The severe storm threat today could have boom or bust potential. The threat for strong to severe thunderstorms depends on how much heat and humidity can develop ahead of a cold front today. If enough heat and humidity can develop, we will have a threat for severe weather. On the other hand, if there are too many clouds and showers through this morning, strong to severe thunderstorms may not be able to form today. In that case, we may end up with broader coverage of non-severe showers and thunderstorms this afternoon.
