Why Jordan is on the verge of being affected by a low-pressure system?

Arab Weather - A low-pressure system is currently centered over the Black Sea, primarily affecting the northern Levant, particularly Syria and Lebanon. Heavy rains are expected to hit western Syria and several areas of Lebanon tonight and Thursday.

In contrast, the Kingdom lies on the outskirts of the low-pressure system, meaning its effects will be minor and limited in scope. Scattered showers are expected to fall on the northern regions of the Kingdom, and may extend locally to some central regions. Temperatures will remain cooler than average for this time of year.

What prevents the direct effects of the low pressure system from reaching Jordan?

Scientifically speaking, the low pressure system's weak direct impact on Jordan is due to the fact that the Kingdom lies beneath the dry portion of the jet stream, a fast-moving air current at high altitudes that prevents the upper air pressure system from deepening southward.

The low pressure system is located in the upper atmosphere (5,500 meters above sea level) over Turkish territory, a location far from the Kingdom, which places the latter on the southeastern edge of the low pressure system, i.e. in the area of less humid air currents.

The subtropical high pressure system centered over North Africa and the eastern Mediterranean, along with the weak high pressure system in southern Europe, are also factors preventing the depression from deepening southward. This is pushing the cold, humid air mass northward, keeping Jordan's atmosphere under the influence of dry air currents in the middle and upper layers.

And God knows best.
