Arctic Blast Brings Record Cold to NYC

After getting off to a relatively slow start, winter has kicked into high gear. For the second time this month, a massive arctic outbreak has sent most of the eastern two-thirds of the U.S. into a deep freeze.

Here in New York City, the temperature peaked at just 16°F in Central Park on Thursday, tying the record cold high for the date set in 1935. The low dropped to 2°F, missing the record of -1°F by a few degrees. However, when you factor in the wind chill, it felt like a very memorable -17°F.

As cold as it was on Thursday, it was not the coldest day the Big Apple has ever experienced. That dubious honor, according to the NWS, belongs to February 9, 1934, when the air temperature reached a brutal low of -15°F.

The city’s normal high and low temperatures for this time of year are 39°F and 27°F, respectively.

This week’s unusually frigid conditions were the result of a deep dip in the jet stream and a lobe of the polar vortex reaching southward over much of the eastern part of the country. While a brief warm-up is expected over the next few days, it is still winter so keep those hats and gloves handy.

First Arctic Blast of 2019 Sends NYC into a Deep Freeze

After a relatively mild start to the season, winter’s chill has finally arrived in the northeastern United States. An arctic outbreak has sent the region into a deep freeze with many cities dealing with the coldest conditions they have seen since last January.

Here in New York City, the mercury fell to 4°F in Central Park on Monday morning and the high only made it to 14°F. While this type of cold shot is not that uncommon in January, it felt rather jarring after the temperature reached the mid-40s the day before.

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. After a brief warm-up, however, another shot of arctic air is forecast to hit the city next week. So, keep those coats and gloves handy!

Extremely Cold Weather Can Be A Danger to Your Health

An arctic blast is expected to sweep across the northeastern United States this week. With temperatures expected to fall into the single digits, it is important to remember that, like extreme heat, extreme cold can be very dangerous.

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, including hypothermia and frostbite.

Hypothermia is a condition of unusually low body temperature – generally below 95°F.  It impairs brain functions, limiting a victim’s ability to think and move.  Symptoms include severe shivering, drowsiness, confusion, slurred speech, and fumbling.  If left untreated, it can be fatal.

Frostbite is a localized injury to the skin and underlying tissues caused by freezing.  It can cause permanent damage and extreme cases often require amputation.  Areas of the body most often affected include the nose, ears, cheeks, fingers, and toes. Signs of frostbite include, numbness, skin discoloration (white or greyish-yellow), and unusually firm or waxy feeling skin.

While the symptoms of both hypothermia and frostbite can range in severity, victims generally require immediate re-warming and professional medical attention.

To stay safe in cold weather, the American Red Cross recommends:

There is No Such Thing as Bad Weather, Only Bad Clothing Choices

There is an old Scandinavian saying: “There is no such thing as bad weather, only bad clothing choices.” While it can be applied to any season, it seems most relevant in winter.

Since the weather is going to do whatever it is going to do, it is important to be prepared for anything that Mother Nature throws your 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.

Cold and Windy Conditions Expected for the Macy’s Thanksgiving Day Parade in NYC

The Macy’s Thanksgiving Day Parade is a long-standing holiday tradition in New York City.  For 92 years, it has marched rain or shine. Nevertheless, the weather has been a factor in 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 and injure 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 and the “Snoopy” and “Bugs Bunny” balloons had to be pulled from the parade because of damage from high winds.

This year, the wind could potentially be a problem again. Gusts are forecast to be between 20 and 30 mph during the parade hours. Temperatures are also expected to be a challenge. They are forecast to hover near record cold levels, with readings not getting out of the 20s. When the wind chill is factored  in, it will feel more like the single digits to low teens. This extreme cold will be more than a nuisance for holiday revelers, it will be dangerous. Frostbite is a real threat for anyone with exposed skin. So, bundle up if you are planning to be outside along the parade route.

Marching from West 77th Street to West 34th Street in Manhattan, the 92nd Annual Macy’s Thanksgiving Day Parade is scheduled to begin at 9 AM on Thursday morning.

Happy Thanksgiving!

April 2018: Unseasonably Cold and Wet in NYC

April felt like a wild ride of weather in New York City this year. It produced both a record-breaking snowfall and a balmy summer preview with temperatures in the 80s. However, with 19 out 30 days posting below average readings, the cold won out in the end. The city’s mean temperature for the month was 49.5°F, which is 3.6°F below normal.

While unseasonably chilly, the month was not a record breaker. That dubious honor, according the NWS, belongs to April 1874 when the monthly temperature was only 41.1°F. The city’s warmest April on record was April 2010 with a mean temperature of 57.9°F.

In terms of precipitation, this April was unusually wet with 14 out of 30 days producing rain or snow. In all, the city received 5.78 inches of rain, which is 1.28 inches above average. Of that total, 49% fell during a single heavy rain event on April 16. Snow was also abundant with 5.5 inches measured in Central Park. Coming down during a single storm on April 2, it set a new daily snowfall record for the date. On average, the city gets 0.6 inches of snow for the entire month.

NYC Sub-Freezing Cold Streak: Third Longest on Record

The extended cold wave that has been gripping New York City earned a place in the record books as it came to an end on Tuesday when the temperature climbed above freezing for the first time since Christmas.

In all, the city experienced fourteen consecutive days with temperatures below 32°F. That, according to the NWS, is the third longest sub-freezing cold streak ever recorded in Central Park. The coldest day came on January 6, when the mercury only made it to 13°F. The wind chill made it feel even colder.

These unusually frigid conditions were the result of a deep dip in the jet stream and a lobe of the polar vortex reaching southward over much of the eastern US. While a brief warm-up is expected over the next few days, it is still January so keep those hats and gloves handy.

NYC Monthly Summary: December 2017

December 2017 felt like another temperature roller coaster in New York City. Highs ranged from an unseasonably warm 61°F to a frigid 18°F. But with eighteen out of thirty-one days posting below average readings, including the second coldest New Year’s Eve on record, the chill won out in the end. The city’s mean temperature for the month was 35°F, which is 2.5°F below average.

On the precipitation side of things, the city received 2.21 inches of rain. That is 1.79 inches below normal. December is now the sixth month in a row to deliver below average rainfall in NYC. As a result, the latest report from the US Drought Monitor (12/28) now lists the city as “abnormally dry.” Snowfall, on the other hand, was abundant. The month produced four separate snow events, including the city’s first snowfall of the season. In all, 7.7 inches of snow was measured in Central Park. On average, the city gets 4.8 inches of snow in December.

New Year’s Eve 2017: Second Coldest on Record for NYC

New Year’s Eve 2017 was one for the record books in New York City.

The midnight temperature in Central Park was a mere 9°F, marking the city’s second coldest New Year’s Eve on record. The coldest was in 1917 when the temperature was only 1°F. The normal low for this time of year is 28°F.

These unusually frigid conditions are the result of a deep dip in the jet stream and a lobe of the polar vortex reaching southward over much of the eastern US. They are expected to remain in place for the near future.

Dressing for Cold Weather

When winter rolls around, I am often reminded of the old Scandinavian saying: “There is no such thing as bad weather, only bad clothing choices.”

Since the weather is going to do whatever it is going to do, it is important to be prepared for anything that Mother Nature throws your 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.
