Stellar weather continues for Houston, but the humidity will be creeping back in this weekend

It’s tough to argue with the stretch of weather we’ve had this week. It’s been warm, certainly, but with pleasant mornings and evenings and generally low humidity, it’s been pretty outstanding. We will have changes beginning this weekend, and those will set the stage for our weather next week.

Today & Saturday

Both days should be sunny and warm. Look for highs near 90° today with generally low humidity. A similar story unfolds tomorrow with perhaps just a few more fair-weather clouds dotting the sky. Morning lows will be in the 60s or low 70s again. The dewpoint, or how much moisture is in the air will be a couple ticks higher tomorrow, so you may notice it feels a bit more humid, especially in the morning. Patchy fog is also possible in the morning.

Two other quick notes: Air quality has been atrocious this week. The combination is two-fold: An inversion (temperatures warming as you go up in the atmosphere) has trapped pollution and smog near the surface in the morning hours leading to an ugly haze. That should continue today and perhaps tomorrow. Secondly: The full sunshine has led to high levels of ozone each day in the area. This isn’t as visible to the eye, but it can trigger some respiratory ailments in people. On top of all this, if you’re a seasonal allergy sufferer (raises hand), you’ve felt it this week. Ragweed is a big problem, as are mold spores. But, I mean, aside from that, it’s been great!


Our transition begins in earnest on Sunday. You’ll notice it a couple ways. First, expect sun and a few more clouds. Second, there could be a few light showers around, especially in the morning hours and especially southwest of Houston. The humidity will also be noticeably higher. In addition to all this, you’ll also notice the wind pick up Sunday. We’ve had a pretty lengthy stretch of light or calm winds this week, but onshore flow builds on Sunday with some 20 to 25 mph gusts possible, particularly near the coast. I don’t think this will be so much wind that it will impact Wings over Houston, but it’ll be a noticeable change.

While not particularly troublesome, wind gusts of 20 mph or so will be possible by Sunday afternoon, which is more wind than we’ve had all week. (Weather Bell)

Look for high temperatures on Sunday in the mid to upper-80s after morning lows in the 70s.


A cold front will take a swipe at the area on Monday, but it will likely come up short, fizzle, and/or quickly retreat back to the north. It will come close enough however to set off a few showers or storms Monday. We aren’t expecting anything too widespread, but some areas may see their first measurable rain in a good while. Look for warm and humid conditions with a continued onshore breeze. Expect mid to upper-80s after morning lows in the 70s.


Tuesday through Thursday get a little more murky. The general expectation should be for warm, humid weather to continue. We’d likely see highs in the 80s and lows in the 70s. We would have at least a few showers in the area each day, but I am guessing the atmosphere will be fairly “capped” next week, meaning thunderstorm development would be tough to come by. That’s a typical Houston-area setup in autumn. Clouds and sun would take turns each day, aside from the isolated showers.

Late week

Here’s where the fun begins. When I wrote my post last Friday, I noted that there was no sign of a meaningful cold front for the foreseeable future. I cannot say that this week, however. Model support and evidence is building that a cold front, possibly a strong one, will push through the region sometime late next week or weekend. Over 90 percent of the Euro ensemble members (shown here) and over 50 percent of GFS ensemble members (not shown) have some sort of front pushing through next Saturday-ish.

Model support for a legitimate cold front is increasing for next weekend with lows in the 50s possible once again. (Weather Bell)

Of those Euro ensemble members, about 65% have lows in the mid-50s or cooler possible next Sunday or Monday the 18th. We will see if that can get us into our rhythm for the cool season here, which typically sees a front at least every week or so. Obviously, folks will be watching cold fronts with a little more urgency this year after February’s disaster. It’s still quite early, but we’ll be watching closely through the winter too.

  1. I thought storm-preventing atmospheric capping inversions were mostly a winter and spring thing, due to the cooler water of the northern Gulf of Mexico? Do you think there be good area-wide rainfall with the cold front?

  2. Matt, I LOVE Space City Weather, but to call these horribly, miserably hot days “stellar” doesn’t match with my perception of what is p
    leasant. Stellar means the 70’s with no air conditioning cycling on.

  3. Thank you for posting the link about inversion. The technical explanations for the weather we experience is what I love most about Space City Weather. Thank you for all of your effort and for this product!

  4. These last few days haven’t been the most beastly in terms of pure temp/humidity – but, as noted by Matt, the inversion is holding the pollution right in our faces. The ozone + ragweed is not helping, too.

    As someone else with allergies, it is a constant mental scan for me to say: “What of the many factors out there could be causing me to feel blergh?” Then, I go through the checklist: humidity, temperature, ozone, allergens. It is a rare day that none of those tick the box.

    That being said, hooray for the crystal ball seeing a decent cold front for next weekend to usher in “Fall for Real” by mid-October.

  5. If you can find complaints about the last few days weather you are really trying hard. It’s great to have a few days without rain. Not looking forward to anything cooler than this. Winter kills, as you learned earlier this year. I am going to plant garlic and also arugula and a variety of kale this weekend or next.
