Severe Storms and Flooding from April 30th - May 1st 2004

This was the second system in a week that brought severe storms and flooding to the Missouri Ozarks and southeast Kansas. Another slow moving cold front pushed into the region by the afternoon of April 30th. Showers and thunderstorms with heavy rain occurred during the morning and afternoon hours across portions of central and south central Missouri leaving the ground mostly saturated. Some isolated severe storms developed with large hail, however the majority of the storms were just producing torrential rainfall.

Thunderstorms formed into a complex during the evening hours of the 30th and extended into the early morning hours of May 1st. The heaviest rainfall occurred across southern Missouri in areas where major flooding occurred just one week prior. With ground levels remaining nearly saturated from the previous weeks heavy rain, it did not take much additional heavy rain to flood these same areas again.

While the heaviest rainfall ended early on the morning of May 1st, some light to moderate rain continued to develop behind the front as upper level energy moved through. Rain finally ended from west to east during the evening of May 1st.

Despite the end of the rainfall, low water crossings remained flooded into the late night hours of May 1st and early morning on May 2nd.
