Since you mentioned this I wanted to give my thoughts on this one. There is definitely a moisture surge that comes north Monday into Tuesday, but it comes north with a modest LLJ, weaker than one would expect and the system isn't overly strong. What is good about that is the WAA would be weaker than expected, and with a cold dense air mass in place it would be slower to get shunted away and that's without factoring in a decent snow pack that gets added to today into tomorrow. I would say I could see a colder solution barring a dramatic change, and the GFS is definitely leaning that way with a solid snowfall on Tuesday with some ice along I-80.
