Imagine sleeping with the window open.. a cool breeze coming in. And suddenly within a matter of a few minutes –after midnight–the temperature rises 20 DEGREES? It happened this week.

And now experts are trying to explain the strange heat burst in Wichita..

KSN explains: A heat burst is caused when rain falls into very dry air, high up in the atmosphere. The rain quickly evaporates as it falls through the dry parcel of air and that parcel cools rapidly. This dense mass falls rapidly toward the ground, heating up as it compresses. When this hot ball of air hits the ground it spreads out in every direction creating very strong, warm and dry winds.

It’s rare. It’s weird. And it happened.
