A Historic Coastal Day

SnapshotQuite a day at the beaches…obviously the east wind had no problem making it to the beaches.  Looks like Astoria, Seaside, and Tillamook all hit all-time May highs.  Newport probably did too, the 95° here is from the Airport, which isn’t the same spot where records are kept.

Of course I was disappointed by the "cool" 92 at PDX, but the 96-97-98 at Vancouver, McMinnville, and Aurora make me feel a bit better.

Easterly flow ends soon after daybreak Saturday, replaced by a late afternoon southwesterly surge up the Valley.  I think it’ll be too late to keep PDX below 90, but it’ll be close.

No changes on the thinking Sunday…increasing marine air, but no strong trough in the upper atmosphere means a moderate amount of cooling.  This time of the year a combination of the two could drop us 25 degrees in a day!  That shouldn’t happen this time.

Have a nice weekend…looks like Summer!  Mark Nelsen

    Triforce, hey bud, what’s goin on with western? Are you having troubles over there with the patrons on the site? Western is definetely a different animal than this blog, so ask away if you have any questions or what not, there are plenty of people on this blog that visit western on a regular basis.

    TheTriforce from Silverton says: We are leaving now and when I get back I hope I have someone with experience of said forums to talk to about.
    This is my last report for a while. 68F and high clouds.

  3. Sorry Triforce,
    I’m not familiar with using the Western Weather Forums.
    52.5 for a low last night and starting to warm up quickly this morning.

  4. Clear skies this morning and a nice 50.4°

  5. Jessica says:

    So how’s the temp over there right now? Looks like most of you got lower temperatures… 🙂

  6. TheTriforce says:

    Look, I just need someone to rant to about Western Usa weather that has experience with it’s users. Why doesn’t anyone get that?

  7. TheTriforce says:

    Hellllooooooo? Anyone home?

  8. Derek-West Gresham says:

    Mid 60s now, oh so nice.. 🙂

  9. Down to a NICE 70F now. The cooling feels great.
    I am definitely rooting for convection also.

  10. Yeah,
    Since I posted the wind shifted to NNW (more like I would expect) and I have cooled down to 70.5 and it won’t be long before I’m in the 60s.
    Here’s rooting for convection. We have still have a warm airmass over us.

  11. High today 84.8°
    Currently 73.8°
    DP 50.5°
    RH 45%
    Winds SSE 0-5

  12. It figures.. No sooner I post about all locations west of the West Hills reported easterly component to their wind that the Hillsboro Airport goes NW@8 trying to make a liar out of me 🙂

  13. Surface gradients as of 8:00 PM
    PDX-DLS +2.0 weakened slightly

  14. HIO Phil,
    It’s possible most of the metro area could have seen variable winds shifting from one direction to another. I also believe in Hillsboro and other locations west of the West Hills that you get a bit different wind direction or wind behavior due to the proximity of the West Hills and Coast Range. Just yet another neat micro-climate feature we have in the PNW.
    As a matter of fact check out the Mesowest observations map for the north Willamette Valley and PDX metro areas.

    79.0 here
    I thought we would cool off a bit quicker this evening. So far that is not happening.
    Surface gradients as of 7:00 PM
    PDX-DLS +2.2 decreased from the peak of +3.7 at 2:00 PM.

    [IR Loop]
    http://www.atmos.washington.edu/~ovens/loops/wxloop.cgi?ir4km_enhanced+12
    Shows a fairly sharp cold front out near 134 W. I am having some thoughts that if we rebound to the 80-85F range tomorrow again that as the cold front approaches maybe some convection fires out ahead of it? Seems like a very slight chance and too early to tell right now, but I wouldn’t rule it out completely.

    Sorry for the double posts upsets you but I need to fill in this last detail.
    I have tried to email someone who has been abused about my expereinces Wxdude but he was banned for no legit reason and I can quote my words to you as I would like an ‘outsiders’ opinon who has been there before.

  16. TheTriforce says:

    I would like someone to email about problems and for cofort about a Western Weather that has had expereince there because the Mods never do anything.
    My email is at KyleHillx@msn.comm for anyone who is willing to listen. Please do not abuse my email either.

  17. Triforce,
    It sounds like your themometer is in a pretty good location. You might find that if it was farther from your house that your overnight lows might come in a couple of degrees lower, especially in the winter with no wind.
    I had a high of 86.8 today.
    Currently 80.2
    DP 56
    RH 43%
    and strangly, a NE to East wind. The airport is showing the same. Gradients are still onshore. Any opinion Rob?

  18. TheTriforce says:

    TheTriforce: Here is where I am going from Monday-some of Wednsedayhttp://protophoto.com/subject.html?subject_id=241&start=40 So I won’t be posting here during that time-frame unless God gets it together and lets me have some internet access to do so which I would like.
    By the way: I do not own the images of the mentioned site and they are copyrighted by the respective Authors. So pleeze do not steal. Thankz.
    Now does anyone want to hop in my Dimension Machine and come along with our real car? I will give the keys to the first person with a valid Drivers Licesne who speaks up 😀 (Fingers keys)

    The Yakima river is flooding here currently in Ellensburg, Wa. Many of the roads along the river are now completely under water and the water level is still rising. I will link some pictures to here in a little bit.

    TheTriforce has 2 questions.
    quoted by Punx.
    “Triforce,
    You don’t say how far the thermometer is from your house so I can’t say. As far as the height goes it sounds ok. The main thing is to keep it out of the direct sun. If it’s on top of the roof of the shed, I would move it. It being wireless is good because you don’t have to worry about what to do with the cabling. I think official stations are supposed to be measuring the temp at 2 meters above the ground or at something like that. If someone knows the correct height feel free to correct me.”
    -Punx
    My therometer is right under the awning and about 3 or so feet from the house.
    2nd question below.
    I am also going to Pendleton OR tomorrow thru Wednesday as dad has taken the week off except Sat. We want to see the Underground tour of how the chiness lived I’ve been there when I first started High School around the early 00s but I haven’t been back since.
    Does anyone see anything exciting weatherwise there?
    Unfortunatly there looks to be no exciting weather except a low of 43 Wed which isn’t exciting for them but cold compared to now. Does anyone see anything exciting weatherwise?

  23. With all that snowmelt the water must have been cold!
    This is looking like a very dry May over here. I’ve had .17″ of rain this month and looking at the long term models, outside of Tuesday-Wednesday next week, I don’t see much chance of precipitation the rest of the month. It’s a good thing there’s lots of snowpack.

  24. …correction….should read… a friend in the Colton area reported for friday and saturday 102 on the south side of his place, with 98 on the thermo next to the creek

  25. …has anyone stumbled upon this cam before?:http://www.virtual-oceanside.com/surf_cam.asp
    …has anyone ever been around an old UPI or AP teletype machine?…..
    ….weather report from up here..looks like the highest temp here this nice hot spell was 90.1, sensor located 6 feet above ground under the eves on the north side away from the windows….
    …a friend in the Colton area reports 102 on the south side of his place, with 98 on the thermo next to the creek….
    ….curently, a fine comfortable 72.4…..

  26. Triforce,

  28. …..it was very interesting on the upper Clackamas the last few days…snow melt making the river rise fast enough to watch…rafts and kayaks hung up on rocks, Austin Hot Springs covered by water…
    the river at one point was rising an inch every couple hours…kind of like what one would expect from a December rain….

    Well with the brief taste of Summer we have been experiencing it seems “big spider” season has began. What do I mean by this? I was sleeping nicely at 6:15 AM when my Cat woke me up meowing. I walk out into the main room and what do I see on the wall a huge brown spider…. That was the first time the kitty has done that, so I guess we have a spider alarm now or something lol. I’m glad because I wouldn’t want that thing loose running around in the house.
    My morning outlook….
    7:00 AM observations reveal low clouds/fog along most of the Coast. As Tyler previously mentioned they have pushed up the Columbia River to about Kelso, but they haven’t made it to Scappoose and I doubt they will make any further progress. All valleys locations from Eugene north are reporting CLEAR skies. Throughout the entire area very light or calm conditions are present. I don’t see any good push of marine air occurring right now, but overnight we had some which has us all 3-9F cooler this morning.
    [IR Loop]
    http://www.atmos.washington.edu/~ovens/loops/wxloop.cgi?ir4km+12
    Looking at IR loop shows a general southwest flow aloft with streams of high clouds possible at times. A system offshore near 147 W is responsible for that.
    Surface gradients as of 7:00 AM
    PDX-EUG +0.3
    Flow has gone northerly, so any cooling we did experience from the south overnight has ended and do not look for any today.
    PDX-DLS +3.2
    Onshore gradients have increase since last night, but remain hovering near 3mb. This is filtering in cooler ocean air, but not a massive surge.
    So this morning it looks like relatively wall-to-wall sunshine with very light or calm winds. Due to things we are not seeing the rapid increase in warming we did this past morning. Given all of the above conditions I will go with 82-86 today.

  31. Tyler Mode in NW Vancouver (Hazel Dell) says:

    Low clouds have pushed as far as Kelso/Longview this morning…and the high clouds are filtering the sun here. I actually didn’t mind the heat, but I didn’t have my AC in yet, so didn’t have a real place to get a little break! Its in now…but we know with Memorial Day next weekend, rain is sure to fall!

  32. TheTriforce says:

    Quoted by Punx:
    “Ideally your thermometer should be about 5-6 feet off the ground and out of the direct sun unless heat shielded. It should be as far away from any structures as possible, but I know that’s often not practical, so the north side of a structure is best. Keep it away from anything that will retain or reflect heat such as asphalt or concrete. If you have a thermometer that is part of a weather station buy the heat shielding if you can afford it. The best nowadays come with a solar fan as part of the heat shielding.
    For instance, my station thermometer is 5&1/2 feet above the ground on the north side of a fence about 25 feet from the house and heat shielded. The fence is in partial shade”
    Sincerely,
    Punx.
    The Triforce says:
    My Therometer is on the north side of the house at the top of our shed. There is room for one and a half regular sized people to walk through and there is no concerete on the ground. Is this too close to my bedroom window which could give out heat?
    My therometer has an outdoor range that my main station connects to wirelessly: The one on the shed. Plus, I also have in indoor temp gauge as well.
    I am sitting at 70F right now MUCH better then the awful 96F today. I helped dad with washing windows by shutting the water off and misc stuff this afternoon.

  33. 75.0 here
    Onshore flow just weakened a bit.
    Surface gradients as 10:00 PM
    PDX-DLS +1.9
    Any weakening trend to the onshore flow past 10:00 PM does not bode well if you want significant cooling (10-15F) tomorrow.
    PDX-EUG -2.3
    So perhaps some slight cooling overnight coming from the heels of very light south winds. I wouldn’t expect much.
    Given this information I am going with 83-86 tomorrow. If things look different by morning I will adjust accordingly.
    Good night all.

  34. My high today was 93.1°
    Currently 66.2°
    DP 50.2°
    RH 56%
    Winds are calm

  35. Robert in Vancouver says:

    Rob, you’re probably right. The closest station to me on the Mesowest map showed a high of 94 today, although I did see a number of readings of up to 103 around me on Wunderground’s weather stations. I’m further inland than the Mesowest location is from the River, so I wouldn’t be surprised by a higher reading at my location by 2-5 degrees, but I think it just means that I’m going to have to construct some type of radiation shield for the thermo-hygro sensor to get a more accurate reading. It’s a new unit, so it’s a work in progress.

  36. In my opinion a reading of 101 yesterday is very believable given many locations where in the upper 90’s. However today being that I don’t think anyone exceeded 97 a reading of 100+ seems unlikely.
    Onshore flow remains quite weak with PDX-DLS only +2.2mb. I noticed almost every coastal location besides Astoria are reporting CLEAR skies, even North Bend and Brookings. Seems a little unusual given the heat low/heat axis is well inland with 12+ hours of wind reversal well under way. Yet there does not appear to be very extensive low clouds/stratus along the Coast. The wind at my house is dead CALM. Around the metro area and valley all the way down to Eugene it’s a very light W-SW wind which isn’t doing squat to cool us down much. I’m wondering if perhaps we rebound tomorrow into the 81-85 range rather than near 80. Even Coastal locations are only seeing SW-W winds 2-8mph. If we were to see a good marine push the winds would normally be 15-20+mph…. So I am considering that we could be near the mid 80’s tomorrow due to this.
    Any thoughts?

  37. Sir Triforce,
    Ideally your thermometer should be about 5-6 feet off the ground and out of the direct sun unless heat shielded. It should be as far away from any structures as possible, but I know that’s often not practical, so the north side of a structure is best. Keep it away from anything that will retain or reflect heat such as asphalt or concrete. If you have a thermometer that is part of a weather station buy the heat shielding if you can afford it.

    Sincerely,
    Punx.

  38. TheTriforce says:

    Is my therometer in the right spot also? If not maybe I should move it to a better place?
    quoted by Robert: “I’m toying around with the final position of my thermometer I mounted last month, and know it is running about 2-3 degrees hotter than reality because of its positioning, but I’m showing 102.5 outside right now.”
    I showed 101F yesterday but am not sure if it’s bogus.

  39. Nof out near Carlton says:

    Temp started falling rapidly shortly after 5pm, down to 81.8 now.

  40. Well…The NWS forecast discussion says the record high for Hillsboro is 90 but the Western Climate center data says it is 97. The 18th’s record is 90 so I think they got the wrong day. If not then it is a record for Hillsboro today with a 92 at the airport.
    Hey, I can still see snow on the higher peaks of the coast range, probably South Saddle Mountain. So It’s mid May with Temps in the upper 90’s and still some enough snow has survived to be seen 35 miles away, amazing!
    Looks to me like SW flow aloft is starting to increase.
    Currently 87.1
    DP 55.
    WSW wind. 1-10.

  41. Paul(orPbo9) says:

    high here noportland
    96º

  42. PaulB/Eugene says:

    95F in Eugene…highest temperature ever recorded in May at Eugene airport.

  43. Derek-West Gresham says:

    Topped out at 93 here. 95 at PDX

  44. I peaked out at 93.6
    I am quite satisfied how my forecast I called for even yesterday ended up turning out for today. The way this early morning was progressing it wasn’t a hard call.
    It looks like most of the metro area did hit 90-95 or perhaps a smidge higher in a few locations.
    We probably have all peaked due to a slow increase of onshore gradients and the accompanying west-southwest breezes.
    Surface gradients as of 5:00 PM
    PDX-DLS +2.1
