There are several reasons why Wednesday / Thursday nights are heavily snowed in the various mountainous heights

ArabiaWeather - Eng. Nasser Haddad - The Kingdom is expected to cross a new, highly effective air front, in the afternoon and evening of Wednesday, February 17, 2021, and will continue on Thursday morning, bringing with it the snowy and stormy weather, God willing, over most of the mountain heights that are more than 800 meters above sea level.

According to expectations, in addition to the huge clouds in the Mediterranean Sea off the coasts of the Levant and Egypt, it is expected that the Kingdom will be exposed tonight to a snowy atmosphere par excellence, after God’s will, especially over mountain heights that are more than 800 meters above sea level, as it is expected that opportunities will begin Snow in the central region improved with the afternoon hours, to regularize and intensify precipitation with the early evening hours and extend better to parts of the southern highlands, especially Karak and Tafila, provided that the peak period continues until dawn and Thursday morning.

There are several reasons why Wednesday / Thursday nights are densely snowy in the various mountainous heights

Huge clouds of clouds in the eastern basin of the Mediterranean Sea

The depression, classified as fourth-degree in the Arab Weather Scale, is accompanied by huge bundles of cumulus clouds loaded with rain and snow, and satellite images have also been observed, and this reflects the size and abundance of precipitation expected, God willing, if they begin to affect the central and later southern regions.

The intensity of thunderstorms off the coast of the Levant and Egypt

In meteorology, the strength of thunderstorms indicates the height and strength of atmospheric turbulence, and in our case this is expected tonight, the reason for this is due to the passage of very cold polar air in all atmospheric layers over the waters of the Eastern Mediterranean, which are considered to be very warm, as the temperature difference between the surface of Sea and high layers of the atmosphere to more than 40 degrees Celsius, and this means the explosion of cumulus clouds.

It went deep into the center of the depression and saturated it with large quantities of water vapor

The decrease in surface pressure in the center of the current depression is related to the increase in the quantities of water vapor in the atmosphere and the currents of the load rising from the bottom to the upper atmosphere, and as the moist air is less weight and dense than the dry air, this means a decrease in the surface pressure values.

The reason for the great saturation of moisture and water vapor in the stormy air system accompanying the depression is due to the rush of very warm and humid tropical wet currents from subtropical regions of the African continent to Iraq, Turkey and finally to the island of Cyprus, where it gives a great increase in the momentum of the expected weather.

The above can be summarized by the presence of huge thunderstorms revolving around the center of the depression on the island of Cyprus, and the severity of the coldness of the polar air rushing towards the Kingdom, to expect that the kingdom's heights will be affected, God willing, by dense snowy atmospheres sometimes, leading to accumulations clearly, the higher the height above the surface the sea.
