Episode narrativeepisode_narrativeOn Friday, May 17th, a slow-moving upper level low was rotating across the mid Mississippi River Valley with an associated surface low over Arkansas and surface trough extending southeastward into Alabama. Warm, moist airflow resulted in widespread showers and thunderstorms across northwest Central Alabama during the day, while stronger thunderstorms developed south of the rain area in a more unstable airmass. Some of these storms produced large hail. As this area of rain shifted east through the evening hours on Friday, May 17th, additional thunderstorms developed upstream and tracked across east Central Alabama. A mid level short wave rotating around the upper level low interacted with a low level convergent zone and continued moisture transport into the area to focus developing thunderstorms, which then tracked over the same areas for many hours, resulting in flash flooding during the early morning hours on Saturday, May 18th. Precipitable water values were around 1.70 inches, the 99th percentile for normal precipitable water values for that day. Rainfall estimates of three to five inches with localized amounts over eight inches occurred.
Event narrativeevent_narrativeApproximately two inches of rainfall across the area led to water covering portions of U.S. Highway 78 northeast of Heflin.
