Details on Today's Severe Weather Risk

What is "The Cap"?

Weekend Warmth

A Marginal (Level 1 of 5) to Slight (Level 2 of 5) Risk for severe weather is in place, mainly over northern SD (along and north of US-12). Storms may have difficulty forming due to a capped setup. Wind gusts of 60 mph and hail of 1" in diameter will be the main threats.

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.

By this weekend, much of the area will see temperatures in the upper 90s to low 100s. The best chances to see highs over 100° will be along and west of the Missouri River. This level of heat will impact anyone without adequate cooling or hydration, particularly those sensitive to heat.
