A very moist air mass was in place across the region on the afternoon of July 19th as a cold front approached from the west. Precipitable water values, which approached 2 inches, were 2 to 3 standard deviations above normal. A strong, low-level jet of 50 knots and flow that was nearly parallel to the front caused storms to train across the area, adding to the flash flood risk.. Numerous reports of wind damage and flash flooding were received during this event.
