As winter approaches, temperatures in northern Bangladesh may start to gradually drop from the third week of the current month, according to Bangladesh Meteorological Department (BMD).

Several regions may also see rain or thundershowers, while light to moderate fog could appear over river basins.

"Rain or thunder showers accompanied by temporary gusty wind is likely to occur at a few places over Khulna, Barishal, and Chattogram divisions, and at one or two places in Rajshahi, Mymensingh, Dhaka, and Sylhet divisions," the BMD said.

Meanwhile, other parts of the country are expected to remain mostly dry with partly cloudy skies.

In addition to the rain forecast, light to moderate fog is likely to form over river basins during early morning hours, as presented by BMD.

Yesterday, the country's highest temperature reached 34.5°C in Feni, Sitakunda, Kutubdia, and Ambagan, while Tetulia recorded this morning's lowest at 18°C. In the 24 hours leading up to 6:00am today, Narayanganj received the highest rainfall at 36mm, with Dhaka recording 22mm.
