Bright Fall Colors

DSC_6427  Don Best from Rockaway sent me this picture today.  He's a prolific photographer.  There are several other photos in the photo album to the left.  It's been a great Autumn for colors, possibly due to the consistently chilly nights and warm days?  I'm not an arborist, so I don't know, but I do know that I have been able to get outside regularly before work most mornings since Labor Day.  I don't think we've had more than 3 days in a row that were wet or cloudy this season.  I got quite a bit done at home the last few days with just perfect weather.  Part of that included keeping a close eye on an old still smoking slash burn pile on property right next to mine.  It never got beyond that, but I was a bit nervous early Sunday morning when I could see sparks being blown around by the east wind!

Moving on…a weak upper-level disturbance is passing over the middle of Oregon right now.  It's headed off to the northeast…too bad it isn't July because it would have been a prolific thunderstorm producer.

A weak cold front is gradually approaching from the west, but models say it never reaches us due to a new and deep upper-level trough developing in the eastern Pacific around 140W.  This trough sends waves of moisture along with surface lows north around 130-135W Thursday and Friday.  That's too far west to give good southerly gradient along the Coast, but is close enough to turn as back into easterly low-level flow over the metro area from tomorrow evening through Saturday.  IF we get significant sunshine Thursday, the combination of that easterly low-level flow and warm southerly flow above could push our temps up close to 70 degrees.  That's near record territory.  Too much cloud cover though and we stay in the low-mid 60s.

It still looks like November starts just like it should…wet.  I don't see any big & windy storms early next week, but compared to the last few weeks it looks much more active…Mark Nelsen


Lets See Some Snow…and Rain in the Valley

Cascades7day

Good early morning all.  So the weak upper level trough is moving a bit to the north, into our area this afternoon into tomorrow.  This will affect the coast cloud layer a bit, with morning fog and cloudy skies for the day before it moves inland on Wednesday.  I don’t see a strong chance of precip with it before the ridge rebuilds as the trough moves east.  It’s a quick move.  As Halloween comes we will see a long filament trough move in, pushing the ridge out of the area, creating a wet forecast.  (I also see a hint of a cut off low and kicker trough set up, up stream…yay).  Yesterday it looked like we might see some showers late Thursday, but now I think it will hold off just in time for trick-or-treating. 

I am happy to see the possibility of snow for the cascades late this weekend into early next week.  I am getting the ski jitters! -Rob Martin
