Early Spring Preview Brings Record Warmth to NYC

The calendar says January, but it felt more like early May in New York City this weekend.

In Central Park, the temperature soared to 69°F on Saturday and hit 68°F on Sunday, setting new record highs for both dates. According to the NWS, the previous records of 63°F for January 11 and 66°F for January 12 were set in 1975 and 2017, respectively.

It is also interesting to note that the overnight low temperatures for both dates (51°F and 43°F) were warmer than the normal high. The average high for the city in mid-January is 38°F and the average low is 27.

The primary driver of this unseasonable warmth was a large ridge in the jet stream. Sitting over the eastern part of the US, it allowed warm air from the south to flow further north than it normally would at this time of the year.

But, as with most things that go up, they must also come back down. The temperature is expected to moderate over the next few days but remain above average. More seasonable temperatures are expected to return by the end of the week. So, don’t put your winter coats away just yet.
