Isolated thunderstorms are possible throughout the Dallas-Fort Worth area, Burns said. Any storms that develop could bring street flooding, gusty wind and lightning. North Texas will get a break from the heat this week, with high temperatures expected to hang around the 80s and low 90s through Friday. Rain is in the forecast all week, Burns said. The lowest chances for rain will be on Wednesday and Thursday, but a tropical storm soaking South Florida could drop “lots of rain” on the Dallas area as it makes its way along Gulf Coast.
