The detailed forecast also says slight to blowing dust is expected in some inshore areas at times along with scattered clouds, while visibility may drop to 3km or less. It will also be cold by night.

The Met department recently reported that a significant drop in temperature was expected in the country this week after a slight increase during the weekend. The mercury level may drop to 11C in Doha and below 5C in the southern parts of the country during this period, it said.
According to the forecast, the country will be affected by northwesterly fresh to strong winds until Monday due to the extension of a Siberian high-pressure system over the region, causing a noticeable drop in the temperature.
Wintry cold weather is expected to prevail in the country, especially at night, until the end of this week. The temperature in Doha is likely to range between 21C and 11C at night, while the minimum in the southern areas may drop below 5C, the report states.
As the sea condition is also likely to be rough, the Met department has urged people to be cautious and avoid venturing into the sea during this period in the view of the expected conditions.
The minimum temperature Sunday is likely to be 12C in Dukhan and Al Khor, 13C in Wakrah, Mesaieed and Abu Samra, 15C in Ruwais and 16C in Doha. On Saturday, the minimum was 12C in Dukhan, Karana and Shehaimiya, while in Doha it was 16C. The maximum went up to 30C in the Qatar University area and 29C in Doha, but it is expected to drop sharply Sunday.
Strong winds are expected in most areas along with poor visibility in some places due to dust, the Qatar Met department has said.
