Weather 70 degrees in October? No problem this year... 70 degrees in October? No problem this year...
A somewhat sunny and 72 degree day sounds fairly routine for Seattle... for early September, maybe even late August.

But October 19? Indeed, strange enough but then when you find out it's only tied for the third-warmest day this month, it's really something.
Weather Potpourri blog: Cool weather maps, videos, and how not to get a 'Tomato Warning' Potpourri blog: Cool weather maps, videos, and how not to get a 'Tomato Warning'
To kick off the...middle of October week? -- I've got a bit of grab bag weather geek stuff for the blog that's been sitting in my inbox waiting for the light of day, so here goes...

First up, this neat interactive site that lets you compare weather across the nation. For those of you who liked this worldwide rainfall comparison tool I posted last month, this site is for you, courtesy Kristian Nielsen:
Weather Is the recent sunny and warm stretch an ''Indian Summer''? Is the recent sunny and warm stretch an ''Indian Summer''?
October has been on quite the sunny and warm kick. Four of the first six days in the 70s, with a 75 and record-tying 78 on the board already when average highs are in the mid 60s. None of the days the first week have been considered officially "cloudy" and there's been nary a drop in the rain bucket.

For many, these nice stretches in the early stages of autumn are colloquially known as an "Indian Summer." But is there any sort of official definition to make it qualify?

Growing up, I thought the term was pretty informal to mean any kind of nice sunny and relatively warm stretch in October. But a few years ago during a rather sunny and warm stretch in mid-October, I received an e-mail asking since it went below freezing at their home that night, did it make that sunny streak make an official Indian Summer?
Weather Is all hope lost for snow this El Nino winter? Maybe not... Is all hope lost for snow this El Nino winter? Maybe not...
New Year's Eve, 1968 was likely a bit of a chaotic celebration for winter weary Seattleites. Just a week and a half before, a dollop of 5" of snow fell in the city, followed a few days later by two more snow showers that dropped another 3" of snow. Christmas was rather mundane but the days after were anything but as a massive arctic blast rolled into the region.

On the 27th, the high was 37 and the low was 20. On the 28th, it only got up to 22, and dropped to 13.

The next two days wouldn't reach 20 and drop to single digits -- the thermometer tumbling to 8 degrees on the 29th and 6 degrees on the 30th as a winter storm arrived.
Weather Gorgeous time lapse video shows fog rolling into Seattle Gorgeous time lapse video shows fog rolling into Seattle (Video)
As we turn the page into October, it’s not only the official start of the rainy season in Seattle, but the longer nights make it easier for fog to form.

Wednesday morning brought such a foggy morning into Downtown Seattle. Sigma Sreedharan had her camera rolling to capture the fog rolling in just after dawn.

Gorgeous video, Sigma!
Weather Forecasters even more confident in a milder winter in the Pacific Northwest Forecasters even more confident in a milder winter in the Pacific Northwest (Video)
If you've been following my blog here over the past few months, you've seen the forecasts that show a greater than average odds of a warmer-than-normal winter.

The forecasts were based on an expected El Nino event to develop this winter, along with warmer-than-normal water temperatures in the northern Pacific Ocean.

This is one of those times that if you have a large, HD monitor around, go find it and then reload this blog. It'll be worth it.

Mike Olbinski, a fantastic photographer who lives in Arizona, has spent the summer chasing the monsoon storms that wrought towering thunderclouds, vivid lightning, incredible downpours and intense dust storms.
Weather So how best to celebrate autumn? In (corny) song! So how best to celebrate autumn? In (corny) song!
Now, I've learned over the years there is a fairly even split here between those who love the days on end of 80 degrees, and those who much prefer 60s and cloudy. Now that the sun fans have had their tune, it's time for those who are eager to do so to celebrate autumn.

With that, I present this melody to hum today, sung to the tune of Olaf's "In Summer" song from the movie Frozen. (If you have don't have kids, and/or don't know the melody -- which if you do have kids it's likely impossible not to have heard this song, here is the original, and you're welcome for getting this stuck in your head for the next week :)
Weather Seattle finishes up 2nd hottest summer on record at Sea-Tac Seattle finishes up 2nd hottest summer on record at Sea-Tac
The rains this morning were an emphatic end to what will go down as the second-hottest summer on record at Sea-Tac Airport, which has data going back to 1945.

The average high temperature from June 21 through September 21 this year was 79.3 degrees, falling just behind 1967's 79.5 degree average (and just ahead of 3rd place. Guess what summer that was? Last year! 2013 averaged 78.6 degrees)

Our toasty numbers this year make sense when you consider 40 of the 92 days of our summer were warmer than 80 degrees -- meaning nearly half our summer was spent over 80 degrees! And 21 of those days were 85 degrees or warmer with five days at 90 or hotter.
Weather Freak weather event has some Eastsiders sweating in middle of the night Freak weather event has some Eastsiders sweating in middle of the night
We've had plenty of afternoons basking in the upper 70s for warmth lately, but usually by the middle of the night we've cooled off into the 50s and 60s.

For most of us, that was the case Saturday night too, but not over by North Bend, where a freak wind event brought somewhat sweltering temperatures to the local area as the clock struck midnight.

One of those who noticed it was Anthony Gilbert.
