A snow day literally and figuratively falls from the sky, unbidden, and seems like a thing of wonder. -- Susan Orlean

Winter Weather Advisory for Monday Night/Tuesday

While it hasn't officially been announced yet, expect NOAA to announce our first Winter Weather Advisory for the season later tonight or tomorrow morning. WWAs usually mean less than 6 inches of snow.

Unfortunately, this storm will not be a big snow producer. What it will produce is a giant mess for those commuting to work on Tuesday morning. The snow--starting around midnight Monday--will come down for a few hours before changing over to sleet before the morning commute. The sleet will continue for an hour or two before we shift to all rain. Any accumulating snow--2 to 4 inches--will likely get washed out by the end of the day on Tuesday, which is bad news for skiers. Expect to see temps in the mid and upper 30s on Tuesday, explaining the changeover to rain.

Don't forget that earlier this fall we predicted that these types of storms would be the norm for this winter because of el nino. Without the cold air firmly in place, we're going to have to get used to snow/sleet/rain events. The silver lining is that these kinds of events are often better for school cancellations because of A) their unpredictability and B) the threat of ice. Road crews, Superintendents and bus companies all hate ice.

More to follow tomorrow, but look for the announcement of that Winter Weather Advisory.
