*Changes ...*
- Latest forecast has trended warmer. - Lesser snowfall amounts towards the N&W. - Main strip of icing shifted N&W, but heaviest still remaining around 0.2 - 0.4" - Hartford County CT upgraded to a WINTER STORM WARNING
- Flood watch issued for Southeast New England. - Expectation of 1 to 2 inches with locally higher amounts. - A lot of residual water which will easily freeze as Arctic air pours in behind the storm.
- Coastal Flood headlines rescinded to just ADVISORY for the entire coastline. - Forecast minor coastal flooding along all coastlines, especially from Cape Ann northward.
*What / Where / When / Impacts ...*
- Heavy wet snow / sleet over N&W MA & CT with freezing rain / icing across interior areas of New England (roughly Hartford towards Northeast MA). - Greatest concern is the weight of the two on trees. - Add in the winds, there's an exacerbated threat for downed limbs and power outages. - Concern increases Sunday night with Arctic air building in, temperatures dropping down into the single digits with wind chills 15 to 25 degrees below zero.
- Strong winds. - Strong southerlies over Southeast New England Sunday, becoming blustery out of the NW going into Sunday night into Monday morning over all of Southern New England. - Again, concern with downed limbs weighted by ice and snow going through Monday morning over N&W portions of Southern New England.
- Flash Freeze. - Especially over Southeast New England which will see warmer temperatures and a soaking rain. - Residual water along roadways likely freezing if left untreated as Arctic air builds S across the region late Sunday into Sunday night. - Will make for significant impacts during the Monday AM commute, especially along the Boston - Providence corridor and points S&E.
- Marine. - Gale warnings on all waters. - Moderate to freezing spray developing Sunday night on through Monday, perhaps continuing into Tuesday morning.
