Showers may linger into Monday
Further showers are possible on Monday as thick cloud keeps afternoon temperatures in the upper 60s to low 70s. Rain chances should ease on Tuesday, although cloudier conditions and a small chance of showers may remain.
Forecasters expect the next cold front to reach the Houston region late on Wednesday night or during the early hours of Thursday. It should bring drier and cooler weather for the remainder of the week.

Highs are forecast to reach the upper 70s on Wednesday and Thursday before falling to the low 70s on Friday and Saturday. Morning temperatures will dip into the 40s and 50s once the front has passed.
