There has been 1-3 inches of additional snow this afternoon, with many large flakes. The origin of this afternoon's snow is a band rotating around an offshore low (see sat pic--you can see the clouds swirling around the low). As clear from the radar..this band is associated with light to moderate precipitation. The band is over western Washington right now and will be moving through by mid-evening. After that there will be a break, followed by additional snowshower bands overnight that will be swing around the low. Total new accumulation today could reach 4-6 inches in some locations.
Not everyone has been getting snow..there has been rain on the coast. Portland has had snow, but rain is falling to the south in Eugene.
Monday will be cool
(highs in lower to mid 30s), but generally dry. We should stay with below normal temperatures for several more days. As a result, there is a good chance this will be a white Christmas (a white Chanukah is a sure thing....since it starts tonight!). By the way, a white Christmas only occurs 7% of the time....and did I mention there is the potential for more snow this week? In particular, there may be serious accumulations on Wednesday.
