Soaking Rain in Tennessee and Texas

Surface map at 1:00 a.m. CDT April 28
Heavy thunderstorms brought inches of rain to several counties in southeast Texas and a large portion of northern Tennessee and adjacent portions of Kentucky, and both were the result of the same general weather system. The clusters of thunderstorms in Texas developed ahead of a front draped across southeast Texas. The thunderstorms in Tennessee were associated with a low pressure wave
moving northeast along that front. Precipitation from these storms topped five inches in both states, with heavier amounts more widespread in Tennessee.

The clusters of thunderstorm developed over Texas during the afternoon. Rainfall amounts exceed 6 inches on the northeast side of Fort Bend County. CoCoRaHS observers in Sugar Land reported 6.55 and 6.12 inches of rain.  Numerous rainfall reports of 4 to 5 inches was also observed in Lavaca, Harris, and Goliad counties
