Heavy thunderstorms have hit the mountainous regions of UAE and Oman in addition to interior UAE. With the upper low still in place over SW Asia, confluent and rising air currents have developed into a chain of thunderstorms. The storms have generated dusty winds in the surrounding area, and also lowered temperature to 22c in Fujairah due to rain-cooled air. As much as 21mm of rain fell in Fujairah, with probably higher amounts in Hetta which received more thunderstorms.
As the last few days brought interesting afternoon thundershowers to interior and mountainous UAE along with the eastern coast, the same is expected to continue on Monday, Tuesday, and Wednesday along the Hajar mountains of the UAE and Oman. The weak upper low over SW Asia, although the first this season, is expected to reduce the impact of the upper high that usually suppresses convective thunderstorms. There will also be scaterred showers and thunderstorms over eastern half of Iran and afghanistan, marking the first rain of the season. Later this week a high pressure takes over again over the Arabian Peninsuala as [ Read More ]
During the period from Thursday Oct 6th to Saturday Oct 8th, there is small probability of some isolated thundershowers along the Hajar mountainous and over the UAE eastern coast along the Gulf of Oman. There will also be a small decrease in temperatures in the coming days across most areas of the UAE. Due to slight weakening of the subtropical high and slight cooling at lower levels, surface winds converging along the mountains should face less resistence to develop into isolated brief shower clouds. But October is typically a very dry month.
The first temperature drop is coming by the end of the first week of October. While temperatures are likely to stay very warm, there will be a noticable change in temperatures starting October 6th. There could be around 3 to 5 degrees celsius decrease in daytime temperature, compared to end of September. This change will be accross the UAE and other Gulf countries, where daytime temperature will hover around mid 30s. Even inland areas will experience this change as temperatures will struggle to hit the 40c mark. Nights, if not humid, should also be more bearable. This marks the first, out [ Read More ]
