I think there is a good chance now that widespread snow will fall in the metro area tomorrow afternoon. If so, it could be a mess since it’ll be dry in the morning and most schools/businesses will be in session. We sure don’t need an Atlanta repeat in Portland tomorrow evening, so please think carefully before you head out in the morning.
The big story this evening is that models have shifted farther north with the precipitation and the evening ECMWF model (what I was really waiting for) still runs a ton of moisture with a surface low directly into northwest Oregon. That gives me enough confidence to say we’ll have our first widespread snow event in the metro area since December 2008. Here’s what I used at 10pm:
Here is our latest RPM model snow forecast:
I don’t have graphics showing how much the ECMWF model gives us snowfall-wise, but it appears to be enough for 3-5″ possibly.
