This major Nor’easter is off the coast a good bit and will not have that big an impact upon us. But for New England, it will be another big storm. Blizzard conditions are possible in eastern New England on Tuesday. This of course does not mean there isn’t a forecast challenge for us:
- When does northern trough energy engage, interact, and then capture storm off the coast?
- Engage: Pushes storm ENE off the coast.
- Interact: Storm pulled NE then NNE and precipitation begins to build westward from NW of storm.
- Capture: Storm moves NNE and precipitation expands dramatically well west of storm.
- See map for illustration
We are at the latitude near the interact and capture stage it appears. So when does the precipitation expand westward? I think it happens more to our north. But a slight shift in timing and we could see more snow.
Please take note: the worst-case scenario is about 4”. I doubt we will see that. More likely a coating to 1” in valleys and 1-3” on the hills by Tue evening.
After this storm, we stay chilly and winter-like for a few days, with some snow showers and even a snow squall on Wed before improving weather as we head into the weekend. A rain/snow situation appears possible the early part of next week. Ugh, winter is still not over.
