How cold does the 950 need to be to produce sleet. It goes below 32 here  between 30-33 hrs. not much more falls a little more than .10-.25 dependeng on when in those hrs it changes

Ideally you would want 925mb to be around -2c if 850s are between 0 and 2c

Euro looks like another step back for the New England crew, mostly just a lot of front-end type overrunning precip that stays moderate and the CCB forms too late. Maybe a few inches in Boston this run it looks like. For us, the city and east look to have a moderate rain event.

This looks to be either a non event or rain. This does not look conducive for snow for Upton's warning area. The only potential would be from dynamics of a bombing out system, which appears unlikely at this moment.

We've been out of it since day one. :lol:

 

I knew to give up on it when the Euro killed our chance like 4 days ago. Upton's area doesn't do well with a huge primary over the Great Lakes and a slow developing coastal. The people with some chance left mainly reside from Worcester on east.

Exactly, when that primary hangs on into the Great Lakes, Upton is significantly influenced by the Marine Layer. Combine that with a 'lazy' coastal and well the flowers will be happy ;)

Check out the almost comical differences on the NAM from last nights 00z run to todays 18z run valid at the same time

The NAM has been complete garbage this winter, and that's putting it nicely. But most other models have also been not progressive enough 3-4 days out.
