WeatherWatcher: Snow Flurries followed by a warm up

Tuesday, December 26, 2017


Some snow flurries are expected overnight Tuesday into Wednesday morning. It may take until the afternoon hours for the snow flurries to change over to light rain. No accumulation is expected, and the main concern for Wednesday morning is patchy ice on the roadways for the morning commute.

Later Wednesday evening we are expecting to warm up into the 40's to finish out the week with a series of seasonal rain storms. There's even a possibility of a wind event later in the week as well. Forecasts have been very inconsistent last couple of weeks.

For those curious, Christmas Day was our first official White Christmas since 2008. There was 3.9 inches of snow on the ground this Christmas morning at the Shoreline weather station. The minimum to qualify is 1 inch.

History of White Christmas's in the Seattle area:

  • 2017: 3.9 inches on ground
  • 2008: 11-12 inches on ground (Shoreline)
  • 1990: ~8 inches on ground (Shoreline)
  • 1971: Sea-Tac had a trace, areas north of Seattle (Maybe Shoreline?) had up to 4-8 inches.
  • 1965: Sea-Tac received 1" on Christmas day, the official record for Sea-tac, tied with this year. 4" on ground, 8 inches on Christmas Eve that year. Unknown what it looked like in what is now Shoreline.

Sea-tac records only go back to 1944 and even with that, data for the Shoreline area is spotty at best. It's possible there's a few more in there that were not recorded.
