The climate here is quite moderate, generally.  Winters can be like
this in the higher elevations (I'm at about 900' above sea level), but
this is rarer at the lower elevations in western Oregon:

That above picture last happened near my property in winter of 2003.
But I've not seen the like since then.

We used to get a silver thaw in the lower elevations near ****tland
almost every other year or every year.  I haven't seen one since 1981,
though.  And Mt. Hood has lost close to 50% of its glacier mass
balance (gleaned from personal discussions with two climate
researchers -- one who studies mass balance of the Wa****ngton state
glaciers and the other who personally treks through Mt. Hood every
year gathering surface ice/snow data) in the last 30-50 years.  (If I
recall, there are 11 significant glaciers on Mt. Hood.)  I have lived
here since 1955 and my own experience concurs with this trend.  So the
winters in the lower elevations of the Willamette valley, in my
opinion, have become less severe in terms of ice/snow.  However, I
think, precipitation seems to have remained similar overall.  Just the
distribution seems to be perhaps a little more rain in the winters and
less in the summers.

In short, you'd find it a paradise for photography pretty much all
year 'round.

Yes, it's been weird here, this year.  There seems to have been a
significant change in the wind patterns over the north polar area -- a
****ft in the cyclonal center of mass.  Winds and water currents drove
sea ice along the edge of the Russian Arctic (Novaya Zemlya) and a
sort of polynya emerged a bit early off the Canadian arctic coast
between the archipelago, the Alaska border and Baffin Bay.  This year
seems to be unusual to me in these respects and perhaps may have
played a part in the somewhat unusual (record breaking, here) weather
patterns we've had in the month of May.

By the way, that polynya I mentioned and other smaller polynyas
suggest furthering of the thin and fairly weak annual ice of late.
This is consistent with the fact that the relative fraction of
multi-year ice in the central Arctic has plummeted, roughly since the
mid-1990s.  However, it also seems that this year's first year ice
(brine pocketed) is in an unusual location that may help it survive
better than usually expected -- much of it is farther north than usual
so it might be less vulnerable to melt allowing time for the brine to
expel and the ice to firm up somewhat.  Still, while having first year
ice further north means that ice may have a better chance to continue
a while longer that shouldn't be read as good news -- it means that
first year ice is forming closer to the pole which is generally not
good big picture news and the overall direction of decline there
continues.

As more of the polar ocean becomes exposed to solar insolation, which
has quite a different albedo, I expect continued significant and
interesting changes in the energy transfer mechanisms for some years.
