Let us be near the northern/northeastern periphery of the biblical heat and humidity with a 750-400mb WNW flow of at least 50-60+kts, MLCAPE of at least 5,000 J/kg, DCAPE AOA 1500 J/kg, and steep mid-level lapse rates. Then come August through October let us be near the west-end of a monster Bermuda High with an Ohio Valley trough stuck to our west so some fun spinny cloud masses will train up the eastern seaboard.
Then it will REALLY be "Game On".
