From the National Weather Service:

[Sunday - Monday]

Winter Storm Watch Expanded. Storm / Gale Watches posted on the waters. Coastal Flooding potential continues to be evaluated.

Impacts ...

- Accumulating/plowable snow overspreading most of the area Sunday, possibly briefly lifting north of the region Sunday night before returning Monday morning as a burst of heavy snow across eastern MA, possibly into Rhode Island.

- Strong to damaging winds and associated power outages possible Cape Cod, Cape Ann and Nantucket Monday, possibly into all of eastern MA including the Greater Boston Area

- Coastal Flooding risk along the north side of Cape Cod (Sandwich to Eastham), Cape Ann and Nantucket during the Monday midday high tide cycle.

Uncertainty ...

- A rain-snow line will develop Sunday and begin tracking inland from the south coast into interior CT, RI and eastern MA. It remains uncertain how far inland this rain-snow line will track, which will greatly impact snowfall projections.

- Any rain early Monday morning will likely change back to snow, however there is some uncertainty on the exact timing of the changeover.

- Strength and proximity of the low pressure with reference to the New England coastline. A significant determining factor with respect to specific impacts across the region.

When will we know more ...

Given the storm has yet to form we will likely have greater insight on forecast details and timing this afternoon and especially by Sunday morning. Thus stay tuned to later forecasts and discussions on this evolving winter storm
