I don't think this GYX AFD is accounting for the tick back SE. They do acknowledge surprise that the models aren't showing more along the Maine coast.
In summary, confidence is increasing in the coastal
plain seeing accumulating snowfall, with less confidence inland.
Timing has also become clearer with snow likely not reaching
our area until the early hours of Monday morning and lasting
into early Tuesday. Amounts remain highly uncertain, but with
hi-res models now in the mix we should be able to lock onto a
more certain track over the next 24 hours.
