    That will be dependent on snowfall rates. Penndot and NJDOT are usually pretty good with pre-treating the roads with brine and then salting during the event. These treatments will keep the roads mainly wet with temperatures as low as the mid 20’s.

    Rates do matter however the precip type is ultimately dependent on temperatures aloft.
  3. Tatamy
    It’s not based upon the elevation. It’s based upon the urban heat island effect. There can be snow with the event anywhere in the city however how much of it sticks is very dependent on surface temperatures. You then have to incorporate temperatures up in the atmosphere to this equation. Many models are calling for mixing or even a change to rain. Throw in the presence of a warm ocean and the nearby LI Sound. Many parts that play into this scenario.

    Your point is well taken. I was speaking in general terms. Make no mistake that if even if half of that accumulates on city streets and sidewalks that would be a lot. The fact that much of this falls at night will help. I used to work in the city on the west side and recall a number of times where snow was falling at the roof top level (six stories up) and was falling as rain at street level. It really does take a significant cold air mass to get accumulations especially in Manhattan.

    The 06z GEFS mean for the city is 6.8”

    The precip that you refer to will likely be quite light as the event winds down. In any case whatever snow does fall looks to get completely washed away with the incoming rain storm later Tuesday and Tuesday night into Wednesday.

    0z GEFS mean is for 6-8” for all areas from I95 and to the north and west. Two things stand out on the past 4 runs or so and that is the axis of heaviest snowfall is quite consistent in its placement. The other is the amounts on the mean have been gradually increasing.

    It’s actually a better run for much of NW NJ and SE NY than the 12z run.
  9. Tatamy
    01z NWS BOM has 6-12” to the north and west of I95 with lesser amounts to the coast.
  10. Tatamy
    18z EPS mean targets NW NJ, SE NY, and NE PA with about 6” generally. Lesser amounts down to the coast.

    It’s been years since I last watched that channel. My service does not even offer it.

    It’s easier to do than you think. Set up a YouTube channel and you can provide users with graphics like that shown above with commentary. If you reach 1000 subscribers you start getting paid.

    Northern NJ / SE NY Jackpot with 7-8” mean. Less for coastal areas.
  14. Tatamy
    Yeah that’s already been appearing on some of the model runs.
  15. Tatamy
    18z GFS is quite progressive with the following event moving in during the day Tuesday and it’s out of here by early Wednesday. It’s basically a rainer for everyone with 1-2”.
  16. Tatamy
    Still have about 48 hours or so until the NAM gets its first chance to start parsing out the warm layers associated with this event.
  17. Tatamy
    GEFS mean is a nice look for the area.

    We are going to have many runs with many different outcomes over the next few days for the upcoming weekend. We will see results ranging from big hits in the mid-Atlantic, a crush job here, runs with precip issues along the coast, and any combination of the above. We then potentially get to do it again during next week with a greater chance of a region wide change to rain. Nothing is currently set in stone for how this all works out.

    This setup has been appearing in multiple ensemble members for days now.
  20. Tatamy
    With the 50/50 low set up like it is it maybe the NE crew that has the most to be concerned.
  21. Tatamy
    Let Walt do the thread for this one.
  22. Tatamy
    Bluewave tells it like it is.

    Tomorrow will mark 700 days since at least 2” of snow was last recorded in Central Park (from the post at the beginning of this thread). I think if we get through January with this streak still going I like the chances of making it to 1000 days and then some before next years season.
  24. Tatamy
    Event total up to 2.37”
  25. Tatamy
    Now up to 1.79”. Still pouring.
