The reason for the enhanced snow prediction is that we're actually going to see two clipper systems zip through our area tomorrow. The first will generate snow beginning between 4 and 6 PM, and the second will generate snow from 9 to 3 AM.
This storm has the potential to sneak up on us, so we will raise the chance for a delay on the True North Confidence Meter to 10%. The leading candidates for calling in the delay are schools north of I-90 and Southern Berkshire, of course.
Stay alert and drive carefully tomorrow evening. Games/concerts/performances could get postponed if the snow starts earlier than 4 PM.
