In lower levels, models are starting to converge as NAM/ECMWF have
trended colder, albeit not quite as cold as GFS. Forecast soundings
show very favorable signal for a rapid transition from rain to sleet
(perhaps a brief period of freezing rain but that would be very
short lived). Note the warm nose aloft (+2 to 3C) and a deepening
near surface cold layer (-8 to -10C) up to 950 mb. Models also show
a good slug of QPF once the transition occurs, so this could be one
of those rare cases where sleet persists for several hours before
changing to snow as warm nose eventually cools. How fast this all
takes place is key as to how long it takes for sleet to change to
snow and obviously impacts accumulations of each.

At this point, we are becoming more confident that higher snow/sleet
accumulations will be north of Mass Pike, especially along and north
of Route 2 where 2-4" totals are possible. Totals should lower to 1-
3" along Mass Pike and 1" or less farther south, but keep in mind
these totals may need to be bumped up a little in subsequent
forecasts should colder trend continue on models. It`s also possible
that we see more sleet vs snow along and south of Mass Pike, perhaps
as much as 1-2" of sleet alone.

The combination of rapidly falling temperatures Friday could result
in a flash freeze and the transition to snow/sleet is expected to
result in hazardous travel. Since timing is centered around the
morning commute and into afternoon, and could have a significant
impact, we will issue a Winter Storm Watch for our northern CT,
northern RI, and all of our MA zones except south coast, Cape Cod,
and Islands (including the larger metro areas).

Note that icing from any freezing rain should be minimal (just a few
hundredths) and we do not expect any impacts from ice accretion
on trees or power lines.

The flash freeze is legit. That would be cool.

The model ma still have been slower overall with the cold push.

Yeah - definitely a warmer solution overnight in the low levels too. A much slower cold push outside of the GFS. 
 

Really would like so see some of the hires modeling get a bit colder sooner today.

We shall see if your 1-2 plain rain and 50’s work out. Maybe you’ll be right. I know where my money is not lol 

I hope I am wrong with over 1” of rain and upper 30s. If I could sign for mostly sleet, I would. I just don’t see the cold push until late in the game and by then, it’s not that eventful. I do think the flash freeze potential is real though and something to keep an eye on.

For south of the pike, it probably matters less how warm it is initially and more how heavy the precip is after the cold push gets going...but this is certainly not a cold start to 12z.

The orientation is more SW-NE, which limits the cold press coming in prior to precip. meh.

Maybe we get a cold push today by that arctic front?  Would be nice to see. Not much has gone right here these late two systems, so apologies for some of the negativity.  But I’m not encouraged currently with the trends. Maybe that changes today?  I’ll sell any real ice that’s for sure. That is always very elusive. Sleet more probable. 
 

The possibility is there that the Euro could be way wrong again with this system, like it was here for Saturday’s storm. 14 hrs before Saturday’s storm started, it gave me a raging blizzard with 18+ Inches coming, then 6 hrs later it pulled the rug.  I suppose it could go the other(opposite) way with this too.
