The region’s streak of very hot days and record-setting nights continues as high pressure dominates Houston’s weather. Here are a few notable trends from the last week across the region.
Bush Intercontinental Airport recorded four consecutive days of 101-degree high temperatures through Sunday.
Galveston has had six consecutive days in which overnight lows have only fallen to 84 degrees, the second longest streak after the heat wave of 2011.
Houston’s Hobby Airport set or tied its record low temperature on August 7, 8, and 9 with lows of 80 or warmer.
All of these trends are likely to continue Monday and Tuesday as the ridge of high pressure continues to dominate our weather. Fortunately, the pattern should begin to change by the middle of the week.

Monday
A few, isolated areas of Houston saw some brief showers and thunderstorms on Sunday afternoon, as rising moisture was able to combat subsidence in the atmosphere. We may see a similar pattern today, with 10 to 20 percent of the region seeing brief showers. Any relief from the heat will be temporary, however, as we still expect a hot way with much of the area seeing 100 degrees. Nighttime lows will again be around 80 degrees for most of the area.
On Wednesday, officially, Houston came awfully close to 100 degrees. The temperature at Bush Intercontinental Airport spiked up to 99 degrees during the afternoon. Previously this summer, the high temperature had topped out at 97 degrees on several days. With high pressure now firmly in control of our weather, we can probably expect to hit the century mark today, or almost certainly in the coming days.
Thursday
A heat advisory is in place for today, with high temperatures likely in the upper 90s to 100 degrees, and the heat index—which factors in humidity—potentially reaching 110 degrees. Please take extra caution with mostly sunny skies, and very light southerly winds. We can’t entirely rule out a few stray showers and thunderstorms along the sea breeze, but precipitation is unlikely.
Friday, Saturday, and Sunday
The weekend will see more of the same, with highs likely to reach 100 degrees for inland areas, sunny skies, and warm nights with lows only falling to around 80 degrees. This is mid-August for you.

Next week
The heat will likely continue for the first couple of days next week before the high pressure dominating the region’s weather pulls back to the west. This may allow for a more northeasterly flow, some slightly less hot air, and perhaps some slight to moderate rain chances.

Rain showers over the last week have been completely hit or miss, with some areas such as Pearland or Baytown receiving 1.5 to 3 inches of rainfall, and many other areas including The Woodlands and West University Place getting none. As a result, some readers may think the last seven days have been quite wet, while others have watched the storm clouds form, only to hear distant thunder but see no measurable rain. What I’m confident of now is that virtually no one will see rain for the next week as high pressure settles in.

Wednesday
Today will still see a slight chance—maybe 10 percent?—of isolated showers along the sea breeze before high pressure truly clamps down on our weather. Highs likely will be otherwise in the mid- to upper-90s with mostly sunny skies and light southerly winds at 5 to 10 mph.
Thursday through Tuesday
There simply isn’t much to say about Texas weather in the summer, beneath high pressure. We will see highs in the upper-90s to 100 degrees. Skies will be sunny. Overnight lows will be in the upper 70s to low 80s. They say it’s not the heat, it’s the humidity? Well, my friends, in Houston we’re blessed with both.
Later next week
Forecast models indicate the pattern will finally break by the middle or end of next week, as high pressure weakens and perhaps a more northeasterly flow sets up across the region. This should bring high temperatures back down a bit, and nudge rain chances up somewhat. After a week in the fryer, we’ll be ready for any modicum of relief.
A broad dome of high pressure will still build across the Houston region later this week, but we should have another chance of showers today before the heat really sets in. This weekend, in particular, looks hot.
Tuesday
High-resolution models are showing 20 to 30 percent rain chances today, especially later this afternoon along the sea breeze. These showers will definitely be hit or miss, with most of us likely on the “miss” side. The HRRR model forecast below shows what the radar might look like at around 4 or 5pm this afternoon. High temperaturess will push into the mid- or upper-90s with partly sunny skies.

Wednesday
Still have a very slight chance of rain, perhaps 10 percent, as high pressure builds over the region. Highs will be in the mid- to upper 90s with light southerly winds.
Thursday through Monday
Honestly, there’s not much to say about the weather forecast, so why waste words? It’s going to be awfully hot. Temperatures will reach the upper 90s to 100 degrees for Houston, with mostly sunny skies and light winds. Overnight lows will be sultry, only dropping to 80, or briefly into the upper 70s, for inland parts of Houston. As ever, August is a rough month for the region.
Next week
When will the high pressure break? The long-term ensemble models suggest this may happen toward the middle or end of next week, but that’s pretty much at the edge of predictability, so who knows.
