ECMWF Weekly Maps

The usual, 4 maps showing upper-level heights and height anomaly for each of the next 4 weeks.  It’s from the ensemble runs of last night’s ECMWF.  Interesting that the western ridge seems to disappear around 11-15 days from now.  Not sure exactly what happens after that though.  February MIGHT start a bit wetter…maybe.

    Here’s an idea to stew on: Suppose we don’t get much rain between now and Valentine’s Day. Then we get another strong upper-level ridge the 2nd half of February. Would the much drier than average water table and soil make it easier to get sunshine and a good false spring, than it would if we got a late February ridge after a “normal” winter?

    What comes to mind of course was late February 2005 which came on the heels of a dry winter. Spots in the central Willamette Valley got up to 65-70 degrees despite overnight lows in the upper 20s!

    00z EURO full run
    The demise of the unbreakable western ridge? Obvious retrogression of the PV as the flow bends around quite sharply in British Columbia and Alberta. The cold air gets oh so close, but as the “head” of the block is pinched off southwesterly flow tries to move into the picture. This shoves the cold air back up into the Canadian prairies. At least a pattern change is showing up before day 10 now.

      I’m liking it. Gfs and now euro. Ready for this change and by the looks of that 965 low coming in from west looks a little chilly itself as per 850mb temps.

      12z it is gone and the ridge continues

    In February sounds about right. I was out of town for the cold in December and I’ll be gone again for half of February. If my leaving the area is what brings the interesting weather I guess I will do what I can for the cause.
