2.5" on the board

which run, its been going back and forth between dryest and wettest run to run lol

QPF looks pretty lame and the energy is deamplifying as it passes and starts to re-amp a little too late for us... but at the same time it doesn't take much to get a couple inches from these types of things...if we get any banding at all we could get a nice surprise but I am not expecting too much. Maybe another 1-2".

Yea north of DC up into southern PA got stuck in between bands...the 85h associated band (which I never thought we were in play for much from) actually shifted southeast a bit and the 7h band shifted WAY north (which isn't uncommon recently, models really really really struggle and seem to place this way too far south or miss it completely) and left northern MD in between. Oh well. Happens, we still got some snow.

Actually as of 2022 analysis showed eastern Mass had increase snow climo due to bigger coastal storms. But the further south you go the worse that equation gets.

I think everyone has acknowledged we’ve been going through a convergence of a shit pacific and high latitude cycle which also happened in the 50s and 70s. The last 8 years would have been a snow minimum in any era. But we’ve used regression models and analysis to determine we’ve lost about 15-20% of our snow climo. And the results the last 8 years fall within that measure worse than comparable bad cycles. So I guess the issue is whether you think 15-20% is a big deal. I do! We’ve had several marginal events that would have made a total dreg under 5” winter into a more easy to stomach year that at least had a decent snow or two. No one is saying these would have been snowy years.

Ya I was there

I had tickets to that game. I was so mad. Missed the snow game then had to take a train back 2 days later from NYC where I had plans that week.

I was pretty sure it understood when we had our little chat the other day

@HighStakes the high res guidance is all tightening the gradient as predicted, but on the PA side of the border. We should be ok.

@mitchnick didn’t realize you’re like 10 miles north of me now. What part of Hanover, might make a difference here north v south side.

Latest hrrr

No it’s just about 1-2” less across the boards. Dryer.

Here’s the band we need to hope sets up for us in northern MD

The heavy precip in northern KY has my attention.

The one I posted is the latest rap.

Clear your cache or refresh. It loaded the old map. Just to clear it up the rap was sinking south the last 24 hours after being crazy stupid north yesterday at unicorn range for that model. The last 2-3 runs have started to creep north again.

Rap also creeping north along the PA line the last couple runs. We’re getting into range where these trends could be legit.

Latest Hrrr still has the northern banding and places it right along the PA line. Implies 6-8” there with a sharp cutoff 10 miles into PA. Another nowcast is to see how much if any minimum there is between the two bands.

Latest from NWS probabilistic

If the latest run isn’t hiccup it’s starting to look like my snow map lol. There would be another 1-3” after this.

Agree, have to know your climo. When I lived in NJ and NVA I used 10:1 most times. Up here I actually avg 15:1 or higher many storms if it’s cold.

I’m fairly confident that 6-10” band I’ve been expecting somewhere near or north of 70 will occur now. But how far north it sets up is gonna be the question. Guidance is now tightening up the gradient along the pa line. Somewhere within 20 miles either side is going to be victory and agony.
