BOX and OKX have maps out but i noticed they only go through 7AM Friday.
BOX morning AFD, seems reasonable to me
The highlight of the extended forecast is the growing potential for
a Nor`Easter capable of producing widespread substantial snowfall for
southern New England. A broad upper-level trough is progged to dig
into the eastern US on Thursday supporting the development of a
surface low-pressure system off the mid-Atlantic coast. This coastal
low will track northeastward toward southern New England Thursday
night into Friday bringing the potential for significant snowfall.
There is still considerable uncertainty with respect to the track of
this storm, thus there is also uncertainty in which areas will see
snow (or potentially rain) and how much snow will accumulate. At
this point in time, it appears that a major blockbuster winter storm
will be unfavorable due to a lack of downstream blocking. Downstream
blocking would support a slower moving storm capable of producing
snowfall for a longer period of time resulting in higher
accumulations. Despite the lack of downstream blocking, the
potential for a respectable and impactful winter storm certainly
remains on the table.
At 96 hours out our best forecast tools lay within ensemble model
guidance. There is strong agreement among the global model ensembles
that the surface low will pass very close to the 70/40 bench mark.
In this scenario most of southern New England would see accumulating
snowfall. Ensemble mean 24 hour snowfall amounts from each of the
GFS/CMC/EC models fall in the 3-6" range in the Thursday night -
Friday night time period. The consensus for the "bulls eye" of
highest accumulations is over the I-95 corridor. The GFS ensemble
resolves a track a bit further north and west placing the heaviest
snowfall over western MA and southern NH. The relatively strong
agreement among global ensemble guidance right now suggests an
increasing likelihood for at least an advisory level snowfall event
for portions of southern New England and perhaps even a warning
level event. Again, considerable uncertainty remains so we`ll
continue to monitor the latest trends as the event draws nearer.
but what does the RPM say?
