It’s snow time!

After sev­er­al weeks of most­ly dry/sometimes wet weath­er, Puget Sound and points to the north and the south are see­ing some sig­nif­i­cant snow… per­haps the only major snow event of win­ter 2012.

The Nation­al Weath­er Ser­vice fore­cast for today and the next few days calls for plen­ty of snow show­ers. Tem­per­a­tures will remain fair­ly cold until Wednes­day morn­ing, when things will begin to warm up, cre­at­ing what Uni­ver­si­ty of Wash­ing­ton mete­o­rol­o­gist Cliff Mass is call­ing “slush­maged­don.”

Here is the full NWS fore­cast for the next sev­en­ty-two hours:
