Looking Back at New York Weather: April 30

 

1874

The last three days of the month all had lows of 32° or colder, joining eight other days with lows this cold.  No other April has had this many days with lows of freezing or colder; these days contributed to this being the coldest April of all time.  (The following April and April 1943 would have nine such days, the second most.)

1925

Rainy (0.55" was measured) and very cool, with a high/low of 45°/42°.  The high was a record for the coolest maximum temperature on this date.

1940

Today's high of 67°, just a few degrees above average, was the mildest reading of the month.  (The warmest high temperature in April in the years before then was typically in the 78° to 82° range.)  In the years since 1900 this was the only April with no readings of 70° or warmer - until 2020.

1942

Today's high of 91°, a record for the date, followed a high of 72° yesterday and 53° the day before that.  The previous record for the date, 86°, was set just last year.  In both years, the humidity was quite low during the afternoon, at around 25%.

1962

After three days of summer-like warmth (highs of 91°-89°-80°), this afternoon was raw and showery with temperatures only in the upper-40s.

1963

Up until today, just 0.39" of rain had fallen this month, and it appeared it would become the driest April on record.  However, an all-day rain brought 0.89", and the month ended up tied for third driest April.  Until 2014, today's rainfall was a record for the date, which was the second smallest amount for a daily record (Sept. 9's daily record is 0.86", which was established back in 1902).

1990

Today's high of 56° (ten degrees below average) was quite a drop from 73° yesterday and 90° two days ago.

2012

The final nine days of April all had chillier than average temperatures - the longest such streak since the end of March last year.  But despite these below average conditions, the month was the unprecedented thirteenth in a row with above average temperatures. 

132013

With a high/low of 68°/51°, today's mean temperature was two degrees above average, just enough to move the month's mean temperature from 0.1 degree below average to right at the average.  Thus, it joined August 1999 and August 1985 as the only months since 1980 to have a mean temperature on par with the monthly average.  April's high was 0.1 above average; the low was 0.1 below average.  However, what was far from average was the month's precipitation, which amounted to just 1.31".  This was 71% below the norm of 4.51", making it the fifth driest April on record (and the driest in 50 years).

2014

Until this year, April 30 was one of three dates that had never seen an inch of rain.  That distinction ended today as nearly five inches flooded the area, with more than half of it falling after 6 PM.  The 4.97" that fell was the ninth greatest daily rainfall on record.  Besides the rain it was also a very raw day, with temperatures only in the 40s.

2019

Today was the eighteenth day this month with measurable precipitation, the most of any month since May 2012, and the most on record of any April (the most of any month is nineteen days, in Dec. 1972 and May 1973).  However, despite this high frequency of rainy days, the amount of rain that fell in April, 4.55", was just an average amount.  (Seven days had 0.03" or less.)  By contrast, New York's ten rainiest Aprils averaged 12 days of precipitation (ranging from nine to fifteen).

this is the only day in April never to have any measurable, or even a trace of snowfall.

2019 - 0.04" of rain fell just before sunrise today, bringing the month's total to 4.55". with last April having 5.78" of rain, this was the first time consecutive Aprils had 4"+ of rain since 2004-2007. this was the eighteenth day this month with measurable rain, most of which was after 4/12. this set a new April record, besting 1874, 1934 and 1957 by two days. the last time any month had as many such days as this month was in May 2012.

William

2019's rain made this the sixth day in a row with some (totaling to 1.18" during these days). this was the first time any April has ended with six days of measurable rain. April 2018 came close however, with its streak occurring from 4/24 to 4/29 (1.33" fell during those days).

What is interesting about 1940 and 2020 being the only Aprils since 1900 to lack a 70+ degree high is in the 1800s there were 4 Aprils in a row like that (1873-1876).

William

somewhat similar to 2012, the final sixteen days of April 2020 all had colder than normal temps. when was the last time (if there was a last time) any calendar month ended with at least sixteen days of colder than normal temps?
