Cloud Posted February 23, 2019 Report Share Posted February 23, 2019 easy, modeled snowfall doesn’t count unless it actually fallsReallt depends on the ratio. This stuff appears to be wet, so maybe a 5:1 ratio which can add up fast. Quote Link to comment Share on other sites More sharing options...

Perturbed Member Posted February 23, 2019 Report Share Posted February 23, 2019 We probably need until tomorrow night before we can call this thing a lock but looking pretty good now. The trend is undeniably south. Every single model has trended south except for the GEM which was already fairly far south. 2 Quote Link to comment Share on other sites More sharing options...
Requiem Posted February 23, 2019 Report Share Posted February 23, 2019 I still have a feeling things will track further north...more often than not that ends up being the final outcome.Again, I think this may be a 2/6/14 scenario. High totals, but a low landfall closer to Tillamook.

Frontal Snowsquall Posted February 23, 2019 Report Share Posted February 23, 2019 My current thinking. EURO will creep south little by little right up to the event while the GFS/FV3/UKMET will creep north. They'll meet somewhere in the middle with a slight lean northwards as precipitation always seems to make up further North. PDX Metro is looking good at the momemt.

Perturbed Member Posted February 23, 2019 Report Share Posted February 23, 2019 I still think this has huge bust potential for PDX. Still 48 hours away with marginal temps. As long as the low is south of us, the temps won't be an issue. The gorge and east winds will take care of that. Every single model agrees on that. Cold air will reinforce in the Columbia basin even before the arrival of the low. The only tricky thing is making sure the low doesn't go north of us.

Cloud Posted February 23, 2019 Report Share Posted February 23, 2019 the gorge will be a big factor. Low is approaching from the sw instead of nwRelying on the gorge is gonna be dangerous this late in the season. The bust potential is there which is why I think a lot of the models are having problems figuring this system out. We’ve had model runs that include rain, ZR, and snow for PDX.

Yeah, not to mention the low that tracks through OR during the day Sunday will add more fresh snow to an already solid snowpack in the Columbia River Basin ahead of the system coming from the SW. Add healthy precipitation rates and PDX will be fine. 2 Quote Link to comment Share on other sites More sharing options...

Phil says that is impossible and only happens in our "magical" climate where an entire snowstorm can occur when its above freezing and then snow can miraculously stick around even when its 40 degrees in a dry air mass. I am not sure if its magic... but it happens all the time here.
