Hot & Windy

Check out the fires exploding across SW Oregon.  Medford's 5pm relative humidity was 5%!

A fun weather day today!  A start with all the windows closed and the heat cranking, but mid-morning the windows are open and the wind is blowing, and then by late afternoon it’s a very warm wind and leaves/branches are flying all over the place in the metro area. 

Good times at the beach too…a bunch of KPTV employees had plans to visit the beach early this week and I told them GO!  The weather didn’t disappoint;  90 at Newport, 88 at Tillamook, 93 at North Bend!  That only happens once or twice a year at best. 

Obviously back here in the metro area we were held back by the “cooler” air coming through the Gorge.  The Dalles was 82 today.  The forecast tomorrow is 90 or so.  So keep in mind that the airmass itself warms a few degrees tomorrow, up to +24 deg C at 850mb, PLUS, the low level air coming in through the Gorge should warm 8-10 degrees.  That’s why I kept 94 in the forecast for tomorrow, instead of panicking and saying it would only hit 89 or 90.  At the very least, we’ll finally get that 90 degree day to push us over the yearly record of 23 days that is currently tied.  Along those lines, I think tomorrow will PROBABLY be the last 90 degree day of the year.  Yes, I know, it can still hit 90 in early October, but it gets tougher to do with such long nights and weak sun at the end of September.

As for wind, I see the gradient is back up over 6 millibars again; very healthy for late September.  Peak gusts were in the 40-50 mph range out in the western Gorge, and 30-40 mph in the eastern metro area today and should stay that way through tomorrow morning.   We don’t totally lose the easterly wind until early Wednesday morning though.  We actually get a good onshore push Wednesday afternoon/night, so with low clouds Thursday morning, we’ll have a tough time getting much above 70-75 that day.

September is going to end dry and warm…more ridging for the last few days of the month…enjoy!  There are plenty of storm-tracking days waiting for us November through February…hopefully.

    18z shows freezing temps in vernonia early next week, some outlying areas around here might see frost and mid 30’s if we get a clear night, cool and dry, not to bad, then 18z shows us into an every so often trough type pattern.

    95 in tillamook and that is a new record

  3. muxpux says:

    93 here in Kelso. i see PDX is at 92…and got .02″ of rain today?! haha.

  4. Looks like PDX has hit the 90° mark….

    90.8F here…

  5. 90.4F here….east winds have abated some…

  6. muxpux says:

    wow. Kelso skyrocketed to 90!

    that wind picked up outta the SE, and temps reacted.

    in an hour and 20 minutes the temp shot up 15 degrees…humidity went from 44% to 24%

    now thats a spike!

  7. Tyler says:

    93 in Tillamook, to the south, Newport is down to 75 after hitting 79 around 11 this morning. Wind is now westerly.

    The visible sat shows no low clouds until you reach the northern Cali coastline.

  8. Hit my highest gust of the day (22mph)….

    88.0F…RH 18%

  9. k5mitch says:

    85.4 the wind is subsiding some what.

  10. Rob "Wrath" S.E. Portland says:

    PDx 87F. 90 is a lock! and the new record will be set today. It’s about time to celebrate 🙂

  11. Rob "Wrath" S.E. Portland says:

    81.7F here.. Although offshore gradient are waning there may be too much mixing to reach 90 here today.

  12. muxpux says:

    Kelso: 73, 50% humidity, calm winds.

    Astoria: 83, 29% humidity, E 10

    this “event” is a “bust” up here…lol

    Coming back down 84 this afternoon the heavy wind wasn’t until between probably 150th and 160th, then it really started pulling on the car. The temp. also dropped about 3-4 degrees between there and Fairview Parkway.

  14. Tyler says:

    The GFS shows the offshore flow completely ending around 10 AM tomorrow, but it looks like it makes a return over the late weekend. Nothing strong though.

    GFS just knicks us with some troughs, lowering heights, bringing onshore flow, then it’s back to warm and dry. No major systems show in the next 16 days. The euro shows a much deeper trough moving in mid-next week.

    • Rob "Wrath" S.E. Portland says:

      Nice analysis. 12z GFS looked very ridgy with just some dents in it at times as you described. Personally I’m rooting for the ECMWF to be correct.

  15. Tyler says:

    82 degrees now with a sudden burst of east winds, not strong though.

  16. Rob "Wrath" S.E. Portland says:

    Surface gradients
    As of 12 PM-Current|Hourly Change
    PDX-DLS: -6.2mb | 0.8mb Decrease
    TTD-DLS: -6.2mb | 0.5mb Decrease

  17. Up to a warm 85.1F here…Well above yesterday at this time…East winds continue..

  18. Rob "Wrath" S.E. Portland says:

    Air mass is much warmer today as I see Horse Creek 3,402′ is sitting at 79F which already exceeds yesterdays high temp of 78F.

  19. Rob "Wrath" S.E. Portland says:

    78.4F here with continued strong and gusty east winds.

    New peak gust @ 10:33 AM 41.9mph

    Surface gradients
    As of 11 AM-Current|Hourly Change
    PDX-DLS: -7.0mb | 0.1mb Decrease
    TTD-DLS: -6.7mb | 0.6mb Decrease
    It appears gradients have reached their peak. My projection of 6-8mb was right on par. In fact yesterday I told my Father -7.4mb was my target #. No lie on that. 🙂

    Well we do have one large Elm Tree branch down, but it isn’t nearly as bad as I was expecting. I would have to say this is by far the strongest Summer-like east wind event that I can remember.

    • Rob "Wrath" S.E. Portland says:

      Oh I forgot to mention that we never lost the east wind out here last night. My low temp was 71.0F

  20. Tyler says:

    No east wind here. Temp is 73.
