wow so the generally accepted method now is to only measure snowfall at the end of the storm (or when it changes over in case of a mixed precip type event), Ray? I wonder how this affects past storms.... how much did you measure in the April Fools Day storm in 1997 and what method did you use for measuring it, Ray?

Funny thing is that was a winter with very little snow, all the fun began later in Spring. One of our weirder years! What caused that arctic outbreak accompanied by snow in May? Did we have some sort of big SSW? I was in the Poconos for that we went from rain to snow Friday night and 1-3 inches and then snow squalls all day Saturday with an additional inch. The temps were in the teens for lows and in the 20s for highs with wind chills near 0! Then spring came back by Monday and we had thunderstorms with hail! One of the weirder but fun weekends I've experienced in May. We had snow on May 9-10 1977 and this happened on the 43rd anniversary of that, which was also interesting.

I'm wondering if we had these in the 1910s? There were extremely cold and very snowy strong la ninas back then. Also, was 2010-11 like this? That was a very cold and very snowy stronger la nina that had people looking at analogs from the 1910s.

Oh wow then they want to protest lol. I remember that happening a few times and the other thing is when the fans sit in the rain and the game doesn't get canceled until 3+ hours later and it's been raining the entire time.

Thanks! I've also noticed they have problems with drier snow that happens in windy conditions so a lot of our big blizzards get undermeasured. We have several examples of this both more recently and in the distant past. February 2003* January 1996* February 1978 February 1969* February 1961* March 1888 This is just an off the top of my head list, I'm sure there are many more. Sometimes we cross check the data with the airports to see what the errors might be. The ones marked with a * show significantly higher totals at the airports (JFK, LGA, EWR) than at the park. Of course there were no airports before the 1930s lol.

The Mets game that was supposed to be tonight has been rescheduled for 1 PM today. I've advocated for this for a long time now too. Like, in the spring and summer, if you know it's going to rain, why not schedule a game earlier? One of the most frustrating things about baseball is when you have an off day and the weather is nice and sunny and the next day it's going to rain and everyone knows it, and then you have two days off instead of just one. The game should be rescheduled earlier, to the off day the day before (if the other team also has that day off of course), instead of sitting around doing nothing for two days.

It sounds like we need way more than one axis to delineate the differences between different enso states. In other words, instead of recording weak/moderate/strong we should also distinguish them in the data west vs east based vs basin wide. It reminds me of the arguments made for nao needing to be defined as more than just positive vs negative, we also need to know whether it's west based or east based.

This is something I've always advocated for, use precipitation totals to account for snowfall measuring errors. I would use a sliding scale snowfall to liquid ratio based on temperatures. 8:1 for heavier wet snow, 10:1 for normal snow and 15:1 for dry and fluffy snow.

That's an interesting way of looking at it. I've always thought that strong of both is really bad and what you want is a weaker version of either so other factors become more important.

Yes, I love fall baseball.... looks like the Tigers and Yankees will both be good enough to play deep into Fall. We had some snow here on parts of Long Island before the sun came out, it really feels like winter here today with temperatures going below freezing tonight. It's the latest it's happened since 2014, when we had accumulating snow on April 16, 2014. We had snow on May 9, 2020 but the low was 34 on that date. Ironically our last freeze that season was in early March lol.

You know what this reminds me of..... anomalous heat bursts! I think this is absolutely fascinating, widespread reports of crops burning, even trees and people's doors burning with temperatures of 140 degrees or above for very short periods. Koppen Texas had such an experience as have many other locations around the world. The highest temperature ever recorded in a heat burst was 189 degrees (!) These aren't considered part of official temperatures records of course, because they are very localized. But they are real (and the burnt crops and burnt wood on trees and doors are evidence of it.)

How many months have we had at or above the +1.5C threshold?

we broken through the +1.5C threshold but it won't be recognized until we get a full year of this, so wait until the end of 2025 I guess to confirm it.

But do you feel the same way about weak el ninos vs strong el ninos? Just using deductive reasoning, we can surmise that weak phases are usually best because they do not interfere with the overall pattern as much and thus other factors (like nao state) are allowed to take over. With a strong el nino (1998 for example), you can have a -nao all you want, but the winter won't be snowy because enso overwhelms the entire pattern. The same should be the case for a strong la nina. It's also interesting that la ninas that come after el ninos are snowier, perhaps because the subtropical jet from the previous season's el nino is still actively supplying moisture for that snow?

wow, the sun was out here, maybe the sun will cause instability that will lead to sleet/snow?

When was our last freeze after April 10th.... 2014? I distinctly remember that snow we had on April 16, 2014. Also, it's strange that our last freeze in 2020 was in early March and yet we had snow in May 2020!

So late 1800s into mid 1900s snowfall was under measured by today’s standards. This is absolutely amazing because we were already averaging around 35" of snow per decade from the 1860s through the 1910s..... so this may actually have been over 40" And the decades before the 1860s were even snowier!

weak la ninas are our second snowiest ENSO state.

lol the pattern of stars actually looks like the liberty bell.

It definitely feels like winter today and everyone is going below freezing tonight.

Looks like the game tonight has been pushed back to during the day. It feels like winter today lol.

Did you notice this record-- higher than the hurricane of 1938!! and in 2010 they set a new heat record on this date (we all did lol). 1988 - High winds in the Middle Atlantic Coast Region gusted to 172 mph atop Grandfather Mountain NC. Twenty-nine cities in the southwest and north central U.S. reported record high temperatures for the date, including Yankton SD with a reading of 91 degrees. (The National Weather Summary) (Storm Data) 2010 - A temperature of 80 degrees is measured on Grandfather Mountain, NC, the warmest ever measured in April and three degrees short of the all-time record high for any month.

snow down to Houston is pretty amazing, perhaps Florida had it too?

wow in 1857 we had snow in every state on this date?? thats pretty amazing!!

Yes, esthetics aside playing in Pittsburgh and Detroit wasn't a good move lol.
