A strong coastal storm remains on track to impact Southern New England. The updated headlines cover the storm potential. Factors that will be defined as the storm unfolds 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. High Wind Warnings have been issued and expanded to cover much of East and South Coastal New England.
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 and there is even the possibility of an isolated tornado or waterspout.
4.) Localized urban and poor drainage flooding is possible in areas that receive convective rainfall that enhances rain totals. A Flash Flood Watch has now been posted in Southeast New England where this potential is greatest.
SKYWARN Activation with Ops at NWS Boston/Norton will commence by 730 AM Saturday Morning lasting through Saturday Night for the coastal storm. This will be the last coordination message on this system as we shift into operations mode.
