What's the difference between a lightning storm and a severe Speed Force discharge??

Well, one is a naturally occurring event hosting a modest amount of lightning. The other?

The other boasts a constant lightning barrage that usually follows The Flash until he slows to a jog at 700mph.

Made from 100% cotton, our bright red Flash Bolt Symbol Storm Youth T-Shirt features a classic image of The Flash, aka Barry Allen, instigating several hundred Speed Force discharges per second as he constantly befuddles our timeline.

Yep, this Flash t-shirt for kids sports a very happy Barry Allen lost in his element -- a Speed Force-induced slipstream which lights up the sky and renders umbrellas thoroughly useless.
