ECMWF Monthly Maps

A day late, but here are the 4 weekly averaged 500mb height anomaly maps from the ECMWF ensembles:

Week4

The general theme of ridging beyond Labor Day continues, but this was the Sunday night run.  ECMWF runs since that time have backed off on the timing.  Take at look at the 12z ECMWF ensemble chart…in fact the coolest temps are just beyond Labor Day now:

There is some good news for Labor Day, the cold upper level trough appears to be arriving a bit later, so Saturday looks summery and Sunday could end up real warm/nice as well.  All is not lost yet!

    “Maybe a rumble of thunder/a flash of lightning”

    Just heard this statement from the the Great and Powerful Mark Nelsen! (His thoughts on the weather excitement possible on Thursday)

    Okay, so I cheated. I looked at the KATU weather blog. I feel so cheap. But check out those weather shoes! I thought they were the bee’s knees! Pretty cool, no?
