It snowed 2" here on the 9th. Biggest snow event of that winter for me. Wouldn't have been much colder in January/February, though. Just a very chilly onshore flow pattern. 4 Quote Link to comment Share on other sites More sharing options...

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 I’m pretty sure some places in city limits of Seattle average a few inches less of rain yearly due to shadowing from Queen Anne and Capitol Hill. Downtown even is shadowed from the West Seattle hill. Not enough shadowing obviously to dry them out when storms come through but just enough for the annual precip totals to be a bit less than other places. Don’t know if downsloping and shadowing are related but this just shows it doesn’t take that high of a hill to cause effects on the weather. 6 1 Quote 2023 - 2024 Cold Season Stats Total Snowfall - 0.75” Max Snow Depth - 0.5” Coldest High Temp - 21 (Jan 13) Coldest Low Temp - 9 (Jan 13) Number of Freezes - 48 Sub-40 highs - 12 Highs 32 or lower - 3 Link to comment Share on other sites More sharing options...

But Cedar Lake station at 1,500 feet had about 6 inches of snow in that period. That one cut off and thus was a little more impressive the further south you went. I think snow levels got below 1000' in the Bay Area with that and parts of SF had some snow mixing in with the showers. 1 Quote Link to comment Share on other sites More sharing options...

snow_wizard Posted January 18, 2023 Report Share Posted January 18, 2023 The cold is making a bit of a comeback east of the Cascades with some stations not getting above freezing today. Douglas is one of the cold spots again with a 32/22. As proof that elevations doesn't totally explain how cold that place is they are at 2,600 while Blewett Pass at 4000 feet got up to 37. Maybe it's a combination of being a good spot for inversions in combination with elevation. 2 1 Quote Death To Warm Anomalies!

But most of us, and I've been guilty, look at the operationals for the long range. Especially when it shows something good. 1 Quote Link to comment Share on other sites More sharing options...

The night of 3/8 was pretty fun with a ton of windswept snow showers in the strong westerly advection. Pretty rare. 1 Quote My preferences can beat up your preferences’ dad.

Maybe it's a combination of being a good spot for inversions in combination with elevation. Inversion makes sense. There's often a freezing fog that clings to the Waterville Plateau in winter while areas below and above are sunny. It's a broadly bowl-shaped plateau so air probably settles in the middle. 1 Quote Useful weather links Link to comment Share on other sites More sharing options...
SilverFallsAndrew Posted January 18, 2023 Report Share Posted January 18, 2023 My current location probably had 8-12” with the march 2006 event. The sticking snow was pretty spotty at the lowest levels. I remember the Tanesbourne area had 1-2”, but over in Aloha they had nothing.
