Went out just as the afternoon thunderstorm clouds started rolling in. Temps were feeling just above 100F in the sun as I started my run, so the clouds were welcome. Heard my first thunder boomer about 5K into the run, but no sign of lightning. 8K in had a few spits of rain and the winds picked up. Funny running through pockets of hot humid air and cooler air from about 8-9K. Heavens opened up between 9-11K, it felt great. 12.75K all together.
