In the years since 1970 the average date for the first frost in Central Park has been Nov. 18. (In the 1970s the date was Nov. 7; since 1980 this reading has occurred two weeks later, on Nov. 21). It's occurred as early as Oct. 15 (in 1875) and as late as Dec. 22 (in 1998).
Today's high of 63° would be the last day with a reading of 60° or milder for four-and-a-half months, until 4/1 (when the high reached 70°).
The 0.05" of rain that fell today was the last measurable precipitation of the month. In total, just 0.71" fell, tying Nov. 1890 as the driest November on record (they've since fallen to third). This followed a dry October and September in which just 1.38" and 1.91" of rain fell, respectively. The four inches of rain that was measured made this the driest fall on record (and the following year would be the second driest). The next measurable precipitation would fall two-and-a-half weeks from now (on 12/6).
Yesterday and today were 21 degrees colder than average, with highs/lows that would be quite cold even by mid-winter standards: 30°/19° yesterday, and 33°/19° today. (The typical date for the first low of 32° or colder is mid-November, and the first high of 32° or colder typically occurs in mid-December.) Tomorrow would see a slight moderation in temperatures, to 37°/21°.
Today's high/low of 33°/21° made this the coldest day of the month (19 degrees below average). It would be five weeks before there was a colder day.
This was the fourth day since Nov. 7 to receive more than an inch of rain: 1.38" fell on 11/7; 1.22" on 11/10; 1.27" on 11/12; and 1.09" today.
Today was the sixth day in a row with temperatures 10 degrees or more below average. The high/low during these days was a chilly 41°/30°, twelve degrees colder than what's typical for mid-November. By coincidence, last November had a similar six-day stretch of very chilly weather (11/11-16).
The morning low of 36° was the chilliest reading of the month (along with Nov. 5). This was the first year since 1988 that November's coldest reading was warmer than October's (33° on 10/29 and 10/30). This was also the third year in a row in which November had no reading of 32° or colder. This November's coldest reading joined Nov. 1998 as the mildest chilliest reading reported in November.
This was the tenth year in a row in which no precipitation fell on this date.
Although 0.25" of rain fell overnight (most of it after midnight) the total rainfall since Sept. 23 remained below one inch, a span of 57 days - the third longest dry streak since 1950 (longest was 61 days in 1964; second longest was 58 days in 1999). This was the first time in eleven years that rain fell on this date.
After flirting with it the past few days, the temperature fell to 32° for the first time this autumn. It came after the passage of an Arctic front that brought unseasonably cold air to much of the continental US. And though the day's high temperature was officially 45° just after midnight, afternoon temperatures were in the low 30s, with wind chills in the teens.
Today's unseasonably cold high/low of 36°/30° (14 degrees below average) was half as warm as it was a week ago, when the high/low was a balmy 72°/64° on 11/11 (19 degrees above average). Today's low was also the coldest reading of the month (and repeated tomorrow).
