One or possibly 2 organized bands of precip swing through tonight. I bet some places near warning criteria of 5+ cm by morning

I was looking at the ones due west of Vancouver..the twins. Hopefully they spit out some heavy bands tonight. I hope 5-10cms, especially if a band stays stationary over an area. This will be convective snow bands =eeeeeeuge flakes and (hopefully) intense bands of precip
Could be some big accumulations
I love troffs!!

Can anyone help identify the area this pic is from. I was searching webcams and found this one but it says it may be from Coquitlam or Abbotsford. Both could be wrong, but someone here might recognize the area.

.SHORT TERM /TONIGHT THROUGH THURSDAY/...An upper level trough
will maintain a cool air mass overnight with low snow levels.
Steady, heavy snow will ease in the Cascades and the Winter Storm
Warning will expire at 4pm this afternoon as planned. Down in the
lowlands, the snow levels will drop to around 500-1000ft overnight
and hover around there through Tuesday morning. Most areas will
remain above freezing but cannot completely rule out a rain/snow
mix through the period. Areas that are likely to see an inch or
more of snow will be Hood Canal (especially along the west of 101
near the Olympics) and the East Puget Sound Lowlands for areas
like North Bend (where temps will be around 30). Therefore, will
issue a Winter Weather Advisory for these two lowland zones. In
addition, strong high pressure will build over interior B.C. with
gusty Fraser River outflow winds developing late tonight and into
Tuesday. This will bring strong N/NE winds to mainly western
Whatcom county. Winds may persist further into Tuesday night and
even Wednesday.

We'll see a brief break in the action on Wednesday, then another
threat of accumulating lowland snow Wednesday night into
Thursday. This is a classic overrunning setup with cool N/NE flow
(Fraser Outflow) and low snow levels while a warm front spreads
moisture up from the south. Timing is crucial - how far south do
the north winds reach and when does the warmer air mass move
inland? At this point, it looks like areas from Seattle/Tacoma
northward will see some accumulating snow with highest amounts
over Skagit and western Whatcom. Seattle/Tacoma will see a
changeover to rain early Thursday morning as the warmer air mass
pushes inland (snow levels rising to 6000 ft). Everett-area is
more like mid morning then afternoon for Skagit and Whatcom (thus
higher snow amounts). All areas should be rain by Thursday night
with temperatures mostly in the 40s. This pattern also brings more
heavy snow to the Cascades with freezing rain possible (east
winds keeping pass temps below freezing). Meanwhile, heavy rain is
possible for SW WA which brings the potential for river flooding
on the Chehalis, Skookumchuck and Newaukum Rivers (the Skokomish
too). 33

A brief warm up Thursday late with a cold trough swinging through Friday and Saturday before some form of ridging moves in

Basically impossible to pinpoint, but the HRRR swings multiple bands of mixed precip/wet snow through the mainland overnight.
