Some real nice bursts of snow showers this evening as the colder air has moved in. Speaking of cold air moving in…models just nailed it. I would have never thought I would see a gusty west to northwest wind and a temperature of 31 here at our station in Beaverton. Arctic air always comes in from the east (through the Gorge) here in Portland…well, apparently not always.
No change in thoughts about a Trace to 1″ for most areas. Of course more up in Kelso/Longview since you folks already had snow coming down all day long. Some snow now also in the Valley with a dusting in Keizer, Salem, Dallas, Monmouth etc… Once again, anyone can get some light accumulation. Even the north Coast is getting in on the snow action.
Edge of the dry arctic air (the arctic front) passed reaching Longview/Kelso about 1/2 hour ago. Dewpoint dropped from 27 to 21 in ten minutes as the wind went from gusty west to gusty north. That should reach a good chunk of the Metro area by 11pm to midnight. That’s when everything freezes solid. Watch out if you’re driving around after 11pm!
I know there are a lot of new people reading the blog tonight…since we’ve had 70,000 visits today. That’s far more than any other day in the 5 year history of the blog. Welcome to you folks! This is a place to discuss weather (really the only one in Portland), and notice the archives go all the way back to 2005. Feel free to check it out the “past issues” if you get snowbound by our mega 1″ snowstorm…
