This included minor wind damage reports from West Virginia to Texas, along with some hail reports in this same area. On Saturday severe weather was found in Mississippi as well with damaging winds. The heat continued in the Southwest, however the Southern Plains got some temporary relief from the heat in the form of flooding rains.

Interaction with a frontal boundary and return flow will set the stage for thunderstorms along the Gulf Coast and into the Southern Plains. Nice weather is in store for the Northern Plains into the Rockies and out West. The heat will be over the Southwest again and the Northern Plains will begin to warm.

Ask The Weatherman for July 15, 2013:

Question: What type of thunderstorms form near a cold front?

Answer: There are multiple types of thunderstorms that form near a cold front. The first is called a frontal thunderstorm. These usually form at the frontal boundary. The second is the Mesoscale Convective Complex and also the Mesoscale Convective System storms and the major one that forms out ahead of the cold front is the Super-cell thunderstorms. All of these thunderstorms have the potential to be severe – creating damaging winds, large hail and tornadoes.
