Hit -- or got hit by -- a couple of real cloudbursts while I was driving on the New York Thruway, today. Rain came down in buckets -- traffic slowed to about 40 mph -- with rapid-fire lightning (the kind with multiple cloud to ground strikes that all follow the same path), and lots of hail (starting out as BB sized and going up to pea sized as the storm went on). The NY Thruway has some "issues" -- water pooled in the left lanes resulting in some accidents and lane closures. Coming back there was a lo-ooo-ong back-up due to a hillside collapse across all northbound lanes -- right by a "Watch for falling rocks" sign.
After all that, it still never actually got any cooler.
