Overnight temperatures in the UAE’s coastal cities could fall to 20°C or 21°C by the weekend, with daytime highs easing to around 30°C to 31°C, according to Ibrahim Al Jarwan, chairman of the Emirates Astronomical Society.

Speaking on the Direct Line programme at Dubai Radio, Al Jarwan said temperatures could drop more noticeably after UAE's approaching rainy spell, bringing cooler conditions towards the end of the week.

He described the weather system as one of the first winter low-pressure systems arriving from the north during the current autumn period. Al Jarwan also pointed to the approaching start of winter in the traditional local Al Duroor seasonal calendar.

According to this calendar, the first phase of winter will begin between November 26 and 28, he said. This refers to the local seasonal reckoning, rather than the astronomical start of winter.

The developing weather is not only about clouds moving into the UAE from neighbouring countries, Al Jarwan explained.

A moist air mass accompanying the system could also help clouds form locally, particularly over mountainous areas. These formations could develop alongside the incoming cloud cover, contributing to the unsettled conditions.

Al Jarwan said the weather system could deepen today and Thursday, bringing potentially heavy rain to mountainous areas and some inland and western locations.

He also mentioned a chance of light rain and stronger winds capable of raising dust, particularly during the afternoon, as the system begins affecting the country.

The unsettled conditions are linked to a surface low-pressure system accompanied by an upper-air low-pressure system, he explained.
