IMHO, the biggest threat locally will be potential landslides over the next few weeks. Winter soil combined with above average rainfall and mild temps could be a problem.

Snow board measurements are usually more than in ground post storm measurements.

Was out earlier around 130 here in Mt Lebanon, and measured 7.5-8” in a few open areas. So with that back side energy coming through Indiana, an official NWS storm total of at least 12” looks doable.

30-35 dBZ returns coming out of southern Ohio and W.V. Probably 1.5-2.0” rates for some folks later on.

18z Guidance is fully in agreement on a high end warning event. Kickoff/nowcast in about 6hrs.

6z euro sounding looks pretty efficient, based on a quick read on pwats and snowfall.

For me it’s a bit of PD2 and 2010. Both had strong WAA snowfall.

WSWarnings from Mexico to Montpelier. Impressive

For almost a week now, the GFS has been pretty consistent with a high qpf event for that time period. We’ll see if all of the guidance starts narrowing in on a solution by at least Wednesday.

Since 1900, out of the top 20 December monthly snow totals, only 2 of those seasons were below normal. So that’s a positive sign.

12/9/92 might be my favorite storm, mostly for the nostalgia.
