luvssnow_spokane Posted December 12, 2016 Report Share Posted December 12, 2016 Well, in the end Portland has a better chance at getting snow than the puget sound if you take an average of most of the runs to far.

Prairiedog Posted December 12, 2016 Report Share Posted December 12, 2016 I just saw his actual new post. I'm not surprised the WRF-GFS currently shows what it does. I hope he doesn't make a mistake of relying on it. It seems like it can't see the northern moisture. Take for instance the first snowstorm of Feb 2014. This is what the WRF-GFS showed a day out and what actually happened. I think Mark is perfectly capable of what to rely on and not to. Perhaps the very best Met we've had for this area. I'd follow his thoughts long before I'd follow hype. Quote Link to comment Share on other sites More sharing options...

bainbridgekid Posted December 12, 2016 Report Share Posted December 12, 2016 Like last night, even Seattle is flirting with disaster on the NAM. The drama continues... https://m.youtube.com/watch?v=Oci1CuCht7EIt really feels like whichever model is the furthest North usually ends up being more right with these strengthening storms moving up the Coast. Even when it is the NAM. I feel pretty good about this storm for Puget Sound. I'd say I'm at least as concerned about it going too far North than about it going so far South to leave us totally dry. I also have some concerns on temperatures for near sea level even with the right track, but those details won't be ironed out till we see how much cold/dry air we have in place over the next 24-36 hours.

It's not universal and there is plenty of historical precedent for the more southerly solutions but it's just a matter of who will win out. The NAM has been pretty solid of late, and once again it was the first to start entertaining a stronger, warmer and hence more northerly track. At this point I wouldn't mind seeing Seattle take the brunt of it. Jim is going to be insufferable if we get a few inches down here and Seattle gets very little.

bainbridgekid Posted December 12, 2016 Report Share Posted December 12, 2016 The 4k NAM shows rain though for most of the sound lowlands. I definitely have some slight concerns about temperature even directly North of the low. The WRF from last night for example gave Seattle almost all rain despite the Operational giving them nearly a foot of snow. It will really depend on how well the cold dry air becomes entrenched over the next 24-36 hours. Like Dewey said . . . the drama continues.
