Earlier today we said we'd update if there were any new and exciting develops, and guess what? There are some new and exciting developments.
First, a Winter Weather Advisory will go into effect between 10 PM this evening until 7 PM tomorrow. We're very surprised by the 10 PM start because that typically means snow will start around 11 PM or midnight. Snow on the ground and still falling when the Superintendent wakes up is never ever a bad sign.
Second, the models are indicating the track of the storm to be farther west and closer to the coast. This means more liquid precipitation for our area, which of course means more snow.
Third, it's going to be cold tonight--mid-teens--which means the snow to liquid ratio will be above the typical 10 inch-to-1 inch ratio. A quarter inch of liquid would typically yield 2-3 inches of snow, but with this cold air hanging about a quarter inch could get us to 4-5 inches.

So, given those changes, we're going to bump up the chance for a full snow day to 50%. This means you have a 50% chance of a snow day due to the improved conditions. This also means that we think 50% of schools in the county will have a snow day.
Tomorrow morning we'll post a running list of school cancellations should Superintendents decide to call them in.
Do your favorite snow dance tonight before going to bed to improve our chances!
