You couldn’t ask for a better setup for the region given the last several years. Everyone wins in this setup. There really isn’t a screw zone. It’s a region wide dumping
Wasn't entirely sure I'd get to do into enough detail to make a forecast but alas I did.
I originally had the whole area of 12-18" but wanted to highlight that potential for some higher amounts in northeast Mass...I think that signal could be very real. Didn't want to go crazy and throw out 18-24" contour so just bumped 12-18 to 10-15 to add a 15-20 area. This is what winter is all about!!!!!! LFG!!!!!!! Massive snowstorm and a Pats trip to the super bowl incoming. Someone pinch me I'm dreaming

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
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 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
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.
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
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
