In brief: After one more very hot and sunny day, a modest pattern change arrives in Houston. This will bring improved rain chances into the area on Thursday and Friday, along with slightly cooler daytime temperatures over the weekend.

Rain, actually?

Most of Houston has not recorded measurable rainfall in more than two weeks. Officially, the city has received just 0.21 inches this month. Thanks to earlier rains in June and July, the greater Houston region still remains out of drought conditions. However we are starting to see rapidly drying vegetation, and background conditions that support wildfires are increasing. All of this is to say, we could use some rain.

Over the next couple of days a weak and dying front will move into the greater Houston region. It is not going to bring any meaningful change in our humidity, but it will perturb the atmosphere enough to bring some decent rain chances on Thursday and Friday. Most of the region is unlikely to see too much rainfall, but a few locations could pick up 0.5 to 1 inch of rain, or even higher isolated totals. Next week should also see slightly better rain chances as well, so with some luck our region’s very dry pattern in August should break, at least a little.

Wednesday

All of that talk about rain is going to have to wait one more day, however, as we experience another hot and sunny day with high temperatures in the vicinity of 100 degrees. Winds will be light from the southwest, picking up a little bit during the afternoon and evening hours. Lows on Wednesday night will drop only to around 80 degrees.

Thursday

This will be another hot day, with highs in the upper 90s to 100 degrees. We may see a few clouds in the sky, however, along with increasing rain chances that may take some sting out of afternoon highs. These rain chances will persist into the overnight hours.

Friday

Another day with a healthy chance of scattered showers. Additionally, partly cloudy skies may hold highs in the low- to mid-90s, which is more typical for late August. Rain chances should diminish by Friday evening, with overnight lows dropping into the upper 70s.

Saturday and Sunday

The weekend should bring mostly sunny skies with highs in the mid-90s for most locations (possibly upper 90s for far inland areas). Rain chances will fall back to about 10 percent daily.

Next week

This period should bring typical late summer weather to Houston, which is to say highs in the low- to mid-90s and daily rain chances roughly in the range of 30 percent. While this is still pretty hot, it is notably more moderate than the last 10 days or so of ‘peak’ summer we have experienced in Houston.

In brief: In today’s post we review the state of the Atlantic hurricane season, which normally is taking off at this time of summer. Also we look ahead to a few more sizzling hot days before a slight cooldown this weekend to go along with some spotty shower chances. We take what we can get in late August.

Status of Atlantic hurricane season

Well, we’ve officially reached the point of summer when activity in the Atlantic Ocean typically starts ramping up. So far this year is off to a slow start, with just three tropical storms. How slow? When we look at a metric useful for gauging overall activity, “accumulated cyclone energy,” activity to date is just 14 percent of normal levels. Since 1950 only seven years have started off with less overall action in the Atlantic, Caribbean, and Gulf.

Now I want to be clear: I am not taunting Mother Nature with the following words. But in reality, the runway for the rest of this hurricane season, and the state of Texas, does not stretch endlessly toward the horizon. Rather, realistically, we have about one more month before the odds of a hurricane strike on the great state drop significantly based on historical norms.

We can be pretty confident that no storms are going to move into the Gulf during the next 10 days (a promising tropical wave that recently moved off of Africa, if it develops, almost certainly will not come this way). That leaves about three weeks in September—which is quite literally the peak of the Atlantic season—when we’ll need to keep a close eye on things. Will El Niño continue to suppress activity? Some of our latest sub-seasonal modeling indicates that this is likely to be the case, but we won’t know for sure until we actually get into September. With that said we are in about as good a position as one could be, regarding hurricanes, in late August.

Tuesday and Wednesday

The very hot and sunny conditions we’ve experienced of late will persist for the next couple of days. We can expect highs in the vicinity of 100 degrees, plenty of humidity, and warm, sultry nights. Winds will be light during the morning, but gust up to 15 or 20 mph from the southwest during the afternoon hours.

Thursday

Some time on Thursday the high pressure ridge that has been dominating our weather during the second half of August will start to pull back to the west. I’m not sure this will happen in time to impact temperatures on Thursday, which still should reach near 100 degrees. But we may start to see a few more clouds, and by Thursday afternoon or Thursday night there might be some modest rain chances returning.

Friday, Saturday, and Sunday

The weekend will bring weather that is more typical for late August, which is to say high temperatures generally in the mid-90s and spotty showers. Rain chances won’t be high, perhaps 20 or 30 percent each day. But that’s higher that we’ve seen in a while. Skies should remain mostly sunny, and any showers that pop up probably won’t last too long.

Next week

Most likely our temperatures will remain in the mid- to upper 90s for much of next week, with mostly sunny skies and slight chances of afternoon showers. Early September is typically not much different than late August.

In brief: In today’s post we discuss the very hot week ahead for Houston, but explain why this weekend should offer some slight relief. Could we actually see a little rain as well? Maybe. And we take a peek into the tropics, where the Atlantic is slowly waking up.

It’s been a hot one

High temperatures in Houston over the last four days have been sizzling: 100, 101, 103, and 101 degrees. We are going to continue to flirt with highs of 100 degrees, or just above, for most of this week as high pressure reigns supreme. Longtime residents of Houston will know that the period of late August often brings the most torrid weather to our region, and this year is delivering in spades.

However, we do have some hope on the horizon. No, I’m not talking about a bona fide cold front. It’s just too early to have any real hopes for that—check back in a couple of weeks on that score. However there is increasing evidence that high pressure will break down somewhat by Friday or so of this week, allowing for more seasonal high temperatures in the mid-90s and a decent chance of rain.

But it’s going to be scorching until then.

Monday

Today will bring more or less similar conditions to what we saw over the weekend, which means baking heat over the region pushing highs to 100 degrees or a little higher. (Coastal areas will remain cooler during the daytime, in the mid- to upper-90s). Skies will be sunny, with humid air. Nights will briefly fall into the upper 70s. Winds will be fairly calm in the morning, with gusts up to 20 mph from the south-southwest during the afternoon and early evening.

Tuesday, Wednesday, Thursday

Conditions are more or less the same, but we might shave 1 or 2 degrees off of daily highs such that, by Thursday, most of Houston is in the upper 90s. Sunny skies and plenty of humidity remains.

Friday

Expect highs in the mid- to upper-90s on Friday with partly to mostly sunny skies. As high pressure breaks down we should see some (fairly weak) disturbances start to rotate through. This could bring a modest chance of rain into the region, something like 20 or 30 percent. It’s not much, but we’ve been so bone dry of late anything would be welcome.

Saturday and Sunday

The weekend will bring fairly typical weather for late August, with highs generally in the mid-90s and a chance of afternoon showers along the sea breeze. If you’re planning on outdoor activities you can expect plenty of sunshine, but there will be the possibility of some brief, passing showers.

Next week

Summer is not over, of course, when we reach September. For most of next week, at this point, I expect highs in the mid- to upper-90s with some slight rain chances. So still very warm outside.

Atlantic tropics

Over at the Eyewall, Matt has a good summary of the Atlantic tropics. The area of most note is a wave emerging off of Africa today, which has a decent shot of development over the next week. Overall this is something we’re definitely going to watch given the time of year, but it’s not something we’re at all concerned about at this point.

In brief: Our second 100 degree day of summer was recorded yesterday, and several more may follow. Although records are safe, continued near 100 degree weather will be with us into next week. Perhaps a slight rain chance this weekend will boost your mood? We explain and have some energy saving tips from our partners at Reliant in today’s post!

Had enough yet? Look, it has not been awful by August standards as Eric has written this week. We’re certainly nowhere near records. And we hit 100 yesterday for only the second time this summer. 2026 is currently sitting outside the top 10 of hottest summers on record in Houston, which would be the first one to fall short since summer 2021. That said, we’re only about 0.2 degrees of average summer temperature away from breaking into it again, and there’s a chance the late August rally here will get us there. I guess the better question is not how much longer the heat will last but whether we’ll see any rain.

Today

I won’t give you false hope today. Expect sunshine and heat and highs around 100, give or take. There is a weak little boundary, however that’s going to try to approach the Houston area late this evening, likely sometime after 8 or 9 PM. There should be a broken line of scattered showers and storms with it as it approaches. Those may vanish on approach given the time of day — or they’ll try to hold together and bring the area a little relief.

Emphasis on “a little.” Whatever the case, as Andy Dufresne reminded us “Hope is a good thing, maybe the best of things, and no good thing ever dies.” Speaking of…

Weekend

Both Saturday and Sunday should be scorchers. Expect highs around 100 to 103 and a Super Mario 2 sun. But Saturday has a little interestingness to it, with a chance that a few isolated thunderstorms pop up across interior Texas and drift southward toward the area. I’m skeptical any of those will make it to Houston, but I suppose someone, particularly north of Houston could see a mercifully cooling downpour on Saturday afternoon or evening. Maybe even a few folks! Probably not Sunday though.

Next week

High pressure peaks over Texas this weekend and then begins a retreat back into the Desert Southwest next week. There usually is no on-off switch in Texas August though, and in this case, the high pressure system should remain close enough to keep us hot but maybe not to the levels we see this weekend. As Eric rightfully noted yesterday, there are (were?) some models trying to pull back a good bit on the heat toward the very end of the month, but it seems like those model runs may have been aberrations.

The region is fully highlighted in risk for “extreme heat” through the end of August, and although temps may “only” be upper-90s to near 100, the compounding effect of strong August heat can begin to wear on you after a while, so be sure to try to keep cool. And think about conserving energy where you are able. Which brings us to a word on that from our partners at Reliant.

A message from Reliant

We’re entering the stretch of summer where the forecast is often the same day after day: HOT. When temperatures are high, air conditioners have to work harder to keep homes cools. Reliant is helping Houstonians save money and cut back on energy use while still staying comfortable this summer with the following tips:

• Follow the “four-by-four” principle instead of turning off your HVAC system completely. Set your thermostat four degrees higher when you’re away from home for more than four hours to reduce electricity usage while staying efficient upon your return home.
• Leverage smart thermostats and smart home devices, which are powerful tools to manage energy usage while away and optimize schedules while home.
• Grill outdoors. Cooking indoors raises the heat, requiring the AC to use more electricity.
• Use heat-producing appliances like the dryer, dishwasher, or oven after sundown instead of during the hottest times of day.
• Avoid running your pool pump all day by using an automatic timer.
• Set your ceiling fan to rotate counterclockwise to create a wind chill effect. Also turn off fans when you leave the room.
• Close blinds and shades to prevent heat buildup and get the most out of the cool air coming from the AC.
