ECMWF Weekly Maps: Ridging Continues?

Twice a week the ECMWF is run out to one month and we see an average of the 500mb heights for the week from all the ensemble members.  I just looked at last night’s run.  Of course you can never read too much into these maps, but sometimes they give us a general idea of what might be ahead.  In this case it appears some sort of higher than normal heights (ridging) wants to stick around through at least mid January.  We’ll see.

    Avg temp in EUG through 26 days of Dec still stands at 32.4. If we average high 37 and low 31 through the end of month (looking outside that seems reasonable) then we would end up with 32.6 for average, coldest Dec all time and #7 all time for any month.

    Any chance for snow flurries or light freezing rain tomorrow in the Hillsboro area due to the cold temps and inversion, plus the little impulse rolling through?

    Some nice changes showing up on the 00Z GFS operational run tonight. Omega ridge in the Gulf of AK, another ridge in the SE USA, arctic airmass in southern BC. I realize it’s after the resolution change, but hour 324 shows a snowstorm from Portland to Seattle. At least the long range GFS is showing something interesting again, let’s see if it’s the beginning of a trend. I believe the 12Z ECMWF hinted at similar changes in the long term.

    Just when I was starting to get some hope from the dang GFS model. Good grief. Appreciate the info. Knowledge is power.

    The long range thru the 9th of January is for drier than normal–it backs up Marks outlook.

    I’m cautiously optimistic that the GFS is right and this pattern will start to change in 7 or 8 days. Yup, wish casting I know..but we must believe!!

    It never got above 34 today after a low of 27.5.

    No wind this year on the coast. I’m starting to feel cheated!
