Fannett, Texas saw 7 inches of rain in ONE hour. Lake Charles saw two separate hours with more than 2" of rainfall. Several cities saw record rainfall Monday.
Flood watches have already been issued from near Little Rock through the Arklatex southward to the Gulf of Mexico coast in anticipation of additional heavy rain and possible flooding. Rain totals could be higher than 6" in spots where repeated rounds of rain will develop.

This is guidance for where some of the heaviest of the rain could be but is not a set-in-stone forecast. Generally 1"-3" of rain looks to be widespread with localized areas getting 4-6"+ of rainfall accumulation. These areas are still soaked so any heavy rainfall could lead to flooding.
Severe thunderstorms are also possible today (Friday) including Houston, Lake Charles and Lafayette. With modest shear in the atmosphere (wind direction changing as you go up in height in the atmosphere), brief tornadoes are possible.
