On Sunday, an Arctic front was expected to move south down Puget Sound towards the Seattle area. This front moved very slowly, and before it could move south, a Convergence Zone developed between Everett and Mount Vernon, due to Southwesterly flow moving around the Olympic Mountains. This is the same SW flow that caused 35-45 mph wind gusts in our area. Back to the Convergence Zone...it sagged south to downtown Seattle and dumped up to 8 inches of snow between Mount Vernon and Seattle.
As you can see in the picture above...there was a lot of snow in the north Seattle area! This snow band "stopped" moving south in the Kent area. Some scattered snow showers moved through the South Sound on Monday morning, producing around a half inch of snow. Some of this snow made it down to Puyallup on Monday morning (picture below), but it melted through the day.
Monday night was the South Sound's best chance at snow, and most areas south of Seattle received 1-2 inches of snow. Snow lingered on the ground and some surfaces through the day Tuesday and through Wednesday night. On Wednesday night, the temperature rose up to 45 degrees. This temperature rise was associated with strong easterly winds out of the gaps in the Cascades. These winds gusted 25-45 mph in the South Hill, Puyallup, and Federal Way areas. Winds like this are extremely localized, due to the nature of gaps in the mountains.
We rounded out this week with some very localized snow, and my house in Federal Way received a dusting of snow this morning.
Some roads were icy/snowy this morning because of below freezing temperatures overnight.
This morning was the last morning with a chance of snow...we will go back in to a rainy and sometimes windy pattern for the next week.
