The interior may struggle for 30 if it's cloudy. But even at partly sunny, it's probably like 34/22 or something like that. This looks like one of those deals where the coastal front separates air that is in the upper 20s and snow vs temps of 36 with rain and catpaws. Maybe if it comes down harder it gets to 32 on the warmer side of the CF. It is very cold aloft. NAM has like -10C at 850 over CC Bay.
