seas. Gale
warnings will likely be extended across the northern outer waters
through Friday due to increasing offshore winds later this week.

&&

.EKA Watches/Warnings/Advisories...
CA...None.
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.
