Houston weather: More summer sizzle and evening thunderstorms Monday

Forecast at a glace:

Hot and humid conditions will continue into the beginning of the week. Stray sea-breeze showers and pop storms will return to the forecast again on Monday. We can’t rule out a few stray showers in the morning as well.

A few storms coming early week:

A weak front will fall into Texas overnight and the leftovers will linger into Monday and Tuesday as it slowly pushes south in the state. That means we could see afternoon storms both Monday and Tuesday for your evening commutes, both from the sea-breeze and what’s left of the frontal boundary.

Temperatures will stay very warm for this time of year, though. We’re still mainly dominated by a large ridge of hot, high pressure sitting just east of Houston. Meaning, even if we see a front or two move through, there is not enough cool air to punch the ridge out of the way, so we’ll stay hot and dry.

Tracking the tropics:

Storm development chances in the Gulf are still very slim, however, we now have Tropical Storm Fay, recently formed in the north-central Atlantic. Fay is a fish storm and will remain out in the open Atlantic.

So far this hurricane season, we have not had a hurricane form in the Atlantic basin. The latest first hurricane to form was Gustav and Humberto, which formed on September 11th. This means our 2026 hurricane season set a record for the latest hurricane to form.

There is no big cool down in the forecast. There are periods of dry air, but highs are in the 90s for the next 10-days. More storms are possible Sunday, Monday, and for the official start of Fall Tuesday. On Monday September 21st the average high temperature falls to 89°! We however, are above that number next week.
