WASM – The Kingdom will be affected by a long and cold series of several atmospheric depressions accompanied by very large quantities of rainfall and extremely cold weather conditions, which are expected to begin Monday night and continue until the end of the first week of February at the earliest.
The atmospheric depressions coincide with an extremely cold polar air mass, where the WASM Regional Center expects a winter storm to form at the end of the week in the eastern Mediterranean region, resulting in stormy winds, very large quantities of rainfall, extremely cold weather, and snowfall on high mountains at a later time.
The polar air will gradually deepen during the impact of the winter storm, beginning and mid-next week, and the chances of snowfall on mountainous areas increase during the last days of January and the beginning of February, with details to follow.
The WASM Regional Center issues this weather bulletin based on internally developed W.DMM technology and climate model data from the WASM Regional Center, which is unique in the Arab region. This type of weather bulletin is characterized by high accuracy, stability, and no significant changes to its details.
Heavy rainfall begins Monday night and continues until Friday morning in intervals|
Heavy rainfall will fall in intervals in the western regions of the Kingdom, which also include the highlands of the southwest of the country noticeably this time. Very large quantities of rainfall are expected during these days in many western regions, and this rainfall will sometimes be mixed with melting snow showers on the peaks of high southern mountains. Thunder is expected at times and hail is expected to fall during this period.
A winter storm begins Friday daytime and continues for several days|
As a result of a surge of an extremely cold polar-origin air mass towards the region, this causes the formation of a winter storm that will, God willing, be accompanied by very large quantities of rainfall and stormy winds with gusts exceeding 100 km/hour, snowfall on the peaks of high mountains, and temperatures approaching zero degrees Celsius in mountainous areas.
Due to temperatures being slightly higher relative to comprehensive snow conditions, it is not expected to result in a strong blizzard or comprehensive snow conditions, but rather snowfall is limited to high mountains during the beginning of the winter storm's impact. However, this is not all, as the WASM Regional Center continuously monitors the flow of extremely cold polar winds towards the region during the impact of this winter storm.
Deepening of polar winds in the last days of January and the beginning of February|
With the continuous temperature drop expected as a result of the continued flow of extremely cold polar winds towards the eastern Mediterranean basin, this increases the chances of snowfall in mountainous areas, and this at a later time from the beginning and mid-next week and the days that follow this period. Details will be issued as the time period approaches and the nature of the impact of these polar air masses.
"Very" large quantities of rainfall|
The expected atmospheric depressions and winter storms will be characterized by "very large and possibly record-breaking" quantities of rainfall that may exceed more than half of the entire seasonal rainfall average, as a result of the continuity of these storms and strong depressions, cold weather conditions, and large quantities of moisture surging from the Mediterranean Sea.
Scientific Analysis|
As a result of the high activity of Atlantic storms in the north-central Atlantic region and its northwestern parts and east of the United States, this has caused a strong rise in surface atmospheric pressure values over the European continent, which causes polar-origin air masses to be pushed towards the eastern Mediterranean basin, northern Arabia, and northern Egypt. These surges will continue for an extended period due to the continued presence of a strong atmospheric high over the European continent.
Looking at further periods, strong storms are expected to renew over the west, central, and south of the United States with the end of January and beginning of February, leading to the renewal of storms in the west and north Atlantic, which causes a repositioning of the European atmospheric high and with greater strength, resulting in the push of another North Atlantic polar air mass towards eastern and southeastern Europe. This places many regions of eastern Mediterranean basin countries, including Jordan, under the continued activity of polar conditions for a long period that may even exceed the first week of February. The WASM Regional Center will continue to issue all details regarding expected weather conditions during the coming period.
