the flood watch is pretty much for ponding. It mentions urban and poor drainage flooding...some small streams to near bank full. I think it was yesterday that BOX/ERC ran a scenario based on 2" of rainfall and no rivers reached flood stage.

Again I would love to see those numbers, wonder if they account for little absorption.

Is it time to start looking at the RUC? lol

We've established that the RUC is horrific on coastal lows, how about Ohio Valley lows? I'm sure it just sucks in general outside of about 6-10 hours... but its got a fairly cold profile for several hours in MA north of I-90. At face value (which isn't much on the RUC) its like 4 hours of wet snow at the beginning north of the Pike.

You are obviously the professional and know your area well, Will, but I think you could do 2-3" on the front and another couple on the back.

Anyone with 1,000ft or more of elevation in northern ORH county though does look like a 3-6 incher before changing over. Hopefully it surprises some of you folks.

The RUC is usually too warm at this range in both coastals and SWFEs from the OH Valley. So its interesting that its showing a reasonably cold profile at 12-16 hours N of the pike. We'll see. I'm not totally sold on a several hour burst of heavy snow at the beginning, but its definitely a possibility. If the antecedent air mass was a bit colder at all levels, then I'd be a lot more excited about it. But the very dry mid-levels right now should be a plus...if we can get some big omega slamming into that then we'll see a lot of evap cooling and might be able to halt the snow line's progress for a few hours.

I'd feel a lot better if I was about 20 miles north closer to the NH border.

Obnoxiously frigid and dry all week and then it's done as the storm approaches.

I'm cautiously optimistic 10 miles from the VT border.

I'd be shocked if you don't see a net gain. You'll mix with pellets and might even change to a cold rain for a time, but you should get a nice pop of snow on the front end and then perhaps an inch or two on the back end.

Nah, you all get pounded in March/April. Pattern reset.

+1... though its probably not going to be able to rival the 1-2 footer that this area got on April 29-30th last year. Only time I've legitimately had a "snowpack" in May in a lower elevation. Skied 21" of fresh pow on Mansfield the last day of April last year... the law of averages says we don't get another big April snowstorm up here this season; but the law of averages says we are due in March.

I have 0 recollection of that taking place....shows you how completely checked out I was, by that point. :lol:
