I’m going to lower my snow total forecast for overnight into Tuesday morning. My reasons are as follows:

1- computer models today have trended a little further south
2- its so cold and dry out there it will take the snow a little longer to reach the ground (and not evaporate)
3- In looking at observations and radar this afternoon, most of the snow that is moving this way looks to be moving more to the east than north east. I’m starting to think this may be the southward trend
4- The NWS only has a winter weather advisory for Hunterdon county and nothing further north and west.

So I’m thinking we are more likely to see 1-3”

What can go wrong? The storm could track further north and put us in heavier snow. And since it is so cold, the snow ratio will be higher. Normally when it’s close to freezing, 0.10” of liquid will equal 1” of snow. But when its colder, this goes up. In fact it goes up more as it gets colder. Right now we could be in the 20:1 ratio area meaning that if only .1” of precip falls, that will give us 2” of snow.

If I see this change drastically later on this evening I’ll update.
