A new polar air raid advances from the northern tip of the continent and threatens to install one again Frozen scene over much of the United States. After a first wave that already left extreme thermal traces and significant snow accumulations, meteorologists expect another wave to occur in the North American country Another week marked by freezing temperatures, storms and strong winds.
According to specialists AccuWeatherthe atmosphere has been rearranged since the end of November due to the Weakening of the polar vortexa vast low-pressure circulation that normally concentrates the coldest air in the hemisphere in the Arctic.
Modification of this pattern is permitted Extremely cold masses will initially descend to the center of the North American country and in the last days, in the East. This trend will continue.
This was explained by long-term meteorologist Paul Pastelok “He Polar vortex “He has been in a weakened and tense condition since the end of November.”a phenomenon that has caused Arctic air to advance towards the center and east of the North American country in recent days. “Maybe this will continue for a few more weeks.”he warned.
This is what the forecasts indicate Another polar air front will descend from the northern Plains on Thursdaywhile it will cross the border on Friday Midwest, will be reached by Saturday East Coast.
This sequence is entered after a Clipper system during the week will leave more snow in the states northern plainsHe Midwest and the inside of northeast.
Pastelok explained this “Two to three more bouts of intense cold” could develop between December 10th and 19th. He even brought up the possibility A frost affects the Central Florida towards the end of next week.
For long nights and weak sunlight, Temperatures will fall quickly and remain low for extended periods. Each outbreak will potentially be more severe than the last, especially in areas that have recently received snow.
AccuWeather predicted that in the next few days large parts of the north and northeast will face temperatures between 10°F (-12°C) and 19°F (-7°C).. During high winds, the estimated wind chill may be between 10°F and 20°F lower than the actual temperature increases the risk of frostbite for those who stay outside.
Even Significant cold snaps could occur in the southeastern United States in this new phase of the winter pattern.
When polar air from Canada enters again, the order of the clipper systems this will be a tour of the Midwest and Northeast with snow, short rains and strong windsas reported Fox weather.
From mid-week the effects will be noticeable on:
The forecasts of Fox weather warned that the second clipper ship will strengthen over the northern plains Gusts that may exceed 65 miles per hour (105 km/h). In North Dakota, Montana, Nebraska and Wyoming. In this context, strong winds were warned.
