I think it started out near freezing early that Sunday morning. At some point it dropped into the 20s. Some of the old newspaper photos from western LI show insane drifting.
Woke up to about 5" of fresh powdery snow this morning near Jackson, NH. About to head for the LI ferry; we're catching both storms
No rain or freezing rain during the February 1978 blizzard (except possibly right near Montauk for a bit, but I'm not sure). You might be thinking of the big January near blizzard that year which ended as a mix.
Temperatures prior to the Feb 6 storm were very cold (near 0 on LI the morning of the 5th) and well below freezing except for a couple of hours late on the 6th from ISP south and east as they got involved with a coastal front and the temp rose to around freezing.
We had snow up to my keester but my most vivid memory is the wind; it was insane.
Only need gusts to at least 35 for 3 consecutive hours. There's a visibility parameter as well. That's why there can be blizzard conditions without a cloud in the sky.
Perspective; affects of this storm won't start to show up in the far reaches of the short range models until tomorrow...and many like to say how worthless they are at that range. So having canceled and/or uncanceled this storm multiple times in the past 24 hours is head-scratching stuff.
I think the snow will have trouble accumulating on the old snow pack, especially since temperatures are now falling back towards freezing. The new snow will rapidly melt the old snow.
