I have been burned enough in similar situations to this that I'm not really on board -yet- with most of the higher amounts, especially over the southern half of the swath.

Snow events in daytime with temperatures over 32 are extremely slow accumulators. Lots of melting, lots of compaction. Would be a good research paper/case study.

So with that, here's our opening bid. Usual track/amount caveats apply.

Seem to favor the more northerly and warmer NAM like solution over the GFS I take it?

Meh. Not necessarily in love with anything. More of a blend or lean to SREF, and then an adjustment down of raw totals due to soil temps, and daytime air temps over 32.

From experience, daytime, 32+ temps and forecasting more than 2" of accumulation leads to a bad time.

And it doesn't make a ton of sense to confuse the message with where the watch was placed at this time.

Plenty of time to fine tune/pick fights tomorrow.

Who's got a link to the Earl precipitation forecast webpage? I got a new computer and didn't save my favorites. :(

Well, I'm getting gas for the snow blower tomorrow. I hadn't even winterized the lawn mower yet since I thought I was going to get another round of leaves first.
