5 years ago today, Seattle baked like it never had before

Those of you who were around here 5 years ago today were likely trying to find some place -- any place -- for relief from the heat.

July 29, 2009 remains the hottest day ever recorded in modern Seattle history, be it Sea-Tac Airport or the Downtown Federal Building, with a reading of 103 degrees. Some spots, like Boeing Field and the NOAA station at Sand Point, were even hotter, reaching 105 degrees. Everett hit 100, Bellingham hit 96, and Vancouver, WA took the heat prize with a 108 degree reading!

For much of late winter and spring, the message has been the same by NOAA's Climate Prediction Center: Expect a warmer than normal summer.

So far, July is delivering, with several days of 80s and 90s around the Pacific Northwest, and even a few triple digit days east of the Cascades. Seattle is just one spot in the region, but it's a whopping 3.0 degrees above normal so far and through Sunday, is tied for the third-hottest July on record at Sea-Tac Airport (Average temperpature (high+low/2) so far: 68.6° -- record is 69.5° in 2009; 2nd is 68.8°.)

And the forecast for this week brings a return of more warm-to-hot weather to finish off the month and potentially cement the month as 2nd warmest on record.

So what about August? Those same long-range forecasts suggest more of the same. And September. And October. And November. And...see a theme developing?

By the numbers: Wednesday's record rainfall

After the first three weeks of July began generally sunny and warm-to-hot, things changed in a hurry on July 23rd as a potent storm rolled through Western Washington, bringing a record amount of rainfall to the Puget Sound region.

Here are some of the statistics from the storm:

The wildfires raging across Washington, Oregon and Idaho are not only bringing a dense, smoky haze to much of the area just to the east of the Cascades, but its effects are being felt over 1,000 miles away across the Upper Midwest.

Jonathan Yuhas, a meteorologist with KSTP-TV in Minneapolis, noted that skies over Minnesota have taken a "frosty haze" to them ever since the wildfires have erupted here in the Northwest.

Many of us in Western Washington are breathing a sigh of relief that our days-long stretch of 80-90 degree weather is coming to an end.

But one region's relief is another region's pain. The process that is cooling down Western Washington is wreaking havoc in Central Washington and the firefighting efforts over there.

With a late surge of warm air Thursday, Seattle managed to reach 80 degrees again -- the 12th day in a row with highs at 80 or warmer.

It's the second-longest such streak at Sea-Tac Airport, tying a streak in August of 1967 and coming up three days short of the all time record of 15 set in 1977.

Forget Kevin Bacon, Washington had 50 degrees of separation Wednesday

It was the hottest of places; it was the coldest of places.

Our state had quite the dichotomy Wednesday afternoon, courtesy of an intense heat ridge in Eastern Washington counterbalanced by a chilly fog bank along the coast.

At 7 p.m. Wednesday, the temperature in Pasco was 107 degrees. Contrast that with Forks on the coast which was... 57 degrees. (Some of the buoys offshore were even a little chiller like Destruction Island at 53 degrees). That's about 265 miles apart for the 50 degree swing.

They weren't a throwback to the tall-sailed pirate ships of yore or a maritime version of a Star Trek Borg, but those who were on the western shores of Puget Sound this past weekend might have had to rub their eyes a bit while gazing out toward Whidbey Island.

Weather conditions were just right to create mirages on the water that turned simple container cargo ships into what looked like...perhaps a 1980s video game rendition of space invaders?

It's been the talk of the town this week, the amazing sunset we had Sunday night across the Puget Sound region.

A lot of people have been asking what caused such brilliant colors: Wildfire smoke from Eastern Washington? Lucky cloud formations?

Yes, and yes, according to University of Washington Atmospheric Sciences professor Cliff Mass. And, add in some evaporating rain for good measure.

July 10th among Seattle's ''Final Four'' of original heat records

July 10th has somewhat of a badge of honor in Seattle weather records -- it's home to one of the last four original record highs for Seattle.

Sea-Tac Airport's first year as the official weather records were in 1945, and of course, every temperature recorded that year is a record high and a record low. Those records fall and adjust higher/lower as the years pass and our weather goes through its expected peaks and valleys.

Now after 69 years, you'd expect those records would have been replaced, and almost all have but there are still four that have withstood the test of time and today is one of them.

Sure, Seattle has quite the rainy reputation, but did you know when records first began being kept in Seattle, there was nary a drop to be found?

In fact, the very first observation in Seattle noted in official record books was: a sunny day!

In February!

(I guess the pessimist would say it had nowhere to go but down.)

I stumbled upon this little fact while researching my blog for Monday about the intense heat wave of 1870. In looking for where exactly in Seattle those observations were taken, I found this incredibly thorough 52-page report on the history of weather observations in Seattle, written and prepared by Glen Conner of Scottsville, Kentucky for the Midwestern Regional Climate Center. Conner's excellent research is the source of this blog's information.
