Seattle Weather/Climate Thread (Bellevue: floor, air pollution, fireplaces)

I would have to agree that so far the late fall has been drier than normal,
though I never did see the sun today. Currently 32 and fog, so another night and probably morning to be careful of slick roads. Sure was a commute mess this afternoon with the Seahawks game starting so early.

Indeed an interesting weather pattern but definitely not that unusual that we have several days at a stretch of "quiet" weather for this time of year. Exactly how much sunshine you can get out of this pattern is contingent on how much moisture is around, and with all the rain we've had of late and of course, the proximity to the ocean and Puget Sound, despite all this high pressure, and with inversions so frequent with this type of set up and not to mention low sun angle which makes it even more of a chore to burn off the low clouds and fog; the sun may still not shine as much as you wish, but still, this beats days of rain and inclement weather that's so prevalent this time of year.

So how long will this keep up? would you believe possibly for the next two weeks! However there will be a few interruptions and that could come in the form of lowland snows and even a little ice. The middle of next week, a piece of some real arctic air may make a visit and send temperatures some 10 to 20 degrees below average, this may continue through next weekend Dec 10-11 and may be accompanied by a couple of systems coming directly from the Gulf of Alaska, with this interacting with the arctic air mass, some frozen precipitation will be a good bet, even along the sound and possibly at the ocean too like places such as Long Beach, Westport and LaPush. as of this time though, I don't see anything significant as far as intense storms or long duration events.. however, with this type of pattern, places along the northeastern part of the Olympic Peninsula such as Sequim and Port Townsend may be in for locally heavy snow's, possibly several inches, late next week and next weekend around the aforementioned dates.

Model data for weather more than a few days out can still change on a dime, but as of now, I give this about a 60% chance of my forecast verifying. I'll keep an eye on this for all who are interested.

Ahem..... Could you define the word 'Sunny'. Is that what we have when there's that round shinny ball in the sky? Frankly we haven't seen any of those since September. In fact we haven't seen any sky lately, just fog, cloudy darkness and rain.

I wouldn't say that, I have had to close the office window blinds several times this week for close to an hour.

When I read comments in this forum, I start to get the impression that Seattle must be considerably cloudier than Bellingham. We've had plenty of sunshine up here all through October and November. Sure, there have been plenty of cloudy days too, and some with rain (though not a whole lot), but overall it's been a pretty healthy mix of sunny and cloudy days.

Just spent the last couple of hours outside walking. 37 degrees, dark, cloudy, but no rain. It was very pleasant.

Really? Last Friday was absolutely gorgeous in the Seattle area. Since September, really?

From the National Weather Service re: Seattle

November's 2011 weather for Seattle brought below normal temperatures, sunshine, clouds, and rain after a cool, mostly cloudy, and rainy October. There were fifteen days in November with cloudy sky conditions, fourteen days with partly cloudy sky conditions, and one day with sunny sky conditions.

For public forecasts, the National Weather Service uses the following terms to indicate how much of the sky should be covered by clouds::

Cloudy: 90-100%
Mostly cloudy: 70-80%
Partly cloudy or Partly sunny: 30-60%
Mostly clear or Mostly sunny:10-30%
Clear or sunny: 0-10%
Meteorologists like to say that the difference between "partly cloudy" and "partly sunny" is the forecaster's mood.

OK, when I say some people exaggerate quite a bit, this is what I mean. This isn't even in the same solar system as the truth. I don't need to live there to know this.

OK, I suspect in this case the poster was chuckling himself when he wrote that. Instigation is a form of entertainment for some people.
