Excessive Heat Watch issued for region as temps to climb into 90s
SEATTLE -- I know after a very cool May, June and July that there were a lot of people around here eager for some sunshine and warmer temperatures for August.
After this week, we might have to file it under "careful what you wish for."
The next 7 days are going to feature some very hot, then very humid weather that Seattleites are not accustomed to. It's as if we're going to the desert, then going to the tropics.
First up is the heat as our second heat wave of the summer begins building...now. A warm air mass is already in place -- evidenced by the lack of marine pushes and any cooling the past two days despite a weak onshore flow. Highs the past three days have been 83, 87 and 87 with another day in the 80s set for today -- all done without any east wind.
Well, here comes the east wind, courtesy of a building thermal trough. That means you can forget any clouds in the forecast from now through Friday and just focus on temperatures.
The climb starts Wednesday as temperatures will warm into the upper 80s.
The warming east wind energizes for Thursday as the thermal trough sits off the coast and highs will climb into the 90s everywhere -- even on the coast. An "Excessive Heat Watch" is now in effect for Thursday and Friday for essentially all counties that touch I-5 plus much of Mason and Kitsap Counties and the interior of Grays Harbor County.
Thursday's high temperatures should be about a repeat of the highs from Aug. 4 -- Seattle hit 93 that day and that's what we've got for Thursday again, with mid-upper 90s likely south and east. Portland and far southwestern Washington should get into triple digits.
But as the trough moves inland on Friday, we expect the Puget Sound region and I-5 region to actually warm a few degrees to the mid-upper 90s. The Cascades foothills and southwestern Washington could again get well into the upper 90s with maybe a rogue 100. We do expect the coast to cool down back into the 70s to low 80s.
Now those three days are fairly classic heat wave routine - maybe a touch warmer than usual but record highs are in the mid-upper 90s so not unheard of.
But the trick this time is that it's not a push of marine air coming in that would cool us off, but rather an area of low pressure that will move in from the south on Saturday. This will turn the flow from the east to the south. While that will take away the heat effect we get from the east winds sinking down the Cascades, it will instead transform into the one pattern that we get humid -- a southerly flow that will bring up warm, moist air from the south.
Thus for Saturday, expect perhaps some brief low clouds, then clearing, only to have clouds increase again from the south, with a chance of showers and thunderstorms as we get into the afternoon and evening hours -- again from south to north.
The high temperature forecast is very tricky here as it'll depend on any marine clouds that make it in Friday night, the increasing humidity that will start us off warm Saturday morning, and how much sun versus clouds we get in the afternoon. We're going to say low 80s for now, but this can go either way right now -- I wouldn't be surprised to see 75, wouldn't be surprised to see 87. But it will be increasingly muggy and thus whatever the number is, it'll feel a lot warmer and not very comfortable.
Scattered showers and thunderstorms remain possible Saturday night into early Sunday morning, then they go away and we begin to clear up again. As you can imagine, this is only going to increase the wildfire dangers around here.
As for Sunday temperatures, forecast models do indicate we'll get some ocean breezes to get us back into the 70s but we'll have to see as again, this isn't a very typical pattern.
Long range models us back to a morning cloud/afternoon sunshine routine for early next week, although no real big marine push seen out there and the air mass doesn't really, cool, so I suspect we'll remain relatively warm.
By then, we might be wishing for some cooler weather to return.

I want a good lightning storm after this is over!
I wouldn't have said this in June, but I picked the right year to buy a boat. The swimming in Lake Washington has been nice a refreshing this year.Â
I actually like the warm weather and moderate humidty...feels so good on the skin. Only problem is my wife hates hot weather (even though she is from the tropics), and hearing her complain will not be fun. Oh well...it's only a few days of warmth. Having hot weather like this actually makes me appreciate cool raining weather too when it comes. Oh...BTW...I really hope for thunderstorms this weekend. Like Socal, weather here can be so boring.
I feel for all y'all. I live in North Texas and this is what our weather is like from May to October. Please remember to drink plenty of fluids to keep yourselves hydrated and also please remember to wear sunscreen as well. Hopefully y'all have some sort of air conditioning. One thing I would also like to ask is that if you have elderly or sick neighbors, please check on them frequently as their bodies have a hard time with the heat. Prayers coming your way.
@Lori P Air conditioning is the one thing most of us don't have. That is why we whine so much when it get hot. At least our heat waves only last 2 or 3 days before the sea breezes kick in.
Good luck yourself if you are in N Texas. Too hot for me!
I'm looking forward to a few weeks from now, when the weather cools down and is rainy, so all the people who complain about the weather this weekend and wish for cooler temps with rain, have something new to complain about.
How true!
Deal with it y'all.
Â
Bring it on! I want to see some more high temperature records fall! But looking at this http://www.wrcc.dri.edu/cgi-bin/cliRECt.pl?waseat , it might be somewhat tough to do the next 4 days.
@JAP506 rad, someone who actually does not complain when the weather warms up and is sunny,
Be careful what you wish for. All over, weather patterns are very different from what they used to be. I don't think its a positive sign.
91 degrees here at 11:15pm. I love South Texas and I sure don't miss only having 2 weeks of summer. I had better summers up in Alaska than I had in 37 years in Washington. Too hot, too cold, just enjoy it, it will be Octorber before you know it.Â
@Kodiak I actually like it here just fine. Glad to see that everyone is where they like to be though.
Enjoy.
@Kodiak you, Howard Beale, and JAP506 are now the only people I like in western washington.
@northwestsurfer Why thanks! The sad part is I had to move 2600 miles away to escape all the rotten weather. 3 years of an almost non existant garden, rotten horse feet, and all around doom and gloom pushed me and my wife over the edge. Its funny that my bride an Alaskan native got out of the pool the other night: Water 92, air 87 and was cold. I'll take the heat over foot fungus all day long. Ride the wave my friend.Â
BRING
Â
IT
Â
ON!!!
I just drink a lot of Iced water, and use a spray bottle full of water on myself to keep cool, on days like this. No complaints
I have a foot bath that I will with a little ice and cold water. I put my feet in it for a minute or two at a time. You would be surprised how well that works.
Seems fine to me. It's nice to break a sweat working out in the yard. Drink some water, play in the dirt, harvest the veggies...
Â
It's all good. The gray and wet will be here soon enough.
Â
I think I'll spend the weekend up at Sunrise on Mt. Rainier.
San Fran has the best summer weather http://www.weather.com/weather/tenday/San+Francisco+CA+USCA0987:1:US
YES!!!
 @makeadifference I swear this area has the least tolerant folks in the country. Any slight change, to anything and world is falling apart. Even the weather reporters sound like they can't handle a 20 degree spread and they describe it as a Excessive Heat Watch - for what - 2 or 3 days a year? Ya'd think this place was burning to the ground by their description. If it's all that uncomfortable, drive the AC equipped car to the lake and relax. Or go catch a movie. Or better yet, grow some skin and get a tan. Enjoy it while you can because the gray gloomy depressing rainy days of spending 11 months inside isn't far off.
Â
too hot --I want to move to AstoriaÂ
Wish I was partly rich. I'd be living in Long Beach tomorrow.
@John Regan Then move!
Â
As you may be able to tell from my handle, I got more than a few Scandinavians in the family tree. So let me just go ahead and say that:I DON'T LIVE AT 48 DEGREES NORTH FRIKKIN' LATITUDE TO PUT UP WITH 90 DEGREE FRIKKIN' FARENHEIT!
But that's alright... while I have to put up with just a few days of uncomfortable heat a year, the sun-bunnies have to shrivel up and die in 6 months of cloudy and 60. And that *does* serve to keep the more idiotic Californians south of the Columbia River where they belong.
I like between 70s and 80s better,90s too hot !!!!!!
