Just a more benign pattern for the Pacific Northwest.
It can actually be quite a bit wetter and stormier
at times for Central and Southern California.

When the westerlies sag south in the late fall and
early winter, frontal systems start to tap into that
extra warmth and moisture due to the warmer than
normal surface temperatures of the equatorial Pacific.

That tends to build a mean ridge over the Pacific
Northwest and the jet stream splits alot--with one
branch heading toward California, and one branch
heading north into Northern B.C.

For Seattle, we say that we can get a bookend winter--
so we might have got the bulk of our storms (and indeed
lowland snowfall) this past November...and have to wait
til late February or March to get more of that again.

That said, the winter of 68-69 was also a weak El-Nino
and that was the snowiest winter on record for Seattle.
So there are always outliers.

I wouldn't be surprised to see a couple weeks of
quiet weather in Seattle, and then see things move
toward a 68-69 type of winter. But I cant back up
that forecast with anything. The long range models
are not very good past about one week, so nobody
can say what will happen with any skill. Well, that
is not true--the climate center claims very modest
skill at their 30 day and 90 day outlooks. Those I
think call for temps to be near normal and the weather
to be a notch drier than normal for Washington.

I couldn't tell you what the long lead outlooks say
for California, probably dry and warm and now watch
the split flow storms will start heading for San Diego, heh.
