Synopsis Warm and dry conditions will continue during the
foreseeable future across the interior. Meanwhile, coastal areas
will experience overnight and morning marine clouds through at
least the first half of the work week.

Discussion The synoptic-scale regime across the western half of
the nation is forecast to evolve from early-week west coast
troughing central CONUS ridging to increasingly zonal flow aloft
and a westward shift in the center of a mid-level high. Changes in
sensible weather associated with the evolution in upper-level
heights will mainly be in the form of increasing surface
temperatures... Particularly across interior areas of nwrn ca,
where highs during mid to late week are forecast to increase into
the mid and upper 90s.

In the short-term, surface based cumulus development has occurred
across the trinity and yolla bolly mountains Monday afternoon.

However, model forecast soundings show the presence of a stable
layer centered near 600-500 mb, which should preclude thunderstorm
initiation. Otherwise, stratus has cleared the coast, but short
term model guidance indicates low clouds will redevelop this
evening and persist through much of Tuesday. Patchy drizzle may
occur with stratus in the vicinity of humboldt bay as the marine
layer deepens tonight. Additional bouts of nocturnal coastal
stratus development appear probable during the week, followed by a
period of clearing during the afternoons.

Jmg

Aviation Robust marine stratus clearing has occurred along much
of the coast Monday afternoon. However, short term model guidance
aggressively redevelops widespread low cloudiness this evening.

This will drive ceilings at kcec and kacv back into the ifr-lifr
category, with visibility reductions to 3 sm possible toward
sunrise early Tuesday morning. Elsewhere across interior nwrn ca,
cumulus has developed over the trinity and yolla bolly mountains.

However, the environment is expected to be unfavorable for
thunderstorm development this afternoon evening.

Marine Thinking is relatively unchanged this afternoon with
regards to the marine forecast. The southern outer waters will
continue with persistent small craft advisory conditions through
mid week. Model guidance also indicates some stronger winds are
possible around CAPE mendocino as an expansion jet develops,
leading to gusts to 35 kts near and downwind of the CAPE this
afternoon. Most of the southern inner waters is spared from the
jet therefore have held off on issuing a short term small craft
advisory for the southern inner waters. A tightening surface
pressure gradient will aid in increasing northerlies by mid to
late week across all of the waters, with occasional gusts from 30
to 35 kt possible over the outer waters. In addition, steep
hazardous seas from 9 to 12 feet will be likely over the outer
waters, with seas from 6 to 8 feet expected across the northern
inner waters as well as locations in the vicinity of cape
mendocino. Wci tdj

Ca... None.

Northwest california coastal waters... Small craft advisory until
9 am pdt Wednesday for pzz475.
