North American Weather (U.S.A & Canada)

This low has 'bombed' 42mb in 24 hours and apart from possible extensive snow along the coast will also bring very strong winds.

Potentially Historic Blizzard Taking Aim on New England

 

The densely populated area from New York City to Boston could experience one of its ten biggest snowstorms on record early this week, as a textbook nor’easter takes shape over the next 48 hours. While local details are bound to evolve somewhat as the storm develops, the models are now in strong, consistent agreement on a potentially crippling snowstorm. Blizzard watches were hoisted on Sunday morning from eastern New Jersey to northeast Massachusetts, including the New York, Providence, and Boston metropolitan areas.

I was just thinking the very same thing.

 

Can anyone recommend any particularly good live cams in the affected areas please?

The obvious one for NYC is times square earth cam

[Buzz]

True, thanks. I'm sure there are many more.

Love the 850hPa temp differential. The difference in the USA is that with the colder dryer air undercutting from the north they will see snow with milder 850's than here:

Looks like a record-breaking snowstorm.

what a wonderful experience I know it is not for the faint hearted

Updated NWS (22z) forecast snowfall thru Wed afternoon. 26-32'' from NYC to Boston

Strong winds = 4-6 foot+ drifts

Talk of NYC seeing the worst snow storm in living history!

It's set to start this afternoon... This would be pure music to my ears if it was for the UK:

 

“This storm definitely has the capability of being not only historic but also catastrophic,†said Benjamin Sipprell, a meteorologist with the National Weather Service in Taunton. The weather service issued a blizzard warning in effect from 7 p.m. Monday to 1 a.m. Wednesday.

 

 

 

“People should be making preparations right now,†Sipprell said Sunday.

“This is going to be all-out whiteout snow, crippling everything. We’re highly advising no travel, starting late Monday, going into Tuesday and on into Wednesday.â€

I believe TWC are reporting live on this...will look on youtube.

Already Mets referring to Blizzard of 78 and this being a crippling storm.

 

ECM slower with the system and maintaining extra snowfall over New York, GFS churns up the coast more quickly. Hey - what's the difference - either 1 foot or 2 foot of snow, still blizzards ! Wow.

Good luck to them all, can't wait to see the images !

Thanks Lorenzo,

 

Remember the 78' Blizzard well, although it was much strong wind speeds then, consistent 90mph and reaching around 115mph if I remember correctly.

 

Still, this will be a lifetime event maybe for some.

Nothing "marginal" about the snow storm about to hit the NE USA.

Considering they deal pretty well with snowfalls 6-12inches on a regular basis, then to describe this strom as potentially crippling shows how bad it is expected to be. Having been in a snow storm which dropped 7-8 inches in Philly, I can vouch for the efficiency with which roads and car parks are cleared.

[lorenzo]

Dr Louis Uccellini calling for a grade 3-4 on the NESIS scale, similar form of category to how Hurricanes are ranked.

 

Translates as major storm, note worthy and historic.
