2014 going to end up as much hotter summer in Seattle than 2009

2014 going to end up as much hotter summer in Seattle than 2009

At least as far as recent memory goes, 2009 set quite the standard for a hot summer in Seattle. That year was home to a brutal two-week stretch of heat that peaked at 103 degrees in Seattle on July 29 and had several days over 90.

This summer hasn't been anywhere near as hot, at least as far as peak heating goes. We have four total days at 90 or warmer and a 96 degree reading earlier this month, but no real "trophy heat waves", as I call them. As in: No long stretches over 90. In fact, all our 90 degree days this year have been orphans -- just one in a row.

The science behind the smell of rain

Ever notice there's a distinct smell right after it starts raining?

It's most noticeable when it's been dry for a long while and the shower is fairly heavy. My wife, who grew up in Arizona, referred to this as the "wet rock" smell and there is some truth to it as it's rock that's among the main culprits for giving off the smell.

Who here knew there were thunderstorms last night?

Me neither.

But as a weak trough slid over the region overnight, it managed to trigger a thunderstorm in the dead of night.

As in one. A very lonely thunderstorm.

Seattle on pace for hottest July-August in Sea-Tac history

Seattle has already notched the fourth-warmest July on record by average high temperature (second warmest by average temperature), but apparently this summer has its sights set on loftier goals.

As of Monday night's data, August was also on pace to be the second-warmest August at Sea-Tac Airport, currently sitting at an average high of 81.7 degrees. The record is a lofty 83.7 degrees so we'd need to really turn up the burners to reach that record.

Photo galleries around here are full of dramatic cloud shots created by some of the tallest mountains, be it Mt. Rainier, Mt. Hood or even just the Cascades or Olympics.

But mountains don't have to be measured in thousands of feet to create their own weather patterns.

It's been a very dry summer in Seattle, unless you count the 2 1/2 days it wasn't. Both July and August will go down as having above normal rainfall despite only having measurable rain on six days out of 44 days-- and thee of those rainy days were 0.02" or less.

Here's how Tuesday night/Wednesday morning's rain storm matched up:

Seattle set an all-time weather record Monday night, when 0.02" of rain fell in a shower just before 11:30 p.m. What's so special about 0.02" of rain? It came on a day when the high was 96 degrees.

As temperatures soared into the 90s Monday -- Seattle hit 96 degrees, breaking the record high and making for the hottest day since Aug. 15, 2010 -- many longtime Seattleites were ready to wave the white flag. It's been an unusually hot summer and even though we don't have many "trophy" heat days of us broiling well into the 90s for a few days here and there, it's been a slow cook with several days in the 80s.

We've got about another month on the calendar where Seattle can get this warm but let's "take the temperature" of the summer so far.

Odds of an El Niño this winter drop by 15%

Odds of an El Niño this winter drop by 15%

Maybe El Niño isn't such the slam dunk it seemed a few months ago?

Forecasters with NOAA's Climate Prediction Center – the people in charge of watching for El Niño and La Nina, among many other things – have dropped their chances of El Niño developing this fall and winter to 65 percent from 80 percent.

Granted, that's like saying a football team that was a 14 point favorite to win is now just an 11 point favorite – still a pretty good chance it'll happen. Just not as much as before.

But if nothing else, the trend is interesting.

With the tropical paradise of Hawaii bracing for Hurricane Iselle later Thursday, I've had quite a number of people email and ask why we're not calling the storm "Typhoon Iselle." After all, there's a similar storm just a bit farther west across the Pacific called "Typhoon Halong."

The reason is simple: Geography.

In keeping up with the number of weather records and interesting statistics surrounding our current warm spell, I stumbled upon something on the other end of the spectrum: How difficult it's become to set record lows in the summer.

In looking up the record high Monday when he hit 91° in Seattle (it was 95, set in 1993), the record low stuck out: 44° in 1950.

Seattle is in the midst of another week-plus streak of 80 degree temperatures -- the second time this summer with much of August still tied behind our back.

While there are some sun fans who love the 80s and are basking in this somewhat rare extended warm pattern, there are a vast population of long-time locals -- especially those without air conditioning -- who are longing for the days when we could see a marine cloud in the morning and a '7' on the high temperature (no, not counting when it's "87").

Talk about being in the right place at the right time...

Tom Korocz was at Sea-Tac Airport Saturday morning when he noticed a tall, cumulonimbus cloud towering in the sky as the sun rose around 6:15 a.m.
