Houston braces for flash flood threat as strong front approaches

A strong front is expected to arrive on Friday and bring with it the chance for heavy rain and minor flooding through parts of the weekend.

You can track radar here:

Thursday looks a little quieter, with a 30% rain chance and storms hanging around the coast in the morning and another round mainly popping up after 1 p.m.

The familiar summer sea breeze pattern will keep showers and storms hugging the Gulf coast for now, with north Texas starting to see more thunderstorm development as the front works its way south.

It’s not just rain—thunderstorms are expected each day as this front stalls over the region, with the highest impacts likely Friday through Sunday.

For folks planning weekend activities, keep an eye on weather alerts and never drive through flooded roadways.

There is a low flood threat for Friday and Saturday for all of SE Texas. This means some storms could produce heavy downpours that lead to ponding in roadways. Plan on extra time on the roads.

Flood Threat

Also, with the first weekend of high school and college football upcoming, a stalled front may make for some wet tailgating for the college games and high school kickoffs could see storms at times.

While August usually isn’t prime time for cold fronts making it all the way into southeast Texas, this system is showing signs it will push through the Houston area.

Sunday, Monday, and Tuesday are expected to bring morning lows in the lower 70s—a big change from recent weeks’ sticky 90- to 100-degree highs and steamy nights in the upper 70s.

For Labor Day itself, plan on a high temperature around 90 degrees and just a 20% chance of showers and storms, making for a much more comfortable holiday.

Tropical Outlook:

The tropics remain generally quiet and there is are no tropical threats to the Gulf at this time. Cherish this moment, it’s rare for late-August.
