New York has already had a winter taste, but without a clear trajectory. On December 14 an unexpected snowfall affected all five boroughs, imbiancando roads and parks and temporarily interrupting the city routine. Immediately afterwards, however, the temperatures collapsed rapidly, pushing the municipal administration to activate the “blue code”, the protocol that snaps when the cold represents a concrete risk for the most vulnerable people, especially those who live in the street.
A few days after Christmas, the weather picture remains unstable. Friday, December 19 is expected an abnormal rise of temperatures, with maximums around 56 degrees Fahrenheit (about 13 degrees Celsius), values close to the seasonal records for the city. The data is relevant because it arrives after days of fully winter weather and anticipates a new sudden change: in the evening, according to the forecasts, the mercury colony should quickly descend up to about 20 degrees Fahrenheit (less than 7 degrees Celsius), reporting conditions of frost within a few hours.
Thermal variability adds bad weather. Between the night of Thursday and the day of Friday there are intense rains, with possible water accumulations on the roadways and wind gusts that could reach the 50 mph (about 80 km/h). These phenomena, in New York, often lead to slowdowns in traffic and inconvenience in public transport, especially in the most exposed areas. It is a picture that confirms a trend already observed in recent years: weather episodes increasingly sudden and difficult to predict, even in the middle of the winter season.
