A Record Warm January Day in NYC

The calendar says January, but it felt more like April in New York City on Thursday. The temperature soared to 66°F in Central Park, setting a new record high for the date. The previous record of 64°F stood since 1890. The overnight low temperature of 47°F was also record warm.

The city’s normal high this time of year is 38°F, but a “January thaw” is not unusual. Nevertheless, after getting 6.3 inches of snow over the weekend and temperatures only reaching the mid-20s on Monday, these spring-like conditions felt like weather whiplash.

Many New Yorkers enjoyed the unseasonable warmth, while others were sad to see the snow melt away. It is, however, still January. So, regardless of opinions, keep your winter gear handy.

2016 Ties for 3rd Warmest Year on Record in NYC

New York City experienced some noteworthy weather in 2016, especially swinging between the extremes of record cold and record warmth. In the end, however, the warmth won out. The city’s average annual temperature in Central Park was 57.2°F, which is 2.2°F above normal. That means 2016 tied 1998 for NYC’s third warmest year on record!

With a strong El Niño in place at the beginning of the year, the city experienced its second warmest winter ever recorded. That said, a number of arctic outbreaks sent temperatures plummeting a few times throughout the season. The coldest day of the year came on February 14 when the temperature dropped to -1°F – a new record low for the date.

When summer rolled around, it brought the city a number of very hot and humid days. The city typically sees 15 days per year with temperatures in the 90s, but 2016 produced a sweltering 22. The hottest day came on August 13 when the mercury soared to 96°F in Central Park. When humidity was factored in, the heat index or real feel temperature was in the triple digits.

While El Niño gave readings a boost early in the year, it dissipated in spring and was replaced by its cooler sister, La Niña. Nonetheless, every month of 2016 posted an above average temperature in NYC.

Precipitation was also erratic. While there were a number of heavy rain events, including some that broke daily rainfall records such as the 2.22 inches that came down on November 29, the city was mostly dry. Overall, NYC received 42.17 inches of rain in Central Park for the entire year. That is 7.77 inches below normal. This dearth of rain caused moderate to severe drought conditions across the city.

Snowfall, ironically, was abundant. During one of the year’s arctic blasts, a large amount of moisture was also in place to produce a major show event. Dubbed the “Blizzard of 2016”, this one storm dumped 27.5 inches of snow on the city. It was the Big Apple’s biggest snowstorm on record. For the calendar year as a whole, the city accumulated 35.3 inches of snow, which is 9.5 inches above average.

Records for the Central Park Climate Station date back to 1873.

NYC Monthly Summary: December 2016

December felt like a weather roller coaster in New York City this year. We had highs that ranged from a cold 27°F to a relatively balmy 60°F. The warmth won out in the end, though. The city’s mean temperature for the month was 38.4°F, which is 0.9°F above our long-term norm. That makes December 2016 the Big Apple’s 18th consecutive month with an above average temperature – its longest streak on record.

In terms of precipitation, December was mostly dry. In all, we received 2.89 inches of rain, which is 1.11 inches below normal. Snowfall was also relatively scarce with Central Park reporting 3.2 inches for the month. The city usually receives 4.8 inches of snow in December. As a result of the this paltry precipitation, NYC remains in a moderate drought according the latest report (12/29) from the US Drought Monitor.

The Chances for a White Christmas

The Holiday Season is here and many people are dreaming of a White Christmas. The likelihood of seeing those dreams come true, however, are largely dependent on where you live.

According to NOAA, a White Christmas is defined as having at least one inch of snow on the ground on December 25th. In the US, the climatological probability of having snow for Christmas is greatest across the northern tier of the country. Moving south, average temperatures increase and the odds for snow steadily decreases.

Here in New York City, the historical chance of having a White Christmas is about 12%. This low probability is largely due to the city’s proximity to the Atlantic Ocean and its moderating influence on temperature. This year, despite some chilly conditions and accumulating snow earlier in the month, NYC is expecting above average temperatures on the big day.  So, the city’s already minimal chance for a White Christmas has largely melted away.

Snow or no snow, The Weather Gamut wishes you a very Happy Holiday!

First Snowfall of the Season in NYC

Let it snow! New York City saw its first measurable snowfall of the 2016-2017 winter season on Sunday with 0.4 inches reported in Central Park.

With the snow sticking only to grassy areas and parked cars, it was really just a dusting. But with holiday lights and decorations up all around the city, the softly falling flakes added to the festive atmosphere.

The timing of this first snowfall was about average for the Big Apple. Our earliest first snow event was on October 21,1952 and our latest was January 29,1973. On average, NYC gets 25.3 inches of snow for the entire winter season.

First Freeze of the Season for NYC

After a long hot summer and mostly mild autumn, winter has finally arrived in New York City.

According to the NWS, the temperature in Central Park dropped to 30°F late Friday night. That was the coldest air the city has seen since April and marks the first freeze of the season.

Compared to average, this first nip of frosty air arrived a bit late. The city usually sees its first freeze in mid-November.  The earliest 32°F reading on record came on October 19 twice, first in 1940 and then again in 1974.  Our latest first freeze was on December 22, 1998.

Produced by a deep dip in the jet stream, these current chilly conditions are expected to last through the weekend. Then, after a brief warm-up, another shot of arctic air is forecast to hit the city late next week. Keep those coats and gloves handy!

NYC Monthly Summary: November 2016

November felt like a weather roller coaster in New York City this year. We had highs that ranged from a relatively balmy 72°F to a chilly 41°F. However, with 19 out of 30 days posting above average readings, the warmth won out in the end. The city’s mean temperature for the month was 49.8°F, which is 2.1°F above our long-term norm. This was the Big Apple’s 17th consecutive month with an above average temperature – its longest streak on record.

In terms of precipitation, November was unusually wet and marked the first month since July that NYC received above average rainfall.  In all, we received 5.41 inches of rain which is 1.39 inches above normal. The majority of this plentiful total fell during two separate heavy rain events. In fact, November 29th was the city’s wettest day of the year and set a new daily rainfall record with 2.20 inches measured in Central Park. Nonetheless, despite these soakers, NYC remains in a moderate to severe drought according the latest report (12/1) from the US Drought Monitor.

Rainstorm Brings NYC its Wettest Day of the Year

A rainy day in New York City is typically nothing to write home about, but Tuesday’s precipitation was extreme. Heavy downpours brought the city more than half a month’s worth of rain in a single day.

According to the NWS, 2.2 inches of rain was measured in Central Park. Not only is that a new daily record for the date, it was the wettest day the city has seen so far this year. On average, we normally get 4.02 inches of rain for the entire month of November.

Suffering through moderate to severe drought conditions for several months, this rainstorm was largely beneficial for the area even if did put a damper on the Rockefeller Center Christmas Tree Lighting Ceremony. That said, even more rain is needed to bust this drought completely. Year to date, the city’s rainfall deficit is 7.24”.

This type of heavy rain event, according to NOAA, is expected to become more common in the northeast as global temperatures rise and precipitation patterns change.

Weather and the Macy’s Thanksgiving Day Parade

The Macy’s Thanksgiving Day Parade is a long-standing holiday tradition in New York City.  For 90 years, it has marched rain or shine. Nevertheless, the weather has been a factor for the event several times over the years.

Famous for its giant character balloons, high winds are the main weather challenge for the parade. According to city guidelines, the multi-story balloons cannot fly if there are sustained winds in excess of 23 mph or gusts higher than 34 mph. These regulations were put in place following a 1997 incident where gusty winds sent the “Cat in the Hat” balloon careening into a light post, which caused debris to fall on spectators.

The only time the balloons were grounded for the entire parade was in 1971 when torrential rain swept across the city. In 1989, a snowstorm brought the Big Apple a white Thanksgiving with 4.7 inches of snow measured in Central Park. The parade marched on that year, but without the “Snoopy” and “Bugs Bunny” balloons as they were damaged by high winds earlier that morning.

This year, the wind is not expected to be a problem. Temperatures, however, are forecast to be a bit chilly – mostly in the mid-40s.  So, bundle up if you are planning to watch the parade in person.

Marching from West 77th Street to West 34th Street in Manhattan, the 90th Annual Macy’s Thanksgiving Day Parade is scheduled to begin at 9 AM on Thursday morning.

Happy Thanksgiving!

NYC Election Day Weather

Weather does not subscribe to any political party, but it can play a major role on Election Day. Studies show that it strongly influences how many people head out to the polls, especially if poor conditions are forecast.

Here in New York City, the weather is picture perfect this year. With blue skies and temperatures in the 60s, voter turnout is expected to be high.

The exact date of Election Day varies every year, but it is always the Tuesday after the first Monday of November. Below are some interesting local weather facts about the big day.
