What an awesome event! What a refreshing escape from gloomy news and no home team worthy of rooting for. Widespread 3-6" across much of northeast CT / MA pike region / RI including Boston metro is a lock. There was understandable guardedness of those soundings posted yesterday ("we struggle to get these soundings in some January events"), but the cold delivered. The mesos nailed this.

Eyeballing >2" in Brookline near Coolidge Corner, will measure when get a chance

This never gets old! And drooping trees with leaves covered in snow... amazing sight! Eyeballing 1-2" in Fenway 13z HRRR has some of the best soundings 17z-18z in Boston metro, let's see if that materializes

Gonna be a fun few hours tomorrow morning... we've struggled to get these soundings in some January events... Nice pre-season warmup

I and probably eveyone was too exhausted to do a post-analysis... thought I'd toss up some tired and probably incomplete impressions. I went back through model runs in the 48 hour leadup and compared to the obs map above. Thought this was a clear NAM winner. Feel like it's had a good season. Very clear banding signatures that happened. Euro was good too. The old EE rule and ignoring all the other model noise would have given us the best handle of this particular storm. Most guidance wanted to jackpot southeast MA, but between mid-level processes generating bands further northwest and initial boundary layer issues southeast, jackpot ended up in the 495 corridor and extended further north than most expected. RGEM was spastic and more wrong than right. GFS was a national embarrassment, pretty much ignorable. Ok with SLP track, but qpf depictions and thermals were a joke.

Per usual, an anomaly compared to every surrounding site. I'd expect most sites in the immediate metro area (Chelsea, Revere, Hyde Park, South Boston) near 15" after that 5-7pm band. Some other nearby reports: Somerville 19.9 733 PM 3/13 Social Media Revere 15.0 632 PM 3/13

Just returned from a weenie walk around Coolidge Corner... AWT that band did not disappoint! Beautiful out there! Judging from rate of accumulation of freshly plowed pavement, that band reached rates 2" / hr. Amazingly fluffy snow, and notable lack of strong winds. I think we and Boston metro area end up 15-18" when all is said and done.

Nice from Box... this is a healthy and slow band, 1-2" / hr incoming for Boston metro folks... this should get everyone into the 15-20" range:

Finally for Fella / SR Airglo / SBosWx and others in Boston metro... it's been like watching paint dry for improvement in flake size for past hour but we are finally tasting the edge of the meat... she's fading but there are solid 30+ dbz returns... at the rate it's moving, this looks healthy for next 1-1.5 hours at least H7 fronto:

And quickly. You can see how quickly roads get covered after they get plowed. Helps that we cooled to upper 20s too.

Agree... just probably more out between 128-495

18z RAP run gave Boston area another 4-6"... that band, though less robust, looks decent and will deliver. Intensity and flakes already improving. When all is said and done Boston area will probably end up 11-15"... nothing to complain about... is great by Sunday's expectations, and only by yesterday's 20"+ runs does it seem like a bust

Remnants of mega band have breached 495 wall... ticking east... I think by 4pm Boston area will be singing a different tune

Probably does not include the Worcester area post-deathband

We lost at least 6"... We'll still pass a foot in Boston... those bands gotta exit somehow

About as sharp winners and losers as you can get... it's coming down in Boston metro but snowgrowth is awful We know these bands must come east, question is in what state and rate

Banding delivered... 8+ hours to go?

I wish we could dissect and explain mechanistically each one of these bands, some awesome processes underway

Boston folks that mega band to our northwest looks to be decaying and maybe reforming over Worcester? We'll get our turn... all that will collapse over us, and in the meantime watch that sharp process to our east incoming...

Jay that very sharp feature is interesting, looks to correlate well with northwest edge of H7 frontogenesis?

Mega band just outside of 128 has signs of expanding east into metro Boston...

Kohx afd catching up to the model trends mentioned earlier... adding in chance of some cirrus blow off of storms in Mississippi valley. Not the end of the world given soupy airmass, and still think there's room for this to trend great vs. good for BNA. I feel like it's January writing this: we want that 0z Fri GFS / Euro solution back!

Was thinking of photos with black hole in the sky behind... how will you angle your camera? The sun will be nearly overhead (vs. those shots you see with the eclipse near the horizon).

Key word might be "surprisingly" lol... I'm quite giddy. I'll PM you my cellphone #. Packing includes hardcopy road maps assuming cellular service will be inundated. Picking up rental at BNA, have to also pick up my brother, then we will head to motel in downtown Nashville. Not sure we will trial run to Gallatin though I'd definitely do that if I were alone. Monday AM early wakeup, plan to leave for Gallatin by 9-9:30am, and will adjust earlier if crowds are obviously insane Sunday night. Reminder for everyone to turn off cellphone service / texting etc so as not to get annoying distractions during eclipse. My only plan is to video record ~ 10 min of event on my iphone. Nothing distracting, no practice needed, no messing around with camera settings. Otherwise just taking in every second of the experience.

Not sure how these cloud prediction algorithms are done... weather.us and pivotalweather GFS trended cloudier for BNA area, entirely high clouds, though ridge placement looks about the same as the best run 0z Fri for GFS + Euro. Kohx sounded optimistic this morning, scattered ci + diurnal cu. I think we are in good vs. great territory. We'll take it and hope it trends even better in next day!
