Might be a long shot, but if it did happen that would support the flash freeze on the roadways. Lots of parties on for tomorrow evening. Would be ugly.

Christmas maybe, but there was a decent snowstorm around the 10th of December 1982 so it wasn't a shutout. I think it was one of those memorable Patriots-Jets games played in that storm, but I might be mixing my football folklore. There was also a big snowstorm around the second week of January 1983 (15th?) that went over to rain for a while along the coast, but left accumulations almost everywhere. Pretty big difference from LI south shore (where mostly rain) to north shore in that one. Even more snow on the Connecticut coast and a lot inland where there was no rain. Plus 5 or 6" that ended as some rain or drizzle about a week before PD1. Scary how I remember stuff when I was young better than stuff from last winter.

@bluewave I've been thinking that for a couple of days. Maybe for friends of ours in East Falmouth too. (CC)

I did do a lot of cross country skiing before Christmas 2 years ago. That was nice.

I wouldn't count 97-98 as a backended winter. There wasn't any winter that year, just a rainy season. However, 4 of the last 10 winters qualify (5 if you include 2015). I refuse to give up on cold snowy Decembers, but I'm an optimist.

They're hard to come by in Florida. I've seen quite a few here. Most were associated with an artic cold front passage accompanied by snow squalls and I don't recall the dates. Others associated with more notable low pressure have been mentioned here (2\76, 3\2005). One thing they have in common is a minor snowfall accompanying the temperature drop. Without precip, the roads tend to dry out. They haven't been common over the past few years, but when you have to be out when a flash freeze is occurring, it will leave a mark.

I might have been confusing 1980 with 1983. I don't think the Yorktown 24 hour period is midnight to midnight. Maybe 8am to 8am? Here are hourlies from KSWF. This isn't error free either...I think most of the 0° temperatures are a stand-in for hours that the temperature is not available. Also, no precip...just sky conditions.

That's what happens when I don't post much in the summer. I miss all the important terminology changes. Is weenie still a word?

If there is no snow on the ground beforehand, is it really a Grinch storm?

It did stop abruptly on the snowfall map you posted, probably because of rendering problems with the graphic. The only time I can recall something that looks like the quoted map in this post was late February 2010. The low west of the Catskills must be stacked and occluding, but that's still a whacky deform under the circumstances. Model roller coaster seems likely to continue.

Those temperatures are off by a day. The 12/25 temperatures are actually from 12/24 and the temperatures shown for 12/26 are from 12/25. Of course that might be dependent on what the observer considered the time of observation.

15" in South Amboy and nothing in Metuchin. What's so strange about that?

I remember waking up to that. It was the first snow day in my school district since 1969. I have some old Central Park ob's...peak wind gust was 59 mph and temp dropped from about 35 at 5am to 11 at 9am. Temp didn't budge from the low teens the rest of the day.

Not to dredge up old trauma, but the mix line was super close...right over LI for the first part of that storm. We barely had any rain here at all, less than 0.2" of rain/sleet out of about 3.87" LE for the storm. We had a mix, then some light rain for a short period late morning then slowly accumulating light snow for a few hours before it went nuke late afternoon. There was also a short period of sleet mix a little after dark, but not much. South and southwest areas of the island did get a bit screwed, especially since it was such a close call.

Jeez. So much for not hitting cities.

3 or 4 inches of low density snow over unfrozen ground is not "snowpack".

0.6" here. Streets were completely covered early this morning but it has since melted off the pavement. Snow on the trees...pretty morning.

32F very light snow At the moment, it doesn't look like anything better is going to find it's way north of the Expressway.

Flurrying in north Smithtown.

Noticeable band of OES (OER?) south of LI into the central Jersey coast (south of 195), but it's probably just drizzle on the Jersey shore.

That's a good point. The color differences are so stark that you can lose track of what they mean. My location is in the skunked area but if you look at it closely, it's 70%. Not shocking that it's less than inland, but not a suicidal difference. Another way of looking at it is that there is a 28% higher chance of this outcome away from the immediate coast.

That spread looks great. With the HP oriented the way it's depicted, boundary winds would be more N than NE for most of the individual members.

12/31/62 Central park low temp was 4 and max was 13. Downside: only 16.3" snow winter of 62-62

Is this your forecast for Christmas morning temperatures?
