..Major Coastal Storm to Affect Southern New England Midday Wednesday into Thursday Morning. This storm will bring a widespread heavy snow to areas north and west of I-95 though some parts of Southeast Massachusetts may get accumulating snow as well as strong winds and minor coastal flooding though the winds and coastal flooding will not be as significant as the prior storm.

The southern edges of the Winter Storm Watches have been cancelled..
..A Flood Watch is now in effect from Wednesday Morning through Thursday Afternoon for all of Rhode Island and Southeast Massachusetts from Suffolk and Norfolk Counties southeastward except for Cape Cod and the Islands. Rainfall of 1-2″ with isolated higher amounts in a 6 hour period may cause urban and poor drainage flooding as well as renewed river and stream flooding given prior flooding from the previous storm..

Another major coastal storm is taking aim at Southern New England for Wednesday into Thursday. The headlines have the latest info. A few key items/factors for this coastal storm:
1.) This storm will not have winds as high or coastal flooding as severe as the prior coastal storm but there will be some strong to damaging winds at the coast line and minor coastal flooding that with weakened infrastructure may have more impact than normal given the prior storm. Wind and Coastal flood headlines are now posted for portions of Eastern New England.
2.) This storm will have very heavy snow accumulations for interior locations and it could be a heavy wet snow in at least a portion of the Winter Storm Warning area and possibly in the Winter Weather Advisory area, this could lead to pockets of tree and power line damage and power outages.
3.) The most problematic part of this winter storm forecast is the rain-snow line position and where the potential heavy wet snow lines up in the region and how widespread it is. Model solutions have been a bit warmer leading to adjustments in the Winter Storm Warning area, Winter Weather Advisories being issued in the southern portion of the Winter Storm Watch/Warning areas and a Flood Watch being posted in Southeast New England. This will bear close monitoring throughout the storm event.
SKYWARN Activation with Ops at NWS Taunton are likely 1 PM Wednesday Afternoon lasting through at least 1230 AM Thursday Morning. The overnight high tide cycle will likely be monitored via SKYWARN Self-Activation. This could be the last coordination message for this storm system unless a significant change to the situation occurs and time allows for an update.
