A direct polar air shower will bring heavy snow and cover hundreds of kilometres of western Europe at the end of the week.

<p style=";text-align:left;direction:ltr"><strong>Arab Weather -</strong> Weather experts at the Arab Weather Regional Center said that the latest outputs of advanced numerical computer models on air mass movements indicate a ripple in the polar jet stream, causing a huge polar air mass to rush in, extending hundreds of kilometers from the North Pole toward western Europe, and causing the development of several storms that bring heavy rainfall and snowfall.</p><p style=";text-align:left;direction:ltr"></p><h2 style=";text-align:left;direction:ltr"> <strong>The polar air mass covers an area of hundreds of kilometers and produces strong rainstorms.</strong></h2><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> In detail, a strong and huge high pressure system controls important areas of Greenland, causing a direct polar descent towards the west of the European continent in the form of a huge polar air mass extending for hundreds of kilometers. As a result of the thermal differences between the surface temperature of the Atlantic Ocean and the very cold air coming from the north, two rainstorms with low air pressure values are formed between Wednesday and the end of the week, bringing very heavy rain, strong winds and heavy snowfall.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> <a href="https://www.arabiaweather.com/ar/content/%D8%A3%D9%88%D9%84-%D8%B9%D8%A7... first storm over the Black Sea this year.
