Unsettled weather in UAE: Cooler weekend expected after rain with lows of 20°C

Dubai: Temperatures across the UAE are expected to fall further by the weekend, with overnight lows in coastal cities potentially reaching 20°C to 21°C. Daytime temperatures are also forecast to ease to around 30°C to 31°C, bringing cooler conditions across the country.

According to Ibrahim Al Jarwan, Chairman of the Emirates Astronomical Society, temperatures could drop more noticeably following the approaching spell of rain, with cooler weather expected towards the end of the week.

Speaking on the Direct Line programme on Dubai Radio, Al Jarwan said the developing weather system is among the first winter low-pressure systems arriving from the north during the current autumn season.

UAE Weather: First Winter Low-Pressure System Approaches

Al Jarwan explained that the approaching weather system is bringing changes in atmospheric conditions across the UAE, with increased cloud activity and a possibility of rainfall in several areas.

He also highlighted the upcoming start of winter according to the traditional local Al Duroor seasonal calendar.

Under this calendar, the first phase of winter is expected to begin between November 26 and 28. However, this is based on traditional seasonal calculations rather than the astronomical start of winter.

Moist Air Could Bring More Clouds and Rain

The changing weather conditions are not limited to clouds moving into the UAE from neighbouring countries.

According to Al Jarwan, a moist air mass accompanying the low-pressure system could encourage local cloud formation, particularly over mountainous areas.

These clouds may develop alongside the incoming weather system, increasing the possibility of rainfall and contributing to unsettled conditions across parts of the country.

Heavy Rain Possible in Mountainous and Inland Areas

Al Jarwan said the weather system could become stronger on Wednesday and Thursday, potentially bringing heavy rainfall to mountainous areas and some inland and western parts of the UAE.

The forecast also includes the possibility of:

Light rainfall in some areas.
Stronger winds, particularly during the afternoon.
Dust and blowing sand due to increased wind speeds.
Increased cloud formation over mountainous and inland regions.
The unsettled weather is associated with a surface low-pressure system accompanied by an upper-air low-pressure system.

NCM Forecasts Temperature Drop of Up to 6°C

The outlook is broadly in line with an earlier forecast from the National Centre of Meteorology (NCM), which indicated that the weather system would deepen from Wednesday and bring rainfall of varying intensity until Thursday afternoon.

NCM meteorologist Dr Ahmed Habib said temperatures could gradually decrease by around 4°C to 6°C over three days, followed by a further drop on Friday.

Although the main spell of unsettled weather is expected to ease by Thursday afternoon, some cloud activity could continue over the northern and eastern parts of the UAE on Friday.

With overnight temperatures potentially reaching 20°C to 21°C in coastal cities, residents can expect noticeably cooler conditions as the country moves towards the winter season.
