Few flurries possible again tonight, but icy roads the greater concern

SEATTLE -- Coming off the snowiest Christmas Eve/Day in Seattle history (at a meager 2.6 inches combined) some areas may get a second round of snow Tuesday night, but this time around, accumulations will be scant, if any. On the other hand, it will drop below freezing again, making for a potentially hazardous Wednesday morning commute.

The weather system coming in is splitting apart as it approaches the coast, losing much of what moisture it has available. Some forecast charts do show barely enough moisture for light accumulations of a half inch or less in Whatcom County and the San Juan Islands, and perhaps a similar light coating in the Cascade foothills.

Other areas, including the Puget Sound region, may see some flurries overnight with maybe an additional dusting at best, but no measurable accumulations expected.

On the other hand, temperatures will drop into the upper 20s to low 30s overnight, allowing what does fall and any lingering snow/melted snow to refreeze on area roads.

Thus at least plan a little extra time for you Wednesday morning commute, especially those in the outlying areas were lows in the 20s are more likely.

All freezing weather concerns end as we get into Thursday and a milder, wetter pattern takes hold. Temperatures will climb into the 40s on Thursday and Friday under steady moderate to heavy rains as two potent weather systems arrive back-to-back. However, the snow levels look to remain below pass level for potentially heavy snows in the passes both days -- so factor that in for any travel plans.
