Jordan | A new, third-degree weather depression will affect the north of the Kingdom on Thursday, bringing heavy rain during the day, and will later move to the central region and then parts of the south.

Arab Weather - The latest outputs of computer simulation maps indicate that the Kingdom will gradually be affected, starting from the morning hours of Thursday, January 1, 2026, by a third-degree (moderate-high effectiveness) low-pressure system, which is the third low-pressure system to affect the Kingdom during this week.

Summary and classification of low-pressure systems:

• Level: Third (Medium to High Effectiveness)
• Period of actual impact: approximately 36 hours, from Thursday morning until Friday afternoon
• Expected rainfall amounts: 20 to 80 mm
• Wind gusts: 70 km/h and may exceed that locally, especially in the southern highlands of the Kingdom, leading to dust storms in the eastern desert.
• Temperatures: 2-8 degrees Celsius.
• Snow: Unexpected

Timeline of the third-degree low-pressure system:

Thursday morning: A cold front will cross the north of the Kingdom in the morning, accompanied by heavy rain.

Accordingly, on Thursday morning, a cold front is expected to cross the northern regions of the Kingdom, resulting in generally cloudy weather and heavy rainfall across the northern regions, leading to significant flooding of valleys and torrents. Gradually, during the day, wind speeds will increase in most areas of the Kingdom, and most regions will be temporarily spared from rainfall (except for the north of the Kingdom and some central parts).

Thursday evening and night/Friday: A highly effective cold front arrives in the central region, bringing widespread rainfall.

As evening and night approach, the low-pressure system intensifies. A highly active, slow-moving cold front will reach the central regions after completing its passage through the northern region, bringing rainfall to Amman, Balqa, and parts of Zarqa and Madaba governorates. This rainfall is expected to extend to Karak governorate by midnight Thursday/Friday, becoming heavy at times. Given the saturation of the soil and ground with moisture and the heavy rainfall experienced over several days during the past week, the following is expected:

• Very large flow of valleys and reefs
• Flash floods and torrential rains, including in the northern and central Jordan Valley regions
• Large water pools on the roads
• Potential for soil and rock erosion

Friday: The low-pressure system moved away from the Kingdom, bringing very cold weather.

During the remainder of Friday, the low pressure system will gradually move away from the Kingdom, but cold and humid air currents will continue to affect the region, and temperatures will remain about 3-4 degrees Celsius below average. Cold weather will prevail in general, with clouds appearing at different altitudes, and there will be occasional chances of rain in parts of the north and center of the Kingdom and some southern highlands.

Friday night/Saturday morning: The Siberian high-pressure system begins to affect the region, bringing frost to several areas.

God willing, the Kingdom is expected to begin being affected by the Siberian high pressure system during the night hours, resulting in a noticeable drop in nighttime temperatures and very cold weather in most areas, with frost expected at night in several regions.

Due to the effects of the low-pressure system, Arab Weather recommends the following:

• Wear warm clothes, especially during the night and early morning hours.
• Ensure the safe use of heating appliances.
• Drive carefully and leave a safe distance during rain and fog.
• Be aware of the risk of flash floods and overflowing valleys, especially in low-lying areas and locations where flash floods usually form.
• Beware of landslides and rockfalls, especially in the southern highlands, slope areas, and valleys.
• Be aware of dense fog and reduced horizontal visibility on highways.
