How big does a mountain need to be for upsloping/downslopingto to happen? For example, the Olympics/Cascades are great examples. However, tiger Moutains peak is 3,000ft. Yet, there is no effect really (that I am aware of). Just bored and doing research when I should be working😂😂

Green and gold mountain on the kitsap peninsula are only 1700ft and they work to hold the coldest air between them and the Olympics.  I'm on the sw slope of those mountains and get much more rain than the bremerton airport weather station just a few miles east of me leading be to believe there is some upslope effect here from those small mountains.

We come from the land of the ice and snow.

Yeah March 2002 was pretty decent. Several really impressive cold shots with scattered valley floor accumulations. I think places up toward Bellingham didn’t really really well with that one. 2009

was good too. We had about 1/2” snow in Silverton, but places above 1000’ got 4-8”. Then some very cold dry days followed. 

Basically anywhere above 500' did well in March 2002. A couple days even had minor accumulations in Tacoma.

Little Mountain in Queen Elizabeth Park is Vancouver’s highest hill, which tops out at about 410 feet above sea level. I am east of it. If the winds are from due west, I get measurably less moisture (not a whole lot less, but still measurably less) than stations not in its rain shadow.

It's called clown range for a reason.

Models are showing a very sharp, thin, intense front will be headed our way and mainly effect the coastal regions of Washington and Oregon.  I don't recall seeing something so thin and uniform like this often with intense rain.  It will hit the coast Wednesday morning. Literally, it's looking like it's going to slap the coast in a downward angle.  How rude.

Wind and wind gusts will be pretty strong, ranging from 40 to possibly 60mph gusts.

Good analysis. We've had numerous sharp, dynamic fronts since the Fall. Not many have been all that splitty or weak.
