J.Spin has to be getting relatively crushed. I usually take the 30dbz yellow pixels, assume downstream drift, and then know that those echos are usually 1"/hr rates at least. That was a pretty good pulse for the Spine in J.Spin's area.
Looks like I-89 and RT 2 are still just wet in Bolton, but looks like it's snowing decently in the low elevations (300ft) along the Spine. Once those roads give in to the cold temperatures tonight and salt doesn't work as well, it'll be quite slick out there on the Interstate through the Spine.
