"Arctic Blast" and generalized snow predicted for next month - here is where
February could see a rehearsal of freezing temperatures and powder that started in 2024.
Kick -off until 2024 recalled how serious winter time can be. From freezing temperatures has devastating floods , few regions have been spared since the beginning of January. But with several weeks before the start of spring, meteorologists have already predicted that there could be another "Arctic explosion" and more widespread snow next month. Read the rest to see why the conditions could become so extreme and where it could affect the most.

The "polar vortex" has already affected the weather this winter.
The icy temperatures that swept the country earlier this month were a reminder to shake that winter had arrived. However, colder conditions that usual were in fact the result of A bad weather Known as "polar vortex".
The term refers to an air flow in the antihorarous sense which maintains a block of Low pressure and cold air To the poles of the planet in place, according to the National Weather Service (NWS) of the National Oceanic and Atmospheric Administration (NOAA). Sometimes he goes down to the continental United States - and meteorologists say that this explains why so many regions have woken up freezing conditions Earlier this month.
"It seems that the warming of the minor [vortex] during the first week of January and the subsequent destruction of the polar vortex in the lower stratosphere were sufficient to at least help prepare the ground for the cold air epidemic on the 'North America last weekend, "Climate.gov wrote.

Experts warn another cycle could start which brings another explosion of cold and snow next month.
Even if the cold shots last week have reversed the course in some Métreme du Chaude Sanse , it is unlikely that we have seen the last Winter Arctic Blast . According to a blog article from Judah Cohen , atmospheric scientist and director of seasonal forecasts for atmospheric and environmental research (AES), the polar vortex is a "rapid transition situation" which "will come down to" rinse, foam, repeat ".

Cohen explained his reasoning during an interview with Fox Weather on January 23, where he also explained how he believed that the The forecasts take place in the next weeks. However, the next cold wave could start with the opposite time you might expect.
"For the first half of January, this polar vortex fell and fell in fault, moved south. We had the Arctic epidemic," Cohen told the network. "But now it's, it's back together, let's say, and it is a very tight rotation, the rotation of the polar vortex. All the cold air decreases to the North Pole, and we are going to have a more end sweet in January. "

A warmer weather could affect the atmosphere and bring colder temperatures in early February.
However, the growing mercury could end up being a red herring for what will happen.
"We are probably going to see a warm record, as we did in December," Cohen told Fox Weather in his short -term prediction. "But I then think that, often, when you have these Canadian warming, the polar vortex tends to move to a very large disturbance called sudden stratospheric warming or a stretching event, like an elastic (drawing cold air south)."
Cohen told the network that these very conditions were what created the freezing conditions of this month, and he thinks that there is "good luck" that he will repeat himself next month.
"I think that within the second week of February and perhaps even in mid-February, a stretched polar vortex becomes more likely," he told Fox Weather. "This should help put an end to the very soft model in place through North America. The intensity and duration of the cold associated with the stretched polar vortex must still be determined."
Changes in another natural phenomenon could also cause more snow.
Facing another explosion of freezing temperatures can be equal to the course of winter. But Cohen also says that certain regions could see more snow and that extreme weather conditions are headed for them because another variable affects the conditions.
Weather forecasts always consider the Effects of El Niño In winter, which describes a warmer plot of water than the average off the coast of South America. As a general rule, it generates a wealthy weather in the west while providing softer and less snowy conditions on the east coast, according to National Geographic . But as the season progresses, the weakening of heat could cause a radical change above the polar vortex.
"Regarding El Niño, I think that less than strong is better for snow and cold in the East," said Cohen The Washington Post in an email.
In total, Cohen thinks that those who hope for an early beginning of spring will probably be disappointed with what will probably happen. "I don't think it's the end of winter," he told Fox Weather. "I think it is not a ventilation of the model, but I think that a relaxing model."
