Two Mdt to high impact events NYC subforum; wknd Jan 6-7 Incl OBS, and mid week Jan 9-10 (incl OBS). Total water equiv by 00z/11 general 2", possibly 6" includes snow-ice mainly interior. RVR flood potential increases Jan 10 and beyond. Damaging wind.

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.- 3,610 replies

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.- 3,610 replies

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.- 3,610 replies

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.- 3,610 replies

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.- 3,610 replies

This setup has been appearing in multiple ensemble members for days now.

With the 50/50 low set up like it is it maybe the NE crew that has the most to be concerned.

Let Walt do the thread for this one.

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.

A SSWE represents the start of a pattern change. It is in no way a guarantee of a long term cold and snowy pattern. I will describe the issue in a simple manner. Over the past several winters we have seen the establishment of a very strong west to east jet stream over and across the northern Pacific Ocean. The significance of this is that it prevents the sustained formation of a ridge over the western states which would deliver cold air down to us from northern Canada. This said jet stream literally blows away this ridge before it can get established and covers the country in mild Pacific air which is too mild for snow. This was the issue last winter.

FWIW there have been other periods where NYC had snow amounts of less than 20” over successive winters. These include: 1899 - 1901 1927 - 1932 1949 - 1955 1961 - 1963 1974 - 1975 1979 - 1981 1987 - 1990 1997 - 2000 2006 - 2008 None of these winter periods featured seasonal totals of 20” or more (I am referring to the seasonal totals experienced during these years and not the entire period shown). Many of them were 15” or less. These numbers are from the NWS Upton website. Unfortunately for the weenies it is a part of the climatology here that we do in fact experience successive winters with meager snow amounts. I would have hated to be a weenie in 1949 knowing that the next 6 winter periods would all have less than 20” of snow.
