It should include the entire area. Makes no sense, it will be cold enough and if anything your area will have more precip than mine because of rain shadow.

As long as I'm south of the shadow, which looks possible.

NWS says you won’t be shadowed and there’s even a WWA for your area.

That seems really suspect, but you never know I guess.  This isn't really a Hood Canal situation.

They are sure diligent about dropping an advisory for every last little chance now.

It's called clown range for a reason.

Yeah it was predictable. They got caught asleep at the wheel for the big one and now issue warnings and advisories for even a trace. Rest of these "events" are almost certainly 0 snow in the city itself and an inch or two of wet snow in outlying areas or hills. Conversational snow.

Hopefully the NWS actually pays attention next time and also focuses on meteorology instead of pure statistical analysis of their 2 favorite ensemble models the SREF and NBM.

Already back into the 30s here after brief flurry.

Elevation really is important today for air temperature.  Bremerton airport is 39 and 440ft. Another observation near me is 38 and 500ft. I'm 34 degrees and 650ft.  Those places mentioned are just a few miles away from me.

We come from the land of the ice and snow.

The setup actually looks decent for Portland tonight. That low is to our west to allow some weak offshore flow to build this evening and it lifts a possible band of snow through the metro area late tonight. Lowest elevations could pick up some sticking snow. The rest of the week looks meh for the actual city.

Mesoscale models are growing happy about bringing in another round of snow this evening to the Sound. Offshore radar is juicy and the profile is convective... Could get real interesting. These are the kinds of snow events that when they work out, they can dump quite a bit of unexpected snow.

I’m back onboard!! 

It shows like 8 inches for you and only 2 inches for me!   

I was really expecting to get decently buried up here this week.   But the next system on Thursday and Friday appears to be too warm even for my area... so it all comes down to Tuesday.

Seems like focus will be right over the Seattle area too.
