A mild cold wave is likely to affect parts of northern, western and northwestern Bangladesh during the first half of February, according to Bangladesh Meteorological Department.
The cold wave may push temperatures down to between 8.0°C and 10.0°C in some areas, it said though no severe or prolonged cold spell is anticipated.
The outlook was shared at a meeting of the expert team on Long Range Weather Forecast held on Saturday afternoon at the Storm Warning Centre in Dhaka.
Despite the cold condition in certain areas, both day and night temperatures are forecast to rise gradually and remain above normal across the country over the month, indicating that winter is likely to ease rather than intensify.
Besides, moderate to dense fog is likely to form over river basins during the early hours while light to moderate fog may occur elsewhere in the country in the first half of the current month.
Rainfall is expected to remain below normal nationwide throughout February, the department said.

There is also no possibility of cyclones or depressions forming over the Bay of Bengal during the month.
However, forecasters cautioned that isolated thunderstorms accompanied by hail may occur for one to two days during the second half of February, a typical pre-monsoon transition feature.
