WEST SEATTLE WEATHER: Snow’s overnight no-show; morning showers

6:37 AM: Good news if you were worried about getting around today, bad news if you were hoping for a chance to throw a few snowballs: No snow so far, just rain. The National Weather Service canceled its alert a few hours ago and explained in the “forecast discussion”:

What needed to happen to get snow in the lowlands early this morning was a combination of the winds becoming northerly cooling the air mass down before the moisture from the frontal system moved out of the area. What happened was the surface low associated with the system instead of ending up near the mouth of the Columbia river is now just west of Grays Harbor. This difference in the low position has kept the winds from Everett southward easterly overnight instead of the winds becoming northerly. In these marginal low snow level scenarios for the Puget Sound region the low level easterlies are a killer. The little bit of downslope warming from the easterlies keeps the temperatures warm enough to keep the precipitation type as rain and that is what happened overnight.

The forecast still suggests the possibility of snow showers.

7:24 AM: One of those showers has arrived.

5:39 PM: We’ll have an update later, but in the short run – the NWS now warns things could be icy Monday morning.

      It’s heavier now than it’s been all day. Hadn’t been sticking but I can’t imagine that won’t change IF this keeps up.
