An arctic cold front continues to move east this morning pulling very cold air in behind it. In fact, temperatures will fall into the single digits by this afternoon with possible wind chills as cold as -15°. A few flurries and even light snow showers will persist through the morning before partial clearing occurs later this evening. The little clearing we'll experience tonight will allow temperatures to drop quickly before holding steady as clouds move back in.
The storm that we're watching for Friday is just now entering into the Pacific Northwest. As it stands right now (keep in mind some of this will change) the snow could start as early as 6am or 7am and intensify throughout the morning and into the afternoon. It looks like the heaviest of the snow may come very late in the morning and through the afternoon; this is when the best forcing in the atmosphere will arrive. Temperatures will be in the teens during this event which will cause the snow to be fluffy. Snow to liquid ratios could be as high as 15 or 18:1.
With total precipitation amounts nearing 0.40", snow totals could be between 6" or 8". One important thing to keep in mind with this storm is that it is now just entering into the U.S. so we'll be able to get a better data sampling as it continues to push onshore. We'll continue to provide updates here on the blog, as well as facebook and twitter.
