Month: August 2024

In brief: Houston will face some of its hottest weather today and Saturday before a weak front makes its last gasp over the area. We cannot rule out a few thunderstorms on Saturday evening, and then some showers on Sunday, but for the most part our weather this weekend and next week is going to be hot and sunny.

Friday

High pressure will be dominant today and for much of Saturday, leading to some of our hottest conditions so far this summer. Friday, therefore, will likely a little bit warmer than we’ve experienced that last couple of days even. Most of the Houston region, away from the coast, is likely to see highs pushing into the upper-90s. Winds will be light, from the south at only 5 mph. With dewpoints in the mid- to upper-70s, the air will feel sticky. Low temperatures tonight will only fall to around 80 degrees for much of the city. So yeah, this will be full-on summer in Houston.

Saturday

The first half of the weekend is likely to be even a touch warmer than Friday. This will be due, in part, to the advancement of a weak front that will eventually fizzle out over the Houston area. What happens as a front advances is that, typically, it compresses the air ahead of it downstream. The front is fairly weak, but this compressional heating could be enough to add a couple of degrees on Saturday. Therefore I expect most of the region to reach the upper 90s, with a few locations possibly hitting 100 degrees. Skies will be sunny during the daytime. I do think it’s possible that we see some isolated or scattered showers on Saturday evening, with the possibility of thunderstorms. So while these aren’t probable, they are possible.

Sunday

The front should bring a few degrees off the top end of our temperatures, so highs on Sunday will likely drop back into the mid- to upper-90s. There is also a decent chance of showers on Sunday and Sunday evening. By decent I mean maybe 30 percent for areas along and south of Interstate 10, and 20 percent further inland. Mostly, however, our skies will be sunny and the air plenty humid still—sorry, it’s a very weak front that will fall apart as it pushes into the region. Lows on Sunday night will drop into the upper 70s.

Next week

Most of next week looks sunny and hot, with high temperatures in the mid- to upper-90s. There will be a smattering of rain chances, but they’re low overall, perhaps 10 to 20 percent daily. Mostly, it’s just going to feel like Houston in August. For most of us, that’s pretty miserable. But aside from the heat we should have no worries about storms or the like, which is nice after what Houston has experienced so far this spring and summer.

Tropics

The forecast for the tropical disturbance AL97 is coming into better focus, and it looks to be a rainmaker for Florida and potentially the US East Coast this weekend and into early next week. As we’ve been saying for a few days, there is zero threat to Texas from this system. We’ll continue to track the storm in depth today, and this weekend, on The Eyewall.

In brief: This post discusses the month of August, and why it is the worst month of the year for weather in Houston. It also delves into our hot and hazy weather ahead, and takes a peek at a tropical system that’s near Puerto Rico and may be a rainmaker for Florida next week.

A word about August

This month is named after the Roman emperor Augustus, who is considered by some historians to be Rome’s greatest ruler, and by others a tyrannical usurper. His greatest crime, however, is renaming this month after himself. Prior to that little matter of self-aggrandizement, the month was called Sextilis. That would have made an interesting naming choice for our hottest and steamiest month.

In any case, August is the worst month because it is the hottest month of the year in Houston. And we typically vacillate between the extremes of drought and flood, sometimes within a matter of hours. There is no happy medium. There is no break from the humidity. There is only August. It is also the month, alongside September, when we are most vulnerable to landfalls from major, destructive hurricanes. Now my colleague Matt Lanza will argue that September is worse. Why? Because September can also be hot, and there is the often false hope of a a cool front. But let me tell you, Lanza is dead wrong. I have lived through enough Septembers in Houston to know that we very often do get our first front in September, and it feels glorious.

Anyway, August is here. It’s always hot. It’s always humid. Let us fervently hope it is hurricane-free.

Thursday

There will be plenty haze again today, which will fade the blueish nature of the sky, as we continue to see an influx of Saharan dust. This haze, at varying levels, should remain with us through Saturday or so. Otherwise, beneath high pressure, we should see sunny skies and hot temperatures in the mid- to upper-90s. Winds will be light, out of the south or southeast, at 5 to 10 mph this afternoon. Lows tonight will only drop into the upper 70s. And humidity—well, you should know whether to ask about humidity in August.

Friday and Saturday

Temperatures will likely peak these days, with high temperatures likely in the upper 90s for much of the metro area. As mentioned above, we should still see a fair bit of haze from dust. However, beyond the haze we’re going to see sunny skies and rain chances below 10 percent. These will be good beach days or otherwise suitable for outdoor activities near water.

Sunday and Monday

A weak front is going to near the Houston region on Sunday, and this may bring a few more clouds. (Although I’m still going to bet on mostly sunny skies). Rain chances will be a little bit higher, but still on the order of only about 20 percent daily. Temperatures may fall back a degree or two, into the mid- to upper-90s. Still, it’s going to be plenty hot.

Remainder of next week

We’ll continue to see hot and mostly sunny weather for much of next week, with highs in the mid- to upper-90s. There’s the slight potential for some sea breeze showers each afternoon, and maybe some slightly better rain chances toward the end of next week. But I’m not sold on that.

The Tropics

I’ll have more on the The Eyewall later this morning, but the forecast for a tropical wave that is now nearing Puerto Rico continues to fluctuate. For now it looks like a weaker system will move into the eastern Gulf of Mexico and eventually move north toward Florida. Then it may spin around awhile before finally lifting north. This is very likely not an issue for the Western Gulf of Mexico, but is definitely something to watch for Florida and parts nearby.
