Hi Rob. Do you have any information on low humidity records? I seem to recall a 10 or 12 percent humidity reading several years ago, but I don't think I've ever seen any records. It would be interesting to know the record low humidity by month, for example.

Rob

Hi Ken, information about humidity is available but it's inconsistent. It can be found in the monthly Local Climatological Recap where it's shown in 3-hour intervals; additionally, there are monthly averages by hour. But then, annoyingly, there are gaps in years in which none of this information is shown. Interestingly, in the years before 1950 hourly humidity is reported as well as an overall monthly mean. (For some reasons these old reports have a lot more granular information, which seems peculiar since you'd think we'd have the means for so much more in the present.)

Thanks for your question!

Hi Rob, I see I posed a question already on this date, last year. I have another one if you don't mind. I remember that snowfall in 2000 a day after the 71 degree reading. We had about 3 inches here in NJ. Is there any way to determine if that was some sort of record, i.e 70+ degree reading followed the next day by measurable snow? I was actually wondering about that when it happened.

Thanks for the blog, as always.

Rob

Hi Ken, another weather pal of mine compiled a chart on that very subject, and you're right, that is the warmest temperature to be followed the next day by a snowfall of an inch or more. However, perhaps as impressive or even more so was a 5.5" snowfall ten years ago, on March 16, that followed a high of 67 the day before. And, of course, this past winter we had 9.4" of snow on 2/9 the day after a high of 62.

Thanks Rob. As I said, I actually recall wondering about this back then and discussing it via Email with a friend who's also a weather buff but based in Seattle. After 16 years I now know the answer. Thanks again!

Edit: Obviously that should be 17 years, it's 2017 now. Time flies...

This was the third day in a row with a high in the 30s, the most days with highs in the 30s in April since 1881 and the most days in a row since that exact year which had five days in a row with highs in the 30s, both the most consecutive days with highs in the 30s in April and also the most days in April with highs in the 30s.

Obviously, in two consecutive years, 1999 and 2000, the temperature sharply dropped between 4/8 and 4/9. In 2010, there was a similar phenomenon, as 4/8/2010 had temperatures in the high 80's, whereas 4/9 was a MUCH cooler day (It was a dreary Friday with light showers falling on and off.)

Rob

The hot day actually occurred two days before the cool down (92 on 4/7, the earliest 90 on record). 4/8 was still unseasonably warm but it cooled to 80. And even though 4/9 had a high of 68/44 this was five degrees above average.
