UPDATE TUES. 1/11/11 1pm: The National Weather Service is sticking to their prediction for today’s impending snowstorm, saying that 1 to 4-inches of snow is probable, starting in the late afternoon, then turning to rain after midnight.

“One to three inches of snow likely. Locally heavier accumulations are possible near the Cascade foothills … snow will begin late this afternoon and change to rain after midnight,” reads the statement.

University of Washington Meteorologist Cliff Mass thinks the snow will arrive a bit later:

“The latest high-resolution run shows light snow hitting Seattle between 5 and 6 PM and perhaps could hold out until 10 PM before it turns to rain. Could be some freezing rain at the tail end.”

Here’s the most-recent Weather Service statement in its entirety:

Statement as of 10:59 AM PST on January 11, 2011
