It’s Thursday afternoon, so a fresh run of the ECMWF out to 30 days. Here are the week-by-week maps.
By the way, models have warmed even further with the Saturday and Tuesday troughs, so we have eliminated any “snow in the hills” wording on our 7 Day forecast. There could be sticking snow briefly Saturday morning as low as 1,000′ in the Coast Range and west slopes of the Cascades, but more likely up around 1,500′. The 18z GFS doesn’t even have it that cold for Tuesday now and the ECMWF is around -5 to -6 at that time at 850mb.
Here is the 12z ECMWF ensemble chart, followed by the 18z GFS chart:
