Synopsis Dry conditions will continue through early next week,
with degraded air quality due to wildfire smoke. Rain is finally
expected to arrive during the middle of the week, and is likely to
continue periodically through the end of the weekend.

Discussion Generally mild and dry conditions continue to
persist throughout the region today, with a continuation of poor
air quality in some areas due to lingering wildfire smoke.

Unfortunately, a gradual shift to a light south-southeasterly
wind flow regime is likely to result in a continuation of this
smoke for the next few days, perhaps even becoming slightly worse
at times. Otherwise though, mild conditions with mostly-cloud free
skies can be expected for the remainder of the weekend and early
next week across interior areas, with chilly overnight low
temperatures that may drop below freezing. Along the coast,
typical cool conditions will prevail, with overnight bouts of very
shallow stratus and fog.

By mid-week, confidence continues to increase regarding a
wholesale pattern change for the west coast, which is expected to
bring the most significant rainfall thus far this season. While
there remains a considerable amount of uncertainty regarding the
day to day timing details and total accumulations, it appears
likely that multiple rounds of rainfall can be expected between
late Tuesday night and Sunday. While the exact totals are a bit
uncertain given the uncertainty in how long this event will last,
it does appear that this rain is very likely to be of the
beneficial variety, and not enough to result in significant
hazards aside from the typical rocks on mountain roads, moderate
river rises, and locally slippery driving conditions made worse by
accumulated oil on road surfaces.

Aviation high cloudiness should clear this evening, allowing
for the potential of patchy mist and fog development along the
coast later tonight and into early tomorrow morning. This upper
level clearing is brief however, and the high clouds should return
again by tomorrow morning. This could inhibit the dissipation of
any mist or fog that may have formed overnight for a few extra
hours into the morning. Interior areas continue to be impacted by
smoke and haze this afternoon, resulting in moderately restricted
visibilities. Experimental smoke model guidance for the interior
area shows the smoke thinning tonight, however it should still
marginally impact visibilities through tomorrow. Tdj

Marine Light winds and low seas are expected through Tue as a
weak front forces a ridge axis over the coastal waters. There
will be a messy set of small swell groups as well as shorter
period wind waves that will combine to produce seas generally
around 5 ft or less. The main components, after the northerly wind
waves subside, appears to be a long period southerly swell that
for the most part remains offshore over the outer waters and
shorter period wind wave chop from light southerly to southeast
winds. Forerunners from a more significant swell group from the
west will arrive on Wed and peak through Thursday. Winds in the
offshore waters also strengthen Wednesday into Thursday,
generating associated rougher seas in the offshore zones, however
conditions are expected to stay below advisory levels. Tdj

Fire weather Dry conditions will persist generally unchanged
through the end of the weekend, with poor humidity recoveries and
periodically breezy easterly winds along ridgetops during the
overnight periods. This may yield elevated fire weather conditions
in a few areas, and mostly in exposed high elevations.

Meanwhile, confidence continues to increase regarding the arrival
of significant wetting rain beginning sometime Tuesday night and
Wednesday, and continuing on and off through the end of the week.

While exact totals are somewhat uncertain, confidence is high that
widespread significant wetting rains are expected over the course
of several days. This is very likely to moisten fuels throughout
the region.

Ca... None.

Northwest california coastal waters... None.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
