TT-SEA Posted January 3, 2016 Report Share Posted January 3, 2016 The WRF shows pretty good precip amounts up here early Monday, but gives no indication of any lowland snow. With easterly winds freezing rain could be a strong possibility for areas of the East Puget Sound lowlands. I don't mind it so much with rainfall amounts less than a third of an inch or so. The WRF also indicate many places remaining below 40 for highs on Monday. I have already accepted the fact that after 2 weeks of dealing with the kids at home... the schools will be closed on Monday due to freezing rain or snow. Ironically, they will be home on the day that all the snow finally melts here.

BLI snowman Posted January 3, 2016 Report Share Posted January 3, 2016 I heard recently and repeatedly around here that Mark is all washed up. Pretty suspect forecast. Hope he's right. It's a tad on the optimist side (I'd be surprised if anyone sees 3"), but in general I think he's right to catch onto the late cooling trend with the operational models. There's no question the operational GFS supports an inch or two across the entire area. Probably a decent chance that the trend is with good reason.

Heaviest precip in Portland is during the evening tomorrow on the ECMWF... and in Seattle all day on Monday. Precip band completely stalls over Seattle on Monday and the flow is still offshore.

Perturbed Member Posted January 3, 2016 Report Share Posted January 3, 2016 The PDX NWS needs to adjust their forecast for Portland metro pretty quickly, they are underplaying this quite a bit. Snow or not, there will be .2 to .4+ in QPF of frozen stuff coming in tomorrow in some form. They still seem to be under the impression that we will see some ZR drizzle around here. Mark Nelsen quite confident that PDX will be all snow at least for the first half of the precip: "During at least the first half of the event the atmosphere overhead should be cold enough to support snow all the way down. For sure that’s the case in the metro area; I’m less confident on pure snow from Salem south to Eugene (thinner cold layer above). " Seems reasonable to me. He thinks PDX might be all snow as the models might be pushing the cold out too fast even aloft: "the rest of us in the metro area would stay in snow longer…possibly through the entire event. Remember during the last east wind event in mid December that models eroded the cool air higher up too quickly…the precipitation stayed as snow longer than we expected. That might be the case tomorrow." Quote Link to comment Share on other sites More sharing options...

All of the models presently show enough QPF to create issues tomorrow. Virga looks to be a pretty fleeting issue before the lower levels moisten up adequately. I think they're holding onto their bearishness as long as they possibly can, but a Winter Weather Advisory is definitely warranted. Quote Link to comment Share on other sites More sharing options...

It seems like the NWS consistently does a pretty poor job predicting wintery events for Portland. This IS a very difficult area to predict snow, but they have had a lot of big busts on both sides of the coin in the last decade. Quote Link to comment Share on other sites More sharing options...

And this is an impressive cold pool set-up. Also we have the models trending wetter and slower which might also be related to the interaction with the cold air mass in place.

SilverFallsAndrew Posted January 3, 2016 Report Share Posted January 3, 2016 I always say a general rule of thumb for PDX in a "cold pool" east wind type situation is that you want temps 28 or lower at The Dalles and 24 or lower at Pendleton.

epiceast Posted January 3, 2016 Report Share Posted January 3, 2016 I think we had an event similar to this that dropped about a foot over Snoqualmie pass 3 years ago. The lowlands were just a tad too warm snow levels were somewhere between 500' and 1000'. The models didn't catch on to the massive precipitation until 24 hours before the event. I don't think it was caused by a ULL coming from great basin and tracking NNW, it was more of a typical ninoish ULL that got stuck in California and then somehow went north.

Gradient Keeper Posted January 3, 2016 Report Share Posted January 3, 2016 I was right. 6z NAM has more QPF/Moisture .40" to .75" and 2-4" snow for PDX. As much as the past 3 runs have moistened that could continue... Snow storm anyone? Quote Link to comment Share on other sites More sharing options...
