What way will the weather warp and wrestle wealth and weakness for weary RPG warriors?
While I'm not yet all that well acquainted with your setting, that much energy from sun would be more likely to prevent supercell creation in that region. Very high rate of convection would force high-altitude winds to dissipate that. The hell would break elsewhere, after heated air would travel and break the cold front. I know that it's RPG so most of that should be hand-waved to have fun instead of learning stochastic calculus. Plus I'm hardly an expert on the subject, but amount of heat is not directly proportional to storms.
Sorry for nit-picking, it just hit me in the eyes ;).
