The return of the dreaded polar vortex is battering much of the eastern US this week, sending temperatures well into freezing territory and close to record lows – a phenomenon that could persist for much of the week leading up to Thanksgiving.
According to the New York Post, record-low temperatures are forecast for Friday and Saturday, with nighttime and early-morning mercury dipping into the 20s.
The temperature dropped into the 20s in some places in the northeast last night, and could sink as low as 21 degrees fahrenheit on Saturday, according to AccuWeather forecasts.
The record low for November 10 was 27 degrees in 1914. The high Saturday will be 37 to 43 degrees – up from the predawn low of about 24 degrees. The record low for November 11 was 29 degrees, set in 1933.
The forecast calls for 50 degrees on Monday, setting off eight straight days with high temps of at least 50, AccuWeather said.
The forecasting service added that signs are pointing toward a shift of the polar vortex that may cause snow, rain and other hazardous weather conditions like icy roads in some parts of the Northeast.
Right now, a cold snap is bringing an abrupt November reality check to most of the eastern US that will persist for the rest of the Veterans’ Day weekend. As Accuweather explains, the weather pattern will become even more interesting later in the week because it will feature a meteorological phenomenon called “the Greenland block”.
This pattern consists of relatively high pressure wind pattern near greenland that forces the polar jet stream to move sharply south toward the eastern US.
