Strong Evening Wind?

SnapshotSnapshotInteresting development offshore this afternoon.  A clearly visible tightly wound area of low pressure is located just offshore of Newport at 3pm and headed northeast.  MM5 and our WRF model take it to Spokane by 5am, passing very near the metro area.  Our model shows 6-7 millibars pressure difference between Eugene and Portland around the 8-10pm timeperiod.  This could produce southerly wind gusts to 40 mph or so.  More interesting is the peak gust to 41 mph right at 3pm observation time at Eugene.  That’s pretty strong for Eugene.  They often don’t get gusts much more than that with the good winter storms.  I have a feeling Albany-Woodburn may see gusts over 45 mph by dinnertime.
11pm Update: 
That was a fun little system.  Peak gusts in the metro area were around 40 mph.  I see peak gust at PDX was 43 mph.  The new wind speed sensor for the ASOS system there has NOT been installed yet, although Eugene’s has.  The NWS is installing more accurate windspeed sensors at our local sites over the next few months.  It basically boils down this; the ASOS units installed in the mid 1990’s recorded a longer "peak gust", which gave us lower peak windspeeds the last 12 years.  The new instruments will take us back to the "2 second peak gust" measurement.  A prime example is that no station in the Valley recorded a peak gust above 58 mph in our big December windstorm.  Yet home weather stations recorded 60-70 mph gusts or even a bit higher in spots.
Much slower weather tomorrow and then a juicier system moves in later Friday.  The long range picture (the rest of April?) is a succession of troughs and weak ridges for plenty of showers/rain.  The dry periods will be short lived…Mark

    Most of the day was dry,,,with a high of 62 at pdx. But light showers are coming into the area. That event in Dallas texas was interesting,,,but looks not to have been that bad overall.

    First off, I hope no one was injured. Secondly, Rod Hill on 2 just said this storm was going to wind up into a nor’easter, and move up the east coast on Monday….exactly one week before I am due to be in Washington DC!!!!!!!! Not fair, I would love to be there for one of those!!!!

    Quite a day they’re having there in Texas…or bad day depending on where you’re at I guess.

    baseball sized hail reported

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

    Holy shit, tornado heading towards downtown Dallas, Texas. Could be tons of deaths, pray for them

  7. wendy-silverlake says:

    Does the front dying mean less rain, more rain, or it will come in later than expected. Any predictions for Sunday about 12:00. Got an outdoor birthday party planned.

  8. Derek-West Gresham says:

    the front is dying, I’m impressed actually. PDO for March dropped to -.36 I think so we are going down again.

  9. 32 snowwish From Silverton OR says:

    Wow portland’s temperature thing says 61 which is one degree above Mark’s forcasted high of 60 take a look and it’s only 2:20 or so

  10. wendy-silverlake says:

    where’s the rain?

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

    Looks like the old Farmers Almanac has been pretty darn close this year, this is what they said:
    “Winter will be a bit colder than normal, on average, with above-normal snowfall. Precipitation will be below normal in Washington and above normal in Oregon and California. The heaviest snow will fall in mid- to late February, with other snowfalls in mid-November, early to mid-December, and early to mid-January. The stormiest periods will be in early and mid-November, mid-December, and mid-March. The coldest temperatures will be in early December, mid-January, and mid-February.
    April and May will be cooler and wetter than normal, on average, with the stormiest period in mid- to late April. The first half of April will be warmer than normal, with below-normal temperatures most of the time from the latter half of April through May.
    Summer will be slightly cooler and drier than normal, on average, with the hottest temperatures in mid-July. Other warm periods will be in mid-June and mid- and late August.
    September and October will be wetter and warmer than normal, on average. ”

  12. Derek-West Gresham says:

    Hey Gregg, I agree in part. Cool and wet for a while, I don’t know how long…but eventually becoming dry and hot for an early summer. But we should also move into fall pretty quickly with a cooler mid to late summer, maybe even more rain. 🙂

  13. Gregg-Troutdale says:

    Looking at everything, I’m beginning to think we will have a cool and damp remainder of spring, possibly lasting into this summer as well. Any thoughts??

  14. offroadjosh-aloha says:

    wait nvr mind yeah its right now

  15. offroadjosh-aloha says:

    No its not….

  16. Derek-West Gresham says:

    The thunderstorm is the right way today!! lol

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

    Sitting at 63 degrees right now, might be able to push a bit higher before the cloud cover hits me.

  18. kirk says:

    Is it January? It is a very wet 41.7 up here. Went skiing Tuesday best conditions I have seen in a while. Knee deep powder in Heather Canyon.

  19. offroadjosh-aloha says:

    Derek i guess you and i both are weirdos. LOL

  20. offroadjosh-aloha says:

    Never mind… You already answered it. Looks kinda different, its opposite of what it should be. You can’t flip it?

  21. offroadjosh-aloha says:

    thanks for the update Mark! BTW why on you 7-day forecast on Saturday the is a t-storm icon, (i don’t know if you wanted it that way or not) its like upside down or flipped over or something.

  22. Sean (Lebanon, Indiana) says:

    It was quite an interesting evening last night, had two tornado warnings issued for my area last night. I was lucky enough not to suffer any damage from either of the twisters which spawned within about a 7 mile radius of my house.
    Here’s some pictures of the twisters..

  23. Antipex (SE Gresham) says:

    We got some good 30-40mi/h gusts here – one of them really shook the house.

  24. Derek-West Gresham says:

    It bothers me when its switched around. haha Maybe I am a weirdo. 🙂
    South wind kicked in here but was nothing compared the easterlies which were never THAT strong in the first place. Musta been unlucky.

  25. Gregg-Troutdale says:

    Thanks for the update Mark. Quite the spring wind event this evening. Good E wind that changed very quickly to strong SW wind.

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

    haha, nice call Derek

  27. Mark Nelsen says:

    How did you know it was backwards? Only a true weather geek would notice that. Ever since I noticed our thunderstorm icon looks like Minnesota, it’s been bothering me. That’s why it’s reversed.

  28. Derek-West Gresham says:

    I see you threw in a backwards thunderstorm on Saturday Mark..I dont see it happening but thats just me. 🙂

  29. offroadjosh-aloha says:

    hit 41mph in aloha earlier

  30. Cherie_in_Vernonia says:

    Looks like the worst is over

  31. John - Aloha says:

    barometer fell to 29.65 shortly after 5pm and now is rising 29.69

  32. John - Aloha says:

    wind gust to 37 mph a few minutes ago, wind averaging 20 mph

  33. Paul says:

    Very windy here, near N. Wilsonville
    exit. Several gusts probably over 45mph. 2′-3′ Douglas Fir limbs down.
    Wind started all of a sudden with a
    HUGE long gust. Very interesting.

  34. Cherie_in_Vernonia says:

    Seems like many of the stations are out of service on Trip Check

  35. Sandi (Wilsonville) says:

    Wind has really picked up here in Wilsonville. Aurora Airport shows a gust of 32 so far.
    I need to get our wind guage replaced! :o( Heading outside now to batten down the hatches!!

  36. wendy-silverlake says:

    Does anyone know what direction the rain is coming from on Sunday. Is it coming out of the north or south. Got a 3 year olds birthday who really wants a baseball game. I know Mark is showing rain in the morning, but if the rain is in Portland in the morning just curious if it will be gone here by then or we’ll get it in the afternoon. If anyone has any ideas I sure would appreciate it.

  37. Jordan says:


    That line of showers Se of Salem jsut maade alot of lightning

  38. Cherie_in_Vernonia says:

    What did you see Derek?? Was gone by the time I got there

  39. Cherie_in_Vernonia says:

    Sorry Sean….won’t let me go there :0(

  40. Cherie_in_Vernonia says:

    A picture is worth a 1,000 words. Look @ the camera lens @ Mt St Helens :0)

  41. Mat says:

    Thanx for the update Mark. Looks quite impressive for this time of the year. I’m hoping for higher gusts than that but beggers can’t be choosers.
    Bring on the wind!!

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

    Thanks for the update Mark!
