Still, you say that you ...I like the site as well. Still, you say that you would rather have this milder summer than you saw in the East when you were back there. Well, I agree with that, BUT the problem is having this huge cloud cover and/or rain for so long out of the year. It makes the climate here pretty much unbearable for a transplant like me. Now, the normal PNW response I get is to get the hell out of here if I don't like it. Well, I guess I have taken that advice. We have a time-share in So.Cal. where we used to live, so while the locals here in the Podunkland, Oregon area are saying that they are close to 21 days without rain, I am now over 60 since I left and returned. The PNW is normally known for very nice summers, but the last two years have been ridiculous. I have had to resort to leaving in order to get our summers. C'est la vie, I suppose.Unknownhttps://www.blogger.com/profile/14779538572390937210noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-8692563342700364182011-07-31T18:22:46.646-07:002011-07-31T18:22:46.646-07:00Given that Dr. Fog is using data "at Sea-Tac ...Given that Dr. Fog is using data "at Sea-Tac Airport", I think it's safe to assume that they're taken from METAR observations, and given that, I'd assume he's tallying up hourly reports that have at least one OVC, BKN, VV, CU, or CB component.<br /><br />He might be counting SCT and even FEW as well, but it wouldn't matter much, given that the purpose of the chart is to compare the current year to averages of previous years.RobotSlavehttps://www.blogger.com/profile/09848632559112974545noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-91601841101924452782011-07-31T11:10:44.671-07:002011-07-31T11:10:44.671-07:00What amount of sky coverage constitutes "clou...What amount of sky coverage constitutes "cloudy" for Dr. Fog's data?

I especially wondered that relative to today's "cloudiness" plot -- how big are the error bars on the averages? Are we outside of normal this year, or just relatively high? Error envelopes are my favorite way to show uncertainties, since they allow you to easily intuit whether two ranges are really different. E.g., http://bit.ly/oIVmUI .
