Gradient Keeper Posted January 12, 2020 Report Share Posted January 12, 2020 00Z EPS stopped running at day 14.75 for some reason... so here is the 9.75 - 14.75 day mean. Might not look great... but I will mention that both of those trough anomaly centers are slowly shifting west towards the end of the run which is actually a sign of retrogression and could lead to something later.Hell yeah! Big cold pool potential or even better! D****T, TIM! 2 Quote Link to comment Share on other sites More sharing options...

Perturbed Member Posted January 12, 2020 Report Share Posted January 12, 2020 Hell yeah! 1.33km Hi Res shows its cold enough to snow after 7 PM Monday! Yeah it looks pretty interesting. Here was the 12z for comparison. The low has shifted further north now to nail PDX instead. Hopefully the WRF is seeing something the others aren't since it is painting pretty cool temps fairly quickly. 1 Quote Link to comment Share on other sites More sharing options...

TT-SEA Posted January 12, 2020 Report Share Posted January 12, 2020 Generally add 3 degrees to account for ECMWF cool bias. Even if its too cold by 3 degrees... this looking like a very cold period for Bellingham. There is going to be a distinct line to the north where this becomes a true arctic event.

snow_wizard Posted January 12, 2020 Author Report Share Posted January 12, 2020 I'm going to go out on a limb and say the ECMWF is not handling the intrusion of Fraser River air into the Seattle very well at all. It continues to show Bellingham very cold on Monday evening and Seattle only near freezing with a perfect northerly surface pressure gradient and brisk north winds blowing straight down Puget Sound. Past experience tells me the difference between Bellingham and Seattle in a case like that will not be as great as the ECMWF shows. I could easily see low to mid 20s at SEA by 9pm Monday evening. We will need to watch how cold the Fraser outflow is very carefully. That is our best shot to still see some really impressive cold temps. 3 Quote Death To Warm Anomalies!

And everyone who posts their snow totals or pics will say I specifically said it wouldn't happen. But I never said that. In actuality a WRF / ECMWF blend would be awesome for many of us in the Seattle area. The WRF is obviously way too fast. The million dollar question is whether the ECMWF is too slow at advancing the zone. Quote Death To Warm Anomalies!

Experience tells me that the Arctic Front will be delayed a few hours, but most models end up getting the gradients set up right. However, with oceanic influence we may at least be closer to 32F than on the GFS.
