in a couple of runs with the Euro yesterday, frequently on the GFS, and here on this RDPS, there is a consistent strip of higher qpf that keeps showing up for western merrimack county and over to Lewiston. I noticed that in the days leading up to Dec 17 2020, a higher strip in similar areas up my way. I take that to mean that we have a chance to maximize accumulation up here. I'm sure Brian and Jeff will have a thought about this.
Often we see just the opposite up here in coastal storms where the big bands are off to the east and west of the Merr. River Valley, and we know that is a sign of a local minimum probably related to downsloping in the valley. Perhaps the signal on the current storm reflects long easterly flow running into the hill immediately west of the Merrimack river?
