Early Friday morning showers, then Friday afternoon break before heavier weekend showers

Expect scattered showers and thunderstorms on Friday for the early morning commute with heavy rainfall at times near the coast, in urban areas on street ways, and to the south of I-10. These locations will be in the most favorable zones for the heaviest rain and flash flooding possibilities from early Friday morning through Sunday evening. The heaviest showers and thunderstorms will take place early Friday morning, then taper off by the afternoon hours, then will resume in the evening hours of Friday, and will continue with scattered showers and thunderstorms that will be heavy at times all throughout Saturday and Sunday. Rainfall may reach anywhere between 3-5 inches from Early Friday morning through Sunday evening.

Temperatures will be in the mid to upper 80s as the highs on Friday through Sunday with the lows in the mid to upper 70s. Conditions will briefly feel more seasonal and cooler as a cold front associated with an upper level low pressure system will slowly pass through the region over the weekend. Flash flooding is possible all weekend due to these incoming heavy showers and thunderstorms.

Mostly cloudy skies will persist throughout the weekend. Winds will remain breezy all weekend.

Tropical Update

The National Hurricane Center has shown that a new weak low pressure system has formed in the Atlantic Ocean a few hundred miles southeast of Bermuda. However, due to the strong wind shear aloft and the drier conditions over the weekend, this system will remain weak and disorganized. By Sunday, this system is expected to end its cyclic development and become occluded quickly due to these conditions. Therefore, southeastern Texas will remain tropical storm free due to these incoming results along with the supportive ongoing strengthening EL Nino conditions.
