Arab Weather - The latest outputs from the American GFS numerical model show indications that Saudi Arabia will be affected by a rainy and toxic condition during the last third of the month, resulting from the influx of tropical moisture coming from the Arabian Sea. Initial analyses indicate that this moisture mass may lead to a return to intense thunderstorms and an expansion of their impact, with its focus on the southwestern sector of the Kingdom.

 

Thunderstorm forecast

According to model updates, thunderstorms are expected to be accompanied by showers of varying intensity, which may be heavy at times, accompanied by local hail in some areas. Cumulonimbus clouds are also expected to form quickly and spread over wider areas depending on moisture activity and surface and upper wind currents.

 

Why does the US model indicate this rainy condition?

Analysis indicates that the American model indicates this rainy condition is a result of tropical moisture flowing from the Arabian Sea, resulting from a tropical condition in the Arabian Sea, which the same numerical model indicates in the last third of the month, God willing.
