Weather of Arabia - Eng. Nasser Haddad - The kingdom is expected to be affected by two air depression this week, the first of which will extend between Sunday and Tuesday, and the second is expected to affect the kingdom on Thursday and Friday, God willing.

The chance of rain gradually extends to the eastern plains, the desert, and the southern mountainous highlands. Fog and clouds in contact with the surface of the earth are also expected to be formed over the high mountainous heights.

A closed air front (hybrid) that combines the characteristics of the cold front (occasional thunderstorm showers) and the warm front (continuous rain for long periods), and is accompanied by sometimes dense low clouds ( Nimbostratus ) interspersed with some thunderstorm.
On Monday, the rains continue at intervals, God willing, sometimes accompanied by thunder, so the Arab weather calls for attention from the formation of torrents and the flow of valleys due to the abundance of rain at times.
The impact of the depression is diminishing on Tuesday, with sporadic rain opportunities still present, especially in the north and center of the kingdom.
The weather stabilizes on Wednesday and temperatures tend to rise with the appearance of medium and high clouds in some areas, but this stability is temporary, due to an elevated air rush towards northern Arabia and the Levant, including the Kingdom.
