WeatherWatcher: First day of Spring No, Winter?

The first day of spring has arrived, according to the calendar, but winter says "Wait! I'm not done yet!" We were greeted this morning with a Wind Advisory for gusts up to 50MPH and as it turns out this is probably our one of three significant storms this entire season (since last October).

Colder air behind this storm system from the Gulf of Alaska and British Columbia is being pulled down behind the low pressure center. The four letter S word is now in the forecast specifically for the Puget Sound Convergence zone. As I have mentioned in past stories, Shoreline and Lake Forest Park are typically right near the middle of the zone. Right now (as of 9pm Wednesday night) it is currently strongest over Everett but it is a very wide band, reaching Edmonds and the very far northern parts of Shoreline.

National Weather Service of Seattle expects areas hit hardest by the convergence zone could see up to 3 or more inches of the wet snow stuff on the ground by morning. They also are expecting several of these convergence bands to wobble through here through Friday afternoon. The air is cold enough that most of these showers could remain as snow during the night and day hours. No winter weather advisories have been issued yet so stay tuned to my twitter account or the National Weather Service as this may change soon.

There is light at the end of the tunnel, however. Saturday we will start to moderate out of the colder air as more Pacific air moves in. Also, as the sun is higher in the horizon now during the day, any snow accumulation is unlikely to survive any afternoon sun breaks.
