An unusual late July weather pattern, set the stage for extreme rainfall amounts and major flooding across north central and northeast Missouri, on July 24th and 25th. Hot and humid air, continued to feed north across the eastern Plains into western Missouri. Meanwhile, a series of upper air disturbances had brought rainfall to the Mississippi Valley region and northeast Missouri, keeping temperatures much cooler. This reinforced a strong stationary front, that was draped from northeast into central Missouri on the 24th. During the overnight hours, a stream of strong winds developed several thousand feet above the ground, known as a nocturnal low-level jet. Typically these rivers of fast moving air, lead to nighttime thunderstorm complexes in May and June, but diminish as we head into the summer months. However, the  weather pattern resembled one more typical of late Spring. These winds transported very warm and moist air into the stationary front, leading to explosive thunderstorm development along the Iowa border. Thunderstorms then tracked southeast along the front, while continuing to regenerate further northwest. The result was extreme rainfall amounts, widespread flash flooding, and record river flooding. Rainfall amounts of 6 to locally more than 12 inches fell, with Unionville to Kirksville the hardest hit. Extreme rainfall amounts continued along the Highway 63 corridor, as far south as Moberly. The Chariton River near Novinger crested at 28.44 feet, or its third highest crest ever. The Chariton River near Prairie Hill, crested at its highest level ever, at 23.27 feet.
