Snapshot Looks like easterly gradient is picking up quickly this evening as high pressure settles east of the mountains.  Still looks like maybe 8 millibars from PDX-DLS by mid-morning tomorrow.  Obviously fog is close to developing with a low temp-dewpoint spread at this hour.  This fog should be quite shallow with easterly wind developing just above the surface just about everywhere in the metro area by daybreak.  I think the increasing wind will also keep us fog-free east of I-205 tonight.

This won't be one of those wintertime events where the wind sticks around for days and days.  A front passing by to the north Thursday lowers pressures to the east pretty quickly then, killing the wind.

Long range?  There seems to be a tendency in several different models to want to bring troughing over the Pacific Northwest, a pattern similar to last winter.  00z GFS looks quite a bit different though.  It IS a safe bet that mild and warm weather continues at least through next Tuesday.  Beyond that though you should just roll the dice.  Mark Nelsen

    OH MY GODDESESS! Look at our October rainfall status!!
    Precipitation Highest in 24hrs 0.31 in / 0.8 cm 0.03 in / 0.1 cm 0.00 in / 0.0 cm
    Monthly Total 0.59 in / 1.52 cm
    Snowdepth 0.0 in / 0 cm 0.0 in / 0 cm 0.0 in / 0 cm
    I had put the words Highest in 24hrs.etc myself plus reformatting it a bit as it would look like a mess and make your eyes bleed. 😦

    Considering how this October has been (except for the first few days which were wet) I’d guess the 7day has been changed A LOT.
    C’mon 00z give us a trough, a low slamming us, pineapple express, polar vortex moving southwest parking itself over Bellingham, just something different.

  5. HIO Phil (Punxsutawney) says:

    Tri-force,
    It would be interesting. You could save the 7 day pics and keep track of how they turn out. I’m not sure we want to point out when Mark’s wrong though. Might get banned from the blog, lol.
    Currently 46.5 DP 39.

  6. TriforceofEternity says:

    It would be nice if we can go back in time to look at Marks 7 day planner and see how many times things have changed. All the october 7 day forcasts.

  7. TriforceofEternity says:

    50F here after a high in the low 60s.

  8. HIO Phil (Punxsutawney) says:

    Wouldn’t surprise me at all Rob. The only reason I’m feeling contrary at the moment is because rain on Halloween after a sunny dry week would be perfect irony.

  9. High of 65.7, Today. Temp dropping 1.3 degrees every hour right now. light wind right now… anywhere from 1mph – 4mph hit 18.5 at 3:36pm. Currently 57.9

  10. HIO Phil (Punxsutawney) says:

    High of 68.1, Low of 31.7 Today. Temp dropping with no wind. Currently 53.3
    Looks like the 18z tones down the amount of rain but still has plenty starting just before Halloween. I don’t see low-mid 70’s next week either. Still quite mild until the rain starts.

    It’s 70 in Hillsboro right now. A pretty good swing for one day, 30-70.
    If the 12z GFS comes to fruition, we will be looking at the possibility of record highs next Tuesday-Wednesday. It will be the warmest late October I can remember. I noticed that the records for those days in Hillsboro are from 1987 if anyone is looking at analogs. At least it gets very wet right after that, and that’s been fairly consistent in the models.

    Scratch what I said yesterday guys. I will be there on Friday (OMSI) along with my bro Josh from Everett. Look forward to seeing some of you again and meeting some more of you. Hope everyone can make it.
    No wind here out by Oregon City.

    Back for the time being.
    Thanks, Luvry. A bit better…. all from feeding birds outside earlier. It only took something simple like that.
    [Surface gradients]
    As of 1 PM
    PDX-DLS: -6.5 Peak -8.0mb at 10 AM
    TTD-DLS: -7.0 Peak -8.4mb at 10 AM
    Cross cascade gradient
    OTH-GEG: -13.0
    Corbett peak gust 49mph
    My peak gust 38.2mph
    12z WRF-GFS extended looks like more of the same. It looks like the pattern tries to change, but what do you know another stinking ridge develops near 145-150 W moving towards us I believe. I am not confident on any pattern change for at least the next 9-10 days.

  16. Punxsutawney (aka HIO Phil at work by Sunset High 280' elevation) says:

    Breezy over here at times, occaisional mild gusts scattering the leaves around. The sun feels nice and warm.

  17. Andrew Johnson (Silverton) says:

    Winter storm developing right now over the Central Plains. Its not far off guys!

  18. IceKeeg - workin' in Tigard says:

    Very light breeze – nothing much, but every now and then we get a decent gust that sends a shower of leaves everywhere. Really beautiful. Also, with our dry, sometimes coolish weather we’ve been having, I’m guessing that our Fall colors should be more vibrant than we normally see. I don’t know if that’s actually the case, that dryer weather maintains the colors better than a soggy fall. I could google…but…nah.

    Nothing here.

    ….mighty breezy here!…56.1

  21. luvry (in tanasbourne) says:

    I dunno if anyone has got a sneak peak at the 12z GFS but it sure looks like fall will arrive right around Halloween. Nothing MAJOR at this point but from hour 174 all the way through 372, there are consistent storms coming through, November may start off wet for sure! The GFS has been hinting at getting the zonal flow goin around this time frame off and on for awhile now, hope it happens!
    Rob, feel better buddy!

  22. Atmospheric Wrath -Far S.E. Portland- says:

    Well very dizzy now.
    I will try to be back for the 10 & 11 AM gradient updates, but if not someone else feel free to do so.

    Seeing the pressure has slightly fallen at The Dalles though leads me to believe the peak is near.

    Darn. No rain and too much sun. 😦 I was hoping some clouds for a few days in between.
