AREA FORECAST DISCUSSION

.SYNOPSIS...Interior temperatures forecast to diminish each day
through Friday. Coastal stratus coverage becoming less through the
week with clear skies possible Friday afternoon. Stronger winds are
to be expected through the rest of the week into the weekend.

.DISCUSSION...

Key Messages:
* Interior heat risk diminishing and becoming low for the remainder
  of this week.

* Gustier westerly and northwesterly breezes in the interior valleys
  each afternoon and evening Wednesday through Saturday.

* Strengthening coastal northerlies mid to late week.


An upper upper level trough swings over our area from the north
through the rest of the week. This synoptic weather will bring a
general cooldown to our temperatures through the weekend. Inland
valleys will struggle to break 90F on Wednesday through the rest of
the week and weekend. High tempertures look to be around the low 80s
at the warmest for inland valleys Friday and Saturday as of right
now. This comes a relief after what has been a warm couple of weeks
to start meteorological summer. These cooler temperatures will also
be accompanied by stronger winds with afternoon wind gusts around 15-
20mph in the later portion of the week.

This week, an upper level trough will impact the PacNW with possible
rain. While most of the rain potential lies be out of our area and
focused mostly in Oregon and Washington, there is a low, 10-20%
chance that Del Norte and Northern Humboldt could receive some
precipitation accumulation over 0.02" of rain through Monday.
While these numbers are not astonishing, this is a notable change
in weather compared to our typical summer pattern.

.AVIATION...A persistent marine layer has continued to blanket the
coast, though a robust upper level short wave approaching the coast
has helped lift ceilings to generally IFR conditions with good
visibility at the surface. Light drizzle is likely throughout the
night with some sporadic drops to LIFR visibilities in the early
morning hours. Ceilings will most likely gradually break through the
day Wednesday with at least some period of VFR conditions (60%
chance) all along the coast in the late afternoon. Otherwise VFR
conditions will persist for the interior. /JHW

.MARINE...Winds will continue to gradually increase across the outer
waters through the work week. Locally near gale to gale force wind
gusts are forecast to develop leeward of Cape Mendocino Wednesday
afternoon. Widespread fresh to strong northerly breezes with some
near gale force gusts downwind of Cape Mendocino begins on Thursday
and then continues into the weekend as the high pressure stalls over
the eastern Pacific and the pressure gradient tightens up along the
coast.

Mid period northwest swell will continue to dominate the sea state
through mid week. In addition, a long period southwest swell of 3-4
feet at 17 seconds will slowly subside through Thursday. This could
present a small sneaker wave threat on south facing beaches if it
ends up coming in this big. Wind driven seas are expected to
increase on Thursday and Friday.
