Heavy Rainfall And Flooding Threat Gradually Shifts From The Western Gulf Coast To The Mid Mississippi and Ohio Valleys and Mid-Atlantic Region; Excessive Heat Consumes Desert Southwest.
A low pressure system will advance slowly south and west from south TX into Mexico, which will gradually curtail the torrential rainfall and flooding in south/southeast TX. Focus for heavy flooding rain will shift to the Mid MS/Ohio Valleys and Mid-Atlantic, as an area of low pressure tracks very slowly along a moist stationary front. Finally, Heat will be the word in parts of CA and Southwest.
