Building toward a wet Friday before—most likely—a sunny weekend

After Tuesday’s stellar weather, conditions will turn a little bit warmer before a cold front sweeps into the area toward the end of the week. The big question remains when this will happen—anywhere from early to late Friday—and this timing will help determine how wet things get in Houston.


Most of the region is starting out this morning somewhere in the neighborhood of 60 degrees. An east wind will turn southeasterly later today, allowing for the onshore flow to resume. Winds could become a bit gusty this afternoon. All in all, however, this still should be a pretty nice fall day with high temperatures tickling 80 degrees and mostly sunny skies. Lows tonight should fall into the mid-60s for central Houston, a bit warmer to the north, and a bit cooler to the south.

This should be a more cloudy affair, as moisture begins to stream inland. This will augur the potential for some heavier rain, but for now this appears unlikely before sunset, and most likely after midnight. Highs Thursday will be in the low 80s, with ample humidity, and lows Thursday night probably won’t drop much below 70 degrees.


Friday is the big question mark. Simultaneously, a cold front will be moving southeast across the plains toward Houston, and a tropical wave will be pulling north from the Bay of Campeche. The amount of rainfall the region gets will be dependent upon the timing of these two systems, which remains hard to pin down. Our best guess is this setup makes for a wet period between late Thursday night and early Friday afternoon, with perhaps 0.5 to 2.0 inches of rainfall inland, and 2.0 to 4.0 inches along the coast, making for a wet end to the week. For now, we’ll predict a frontal passage around noon, but there remains some uncertainty in this. This will be a fairly strong front, with temperatures falling as the front passes.

Most likely, skies will clear out sometime on Friday night or Saturday morning, assuming a clean frontal passage. This will lead to mostly sunny skies by mid- or late-Saturday morning, with highs of around 70 degrees. This is our best guess at this point. Lows Saturday night will probably drop to around 50 degrees in Houston, cooler inland, warmer along the coast.


There’s a high probability of this being an exceptional fall day, with highs in the 70s and mostly sunny skies.

Next week

Look for a warm-up beginning on Monday or so before another front arrives later next week. The most likely scenario is that this front arrives on or before Halloween, making for a cool and dry evening for trick-or-treating. But am I ready to predict that with any confidence? I most certainly am not.

    Thanks guys. A+ for effort as this thing continues to throw out its uncertainty. I’m hoping for a very wet day but by no means am expecting one. Thanks always for a great job. GO STROS!!

    Eric can you tell me what Friday will look like – we have a pending golf tournament and unsure if we should cancel or not?

      There’s a lot of uncertainty regarding Friday’s forecast which I think Eric tried to convey. One model has a cold front whipping through quickly in the morning, meaning a brief burst of rain in the morning followed by cooler windy weather. But the other model has the cold from coming later in the day and going very slowly–not clearing out of the area until early Saturday–which means a rainy afternoon and evening on Friday.

        Thank you I do appreciate the explanation.

        I did read the Friday message above; just want more clarification as my supervisor was inquiring.

        I appreciate everyone’s expertise on this matter and your time to answer.

    Enjoyed the link yesterday to WAPO weather.

    I hate to say it, but the D.C. folks made a convincing case Houston weather is way worse than D.C. weather.

      January, maybe. Who knows anymore. My daughter was born in January and she spent her first birthday in shorts and sandals a few years ago.
