who cares about the NAM at this range, or the NOGAPs?

NAM is in the banter thread... and NOGAPS has been consistent like the EURO past 6b runs and looks almost exactly like it so it shows some consensus... unless you want the wild swings of the GFS... and the GGEM/UK swinging wildly as well... those two models have been locked in

Oh I know - but you have done a damn good job posting it In. Every. Subforum.

Won't defend NAM at 84, but I thought I read in other threads from maybe some of the tropical red taggers that the NOGAPS was actually a good model for hurricanes and these kind of systems. Dunno if that is right or not, but they were not as dismissive of it in this scenario as it is perhaps okay to be for a pure winter set-up...

I think the gfs is likely wrong. I keep going back to what agnes did with an upper low. I don't know whether the new euro and gfdl which take the storm and track it just north of us are right. They seem to be extreme solution but when almost every ensemble member from all the different centers are saying a hit somewhere from the mid atlantic to new england is going to get hit. It's pretty wise to start talking about amjor impacts as this storm is likely to have them even if the pressures are forecast quite a bit too low.

This is all I need.

I'm in now and starting up The Bus ™. Hi Ian!

Cut and paste discussions?

Friday through Wednesday: The Inland Northwest remains in an

active and potentially rather soggy pattern as a train of systems

come in from the Pacific. Temperatures and snow levels will begin

to rise by late this weekend. The first shortwave system arrives

Friday, with a warm front and occlusion pushing across the

Cascades and stretching through the southern CWA. Strengthening

isentropic ascent meets with deepening moisture in the 290-300K

layer from Chelan county through the Palouse, leading to

increasing PRECIPITATION through the morning to early afternoon.

This expands across the remainder of the CWA through the

afternoon. Throughout the day, however, the best lift and moisture

and highest PRECIPITATION chances and amounts are directed across

the southwest half of the CWA. Much lighter PRECIPITATION amounts

are projected across the Northeast Mountains through northern

Panhandle. By Friday night the weakening shortwave and slackening

isentropic lifts pushes the focus for PRECIPITATION toward the

mountain and southeast zones, while it wanes in the lee of the

Cascades and deeper Basin. Based on 850mb temperatures between -1

to -3 C and wet-bulb zero heights, snow levels will be near valley

floors during morning except across the Basin/Moses Lake area

where they will be between 2500-3500 feet. By afternoon the mean

snow levels across the CWA rises to between 3000-4000 feet.

Media Hype Watch:

Effective 5pm Tonight?

Most likely - Ive heard rumbles of it on all news casts I have listened to since last night. Was even mentioned on the nightly news.

But its been only mentions, nothing serious. Id imagine if the Euro holds serve today, and if the GFS starts to show the same... the news will be all over it tonight.
