Details on Today's Severe Weather Risk

What is "The Cap"?

Thunderstorms are possible (15-30% chance) over northern SD late this afternoon and into the evening hours. The storms will initially develop in north central SD and south central ND before moving quickly to the southeast. As the storms move southeast of US-12, they will diminish.

Storms on Friday will have a conditional risk, meaning that storms may or may not form. Storm formation may be limited by "The Cap", or a layer of warm air above the surface. It is only if rising air con overcome this cap that storms may develop.
