Environment

Several short waves tracked across the region June 29th and 30th in advance of a cold front. These short waves interacted with a very moist air mass to produce pockets of heavy rainfall. Little in the way of severe weather was noted these two days due to the marginal nature of the instability and wind shear profiles. The biggest impacts were from heavy rain which led to flash flooding across portions of northwest Ohio.
