Mostly cloudy, with high rain chances, especially near the coast.

A low pressure system in the Gulf, moving west toward the Texas coast, will bring a good chance of rain to the area today.

The National Hurricane Center gives this system a 20 percent chance of developing into a weak tropical depression or storm before it moves inland tonight or tomorrow morning. Dry air on the storm’s south side and some relatively high wind shear will likely prevent the system from developing, however.

Whether it does or not, however, the system will deliver deep tropical moisture into the Houston area, helping to fuel good rain chances through Saturday. Chances are especially high along the coast.

With tropical moisture, where storms do form rainfall rate could be extremely high, as much as 1 to 2 inches per hour.

The clouds associated with the rain showers should help to keep temperatures in the lower 90s for most of the rest of this week as well. Away from the coast temperatures could be warmer, in the mid- to upper-90s, as cloud cover should be less.

In addition to the Gulf system, Hurricane Cristobal is moving away from the United States, off the east coast.
