Pacific Northwest Weather Workshop

February 21, 2013

It’s the first weekend of March, a week from tomorrow;  the yearly Pacific Northwest Weather Workshop up in Seattle.  I’ve attended this event in the past few years and really enjoy it.  The presentations/papers are all focused on the Pacific Northwest.  Take a look at this year’s agenda here

You can also register at the same site.  Just $30 for two days; $15 if you are a student.  They always have really good cookies too, and it often includes a tour of the NWS Office up there at Sand Point.  I’ll be out of town so I can’t go this year…I’ll have to miss out.

ECMWF Weekly Maps

February 21, 2013

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:

Now the ECMWF weekly maps:
