A tricky forecast is lined up for tomorrow as a Norlun trough develops over the area. The players remain largely the same as when I wrote yesterday’s post so please check that out for an explaination of the situation. These are tricky to forecast so anyone in SW ME, southern NH, and NE MA should be prepared for a coating-4″. Again, please check out last night’s post for details on the setup. I’ll repost last night’s snow map below as I see no reason to change it. The only thing different from last night’s post is that it appears unlikely any mesolow feature would form in time to provide meaningful impacts but if you want to learn how they work, that’s an interesting read.
