In terms of temperatures, daytime temperatures may rise by 1-2°C in Rangpur division, while remaining relatively stable elsewhere. Nighttime temperatures are expected to remain largely unchanged across the country. Excessive moisture content may lead to discomfort.

According to Tuesday's forecast, two places in Mymensingh and Sylhet divisions may receive rain with gusty winds or thundershowers temporarily.
