Warmest So Far…

Hmmm…I should have stayed with that 85 degree forecast that we had here at KPTV for today all through the weekend.  Amazing what happens when the switch from dry/warm east wind and cooler/moist is delayed a few hours.  Looks like most of the Willamette Valley didn’t hit 80 degrees today.   Here in the Portland metro area where east wind continued until 1-2 pm, temperatures shot into the mid 80s.  Models were slow on the transition (but only by 3-5 hours).  We did not hit a record though since last year on this date we hit 93 degrees with a hot east wind!
A major marine push is in progress this evening, evidenced by wind and pressure gradients.  The gradient from North Bend to Portland is 8.9 millibars at 4pm, one of the higher "SW Push" gradients I’ve seen in the warm season.  Southwest wind gusting 20-30 mph has entered the west side of the valley at 4pm and should quickly swamp the whole region west of the Cascades by 8pm.  It’ll be a very quick cooldown tonight.  I bet it”ll be close to 50 degrees most areas west of the Cascades by 10pm.  Windsurfers can plan on a "dawn patrol" in the morning as 30-35 mph winds blow through the Gorge later tonight and all day tomorrow.
It’s back to weak onshore flow later tomorrow through Friday.  That means the morning cloud/pm sun routine is back.  I do notice that the marine layer is deepest tomorrow and then thins quite a bit Thursday and Friday, so temps will bounce back slightly.
10:45pm:  Okay, I’m back.  Long range maps have backed off slightly on the weekend trough.  Doesn’t look like the end of the world and probably no chance for thunder either so I’ll take that out tomorrow (if Drew doesn’t do so first at 3am).  Looks like June-like weather will return starting Monday with some sort of ridging next week.  Latest 00z GFS is not quite as sharp with ridging Tuesday and Wednesday.  Earlier runs implied we could hit 90 next week.  The big picture says our generally dry/mild/warm May will continue…Mark

    Interesting article a couple days ago Derek. I don’t necessarily agree with your take on the situation, which I’m sure you remember from discussions here in days gone by, but I have to appreciate the time and effort you put in.
    I do have to nitpick a little bit – I would make sure you brush up on the finer details of some of the facts in there. Make sure everything is correct. For example the strongest hurricane to hit the US was in 1935, not a hundred years ago. The Viking colony in Greenland died out by the 15th century, not the 17th century. The 1816 cooldown was caused by the eruption of Tambora, not Krakatoa (that was 1883). Just to name a few.
    Most people wouldn’t pick up on these details, but anyone with knowledge of climate history would doubt your authenticity with those errors in there. But again good job, I’m only trying to be constructive.

    Thanks Ashley and all who read it. Rob, that took a rediculous amount of time to write. lol Anyway e-mail me at thundr_d@yahoo.com and I will tell you what you want to know. John, I am going to e-mail you the stuff you wanted this weekend.

    Derek is from Reynolds High School.
    I wonder how long it took him to type all of that Lol.
    Was indeed a very interesting, and informative article.

  4. Jerry says:

    Ashely- I didnt write that, Mr. Derek Hodges did. Derek is a senior @ a local HS and this was one if his reports.

  5. ashley watson in oregon city says:

    I thought your “longest blog in history” was very interesting! Where did you get that info for savanah, ga and 1800’s climate for the pacific northwest?? Is there a book I can read?? Also I would like to know more about your sunspot and PDO theories

  6. AtmosphericWrath -Southeast Portland- says:

    Well looks like my forecast from early this morning might be very accurate.
    I’m currently 70.1F
    It’s a perfect day out there!

  7. Andrew---Ellensburg, Wa and Portrland, Or says:

    Up to 72 degrees here now as of 10:55am. On track for another 80+ degree day. Winds gusting into the mid 40’s currently with sustained winds steady at 31mph. Pretty windy and warm day today.

  8. Andrew---Ellensburg, Wa and Portrland, Or says:

    65 degrees here this morning at 9:30am, going to be another hot day today!

    Interesting little fact here:
    Climate Summary
    April 2007
    page delimiter
    The average temperature in April 2007 was 51.7 F. This was -0.3 F cooler than the 1901-2000 (20th century) average, the 47th coolest April in 113 years. The temperature trend for the period of record (1895 to present) is 0.1 degrees Fahrenheit per decade.
    2.09 inches of precipitation fell in April. This was -0.34 inches less than the 1901-2000 average, the 30th driest such month on record. The precipitation trend for the period of record (1895 to present) is 0.01 inches per decade.

    45F this morning compared to the 65F or so yesterday morning.
    Interestingly I have blue skies, no morning clouds, just mid-high level clouds.
    Humidity is 94% so that’s close to having low clouds forming, but I don’t think it’s going to occur.
    Due to this I think temps should be 70-75F today.

  11. Gregg-Troutdale says:

    Down to 52.1 here now, DP 42.4, humidity 63%.

  12. offroadjosh-aloha says:

    hit 85.7 here in aloha. too hot. i like 40 and below(not joking i am a cold weather person) but the sun is nice.

  13. AtmosphericWrath -Southeast Portland- says:

    Perhaps it’s just a delayed surge, but my humidity is also only 56% with little onshore winds at the moment.

  14. Gregg-Troutdale says:

    62.7 here now, DP 44.8, humidity 52%

  15. AtmosphericWrath -Southeast Portland- says:

    63.1F here but appears to me on the east side of town we won’t be or haven’t yet got a significant onshore surge like the valley, SW Washington, or the SW/W side of town has.
    I only have onshore winds 5mph or so now which have decreased from the 10-15mph earlier.

  16. Austin-Ridgefield says:

    Wow went from 84 to 76 from 4:45 to 5:45 it was a light east wind at 4:00 then al of a sudden when I was outside a big gush of wind blew from the Northwest quite cooler air looks like it will be cool tonight, what I thinked happened is that when the cool air was coming in the east wind pushed stronger thats why it took longer for the cool air to get here models are not good when it comes to when wind is going to get to a spot take into fact that the models did not take in the east wind when it made its prediction,looks like the warm air well be gone for a while

  17. Tyler in Vancouver says:

    A full 12 degrees cooler up in Kelso when I left. 66 up there, 78 down here. The winds were very strong (for this time of the year) about 25-30 mph blowing in the cooler air.

  18. Gregg-Troutdale says:

    Thanks for the update Mark!! 82.2 here now, down from 86.5, WSW winds at 14.

  19. John - Aloha says:

    reached 87 around 3:30, now down to 84 with winds picking up from the SW to west.

  20. garron near washington square says:

    Last week, the winds had allready switched NNW @ hood river, this week they are still ESE. Maybe we will not get a complete onshore flow outta this system? I’m going for a warmer tomorrow than they forecast. Maybe 76?

  21. AtmosphericWrath -Southeast Portland- says:

    Thanks for the update Mark.
    Yep cooling has arrived here as well.
    Currently down to 84.1F

  22. garron near washington square says:

    THE COOLING HAS BEGUN IN WASHINGTON COUNTY. My hi has slipped from 86.3 to 84.7, heat wave over…lol The heat low seemed to stall and retro-grade back to the west alil between 12 and 4pm as evident by the barometric pressure drop, still falling at my house 29.94″ and even in Eugene it began to drop slightly this afternoon where it barely reached 70. The heat low never even reached the coast South of Seaside, but it hung on strong for us N. of Eugene all day.

  23. luvrydog says:

    Westerlies have defintely taken over here in tanasbourne…an hour ago I was outside and it was warm with no breeze, went outside again 15 mins ago, you can actually feel a cool breeze on your skin already…good thing I didn’t take the doors off the jeep today, it’s gonna be a cool night ahead after such a warm day!

  24. offroadjosh-aloha says:

    thanks mark. yeah its hot outside(too hot)
