Even though the forecast graphic above shows the 5 day rainfall forecast for Wednesday through Sunday, most of the rain will fall late Friday through Saturday morning.

Most of E TX south of I-30 and western NW LA will be under a Marginal Risk of excessive rainfall. This is where the heaviest rain will likely fall and where the threat of flash flooding will be greatest in the ArkLaTex. There is a Slight Risk of excessive rainfall just southwest of the ArkLaTex. The heaviest rainfall and greatest flash flooding threat will likely occur in the Slight Risk area.
