Much-needed rainfall is expected across Southeast Texas heading into the weekend, although rainfall amounts could vary significantly depending on location. The greatest potential for heavy rainfall through Friday remains west of the Houston metro area, while rain chances are expected to shift closer to the coast over the weekend.

A slow-moving weather system continues to produce moderate to heavy rainfall across Central Texas. Meanwhile, increasing Gulf moisture is bringing scattered showers northward into Southeast Texas.

Through Friday, the greatest potential for heavier rainfall is expected west of the Houston metro area. Rainfall will gradually spread east, but a large difference in rainfall totals is possible. Areas east of I-45 may see less rainfall through Friday.

Rain Chances Shift Toward the Coast This Weekend

Over the weekend, a weak frontal boundary is expected to move toward the coast while another weather feature develops over the northwestern Gulf of Mexico. Together, these features could focus more showers and thunderstorms near the coast.

There is still uncertainty about exactly where the heaviest rainfall develops. A shift of just 10 to 20 miles could make a significant difference in rainfall totals, particularly for areas south of I-10.

Residents should keep a few things in mind:

• The highest heavy rainfall and flooding threat today and Friday remains well west of the Houston metro area.
• Passing showers and thunderstorms will be possible throughout the weekend, but it will not rain continuously.
• Sunday currently appears to be the drier of the two weekend days as rain chances shift southward.
• A cold front is expected to move into the region next week.

Keep an Eye on Conditions Near You

Even when widespread flooding is not expected, rainfall can vary considerably across Harris County. The Harris County Flood Control District encourages residents to monitor conditions using the Harris County Flood Warning System, where users can view rainfall totals and water levels at gages throughout the region and sign up for alerts.
