..A High Wind Watch is now in effect for East Coastal Massachusetts, Cape Cod and the Islands, South Coastal Massachusetts and Rhode Island from Saturday Morning through Saturday Evening for sustained winds of 25-35 MPH with gusts to 60 MPH. Wind Advisories may be required for other parts of Eastern New England. These winds will likely cause isolated to scattered pockets of tree and wire damage and isolated power outages..
..SKYWARN Self-Activation is likely for Saturday with Ops at NWS Boston/Norton possible. Further details will be posted in future coordination messages..

A strong coastal storm/nor’easter will affect the region Saturday Morning through Saturday Evening. The headlines depict current thinking on storm impacts. Key factors on storm impact details include the following:

1.) There maybe some snow/sleet mix at the start in extreme northwest portions of the NWS Boston/Norton coverage area.
2.) The extent of strong winds in Eastern New England could be subject to some fluctuation. There are even stronger winds just offshore that if those winds could go over land could lead to slightly greater wind impacts.
3.) There is the possibility of an isolated severe thunderstorm along the coastal storm warm front in Southeast New England. While this is a low probability, given the trends over the past summer into fall on marginal severe weather potential becoming realized, it is noted as a possible threat. The isolated severe thunderstorm potential if it were to materialize would mean isolated pockets of more significant wind damage in any area impacted by the severe thunderstorm.
4.) Localized urban and poor drainage flooding is possible in areas that receive convective rainfall that enhances rain totals.

SKYWARN Self-Activation is likely for Saturday with Ops at NWS Boston/Norton possible. Further details will be posted in future coordination messages and the next coordination message will be posted by 8 PM EDT this evening.
