General forecast for the week

  • It is expected that the atmospheric height will deepen on the European continent, especially the western parts of it, with a complete receding of the influence of the semi-tropical atmospheric height on the Arabian Peninsula, which will give way to the extension of some cold upper air grooves sometimes from the north through Iraq and Iran, and at other times from the gateway to the Levant and the eastern basin of As a result, large parts of the Arabian Peninsula are affected by unstable weather conditions, which result in the multiplication of clouds and rainfall, God willing.
  • High chances of torrential rain in some areas.
  • Cooler weather during the hours of the night, dawn and early morning, so that it becomes less than its normal rates in large parts of the region.
  • Surface wind activity that provokes some dust and dirt.

God knows
