I'm thinking about the same depending on final track, Low side if its more NW, High side if we get another tic or so SE.

I told my mom 8-14” for now. 

 

Sounds reasonable. Maybe I'll compromise and go with 8-16" when chatting with co-workers tomorrow. That's a good starting point at least, depending on how far the sleet line make it northward on models.

Final at Live from GTG on Saturday.

I see blizzard potential with some n stream trends, but not ready to go there yet.

Nice map I wish you well. Seems early to pin down amounts. Everyone here is downplaying qpf, why? I haven't heard any scientific reasoning

1.50-2.00" of WCB QPF seems a bit excessive. Get those totals inside of 48hr and maybe I'll start buying it. Ditto that with the ratios. If we get consensus for good lift for a prolonged period in the DGZ then maybe I'll entertain something more than 12:1 for the event total. But in those euro 850-700mb max T in the profile maps Ray posted it even gets up to around -3C up here. So the mid-latter portion of the system will probably have lousier growth. We'll see over the next couple days though. Maybe this will be the exception to the rule.

Thanks for the write-up, Ray.  Do you have a separate accumulation band in the north (where you just show snow) or are they captured in the 8-14"?

Good luck!

Historically high precip events. We will see.

Very reasonable and  knowledgeably cautious.  Good warm up event for the next 8 weeks.
