Jordan: The Kingdom will continue to be affected by complex weather systems (unstable weather conditions) at the beginning of next week.

Arab Weather App - Computer simulation results based on artificial intelligence indicate that the Kingdom will continue to be affected by what is known as complex weather conditions, which take the form of unstable weather conditions during the coming week, leading to thunderstorms in random areas of the Kingdom, and this means that the chances of flash floods will remain high.

Despite the positive indications of cold and humid air masses rushing into Jordan and the eastern Mediterranean basin next week, the method and axis of these masses' rush will determine the nature of their impact on the Kingdom. The first of these rushes is expected to occur at the beginning of next week (between December 6 and 7, 2025) and will cause a state of atmospheric instability and thundery showers of rain.

Indications of unstable weather conditions starting from the weekend

The same data via the Arab Weather application indicates expectations that the Kingdom will be affected by the extension of what is known as the Red Sea depression on Friday, where temperatures will rise and the weather will be partly cloudy, and the opportunity will gradually become available for scattered and local rain showers, God willing, in some areas, especially during the night hours.

On Saturday, the Kingdom will be increasingly affected by the extension of the Red Sea trough, which means that the extension of the Red Sea trough will coincide with the approach of a cold trough in the upper layers of the atmosphere, resulting in unstable weather conditions, especially during the evening hours and night of Saturday/Sunday, with showers of rain falling on random areas of the Kingdom, accompanied by thunderstorms.

Shortly after that, during the middle and end of next week, there is another surge of cold air, but this time in different layers of the atmosphere, leading to a significant and noticeable drop in temperatures. It is unclear how it will affect Jordan through a state of atmospheric instability or a winter low-pressure system, since most of these surges under such an atmospheric system do not usually produce a classified low-pressure system, although this is possible on some occasions. Therefore, it is advised to follow the updates issued by the Arab Weather application.

What do we mean by rainy conditions with complex characteristics?

The complex cases of atmospheric instability are essentially a surge of a low-pressure system in the upper atmosphere in conjunction with the extension of the Red Sea thermal low from the south in the lower atmosphere, with the availability of moist air currents in the atmosphere of tropical origin.

This interaction between different weather systems in the upper and lower layers of the atmosphere and the availability of tropical moisture leads to the emergence of unstable weather conditions, including rainfall of varying intensity and thunderstorms that cause flash floods in some areas, as happened in past cases. These cases cannot be described as classified low-pressure systems or even as having a winter character due to their lack of winter characteristics and their acquisition of an autumnal character (atmospheric instability and irregular thunderstorms in terms of time and place).

And God knows best.
