Mesoscale Convective Systems

Mesoscale Convective Systems (MCS) are large, organized groups of thunderstorms that form and move together over a regional area, often stretching hundreds of miles. They include clusters of thunderstorms, lines, or complex cloud formations that can produce heavy rain, strong winds, hail, and sometimes tornadoes. These systems usually develop when moist air rises, cools, and condenses into storms, often during thunderstorms or severe weather outbreaks. MCSs can last for several hours and significantly impact weather patterns, especially in terms of rainfall and potential flooding. They are important to monitor for weather forecasting and safety.
