7/19/2017 7:00 AM 1.29 M M M M Plenty of rain has fallen early this morning due to a persistent train of thunderstorms. This was definitely much needed for the local area.
7/21/2017 7:00 AM 1.58 M M M M Storms with torrential rainfall occurred during the night. My backyard weather station recorded a rainfall rate of around 3" per hour at the peak of the storm around 1 AM. Will not select a flooding value since I wasn't actively watching at the time, but with such high rainfall rates, I would not be surprised if some minor flooding occurred.
7/22/2017 8:30 AM 0.36 M M M M Light rain with some thunder at observation time. I'm a little late though.
