Houston Weather Forecast: Rain chances increase this week ahead of the first front of fall
Rain chances increase day by day through Wednesday as the first cold front of fall approaches Southeast Texas. A few showers and storms possible Tuesday and Wednesday.

HOUSTON, Texas (KTRK) -- Fall is here, but summertime temperatures stick around for several days this week. The first fall front will approach Southeast Texas though midweek, potentially bringing some much needed rain to portions of Southeast Texas. We're also keeping a watchful eye on the gulf with an area of interest now in the western Caribbean.

A brief shower passed through downtown Houston Sunday evening and there's a better chance for more isolated activity across the region Monday. Temperatures Monday will start in the low-mid 70s with afternoon highs back in the low 90s. there is a 20% chance for showers too in the afternoon as a sea breeze develops and move inland.

How long do you expect these summertime temperatures to continue?

High temperatures should remain at or above 90 degrees for several days this week. However, the combination of the midweek cold front and what could be hurricane Helene in eastern gulf could decrease the humidity, so it might not feel as hot later this week. Needless to say, temperatures will be near or above 90 degrees all week.

Any promising rain chances in the near future?

A cold front will approach Southeast Texas Tuesday and Wednesday of this week. And while this front won't bring the first taste of fall this time, it could help produce some showers and storms each day depending on when the front arrives. This front will also probably not make it to the coast, but there is a 30% chance for rain for everyone Tuesday and 40% on Wednesday.

How long will we have to wait for our first real taste of fall air?

At this time, it looks like we'll have to wait until the first week of October for any chance of a meaningful cool front to visit us here in Southeast Texas, but next week's front should at least drop the humidity and bring us some mornings in the 60s by next weekend.

What are you tracking in the tropics?

We continue to see signs that a tropical low could lift out of the Caribbean and into the Gulf next week. There are a lot of scenarios on the table for what it could do and where it could go, so our best advice right now is to simply stay weather aware until we get a better handle on where it is most likely to track.
