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

Upslope Snow

Good morning! Those of you looking for the list of cancellations and delays, you can go here. Sadly, we didn't see too many upgrades over night. There still could be a few more, but most likely this list is final. Schools north of Pittsfield were the big winners with this storm.

As for today, Berkshire County will see what is called upslope snow. What lake effect snow is to Buffalo, New York, upslope snow is to Berkshire County. After a big storm exits to our east, the wrap around energy creates a snow pipeline from Canada down through the Green Mountains and into the Berkshires (see below). Sometimes, we get trapped in this upslope snow for hours, which can lead to several more inches of accumulation in the dying hours of a storm.

Today, we'll see another 1-3 inches from upslope snow, especially in northern Berkshire County.

The other big issue, which you've probably already noticed, is the wind. We do have a Wind Advisory for the County, which means sustained winds in the 20 and 30 mph range with gusts up to 50 mph possible. Roads next to open fields and spaces could be particular treacherous during the day because of the blowing snow.

Everything will start to wind down late in the afternoon and in the early evening. The snow will be intermittent throughout the day before coming to an end this afternoon. Winds will finally die down around nightfall.

Next up for Berkshire County is a minor storm for Wednesday morning. Originally, the thought was we might see a third nor'easter, but the two energy systems will not phase and create a large coastal storm. Instead, we'll see about 2-3 inches during the morning commute and morning hours. Yes, delays are indeed possible.
