    I've been seeing reports of models predicting a storm for several days now, and the models are firming up. Weather Underground has coverage here, while the Washington Post is predicting two feet of snow coverage in the DC area.
    Key points:
    • This is long-duration event, with snow forecast for 36 hours or so.
    • Models are converging on storm onset in the noon-to-5 p.m. period on Friday.
    • Conditions are the worst after dark Friday continuing through Saturday night.
    • Thunder snow is possible Saturday.
    • Winds may gust to 40 mph on Saturday, causing whiteout conditions and some blowing and drifting snow. Strong winds east of the District toward the bay.
    • Biggest forecast uncertainty is near and especially southeast of the District, where there remains some potential for a dry slot that would interrupt the snow and potentially result in a brief changeover from snow to sleet, cutting down accumulations.
    [Metro trains and buses will close all weekend]

    If you're flying to that area of the USA this weekend, onward travel could be a problem.

    From out there on the moon, international politics look so petty. You want to grab a politician by the scruff of the neck and drag him a quarter of a million miles out and say, ‘Look at that, you son of a bitch’.

    Anyone want to follow it through out the day you can on Earth cam.

    A bit of lamp post watching in Belmont, NC http://www.earthcam.com/usa/northcarolina/belmont/?cam=belmont

    As it moves north just find cam location here http://www.earthcam.com/network/

    Follow progress also on accuweather radar http://www.accuweather.com/en/us/virginia/weather-radar?play=1

    Could be historic, especially for DC

    Thanks very much for those links Yorlum, in the first one it's snowing at the moment it will be very interesting to keep checking in to see it's progress.
    When we can't get this weather ourselves it's good to watch it unfold in another country.

    Also just a question, does anybody know of any similar sites to this one in Washington DC where I could follow a discussion of the weather as it progresses today? Slow day in work, obviously :P;)

    Or if any of our boardsies are living in/visiting Washington DC at the moment, if they could post updates and/or pictures, I'm sure the rest of us would be very appreciative. :D

    Am I right in thinking that much of the US had unseasonably warm winter temperatures until quite recently?

    In December in New York on the warmest days the temperatures were in the low 20'sC.
    When they should be wrapped up to stay war, they were in t shirts and shorts.

    Worst affected areas by the snow storm will get 3 feet of snow according to CNBC.

    Christmas Eve was shorts and T-shirt weather here (just outside Philadelphia) but the last few weeks have been very cold. Struggling to get above freezing point during the day, and regularly getting down to -10C at night. With the ground so cold, the snow should stick.

    I have a family member, who does not like snow at all, in the area predicted to get over a foot of snow. How i wish we could experience such an event in this country. It is good to see heavy snowfall, but it's just not the same as witnessing it at home

    Wow unbelievable to go from one such extreme to another so quickly! I'm so jealous. I know it's going to be very hard on a lot of people too though. Feel a little guilty about that when people struggle and suffer. It's easy for those who have means and are younger.
    That said my eyes will be wide watching the footage. Sounds like my kind of fantasy.

    BBC weather has said this storm will reach British Isles by Tuesday, any potential for an event?

    Been watching a Webcam of Time Square and the poor city workers trying to clear the paths.

    He did a good job when I checked 2 hours ago but now I see he wasted his time.

    The only potential we will get from it is mild and rain, we are back locked into the same pattern of muck that we suffered for months although hopefully the rain wont be as bad as what we had during the first half of winter.

    If you're looking for a technical discussion of the storm, the NOAA Storm Prediction Center has a good one here. Simple version: warm moist air from the Caribbean is being pulled north and pushed on to the East Coast by an anticyclone that's somewhere over Newport News at the moment. When that moist air rides over a layer of cold air, the moisture condenses in to snow at the boundary and drops out:
    SPECIAL 06Z OBSERVED SOUNDINGS FROM WASHINGTON-DULLES AND NEW YORK CITY SAMPLED A SATURATED THERMODYNAMIC ENVIRONMENT CONDUCIVE FOR HEAVY SNOW WITH ESSENTIALLY A SATURATED DENDRITIC LAYER AROUND 500-600 MB AND AN AGGREGATION-CONDUCIVE NEARLY ISOTHERMAL THERMAL LAYER BETWEEN 700-850 MB. COLLOCATION OF AMPLE MID-LEVEL FRONTOGENETICAL FORCING AND WEAK STATIC STABILITY...WHICH IS LARGELY RELATED TO THE NORTHEASTWARD-SURGING MID-LEVEL DRY SLOT PER WATER IMAGERY...WILL SUPPORT MULTIPLE WSW/ENE-ORIENTED INTENSE BANDS OF HEAVY SNOW.

    There's a report of drivers stranded on I-75 in Kentucky overnight, due to ice.

    That is something else.

    One day I hope to be in the right place at the right time to experience something like that. It would be utterly amazing.

    The BBC now has a nice photo gallery, here.

    NYC travel ban was from 14:30 local, I believe - 1/2h ago. There's more snow to come overnight.
