I think you misunderstood. I think around 5”, perhaps locally more for where the FGEN sets up, and 2-5” for the area outside of that.
Ultimately it’s not that different from the NWS map just posted, just slightly lower totals.
I agree the FGEN placement is key for areas north and would me the difference between 2” and 5”, maybe slightly more locally. Hoping for anything else is not prudent.
I almost consider the lake effect a different event considering it will be happening 12+ hours later and I’m not sure how LOT handles that. Perhaps WWA to lake effect snow advisory?
