Hunker Down in a Cool Spot…100+ Likely Today!

9am Thursday…

Today should be our hottest day in 3 years in Portland.  The airmass overhead has warmed a few degrees, we actually have an easterly wind blowing through the Gorge, and it’ll be sunny the entire day.  By 5pm we can expect to see widespread 99-103 degree temperatures through the Willamette Valley and Portland metro area.  The last time we hit 100 was in August 2012.  Regardless of the final temp, it’ll be the warmest of summer so far.  Notice no one in the metro area has moved above 99 so far this season:

Tomorrow will be a scorcher as well, but probably not 100 degrees.  Then we slowly cool closer to 90 Saturday and Sunday.

Believe it or not, we won’t have a record high in Portland today since this is one of three days we’ve hit 107 degrees; our all-time high.  It happened on July 30, 1965 and then again TWICE during the great 1981 heat wave.  We were 107, then 105, then 107 again over a three day period.  That was August 8-10th, 1981.

    Blue Moon, Belt of Venus

    The full “Blue Moon” rising tonight over Mt. Hood along with the purple hues of the Belt of Venus

  2. Tyler Mode in Battle Ground says:

    100.5 at my house today. Many areas 101-105 for a high.

    This after lows in the mid 50s this morning. Not often we see such a wide swing between morning lows and afternoon high temps. This is more like late August/September diurnal ranges.

    Just wanted you to know us Missourians sent our hot weather to you guys for awhile. With that humidity level, you are only hot in the sun, you don’t know heat till you see 100 with 60 percent humidity like we just had, some low humidity for a couple days. What a relief—thanks for taking on our heat for a few days. I know you will be sending it back this direction, Drink plenty of water stay out of the sun, a nice damp towel around your neck helps—-happy sweating

      Well, thanks for that! I know you’re the Show Me state, but please don’t show us any more of this! The good news is we can drive an hour and a half west and chill out to 65 deg at the ocean, so we shouldn’t complain like we do.

    Topped today at 105.6°F at 3:30PM on my fan-aspirated Vantage Pro in the backyard – the highest recorded temperature since I installed it in 2006. It’s 2 degrees down now two hours later.

    • Dave in SW PDX (235') says:

      103.2°F on my VP2 (w/o fan aspiration) today; ditto for highest temp since installation (2010). All the way down to 100° now. 😉

  5. Wendy-Silverlake, Wa says:

    High of 101.7. It’s a bit warm out there. Hoping for some sort of cool down for the weekend as I’m having a BBQ and that’s too warm to sit around where there is absolutely no shade whatsoever!

  6. runrain says:

    Looks almost like an isolated thunderstorm, but I think a pretty good-sized fire has erupted east of Roseburg. You can see it very clearly on the visible satellite.

    • Dave in SW PDX (235') says:

      “The fire, burning about 11 miles east of Canyonville near the community of Milo, is exhibiting extreme behavior and growing rapidly…”

    • ALTHOUGH OUTSIDE OF THE LOCAL FORECAST AREA…A FIRE STARTED AND
      QUICKLY SPREAD IN DOUGLAS COUNTY THIS AFTERNOON AND ITS SMOKE HAS
      SPREAD OVER EASTERN LANE COUNTY AND SOUTHEASTERN LINN COUNTIES. HAVE
      ADDED SOME CLOUD COVER TO THOSE AREAS TONIGHT AND TOMORROW MORNING TO
      ACCOUNT FOR THE SMOKE. THAT FIRE HAS ALSO PRODUCED SOME PYROCUMULUS
      WITH A FEW CLOUD-TO-GROUND LIGHTNING STRIKES AND EVEN MORE IN-CLOUD
      LIGHTNING ACTIVITY. WITH THE FIRE BEING THE SOLE SOURCE OF THAT
      THUNDERSTORM…DO NOT EXPECT IT TO MOVE INTO LANE COUNTY AND THERE
      IS NO THUNDER THREAT TONIGHT ANYWHERE LOCALLY. BOWEN

    • Aleta-West Gresham says:

      My sister said there’s a report of the plume reaching 41,000 feet! I can’t find that but if I could figure out how to post the picture she took from Grants Pass, it makes it pretty believable!

    • Aleta-West Gresham says:

      Fire crews have been pulled off. My sister just sent me this Facebook link. You don’t have to be on Facebook to open it. Some unreal pictures and quite a time lapse.

      I’m not finding any timelapse on their page…

  7. WEATHERDAN says:

    102 at 4:00 PM. Should add 1-3 degrees yet. Just as hot on Friday. Then a slow cool down. But it still looks like it will remain above 90 through Tuesday. Still no rain in sight. Peace.

  8. Eugene Dave says:

    It is Sofa King hot out right now. Blech!

    • Paul D says:

      I’m expecting something to spontaneously combust outside. It’s waaaayyyy too hot.

  9. runrain says:

    It’s OFFICIAL: 100 degrees a PDX at 3pm. Yeah! (Now, please go away, thank you very much…)

    • runrain says:

      What??? Only 99 in Salem???? That can’t be. I thought it was always warmer there.

    • WEATHERDAN says:

      Greetings and salutations. Funny that you should mention that Salem being warmer than Portland. It usually is in the Summer by 2-4 degrees. Of course that is not always the case and sometimes PDX is warmer. The reason is of course the Columbia river. A little sliver of cooler denser and heavier ocean air slides up the river to PDX and keeps the airport slightly cooler. Quite often HLS is warmer than PDX. As for today SLE was 105 and PDX was 103. But as I always say this is not a game just a meteorological fact and has absolutely nothing to do with which location is better. I love to visit Portland to have a beer at one of the great brewpubs or take in a Winterhawks. game. We are after all just 47 miles apart but have a somewhat different climate. Peace.

    Very interesting post by Clif Mass about the building heat bulge over the last two days from around Brookings and points south.

  11. WEATHERDAN says:

    93 at 1:00 PM. So probably 101-103 today and likely Friday. WSI said this morning they expect the heat to return to the Pacific Northwest in the second half of August after a cool down the middle of next week. So between the 5th and the 15rh we are close to normal. Normal right now is 84. So most days in those 10 days I expect to be 80-88 degree range in SLE and 77-85 in PDX. Then warmer but not a 3rd monster heat wave after that. Still we should have a few more days in the low to mid 90,s by the end of August after this current heat wave ends next week. Of more immediate concern is the wildfires. Salem got only .01 of rain last weekend. So the mid and Southern valley remains incredibly dry. If we have any convective activity we could be in real trouble. Stay cool my friends. Peace.

  12. The closest we came here to 100F in my town was back in that late July 2009 heatwave. I saw it get up to 98F. I doubt I’ll see it that hot again this summer.

  13. Paul D says:

    Brookings is looking really good the next few days

  14. W7ENK says:

    PDX reporting 91 at the Noon hour.

    Noontime temperature +10 for 5pm high, as a general rule.

    That gives PDX 101 for the day’s high. Add Milwaukie’s usual +4 over PDX, I expect to see 103-105 when I get home this evening. So glad I didn’t ride my bike in today!

  15. I’m actually kind of hoping PDX doesn’t hit 100, so we can brag about a scorching-hot summer that paradoxically has no triple-digit heat 😉

  16. paulbeugene says:

    Looks like high of 103-105F in Eugene today.
    Regardless of whether you live in PDX or EUG, 80F at 10am benchmark usually puts you above 100F for the high, assuming no high clouds coming in.
    In the great heat wave of Aug 1981 it was 82F at 10am on the day it got to 108F in Eugene.

    2009 should have been the all time high temp record for most everybody in the Willamette Valley. High clouds were the only thing holding us back. We had temp of 85F at 10am on one of those hot days…that would have gotten us close to 110F.

    • Garron near Washington square says:

      PaulEugene, thanks for that tid bit! Always helps to put into perspective just where we’re headed the next couple of days.

  17. runrain says:

    79 deg at PDX at 10am, 6+ from yesterday. That would equate to a high of 103 if that rate continues.

  18. Paul D says:

    Something’s missing…..

  19. Paul D says:

    Got all my outdoor stuff done already. Staying inside the rest of the day!

  20. Lee Wilson says:

    As much as it pains me, My Dog is staying home in an air conditioned place.

  21. runrain says:

    Don’t forget to fill out the 7 day. Want to see one of those 100’s there!
