Today in New York Weather History: October 20

 

1905

Six of the past seven days had highs in the 70s (warmest reading was 77°) at a time of year when the average high is in the low 60s.  And four of the days had lows in the 60s (warmest was 68° on the 19th, a record that still stands).  Cooler air moved in later today after a coastal storm that produced 2.33" of rain between last night and noon today exited.

1927

The 0.12" of rain that fell this afternoon brought the total rainfall since 10/3 to nine inches.  During this eighteen-day period there were four nor'easters, each which dumped more than an inch of rain: 1.60" on 10/3-4; 1.44" on 10/8-9; 2.04" on 10/12-13; and 3.80" on 10/17-19.

1972

This morning's low of 32° was one of the earliest freezing temperatures on record in Central Park and came a month earlier than the typical date for the first such frosty reading.  (The earliest frost on record occurred in 1876 on 10/15.)

1974

This morning's low was 31°, breaking the record set just two years earlier.  This was the third earliest date for a temperature of freezing or colder. 

1977

The afternoon high reached 58° for the third day in a row.  (However, each day had a different low.)

1989

2.78" of wind-swept rain fell today, and 5.34" fell over the past four days.  With today's rainfall (a record for the date), Central Park's total precipitation for the year topped 60 inches, making 1989 one of the five wettest years on record - with more than two months remaining in the year.  (Average annual rainfall is about 46 inches.)  Today's winds gusted to 40 mph.

2005

This morning's low of 49° was the first reading in the 40s of the fall, the latest date on record for this occurrence.  (The previous latest date was 10/16, which occurred in 1995 and 1955, later joined by 2017; then in 2021, the first low in the 40s occurred on 10/18.)  The first autumn low in the 40s typically occurs by the end of September.

2017

Humidity levels dropped below 20% during the first half of the afternoon, a rarity in October, which is the month least likely to experience humidity below 25%.

2018

Light showers in the pre-dawn hours amounted to 0.06", bringing the year's precipitation to 50.05" - just the seventh year (since 1869) with 50 inches or more thru 10/20 (later joined by 2021).
