Another tick SE...gets you into accumulating snow now. Just gotta keep up the act another couple runs and you'll get your 2-4"

It’s always had 1-2” here . In Mayorch though. You sell that without heavy rates even at night. Only a narrow zone will get 3+ and that’s been in that slot we’ve been mentioning

It all depends on just how quickly the CCB pops....even in an event like May 18, 2002, it didn't snow very long. The rates did pop big time though for a couple hours...and that's key. It was going at like 0.20" per hour in the bucket and that dynamically cools the BL pretty quickly. 0.08 per hour type stuff isn't gonna get it done for accumulation.

All models have trended further east and less amplified with the northern stream. That is what it causing the later phase.  This was similar to 2010 when models miraculously brought the storm back .

Not the likely scenario, but still worth watching 18z and 00z  in case somehow the NS trends back west again.
