(CLICK ON ALL IMAGES FOR A LARGER VIEW) It will be nice to wake up Saturday to a classic New England Snow Sky and that distinctive smell only sensed by die hard New England Winter lovers (if you like snow!). It sure has been a while for many and this one should deliver. Snow looks to develop (lightly at first) Mid-morning to the west and south and make progress off to the north and east thereafter. Be advised but not surprised or discouraged if you start with a few raindrops.
Though I just do not see that happening for too long if at all with such cold air aloft projected. Snowfall will increase in intensity as the low pressure nears from our south and eventually looks to pass just southeast of The 40/70 benchmark and pass off to the northeast of Southern New England Sunday morning with some backlash snows and ocean enhanced snows falling along east coastal area’s.
This track is just a bit farther south than the last storm and makes all the difference in the world this time with ample cold air aloft to support a snowstorm for many folks. The area highlighted to received the most snow is Norfolk , Bristol and Plymouth Counties in eastern Massachusetts away from the immediate coastlines as well as central and northern Rhode Island and northwest Connecticut . Locations along the IMMEDIATE coast will be fighting marginal temperatures and dewpoints at the surface . The hope is the intensity will help drag down the colder air aloft (850mb temps) for a snow pack all the way to the Cape Cod Canal and perhaps a bit beyond.
<<<850 mb TEMPERATURES
The rest of Southern New England is in for a widespread 3-6” of snow with this one, and for that Winter Weather Advisories are in place for all, with Winter Storm Watches in place over the favored higher prone areas. The reason for the higher amounts east is the closer proximity to the storms center and temps and dewpoints optimal for a snow growth region. Also often times in these events a coastal front forms from Gloucester Ma-Plymouth-The Cape Cod Canal and snowfall just to the west of this front becomes enhanced as well as enhancement from the ocean from a LIGHT northeast wind fetch…Key is LIGHT, so it does not pull the milder air in from the Atlantic Ocean, so that is what is forecasted as the Max Zone. This is a fairly quick hitter and is out of here by dawn on Sunday, with perhaps a few ocean effect snow showers affected extreme eastern areas and Cape Cod on a north wind. The snow that falls appears to going nowhere fast as the very cold air rolls in behind from southeast Canada and will be going nowhere fast as well. In fact it could be the coldest first week of January for some dating back to 1996 ! It will go from 30’s to highs, to 20’s to teens for some through the first days of 2013. Far cry from non-winter last year eh!? The active pattern will take a breather with the renewed cold as it will be “Too cold to snow”. Thanks for reading and have a wonderful weekend Anthony
