Heat Fueling Severe Storm Development
Extreme summer heat and abundant humidity continue to build instability across much of the central and eastern United States. As cooler air interacts with this unstable atmosphere, explosive thunderstorm development becomes more likely.
This combination of excessive heat and strong atmospheric dynamics is expected to continue supporting severe weather through the remainder of the week. (AP News)
