According to Upton:
High res models indicating strongest mid-level frontogenesis
develops to the north and west of the coastal plain Wed morning
into early afternoon. This will actually have the highest
likelihood and intensity of precip to develop across Interior
portions of NE NJ, Lower Hud and SW CT Wed morning into early
afternoon (thermal profile plenty cold enough for snow). With
that said, can not rule out that this development could be a bit
farther south into the coastal plain (although a lower
probability). Most indications are for snow development to hold
off until mid morning or later.
