Early warning - Saudi Arabia | As of Saturday.. a great intensification of the rainy situation and heavy thunderstorms in large areas..Details

Arab weather - Sinan Khalaf - Despite weather forecasts that clearly indicate that parts of the Kingdom of Saudi Arabia will begin to be affected by the first widespread spring rainy event, starting from Thursday, the intensity of weather fluctuations will increase remarkably and significantly starting from Saturday, God willing, and it will be carried with it. Thunderstorms in many areas.

Heavy thunderstorms in many areas from Saturday

The cold upper basin is deepening and strong April clouds are active again overhead

The outputs of the computer processing in the Arab Weather Center indicate expectations that the upper cold basin will deepen the Kingdom’s atmosphere on Saturday and Sunday 23 and 24 April 2022, coinciding with the blowing of warm and humid air currents from tropical shows, and the displacement of the subtropical air high from the atmosphere of the region, which leads to an expansion The intensification of unstable weather conditions in light of a superficial response to the Red Sea depression, clearly and effectively. This system works to raise the power of rain and intensify the intensity of thunder clouds on the mountainous heights and eastern slopes located in the west of the Kingdom, and the extension of rainy clouds to include large parts of the Kingdom, God willing.

It is expected that rains will be thundery and heavy at times in several parts of the Kingdom, especially in Hail, Al-Qassim and Medina, and it will be accompanied by showers of hail and thunderstorms, where the formation of water gatherings or torrents is not excluded, while the rains are less strong in the rest of the regions.

The weather forecast staff looks again with optimism for the coming period, as the numerical simulation of the atmosphere indicates that the opportunity is favorable for more weather conditions during the last week of this month, which may include new Gulf countries, God willing. It is not possible to deduce all the details from now on for that period, but that period is a promising period for improving the rainy reality, which suffers from great weakness.

Significant changes to the air systems for the benefit of the region

These expected atmospheric disturbances come due to a combination of a shallow drop in atmospheric pressure and a dynamic contribution to the vertical thermal difference and a superficial response as well as to the Red Sea depression effectively, which also works to excite warm and humid air currents from tropical latitudes. The presence of temperature differences of up to 30-35 degrees Celsius, and perhaps more, between the surface of the earth heated by solar radiation and the cold air located at the top is the first condition for the condensation of cumulus clouds, and the extent/quantities of water vapor extension towards the Kingdom’s atmosphere is an important condition as well. To ignite these thunderclouds, which is something that numerical models find very difficult to sense until now, so the computer modeling outputs still fluctuate around the intensity of the rainy condition.

Therefore, all of the above is considered within the context of the forecasts of the latest weather readings issued by the Arab Regional Center for Meteorology and Forecasting, so updates will be released that will highlight more details incrementally whenever needed, God willing.
