Notes from Sunday's storm

Notes from Sunday's storm

A lot of weather to catch up on from this past weekend's storm, which had snow Sunday morning that had flakes described as just slightly smaller than a Buick, and then rocking winds.

Here are some tidbits from the mid-March storm:

Snow totals:

  • Brinnon: 6.5"
  • Shelton: 3.5"
  • Bremerton: 3.0"
  • Aberdeen: 3.0"
  • Potlatch: 2.5"
  • Bethel: 2.3"
  • Grand Mound: 2.3"
  • Federal Way: 1.5"
  • Lynnwood: 1.2"
  • S. Everett: 1.0"
  • Tumwater: 1.0"
  • Sea-Tac: 0.5"

Sea-Tac Now At #6 Snowiest Winter

Those who saw our weather blog entry from Thursday know that Seattle was at the 8th snowiest winter on record before today's event, just 0.1" behind 7th place and 0.5" behind 6th place.

Well, with Sunday's 1/2" of snow, the winter of 2008-2009 is now tied with the winter of 1953-54 for 6th snowiest winter on record at Sea-Tac Airport with 23.3". Normal is 11.8". We need 0.9" more inches to tie 5th place.

Mountains Hammered!

About 40" of snow fell at Crystal Mountain and Snoqualmie Pass over the weekend, with another 6-16" expected on top of that.

We'll have to see how this helps our mountains snowpack (sure won't hurt!), which was running about 70-90% of normal before Sunday. This week's snow is exactly what the doctor ordered, as late January and most of February was pretty paltry in the snow department.

Here is my blog entry on mountain snowpack totals as of March 15.

What was with the big snowflakes?

One of the most remarkable facets of this storm is the size of the snowflakes. Many e-mailers have commented on the large flakes. In fact, a reader from Shoreline described it as "it looked like someone was plucking chickens in the sky!"
It's a combination of heavy precipitation intensity, a slightly warmer than freezing temperature, and sticky snowflakes.
