Wow, well I guess it can still happen. So the 5.0-5.9" storm that happened with the temperature at 33 degrees or above for the entire storm happened less than 6 years ago....

6 hour storm Don? that sounds absolutely amazing, the snowflakes must have been HUGE

also in April Don?

and I was amazed it happened in April, but it was almost 120 years ago....I'm not sure it could happen in the modern day of concrete lol

wow sounds beautiful and yet very very dangerous! I wonder if something like this could happen today? I see there was a 33 degree storm of 5.0-5.9 in there too, was that more recent?

THE SUN HAS COME OUT! YAY!

Hold on Don, we had a snowstorm that dumped 5.0-5.9" of snow with temperatures of 35+ during the entire storm? How is this possible and which storm was this and what was the snow to liquid ratio in it? Thanks!

so this was the second arctic outbreak in January 1994 that dropped NYC to 0F degrees...... and the temp rose all throughout the day until reaching 32F (or 0C) at midnight and then a raging southeaster the next day with 55 mph winds and temps in the mid 50s lol

if the sun comes out yes

so this was another storm that didn't drop anything here because it was suppressed: 1922: On this date through the 29th, a significant snowstorm struck the East Coast from South Carolina to southeastern Massachusetts. Washington, DC, reported 28 inches of snow. The heavy snow on the Knickerbocker Theater's flat roof put a significant strain on the structure. On the evening of the 28th, during a showing of the silent comedy "Get-Rich-Quick Wallingford," the building collapsed, killing 98 people and injuring 130 others.

This was absolutely wild in October 2019, I think we had a heat index of 100 on this day too? Was this the latest we have ever hit 95 and also our latest heat index of 100 too? I see NYC isn't listed here, was Central Park again being influenced by the foliage, Chris?

It's interesting about 2011 though, wasn't that one of our wettest years on record? Did most of that rainfall happen after we already had the big heat? That 108 degrees at Mineola is absolutely wild-- was that the highest temperature ever recorded anywhere on Long Island, Chris? So I could envision 105+ heat happening in this way Winter is usually wet so that would be hard to bypass. But let's say we have a dry spring which we've had the last couple of years. So warm and dry beginning in April and lasting through at least July. We missed it by one month last year because we had a warm and dry April-June (and the temperatures would have been higher in June were it not for all the wildfire smoke; we did hit 90+ on back to back days in April.) We started getting wet again in July, but if that could have just been pushed back one month to August and we didn't have the wet July, I think we could have had a chance at 105+ in July.

That's what I wondered about when London hit that historic triple digit temperature over the summer, what was the exact value in F lol

Yep, I see that on my weather station too, because when the temperature goes up or down there are "jumps" that correspond to 0.2F (but it's actually 0.1C measurements that are being converted to F).... once in awhile there is a change of only 0.1F but it only happens at certain numbers....and these just happen to be going from a change of 0.2C to 0.3C over the previous whole integer conversion from C to F. That doesn't sound so clear lol so let me illustrate. By whole integer conversion I mean when a whole integer C reading converts to a whole integer F reading. Let's take 0C = 32F as our example. so a change of 0.1C = a change of 0.18F or 32.2F when rounded to the nearest tenth a change of 0.2C = a change of 0.36F or 32.4F a change of 0.3C = a change of 0.54F or 32.5F a change of 0.4C = a change of 0.72F or 32.7F a change of 0.5C = a change of 0.90F or 32.9C you get my point lol Now notice the change of going from 0.2C to 0.3C If you round the F to the nearest tenth 0.36F rounds to 0.4F and the 0.54F rounds to 0.5F So in this case the next highest increment going up from 32.0F is 32.2F (because it's really increasing from 0.0C to 0.1C and that's an increase of 0.18F so in F this gets rounded to a 0.2F increase or 32.2F).... the ONLY time we see a 0.1F increase is going from 0.2C to 0.3C in that range because the actual value of the conversion is going from 32.36F to 32.54F, so the weather station will show it going from 32.4F to 32.5F. This formula works for every conversion I have seen on my weather station, the only time I see a 0.1F increment being used is when the conversion calls for it (a change of 0.2C to 0.3C from a whole integer conversion value of C).

ah okay so if the low was 32.4F on NWS instrumentation at, say NYC, that wouldn't be considered a low of freezing for that day? and likewise if the high was 89.5 that would be considered a 90 degree high on that day, Don?

Yeah we always lose something in the conversion lol. I can tell our weather stations measure in 0.1C increments and convert to F so the precision isn't 0.1F but it could be if the manufacturers wanted it to be.

The good thing about February is we don't need severe cold for snow, temps in the 30s would be enough.

Thanks Don, so does the NWS actually keep temperature records in 0.1C increments and the conversion to F is what results in the rounding errors? My weather station does the same thing, I noticed it's actually measuring in 0.1C increments and the F is a conversion and not an actual exact measurement.

Is this an omega block setting up early this year-- so we're getting shortening wavelengths a month earlier than we usually do?

Don, for let's say highs in the 30s on a consistent basis are you looking at Feb 10th and beyond or more like after Feb 15th? Also-- we're going to hit a landmark soon. When we reach Day 730 it will be exactly 2 full years since the last 2" snowfall!

we'll get some sunshine next week

I can't help but thinking it's an interesting coincidence that it hit 80 at Newark in February 2018 and then winter came back in full force a few weeks later and then today it hit 80 at DC and that winter might come back in a few weeks.

Simulated snowfall is THE BEST kind of snowfall.

Didn't parts of Long Island actually get 2 feet? Maybe Islip and points eastward? And that one observer in Orient measured 30" lol

I remember we had a heat index of 100 here when it hit 96 on October 2nd (I think it was in 2018?) and that was on the south shore of Long Island lol
