Tuesday Recap: Near 100 in Metro Area & Smoke Moving In

11pm Tuesday

Today was a scorcher as expected, although temperatures were a notch or two below the forecast high here in Portland

Other parts of the state were incredibly hot

That Medford high and forecast for tomorrow is just amazing.  114???  Wow.

So how will we end up 5-8 degrees warmer tomorrow here in the Willamette Valley?  It’s all about the wind direction.  Today we had weak onshore flow and light westerly flow through the Gorge.  Overnight and tomorrow the hot thermal trough of low pressure shifts west of the Cascades.  That produces light easterly flow through the Gorge and over the Cascades.  Add that to a slightly warmer airmass and it’s going to be a blazing hot day Wednesday…the hottest in 8 years for many of us.  We’re forecasting 105 in Portland, although there is one thing that could drop that temp a few degrees…smoke.

Take a look at the GOES-16 image of smoke surging south from British Columbia wildfires this evening

Soon after 7pm, air quality took a huge tumble in the metro area.  As of 11pm it’s considered UNHEALTHY in Portland.  IF that smoke thickens much more, that will cut down on energy coming from the sun and our temperatures won’t rise as much as expected tomorrow…we could end up at 101 or 102 instead of that 105.  Regardless, it’s going to be a hazy and hot day around here.

    Oh, The smoke is imeding our solar a tad bit…but still managed to cook a mess of Chilly and cornbread up.

    We have been running the generator (because we had to replace the regulator in it and had to empty out the old gas) and been using solar power all day today.

    Pretty much killed all breakers, so if the power goes out, we will have no way of knowing it.

    We have HughesNet that Jupiter system isn’t that bad, it is pretty darn fast.

    Been a lot better than CommyCast or CenturianLink.

    I couldn’t decide whether I should go outside for a run or smoke a cigarette. I don’t smoke, so I guess that’s settled. I ran yesterday morning in Happy Valley Park and I’m guessing it was in the low 50’s there. My hands actually got a little cold early on.

    Interesting point D Burnett made yesterday. If the smoke lingers tonight and holds the temp up, then clears out tomorrow (Thursday), we could be in for that all time record breaker!

    • If you’re outside in my part of the world, you’re inhaling smoke whether you want to or not! It’s ultra super hazy here today. Doubt if the visibility is much more than 2 miles up this way. My eyes started smarting just on the (short, under 1/2 mile) bike ride to downtown and back.

  5. Roland Derksen says:

    I think the smoke is at least doing one thing good: Keeping the afternoon temperature down a bit lower than expected. I had the same 85F maximum yesterday as the day before. Today, it looks a little clearer. Maybe the wind direction has changed. If so, It’s going to be warmer.

  6. JohnD says:

    For those of us pulling for an all time record at PDX, the haze is looking problematic–as Mark has alluded. Dang!

  7. Jason Hougak says:

    It will be feeling like hell, not to mention starting to look like it. Heat, smoke, smog… I’ll take winter.

      I really like the look of snow!

    • Paul D says:

      A normal mid-October day would be good too.

    • Gene says:

      I think most locals would NOT prefer a normal mid-October day, but a normal July/August day instead. After all, it is summer! You’ll get your dark, damp, chilly, cloudy weather in due time. For the rest of us (which I’m guessing is a huge majority of Oregonians), we will enjoy a warm, sunny Oregon summer — for that small window of time we get it each year

    • W7ENK says:

      Gene, you’ll never get that point across to Paul D. He started whining about hot weather back in mid May when our highs started reaching into the upper 70s. He doesn’t usually stop whining until around Thanksgiving, once the scabs from distant memories of Summertime butthurt finally heal over.

    • Paul D says:

      I made a resolution to not whine if temps were normal. These ain’t normal, so !

  8. Paul D says:

    Come on smoke!! Keep those temps down!!

  9. Lee Wilson says:

    I don’t like smoke, it causes my asthma to act up.
    I do enjoy the sun.monday i had to use the dryer..but now we just hang the clothes on the line.

    Kinda curiou to see how our energy bill will fair after all 8s said and done.

  10. Is this scenario possible?: Smoke builds up tomorrow and lingers until the hours just before dawn on Thursday. Overnight temps are kept well in the 70s due to the smoke, but the clearing before dawn allows temps to soar to 107 or above on Thursday.
