Will it snow when it is cloudy below zero?

Whether it will snow on cloudy days mainly depends on many meteorological factors such as temperature, humidity and airflow. If the temperature is below 0℃ and the humidity is high, it may snow on cloudy days.

Generally speaking, when clouds have appeared in the sky at high altitude, the temperature on the ground will gradually decrease. If the temperature is below 0℃ and there is enough water in the air, it may snow. At this time, air with a temperature lower than 0℃ combines with water to form solid crystals, thus forming snowflakes.

It is worth noting that the temperature below 0℃ does not necessarily mean snow. When the temperature is too low, the moisture content in the air may become very small, and even in cloudy weather, it is difficult to have snowfall. Under some special circumstances (such as abnormal local atmospheric movement and extremely high air humidity), it may snow even if the temperature is slightly higher than 0℃.

In short, whether it will snow on cloudy days needs to consider multiple meteorological factors, not just the temperature.
