A Historic October Warm Spell

It hasn’t happened in 23 years here in Portland…4 days in October at/above 80 degrees.  In fact we average an 80 degree day every other October or so.  Take a look at the “scorching” high temps today:

How unusual is it to see 4 or more 80 degree days in October in Portland?  Here are the years…

2014: 4 (+1 tomorrow???)
1991: 6
1987: 5
1980: 6 (first 6 days of month…consecutive)
1979: 4
1952: 6 (first 6 days of month…consecutive)

    Rob, No news for a while. I for one enjoy your perspective and analysis. Thoughts on this winter?

    Thanks for the time and efforts!

    • Hey, SW.

      Ye, nothing from me, and this is my first time browsing the Blog in over a month. I appreciate your words, but I just don’t have much interest or passion anymore to offer any analysis.

      Take it easy

    Trust me, I get outside plenty. I don’t find many of the nuances enjoyable outside when it comes to cold, windy and dumping rain 9-10 months out of the year. But, I put up with it as long as I can and wait it out until my warm sunshine returns. A little bit of snow always makes the “off season” a little more enjoyable, however. 🙂

    NATIONAL WEATHER SERVICE PORTLAND OR
    354 AM PDT WED OCT 8 2014

    BOTTOM LINE AFTER A LOT OF DISCUSSION…CONFIDENCE IS HIGH THAT WE WILL GET A CONSIDERABLE AMOUNT OF RAIN BY THE MIDDLE OF NEXT WEEK…
    LIKELY MEASURED IN INCHES FOR MOST OF THE FORECAST AREA. CONFIDENCE IS MODERATE THAT AT LEAST ONE OF THESE SYSTEMS WILL STRENGTHEN ENOUGH
    TO BRING STRONG WINDS TO THE COAST. CONFIDENCE IS LOW ON THE TIMING OF EACH INDIVIDUAL SYSTEM AND THE EVOLUTION OF THIS PATTERN AS WE
    PROGRESS FURTHER INTO NEXT WEEK. CONFIDENCE IS ALSO LOW ON WHETHER OR
    NOT WE WILL HAVE ENOUGH RAIN TO CAUSE HYDROLOGIC ISSUES. STAY TUNED AS WE WILL GET A BETTER GRASP OF THE FINER DETAILS AS TIME GOES ON.

  6. PurpleHaze says:

    Considering we seem to get stuck with one steamy airmass after another inrecent years we might as well go the whole nine yards!!

    El Yucko!

    Salem and Eugene both had 86F and Eugene tied a record from 1987. Hard to believe our record lows are in the low 30s at this point and now that’s unattainable. Today’s record low is 29F in fact from 1970!

    Brrrrrrrrr!

    • W7ENK says:

      Kyle, I wouldn’t exactly call this airmass “steamy”. It’s been pretty dry, actually… incredibly so. Now, if we were getting these 80+ daytime temperatures while averaging a tenth to a quarter inch of rain per day, then sure, steamy would be an appropriate adverb.

      It will be a nice and a welcome change once those lows in the 30s start showing up, though. It’s Fall, I’m ready… and waiting.

    • Brandan - Damascus 675ft says:

      Who’s Kyle?
      I’d call this airmass steamy. Went golfing this morning and the dew on the greens didn’t dry up until 1pm(played 18.) Good grip on the club and no ash on the elbows.

    • Mark Nelsen says:

      It may not be steamy, but unusually humid for sure. Dewpoints in the low 60s are unusual in October, especially under sunny skies!

  7. High Desert Mat says:

    I think its safe to say it now that summers over that for the year I had a diurnal change of 128 degrees. A high in July of 101 and a low in February of -27. Pretty impressive for a five month span.

    • Tyler Mode says:

      That’s insane! The highest range I’ve ever had in one year was 96.6 degrees in 2009 (105.2 and 8.6)

      I always think of interior Alaska…highs in the mid 90s sometimes in summer, lows approaching -50 in the winter. Some of the largest differences on earth I would think.

      For this year, it’s 81.5 so far, unless it falls below 18.5 before the first of the year.

  8. marinersfan85 says:

    Only one of those winters had big snow. Winter cancel everybody.

    • W7ENK says:

      Which one?

      I know that both 1979 and 1980 had massive ice storms — exactly 1 year apart — so there’s always that possibility…

    • Mark Nelsen says:

      Should a make a WINTER IS OVER graphic yet?

    • Justin says:

      1979-80 had a big snow event for Portland, south of Foster Road it was all ice.

    • Garron near Washington Square says:

      1980-81 would be a great graphic for this winter Mark. I HOPE I’m kidding! Gonna be a wet Nov/Dec, followed by a Boring Jan-July, if that is the closest relative to this year…

    • High Desert Mat says:

      Way to stir the pot Mark. Dont get them all going til at least February please. I for one believe it will be an average winter around here.

      Erik and Justin, what happened in those winters you speak of?

    • marinersfan85 says:

      1979-80 had 12.4″ in Portland.
      3.5″ in 1987-88

    • W7ENK says:

      Josh, I don’t think those records reflect accumulated ZR. Both 1979 and 1980 were really bad, particularly inside The Dome! I can only go off what my parents have told me, as my consciousness hadn’t really begun at that point.

      If what Justin says is true, it would definitely make sense that if Milwaukie had ~1.5 – 2 inches of glaze ice, the airport would likely have seen all that in 12-15 inches of blowing snow.

      I’m willing to bet the ZR storm in 1980 was a bit more widespread, and again wouldn’t show up in the records.

    • Big snows in Clark County and the gorge in January of 1980.

    • Mark Nelsen says:

      January 1980 storm snowfall in the western/central Gorge was the greatest of all time as far as I’m aware. 36″ or more in one day!

    • High Desert Mat says:

      Thanks for the info guys.

    • High Desert Mat says:

      Is that the year Bonneville Dam set the all time record for most snow in Oregon in a one day period of 48″?

    • Mark Nelsen says:

      It was, although I think it was 39″ at Bonneville. Hood River or Parkdale were around 40″ in one day too.

  9. High Desert Mat says:

    74 at 11:30 already. Headed towards about 85 today. Crystal clear skies and beautiful. Enjoy it while we can. Big changes are imminent.

  10. David B. says:

    Boring, with lots of wailing and gnashing of teeth when Arctic Blast No. 1 proved to be completely dry with no snow at all. (And yes, I was one of the complainers.)

    • David B. says:

      That was meant a a reply to Mark’s comment about last winter below. Somehow it ended up as a top comment. Strange.

    • W7ENK says:

      Happens all the time to me, too. I don’t know why it does that, must be a WordPress glitch or something…

  11. Paul D says:

    I’ve had enough of these 80+ days in October. GO AWAY HOT WEATHER! I want my fall back. My wife and daughter were complaining about how hot it was yesterday too. Enough already!

    What’s with the rumor of a significant pineapple express this weekend? Are we talking normal rain? Or a biblical 1996, 1999, 2006, 1964 type event? Mark, you’re the only guy I trust! What’s your take?

    • Mark Nelsen says:

      None of that here. In fact the GFS is now trying to give us almost no rain Saturday and the ECMWF has no rain Sunday…Weekend forecast is still TBD!

  14. …stocking minimal supplies at the bottom of the cliff this winter…. 🙂

      Hey Larry! good to see you checking in. Gotta keep us ol timers in the game. BTW at the Sisters music fest, a guy you need to hear is Shakey Graves

    Go Hawks!!

  19. Will we get a “Historic Late February Warm Spell” a few months from now too???

  20. John Liu says:

    I’m starting to get anxious. What if we don’t get a solid winter? Maybe last winter spoiled me.

    • Mark Nelsen says:

      Unlikely we’ll see that much cold/snow again, although remember that most of the winter was incredibly boring!

    • W7ENK says:

      Most of every winter here is incredibly boring. It’s both sad and incredible the way a single day (or maybe three if we’re really lucky) can make the difference between an historic and memorable winter or a complete bust.

    • dharmabum says:

      I beg to differ, I find the winters here quite fascinating and different from each of the previous years. Try and get outside and enjoy all the various nuances W.
