Cooler temperatures forecast for most regions

This is due to a strong mass of cold air from China which is expected to cover the upper part of Thailand and the South China Sea, causing temperatures to drop by 3-5 degrees Celsius. The northeastern region will see a drop of 4-6 degrees Celsius, the eastern region will be 2-4 degrees C cooler, and the central region, including Bangkok and its vicinity, will lose 1-3 degrees Celsius.
