Latest forecast changes ...
* A Winter Storm Watch has been issued for Cape Cod and Martha's Vineyard
* A High Wind Watch has been issued for Cape Cod Martha's Vineyard and Nantucket
* A Storm Watch has been issued for the waters around Cape Cod and the Islands
* A Gale Watch has been issued for all remaining waters
What we know ...
Accumulating snow is likely across RI and Southeast MA Saturday night into Sunday night. Heaviest amounts are expected on Cape Cod and Martha's Vineyard. In addition, northeast winds will become strong late Sunday with gusts up to 60 mph possible across Cape Cod and Nantucket.
What we don't know ...
Storm track uncertainty continues. It remains possible that a shift in the storm track could bring more snow and higher winds farther north and west into Eastern MA. A shift in the track closer to the coast could bring a mix or change to rain to more of the Cape and Islands, affecting snow amounts.
In addition, snow intensity will be critical during the daylight hours of Sunday given temperatures will be near freezing. If snow intensity remains light, then accumulations may be confined to non-paved surfaces only, with roads remaining wet or slushy. However, if snowfall rates are moderate to perhaps heavy for a time, then roads will likely become and remain snow covered, resulting in a greater impact on travel.
When will we know more ...
The forecast should become more certain with time, however it may not be until Saturday that specific details are well known. Thus stay tuned to later forecasts and discussions for the latest trends on this developing weather system. Headlines will be adjusted to reflect forecast thinking.
