Did the ECUSA General Convention cause the heavy rains in Ohio, West Virginia, Pennsylvania, and Maryland last week?

Let's look at the evidence:
Dark green and yellow areas on the map indicate larger amounts of rain.
We know that the urban heat island effect can cause enhanced rainfall amounts in areas downwind of urban areas. (that would be to the east in this part of the world) Notice where the heaviest rain was relative to Columbus.
Though Columbus is not the largest urban area in Ohio, the ECUSA convention there last week did generate lots of extra hot air. In fact, the daily high temperature in Columbus reached 91F on Thursday June 22, 8 F above the average high for that date.

So, it appears that such conventions really do generate more heat than light.

You make the call.
