It’s a little early to put exact numbers on a map for the storm that may have a major impact in Southern New England on Friday, but we can give a general idea of where the heaviest snow will most likely occur. The track of the storm will be critical because even though some chilly air will sneak into Southern New England ahead of the storm on Thursday, it may have a tough time sticking around if an intense storm system moves north. Typically, with very intense storms, some mild air gets wrapped into the coast and Cape Cod.

The storm is still a few days away, and a track any farther north than currently projected would definitely bring rain and mixed precipitation into play in the I-95 corridor including all but far NW RI and areas in MA outside of I-495. If the storm happens exactly as currently projected by most computer models, then the I-95 corridor would be among those receiving the most snow from the event. As a result, that area is shaded in pink for the potential of some rain or mixed precipitation, but still the chance of heavy snow.
As usual, it is the inland locations that have the best chance of seeing heavy snow during an intense Nor’easter. At this point, the computer models are predicting everything from a half a foot to two feet in the hardest hit areas. An accumulation map would be premature considering that the jet stream energy that is going to make up half of this storm has not yet reached the west coast. Based on that, Right Weather will be issuing a first look accumulation map for Pro members Wednesday morning.
The graphic below illustrates some of the impacts that are possible based on the current Right Weather forecast. As you can see, it would be a high impact storm for all types of travel, and school cancellations would be widespread. The high end snow totals reach 12″ or more, and the storm lasts for nearly 24 hours. Snow, mix, and rain are all in the equation for Southern New England, but, as explained earlier, it depends on where you live.
Is a jog to the east on the table as well? I feel like what I’ve read only mentions tracks further north and/or west.
Yes, a jog to the east is still on the table, and if you buy some late-afternoon model runs, then that is a possible trend. If there is not an eastward jog with the computer model runs tonight, then I think that a future jog to the right becomes an unlikely scenario.
