A cold front is the leading edge of a cooler mass of air, replacing a warmer mass of air, often resulting in a drop in temperature and potentially severe weather conditions such as thunderstorms. It is characterized by a steep temperature gradient and is typically followed by clear skies and cooler temperatures after it passes.

Thunderstorms are meteorological phenomena characterized by the presence of lightning and thunder, often accompanied by heavy rain, strong winds, and sometimes hail. They form due to the rapid upward movement of warm, moist air, which cools and condenses to create cumulonimbus clouds, leading to atmospheric instability and convection currents.

Clear skies occur when there are no or minimal clouds in the sky, allowing for unobstructed sunlight during the day and a clear view of celestial bodies at night. This meteorological condition is typically associated with high atmospheric pressure systems and can influence temperature, visibility, and weather patterns.
