When winter rolls around, I am often reminded of the old Scandinavian saying: “There is no such thing as bad weather, only inappropriate clothing.”
Since the weather is going to do whatever it is going to do, we all need to be aware of our environment and prepare for what Mother Nature throws our way. In winter, that means cold temperatures.
Extreme cold causes the body to lose heat faster than it can be generated. Prolonged exposure, according to the CDC, can cause serious health problems such as hypothermia and frostbite.
To stay safe this winter, remember to bundle up in layers and wear hats and gloves to minimize the loss of body heat.
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!

New York City, along with much of the northeastern US, is suffering from weather whiplash this week.
Last Wednesday, the temperature in Central Park soared to 85°F, setting a new record high for the date. This Wednesday, the mercury only made it to 51°F. That is a difference of 34°F! Our normal high for this time of year is 60°F.
Overnight lows in the city have also seen a dramatic decline. Dropping to 38°F early this morning, it was the coldest reading the Big Apple has seen since last April.
After enjoying summer-like conditions just a few days ago, these brisk temperatures are a reminder, albeit a jarring one, that autumn is a transitional season and winter is not too far off.
Ushered in by a dip in the jet stream, these chilly conditions are not expected to last much longer. Temperatures are forecast to rebound to more seasonable levels by the weekend.

The calendar says mid-May, but it felt more like March in New York City this weekend.
After a warm spring day on Saturday with readings in the 70s, a cold front swept through the region ushering in significantly cooler conditions. The high on Sunday only reached 57°F, which is 13°F below average. This dramatic cool down was also accompanied by strong winds with gusts in excess of 40-mph.
Moving from Sunday into Monday, the over-night low in Central Park fell to a chilly 43°F. That is the coolest May temperature the city has seen in three years. It was also just one degree shy of tying the record low of 42°F set in 1878. Our normal low temperature for this time of year is 54°F.
With Memorial Day – the un-official start of summer – just two weeks away, many New Yorkers will be happy to hear that temperatures are expected to rebound to more seasonable levels later this week.
With unseasonably warm temperatures causing trees and flowers to bloom early across New York City, it has felt like spring here for more than a few weeks. But now, as April begins, winter has come fighting back for an encore performance.
The high temperature in Central Park on Friday was a balmy 79°F. Today, it was only 45°F and even colder conditions are expected as the week goes on. So, what’s causing this dramatic cool down? The answer lies in the changeable pattern of the jet stream.
A persistent area of high pressure had been sitting off the eastern seaboard recently, creating a ridge in the jet stream and blocking any cold air from moving southward. Now, the pattern has shifted and a trough in the jet stream is allowing cold air to spill out of Canada and across the northeast.
The first wave of chilly air moved through on Sunday and caused powerful winds to whip through the area. The NWS reported winds gusts of 45 mph in Central Park and 64 mph at JFK airport.
Another wave of arctic air is expected tonight. With the temperature projected to plummet into the 20’s, the NWS has issued a freeze warning for the city and surrounding area – bad news for all the early blooming plants and trees. The forecast high for Tuesday is only 39°F. The city’s normal high for this time of year is 57°F and the normal low is 41°F.
As spring is a transitional season, temperature swings between warm and cold are not uncommon. But, after the city’s second warmest winter and fourth warmest March on record, many folks are finding this spring cold snap more than bit jarring.
An arctic blast sent NYC into a deep freeze this weekend. With temperatures dipping below 0°F on Sunday, it was the city’s coldest Valentine’s Day in one-hundred years!
According to the NWS, the temperature in Central Park fell to -1°F early Sunday morning. That is a staggering 30°F below average and shattered the previous record of 2°F set in 1916. It was also the first time the city’s temperature dipped below 0°F in 22 years. The high only made it to a frigid 15°F, a new record minimum maximum temperature for the date. When factoring in the wind chill, it felt as cold as -20°F. Our normal high for this time of year is 41°F and our normal low is 29°F.
As cold as it was on Sunday, it was not the coldest day the Big Apple has ever experienced. That dubious honor belongs to February 9, 1934, when the temperature fell to a brutal -15°F.
A weakened Polar Vortex and deep dip in the jet stream drove this weekend’s record cold conditions. But, temperatures are expected to rebound to above average levels by Tuesday. So, it seems this winter’s weather rollercoaster will continue moving forward.

After a delayed start, winter is off and running in the northeastern US. An arctic outbreak has sent the region into a deep freeze with many cities dealing with the coldest temperatures they have seen all season.
Here in New York City, the mercury fell to 11°F in Central Park this morning – the coldest reading the city has seen since February of last year. The high only made it to 29°F. While this type of cold pattern is not that uncommon in January, it feels rather jarring after a record warm December. The city’s normal high for this time of year is 38°F and the normal low is 27°F.
Produced by a deep dip in the jet stream, these current frigid conditions are not expected to last much longer. But, after a brief warm-up, another shot of arctic air is forecast to hit the city next week. Keep those coats and gloves handy!
March 2015 was a bit of a weather rollercoaster in New York City. We had highs ranging from a chilly 27°F to a relatively balmy 62°F. In the end though, with 23 out of 31 days posting below average readings, the cold won out. The extended cold snaps helped lower the city’s mean temperature for the month to 38.1°F, which is 4.4°F below normal. That makes March 2015 the coldest March the city has seen in 31 years.
In terms of precipitation, March 2015 was unusually snowy. In fact, according to the National Weather Service, it was NYC’s 6th snowiest March on record. The city measured 18.6 inches of snow in Central Park, which is a staggering 14.7 inches above average. We even had snow falling on the first day of spring.
Rainfall was also abundant. The city received 4.72 inches, which is 0.36 inches above average for the month.

For the second year in a row, New York City had an unusually cold and snowy winter. While last year saw the term polar vortex go viral, this winter was actually colder in the Big Apple.
The city’s average temperature for this past meteorological winter (December, January, and February) was 31.4°F. That is 3.7°F below normal and 1.6°F below last winter’s average. This winter, December posted an above average reading, but both January and February were significantly colder than normal. In fact, February 2015 was the city’s 3rd coldest February on record.
In terms of snowfall, every month this winter, with the exception of December, was an overachiever. January brought the city 16.9 inches of snow, February produced 13.6 inches, and March delivered a whopping 18.6 inches. All together, the city saw 49.1 inches of snow in Central Park. On average, NYC typically gets 25.8 inches for the entire winter season.
February was frigid in New York City this year! With an average monthly temperature of 23.9°F, it was the city’s 3rd coldest February on record.
We experienced several arctic outbreaks that caused fountains to freeze and ice to form on both the Hudson and East Rivers. Overall, we had 15 out of 28 days where our high temperature did not get above freezing. We also had 7 days where our low temperature dropped into the single digits, including February 20th when the mercury plummeted to 2°F in Central Park, marking a new record low for the date. Our normal high for the month is 42°F and our normal low is 29°F.
These relentlessly cold conditions were produced by an almost continuous deep dip in the jet stream that allowed arctic air to dive south into our region. Some scientists suggest there may be a connection between these extended periods of extreme cold and climate change. They say as the Arctic warms, the jet stream slows down creating a wavier configuration that allows weather systems to stay in place longer.
In terms of precipitation, February is usually a snowy month in the Big Apple and this year was no exception. The city had 13.6 inches accumulate in Central Park, which is 4.4 inches above average. The month did not bring us a single blockbuster snow event, but rather a string of small storms. Rainfall, on the other hand, was lacking. The city only received 2.04 inches, which is 1.05 inches below normal for the month.
