Rains and thundershowers are expected in Chittagong, Sylhet, Mymensingh and some other parts of the country, including Dhaka division, from Thursday, Dr Abdul Kalam Mollik, a meteorologist at the BMD, told UNB on Monday. 
The temperature will come down due to rainfall, he said.

A mild to moderate heatwave is sweeping over Barisal division, parts of Dhaka, Rajshahi and Rangpur divisions and Mymensingh, Moulvibazar, Rangamati, Chandpur, Noakhali, Feni and Bandarban districts,” reads a BMD bulletin.

The weather may remain mainly dry with temporary partly cloudy skies elsewhere.
Day temperature may rise slightly and night temperature may remain nearly unchanged, reports DT.
