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

Storm Fannie Update

An impressive wall of moisture is pounding the capital region. Unfortunately, that capital region is about 400 miles to our south. The low pressure system is more or less stalled out on the mid-Atlantic coast because the big, strong high pressure system situated over northern New England is locking it in place.

Optimism from Channel 10.
The low pressure system rotates counterclockwise and the high pressure system rotates clockwise. Where these two systems meet--practically right over us--we're seeing the outcome: very light snow showers and snow drizzle from our east. The winds will also kick up from the east as this light moisture pulls over us. A few snow bursts could be more moderate this evening and cover the roads.

It's unlikely the big wall of moisture to our south will have that much of an impact on the Berkshires as we will be on the fringe of Fannie's ferocity.

Even more optimism from Accuweather.
Tonight, we should see 1 or 2" of slushy snow. Tomorrow the precipitation will stop for a while mid-day, then the storm gets going again in the evening. The storm is moving slower than we originally thought, so we now have a better chance of a delay for Friday. We could see 3-4" in the overnight hours on Thursday, creating slick conditions for AM commute. We've flip-flopped our delay predictions for Thursday and Friday, but neither inspire much confidence for a shorter school day.

So much depends on the lifting of the high pressure, which will allow the low pressure to move in a northwest direction. It's a powerful storm, and we'll see that power when the winds kick up later and tomorrow.
