EXPLAINER: What’s a “MCS?”

TULSA, Okla. — An MCS stands for a “Mesoscale Convective System,” which is a cluster of thunderstorms, often in the form of a squall line.

MCS span hundreds of miles and often involves high winds and torrential rainfall.

These are common in late spring and early summer in Oklahoma when storms fire late in the day to our northwest, congeal into a cluster and barrel our direction overnight. MCS are often fueled by strong, warm and humid winds just above the surface.

These can cause wind damage and are most common in the early morning in Green Country.

The FOX23 Severe Weather Center is expecting multiple MCS’s to push through our region this week.
