A Few Days Off

Snapshot Tonight should be the coldest night so far this season.  You can see that frost will be a bit earlier than normal for most places on this graphic.  The text is quite small on this one, so click on it to get a larger view.  The data comes from Oregon Climate Service and is from the 1971-2000 30-year average.  As I recall from WAY back in the 90s, the frost dates used to be a bit earlier.  I thought Hillsboro used to be in late October and PDX was more like November 8th or 2nd, or something along those lines.

Not a whole lot to talk about tonight.  A surge of very dry air has moved south, out of Canada and into Eastern Washington and Northeast Oregon.  Dewpoints crashed into the teens in E. Washington during the day with a gusty north and northeast wind.  That very dry air just nicked The Dalles late this afternoon.  Notice the "moist" west wind stopped for an hour or so before resuming.  Dewpoint dropped at the same time.  With a switch to light easterly flow tonight and tomorrow, I think we'll see dewpoints drop some here west of the Cascades tomorrow.  Maybe a bit closer to 30 instead of 40.  This should keep fog away the next two nights.

We left rain out of the 7 day forecast since there was no one specific system that is forecast by all models to move through the Pacific Northwest.  But definitely close calls on Tuesday and/or Thursday/Friday.  We'll see.  Other than that the weather looks very slow.  Rob Martin, our morning meteorologist may post a bit next week, so treat him like family!  Mark Nelsen

    Here’s the requested follow-up to my post from yesterday, which I’ve provided to the NWS link. No pictures of the event itself, but I’ve provided them some photos that I took today of minor damage in the orchard.
    My location is 20710 SW Mountain Home Road, Sherwood (NE side of Chehalem Mt facing Scholls and Hillsboro). About 2:00PM yesterday afternoon we were between heavy showers and had no appreciable wind. From inside the house I heard a roar coming from the west (my view was initially blocked by trees and barn). Within a few seconds, a rotating column, clearly denoted by filbert leaf debris, came out of my neighbors orchard, passed over a large puddle of standing water, (again showing very rapid rotation as the water was sucked up) and headed east. The column of leaves was taller than the Douglas firs on the eastern edge of my property (over 100 feet tall). The suspended leaves in rotation were about 150 feet wide. Fortunately it did not pass over any structures. Only minor damage in the filbert orchard but it certainly got my attention! One of the more interesting aspects was the pattern of leaf removal. The orchard should have a fairly uniform layer of fallen leaves and there is a notable absence along the event-path.
    A neighbor, who left about 10 minutes before the event, said she saw a black wall-like cloud to the west with what appeared to be two funnel-like appendages. She’s from the Midwest and it looked tornadic to her…..

    I wish I could make it to the meeting this year. I have been there the last two. Will be up in Bellingham later this week, though.

    12Z GFS shows us getting brushed with some arctic air the beginning/middle of next week.
    A couple runs of the Euro have hinted at this solution too, although last night’s 00Z Euro did not.
    Possibly another Halloween arctic intrusion? It would be the 4th time this decade.

    Hey, is the winter weather meeting this Friday at OMSI? There’s been no buzz on the blog about it…

    Charles, I was thinking the same thing, i was waiting to hear from the NWS or hear about a severe warned cell somewhere. I’d be interested to hear more about this…is there a ground track? Any phone pics or anything to confirm this tornado?
    Please respond Mt. Home so we all can find out more about this…I know everyone here would be very interested!!!
    This is a very important stat for the NWS if I may add.

    Mt Home Hillside Farm…
    You posted the following earlier this afternoon:
    ————————————————-
    A cold air funnel, on the ground, passed through the lower half of my property, 750 feet NE side of Chehalem Mt heading east about 5 minutes ago. Roared out of my neighbors hazel nut orchard….never seen (or heard) anything like it….

    ————————————————-
    First of all…if it was on the ground, it’s no longer a funnel cloud….rather a Tornado! If it was indeed a tornado, we here at the NWS in Portland would really like to know more detail about that incident!! If you’re sure that it did indeed touchdown, can you offer up anything else?
    If you need a point of contact, use the webmaster email link on the bottom of our homepage… http://www.weather.gov/portland
    Thanks!
