Wider weather episode

Storms developed just south of the I-70 corridor during the early morning hours of July 17th. With precipitable water values between 1.5 and 2.0 inches and the storms oriented in a west to east line, training caused heavy rainfall in some isolated areas with 1 to 3 inches (very localized 4 to 5 inches) of rain. So there were reports of flash flooding in a few locations.
