Jordan: A second-degree (normal) low-pressure system will begin Monday evening, followed by a very cold air mass at the end of the week.

Arab Weather App - Weather experts at Arab Weather said that the Kingdom will be affected, God willing, starting from late Monday, December 15, 2025, by a new low-pressure system classified as a second-degree depression, followed by the flow of a very cold air mass, which will cause temperatures to drop to their coldest levels in months, as they will drop below 5 degrees Celsius in several regions of the Kingdom at the end of the week, God willing.

Details of the Kingdom being affected by a second-degree (normal rainy) low-pressure system starting Monday evening, December 15, 2025

God willing, temperatures are expected to drop on Monday, with generally cold weather and a tendency towards stability for most of the daytime, with clouds appearing at different altitudes. Winds will be light to moderate southwesterly.

During the evening and night of Monday/Tuesday, the Kingdom will be gradually affected by a second-degree low-pressure system, as cloud cover increases and the weather becomes unstable, ranging from partly cloudy to cloudy. There will be gradually opportunities for rain showers in several regions of the Kingdom. These showers may be heavy at times, especially in the southern regions, and may be accompanied by thunder, leading to the flow of valleys and streams and the formation of water accumulations in some areas. Low clouds will pass touching the ground, leading to the formation of fog and reduced horizontal visibility over the high mountain peaks.

And during the daytime hours of Tuesday, December 16, 2025, temperatures will drop further, with the maximum reaching around 10 degrees Celsius in the mountains, including the capital Amman. This will be several degrees Celsius colder than expected. The weather will be cold and partly to mostly cloudy, with showers expected in several areas of the Kingdom, God willing. Some of these showers may be heavy at times. Fog will continue to form over the mountain highlands as a result of low clouds passing near the ground. The winds will be moderate northwesterly with active gusts that will significantly increase the feeling of cold.

During Tuesday night/Wednesday morning, cloud cover will decrease, but there will still be a chance of rain showers, especially in the south and east of the Kingdom.

Computer simulation results indicate that the Kingdom will be increasingly affected by a very cold wind flow on Wednesday, December 17, 2025. This will result in noticeably cold weather during the day and very cold weather at night, with continued moisture in the atmosphere. The weather will be cold and partly cloudy, with a chance of some rain showers, especially in the south and east of the Kingdom. These showers may take the form of snow or light snow showers on the peaks of the Sharah Mountains. Hail showers may also occur in some other areas.

Details of the low-pressure system classification:

• Grade: Second (Regular)
• Rainfall amounts: 15-40 mm
• Wind speed: 50 km/h
• Areas: Most areas
• Duration of effect: 48 hours, from Monday evening until Wednesday evening
• Temperature: 3-9 degrees Celsius
• Snow: Snowfall in parts of Al-Sharah and the eastern desert

And God knows best.
