In the last 24 hours, the models have made a sizable jump northward. Due to a fairly tight gradient on the northern edge of the storm over which accumulations drop off quickly, this raises accumulation potential considerably here in Keene.

A growing analog for this event is 12/13/07 during which we received 7.6" of snow. Not sure about that much yet, but if the trend continues, it is possible. At this point I am thinking around 5 inches of snow. My final forecast for tomorrows storm will be issued later tonight.

As for the rest of the region, expect a mostly snow event away from the coast. Highest totals will be across SW MA where up to 10 inches is possible. This storm will bring snow potential across most of the eastern third of the nation, and the most snow for many cities so far this year. In addition, strong CAD is possible despite overrunning warmth, which will make for possibly a major ice storm for parts of VA, MD, DE, NJ, and E PA. Count on significant delays tomorrow afternoon.

--- Snowday Outlook ---
Along with the changes in the accumulation forecast, the timing forecast has been altered a bit as well, with the southern storm picking up a little bit. Snow will likely reach Keene around 9am, and becoming heavy by noontime. I still dont think this will warrant a cancellation, but an early dismissal is becoming more likely.

Update on next weeks storm and the long term will be posted later tonight as well.
