Winter Weather Advisory Upgrade

The GSD Staff just got a little more excited with the most recent update from the National Weather Service. Two important developments: the Winter Weather Advisory has been expanded to Southern County, and the North County Advisory has increased projected snow totals from 2-4 inches to 3-6 inches with additional expectations for ice.

The South County Advisory is calling for 1-2 inches but with mixed precipitation. As they say, ice is nice.

The bump in the North County snowcast suggests there will be enough sustained frozen precipitation during the day on Friday to make for hazardous driving conditions for the ride in and the ride home.

Here are some of the latest maps for your perusal:





We certainly like this way the storm is trending. We'll bump up the True North Confidence Meter to 50% for North County (NC) and 30% for South County (SC). We also think delays are possible tomorrow in South County for those schools that have school. But because precipitation is expected throughout the day on Friday, delays in general will be limited.

This is probably a "snow-day-or-bust" scenario for Mount Greylock, Adams-Cheshire, North Adams, BArT, McCann and Central Berkshire. The others will be touch and go and will have to get very lucky. But it's possible.
