I am totally unimpressed with the precipitation coming in later this afternoon.
First, it will be cold enough for snow later this afternoon and early this evening. Forget the talk of freezing rain. The roads are cold. The atmosphere is too cold. No icing threat in the early to late evening.
What about precipitation? There is hardly any in the western interior. Here is the latest radar image (1213 PM) A few snow showers on the coast. There has been some on and off light snow at Quillayute and Hoquiam. Virtually nothing getting past the Olympics...these are very shallow showers.
The NOAA Rapid Refresh and HRRR models have pretty much nothing over us through commute time. Here is the accumulated snowfall through 4 AM from the Rapid Refresh. Nothing over Puget Sound.
Satellite imagery: completely unimpressive. A weak band to the north of us. No organized circulation approaching us over the Pacific.
Bottom line: homeward commute is no problem. At worst you might see a few snow flurries. With cold roads and no freezing rain, there won't be an ice problem. Watch the radar (here is a good place) if you want to follow the situation in real time.
Several models have the precipitation picking up a bit over night...but still light. Seattle and central Puget Sound and Kitsap will be heavily rain shadowed (snow shadowed). Some light snow from northern King County into Snohomish County and south of Tacoma is possible but light is the operative word...less than an inch. North Seattle might get a dusting. This is not a serious snow event if you believe the current models. There is a bit of hyping going around...but no names here.
Along the coast where there has been some occasional snow showers.
Are you in venture capital/private equity and have an office in the Bay Area, or knows someone who does?
If so, I have a question for you. Please send me an email (cmass at uw.edu) ....thanks, cliff
