A September Scorcher

5pm Friday…

Whew, as expected a hot and windy (and very dry) day!  We hit 90 degrees at PDX, but the record is 101 back in 1944 so no record.  PLOT_Highs_Metro

Check out the relative humidity well down into the teens.  


I see Eugene at 4pm was down to 9%!  Definitely not a good day to flick a cigarette out the window of your car…like any day is but you know what I mean.

As expected the wind made it all the way to the beaches too.  Right around 90 on the north coast and up to 95 at Florence!  I see the wind switch at North Bend from East to WSW dropped the temperature from 91 to 66 in one hour!  That’s some natural air conditioning isn’t it?



Models say the low-level airmass warms up to 5 degrees in the western valleys tomorrow as offshore flow continues.  So we boosted the high temp to 95 degrees.

Sunday the wind will be calm in the western valleys, but residual warm air should still push temps well into the 80s.

Stay cool and enjoy this (almost) last gasp of Summer!  Fall rains can’t be too far away…

    This really has been almost an EPIC summer! I will take this weather all day anyday versus what we have coming! Cold,rain,wind,dark,damp,dreary,cold….Need i say more.

    • W7ENK says:

      So, if your area received 20 inches of snowfall last winter, this article is claiming that you could potentially get up to 400 inches by next spring?!?


    • Garron near Washington Square says:

      In our case, you can take the usual trace of slush that’s gone by morning, and multiply by 50 times, and you get = 50 heart breaking chances the kids will get a snow day…YEA!

    I think it’s really funny, all the people here who whine when it gets hot, but then are the first to try and shut the rest of us up when we gripe about the prolonged dark, grey, cold and wet crap we get ad nauseam, every year. I agree with Mark et al — surviving through 10 months of that garbage weather with the occasional (though all too rare) excitement so we can bask in our 2 short months of beautiful warm sunshine is more than fair. MORE THAN! If you really want a fair shake, then let’s split it 50/50. That way, no one gets to b!+ch. Can’t afford air conditioning? Go hang out in Wal-Mart all afternoon. Five dollars gets you unlimited rides on a MAX train all day, the A/C on those things is usually cranked to Siberia mode this time of year. Or, just grin and bear it like the rest of us do with your crappy cold rain for a disproportionate amount of time.

    I can’t ride my bike to work and back in the warm sunshine that I’ve been waiting 10 months for when it’s dumping 45 degree rain.

    I can’t go out into the woods and enjoy the warm sunshine with my feet dipped in a cool creek, a line in the water and a beer in my hand when it’s dumping 45 degree rain.

    I can’t hike to the top of a mountain and break above the treeline into the warm sunshine at the summit when it’s dumping 45 degree rain.

    I don’t even want to leave my house when it’s dumping 45 degree rain! And I’m willing to bet you heat haters don’t wander the streets and take leisurely walks to the grocery store, or hike, or bike, or fish, or do much of anything outside your four walls when it’s dumping 45 degree rain, either.

    You moved here to get away from the heat? Sorry, but you didn’t move far enough North. Try Alaska, on the coast.

    Leave my warm sunshine alone!! >_<

      Bravo + 1. Peace.

    • Joshua says:

      Talk about exaggeration… There are only 3 months of the year in Portland where the mean temperature is 45 degrees or below. It hardly ever dumps rain either. In the scheme of things, we are neither cold nor wet here. We are cool and damp for a few months, but nowhere close to 10 months. And if it is so bad for 10 months here, why don’t you move to Phoenix or something?

    • Portland has a warmer overall climate than most of the metro areas in the Northeastern U.S. due to our mild winters. And the summers are almost Mediterranean-like, except in cool years. Most of northwestern Europe has much cooler summers and a longer season of sub-55 high temps, than we do here. Portland’s typical winter gloom only goes from November through early March, except in nasty springs like 2011. You have a much shorter window for warm weather in places like the British Isles than you do here.

    • Boydo3 N. Albany says:

      That’s a good description Erik. But as much as I too love the sunny days and get just pissed off when the 35 degree fog lays on us endlessly at times in the winter…. I might counter by saying it’s really tough to get great skiing without the cold and wet.
      It’s really tough to feel the thrill of fishing for winter steelhead without the cold and wet.
      Picking those tasty fall mushrooms is nearly impossible without the cold and wet.
      Walking through an old growth forest has a quiet, unsurpassed beauty when it’s cold and wet.
      Last but not least, sitting by a crackling fire, sipping a hot buttered rum while a rain storm rages outside is a real treat when it’s dumping and 45 degrees.
      And dreaming of those warm, sunny days to come.

    • W7ENK says:

      That’s all well and good, and I don’t deny any of that. My point is, we get to build the snowpack in the mountains, and we get to sit by the crackling fire while the cold wet dark damp gloomy rain rages on outside from (most years) Labor Day through the Fourth of July. If 45 degrees is too much of an “exaggeration”, then let’s go with 55 degrees. I have it in my records that we’ve gotten 55 degree rain in September, October, November, December, January, February, March, April, May and June. That’s 10 months where it can, and some years does happen. That leaves us only July and August most summers to enjoy truly dry, warm sunshine. Two months. Hardly an exaggeration there. This year we lucked out and we’re getting an extended summertime. I’m just saying to enjoy it, don’t b!+ch about it. It will be gone soon enough and the cold wet dark damp gloomy raging dumping rain will be back… for another 10 months.

    Hey Boydo love your pic for your posts, 12 months of snow for me please would do just fine! We need to make up for this hot dry year. Wells are running low and need a replenishment from mountain snowpack. More sediment and sand being pumped from wells now than I can remember and I’ve been a water well tech since I could practically walk.

    • Boydo3 N. Albany says:

      Record number of 90+ days in this part of the world. Hoping my son’s well doesn’t go dry down in Creswell. As warm as I can remember…..and I’m really old 🙂

  6. Paul D says:

    The next three days are looking good – below 80!!!!!!

  7. Boydo3 N. Albany says:

    We were in Sisters for the music fest. Perfect weather there although Friday night got pretty chilly at one of the outdoor venues.

  8. WEATHERDAN says:

    83 at 3:00 PM. Yesterday we hit 97 but this morning we dropped 49 degrees to 48. You might say our temps last night dropped as fast as the chances of Michigan State winning the national championship. Anyway it should still rise to about 87 today. Not bad for September. Then a brief cool down to as low as 78 on Tuesday, then another warm up coming for next weekend. With maybe a couple of more days close to 90. I agree with you Mark. We get at most 25% of the year for nice warm weather. I don’t think that is asking for too much. Anyway for a while at least Summer rolls on. Peace.

  9. Dave in SW PDX (235') says:

    Only 68° here at 11:30AM, 15° cooler than yesterday at this time. And 59% RH, too. Onshore flow doing its thing… feels nice.

    Marine air is now coming in at Astoria!

    • N3EG says:

      Not moving too fast – just reached 98 at Longview.

    • JERAT416 says:

      I feel today was a complete bust for most of the coast. Got to seaside around 10 this morning and it was beautiful and sunny with NO east wind. Cannon Beach was socked in with fog, again NO east wind. Continued south, view points were socked in, the water and sand weren’t even visible, with NO east wind. Finally, some sun in Tillamook. Then, still on and off cloudy with minimal surf visibility, and then at Lincoln City, it was cloudy and chilly with no sun at all. No east wind anywhere down there that I could feel. Funny how the wind was supposed to be stronger today, but in reality it fizzled out probably at the crest of the coast range. Now back home in Beaverton, after a long day of freezing in shorts, I feel great outside in jeans and a sweatshirt. Bring on 1949-50 Winter, just skip fall, I’m ready.

      • Mark Nelsen says:

        Today was a really tough coastal forecast, timing of the wind switch is always problematic when making the forecast. We knew the entire coast would be under southwest wind by 5pm or so and east wind would be gone quickly. Just a few miles north it was 81 at noon in Astoria, then down to 63 by 2pm.

  13. WEATHERDAN says:

    91 at 1:00 PM. 93 on Friday headed for 98 today after a low of 52. I see the forest fire in Corvallis is now under control. It was only four miles from the OSU campus and 200 homes were evacuated for a while. More hot weather coming late next week with no rain in sight. What an awesome Summer. Go Ducks. Peace.

  14. Dave in SW PDX (235') says:

    Already 83° at 11:15AM. Gonna be a hot one today!

  15. Garron near Washington Square says:

    I love these conditions! Fun watching the winds play with the temps here and at the coast. At Newport, if you scroll down to yesterday’s readings, you can clearly see the offshore winds vs. onshore effects as the temps rise and fall by large amounts in just minutes.


  16. pappoose in scappoose says:

    “Folks in San Diego will be flying up here for dry, warm conditions. You’ve got to feel sorry for them.”


    • Joshua says:

      The endless string of warmer than normal temperatures and arid rainless conditions this summer are enough to drive a person to insanity. I hope we get paid back in a big way with an onslaught of rain and cooler than average temperatures this fall followed by bitter cold and snow this winter.

    • High Desert Mat says:

      Try living in central Oregon Joshua. Where its endless days of sunshine and absurdly dry conditions throughout the year every year. But it does get cold and sometimes rain and snow too. But that’s why I like it here, the gloomy days are behind me from living on the west side pretty much my whole life.

    • Helen Smith says:

      I agree with Joshua: I get so sick of hearing the wether people saying, oh please, just give us more summer and hot weather. I wonder if it ever occurs to some people that there are those of us who moved here to get away from the blasting southern california and New Orleans HEAT! I can barely get through summer, just counting the days till fall, then to have the hottest summer I can remember in 20 years and a September that seems to not letting go of the 90º heat is truly nerve wracking. I have air conditioning in my home, but upstairs is not cool enough so have to use extra portable A/C units and a lot of people on low incomes are in agony with this heat. It has to break at some time or are we in for a 12 month summer this year? 🙂

    • Mark Nelsen says:

      I figure that we get this weather 2 to 2.5 months a year, then people that love cool and rainy get the other 9-10 months. Seems fair to me.

      It ALWAYS ends in September, there is no such thing as hot October weather here. Yes it’s possible to hit 90 but I think that was one day in 70 years! I say enjoy the last couple weeks of it because it won’t be back for 9-10 months!

    • Mark, I clearly remember being in first grade in the fall of 1988, and we had a TON of hot October weather (high temps 85-90) in The Dalles that year. Not too impressive west of the Cascades that year, though…but there was always 1952, 1987 and 1991. So I have absolutely no idea where you get the notion that “October heat” is an oxymoron.

      • Mark Nelsen says:

        In the fall of 1987 it hit 92 at PDX on the 1st, and 88 a few days later too. That was it. In 1988, it hit 91 on the first, then never made it to 80 again. In 1952 the first 6 days were in the 80s (no 90) and then that was it. In 1991 there was no hot weather in October, but two days in the mid 80s. So I guess I should have said it’s possible to hit 90 in extreme years in the first week of the month. We haven’t been above 85 even in the last 23 years at PDX in October, so it is indeed very rare to see and “endless summer” continuing into October, and the few times it has, it was over after the first week.

    • Yes…a “Summer in October” pattern is fairly rare – but not “nonexistent.” And in October high temps of 85-88 ought to count as hot, especially if they happen after a period of cool weather in September.

    • dharmabum says:

      living here in pdx area for more than 60 years, you can just about count of a warm dry stretch in early to mid-October most years. I always took the first 2 full weeks of October for vacation every year before retirement!

    • dharmabum says:

      I also remember a late September hot day back 10 or so years ago where in the last few days of the month we were in the upper 90’s in PDX

    • Garron near Washington Square says:

      I wonder if the hotter summers’ can be attributed to all the people moving here to escape the heat? More bodies injecting heat into the atmosphere….Now THAT”S what I call man made global warming! Just being funny of course, we love all our new Oreagun citizens.

  17. Jason Hougak says:

    101 in 1944
    How accurate were thermometers back then?
    The national weather service map shows a tropical storm warning off the coast south of California. I’ve never seen one so close. Maybe they’ll be hit with the remains and help aid in drought relief. One could only hope.
    Be interesting if we got hit by tropical remains to help us too.

    • dharmabum says:

      It wasn’t “that” long ago Jason. Believe it or not there were jet planes and rockets in 1944! Also a lot more common sense and practical knowledge too. I bet they could build an accurate thermometer without too much effort, or as I sometimes hear currently referred to “temperature gauge”!

    • Mark Nelsen says:

      Actually the mercury thermometers were probably a little more accurate than some of the digital ones now. It’s all about the siting/location though. Put a thermometer near a building, whether it’s 1914 or 2014 it’ll read too warm!

    76.7 ° here at 3 in the morning with strong east winds. I love September!

    “Only” 88.9° here in east Portland. It’s pretty typical for it to be a bit cooler here than at PDX during this type of east wind event.

  21. Timmy_Supercell (Klamath Falls, OR) says:

    I got to 84. More or less an average September afternoon on the southern east slopes. Records for highs are well into the mid 90’s these dates, I won’t come close to them.

    Very dry conditions. KLMT @ 4:53pm – Dewpoint 15.1 – 8% humidity.

  22. Tyler Mode says:

    92 here, but I think my gauge is running a little warm.

    This after a low of 47 last night. Tomorrow looks like one of those optimal hot September days, offshore flow dying, dry air in place, and a very warm air mass overhead.
