Approaching 9PM local time, temperatures in the London heat island are still well into the 70s. Clouds are hanging in from about Sullivan and Ulster counties N&W and where it has remained cloudy temps today have held in the 30s. For the rest of us, most have nudged past 50 in bright sunshine. OC is mostly splitting the difference in the mid - upper 40s. The temperature drops steadily and rather quickly heading west on 17 from the thruway. 52 here.

Ouch:

Looks like LI beat Greenland, but that's about it.

We hit 77 a half hour ago, but its a chilly 75 now. This is even warmer than it was in February (we hit 74 on 2/21). It's been almost 6 months since we were this warm (10/22)

27 low here this morning. Average low for the first 11 days of April is a hair below freezing. Only 3 days so far this April have had low temperatures above freezing. Some of the days had 11:59 pm lows. The only snow left is in old parking lot piles.

In the end, it didn't suck.

April 7, 1990 in West Babylon:

On the average, the land tilts north north of the morraine, but there's something more to it than that. Maybe better freezing at night? By the way, the main reason the snow melted out faster in Nassau the other day is because they had an hour or two more sunshine...and that hour or two was right in the middle of the day

There is something odd about the snow measurements at ISP. They've been raking it in but it disappears very quickly. The difference in 2014 is especially noticeable. I am 10 miles NW of ISP and here are my stats for comparison: 65.1"....42 days....2018 67.0".....62 days....2015 68.0"....64 days....2014

April 6, 82 was more like this year's January 4 blizzard than any of the other storms that we've had this winter. In eastern Nassau there was some sleet at the start, particularly on the south shore (8 AM-ish, IIRC), but then an all out daytime blizzard. Blizzard warning went out with a late evening update on April the 5th. Gutsy call in those days that verified. it was one of those rare days when the kind of storm that just doesn't happen, happened. Then on April 7th, the high temperature at KNYC was 31 with high winds all day. Long Islanders woke up to temperatures in teens with a foot + of snow on the ground, high winds and blowing snow on April 7.

I wish I could remember where I read that, but I do recall reading the opposite. 500 - 1000 mb thickness is a surrogate for the average temperature in that layer, but how you get there can vary. If it's warmer near 500mb (but still well below freezing), that gives you a little wiggle room to keep the lower parts of the column cooler and have snow with a partial thickness of 544.

That's not bad for snow in the spring.

12:1 ratios here during the April 2 storm.

29 here. At least the snow cover won't melt overnight.
