Its the 84 hr NAM gut that is a lot of DPVA throughout the day Monday (seem better animated of course) And we're in the left exit region of this monster jet streak

The coastal front is going to be insane. I think we know where the jackpot zone is going to be

yeah not sure if its a cod thing but its a little funky in that regard. but thats the type of lift we want to see!

Oh here we go...northeast CT right along the RI border. This is it

Going to be a hellacious fronto band moving through

Nothing loads for me either I forgot all about his page...his site used to be my go to for soundings back in the day.

Yup...great point. I'll say too...looking around at various locations, I would like to start seeing some stronger omega values popping up on some of these soundings. It's easy to get carried away with ratios given everything but we aren't going to automatically snag very high ratios because the DGZ is deep and its cold. There are really a ton of details to go over and analyze on this

Ratios will def be great up that way...the average should easily be in the 15:1 to 20:1 range up there and probably upwards of 22:1 to 23:1 during peak intensity.

If that Monday snow verifies I think someone in northeast MA may pull >24" I would not forecast that now but I think there could certainly be some reports. This storm is going to be full of surprises...I can't get over the whole DGZ thing looking around on bufkit lol. I think dendrite mentioned this about the snow ratios and how its difficult to maintain upward of 20:1 - 25:1 but where and when the best lift is occurring...there is going to be a swath verifying those ratios at least for a brief period of time

I like the good ole fashion wood

I could picture the NAM ending up with one of those runs that produces 1.50-1.75"+ of QPF. I really need to get to Lowes and get those yard sticks. Might have time to go Saturday, hopefully they'll have some in stock

Nothing to whine about so people unsure of what to do

This is why I can't wait until we get into meso model range. The mesos I think should handle this very well and this is when we can really talk about the potential for >15" totals and where those would be most likely to occur.

Nothing good comes out of doing that. You can raise awareness and prepare the public without having to go off the walls

If we're going to be looking at something along the line of 15-20-24" somewhere that idea won't become more serious until we're inside of 24-36 hours and can start diagnosing banding more accurately and getting a solidified feel on snowfall ratios, lift, etc. This is why that map of 1-2' was absolutely stupid this far out.

That would be a huge hit on the GFS, especially with the 850 low developing just south of the region. I like how the sfc low and 850 low go virtually west-to-east to our south with a bit of elongation to the low...that should help (I would think) result in a much wider than usual fronto band (combined with other factors of course) than usual. This inflow oof

For old times sake can we have the storm mode in bright red at the top of the page? maybe a radio show too

I miss oceanstatewx insights with the NBM and its latest developments. Its not a bad source though I think it still has a quite a bit of room for improvement. I'm actually not entirely sure how it does with snowfall forecasts but I believe it can be a solid source because of its ability to bias correct

Ask the chipmunk it squashed

Only mixing between Sunday and Monday will be Bacardi with coke

It is feasible the immediate shore does experience some mixing. This is where its much better to look at forecast soundings then fixed levels (such as 850 or 700). You can get very sneaky, subtle warm layers. There are also other processes to consider as well, for example, if there is a tremendous amount of latent heat release ongoing that can negatively impact snow growth production and result in poor enough snowgrowth that precip is almost sleet like. I believe something like that happened in 2013?

Just wait until we get the ice storm warnings cranking

Given the airmass, the trend could actually be a significant benefit to us, at least on the mesoscale level when it comes time to pinning down banding and what the potential amounts may be

Oh wow look outside and a nice, steady snow falling

All the details and such can be ironed out as we get closer but there is a ton to be excited and happy about at this time range. There is going to be no shortage of moisture with this and if we can get the final evolution to be very close to what the general consensus is, it's going to be a big hit over a very large area - obviously there will be mesoscale factors at play which result in some getting "screwed" and some "overperforming" but lets keep this signal for a powerhouse of WAA feeding into the airmass that will be in place, and with the thermal profile and temperature gradient (upward) velocities would be great over the entire area
