Houston’s heat continues, with a slight mid-week downturn in humidity

After a hot weekend, with temperatures averaging about 10 degrees warmer than normal during early May, we’ll see a slight reprieve this week by Wednesday evening. But it will only be slight, and the latter part of this week looks to see continued hot weather. Our only foreseeable chance of rain will come next weekend, but I wouldn’t rate our chances at much higher than 30 percent right now.


To start the week we will see a continuation of conditions that prevailed over the weekend, which is to say mostly sunny weather with highs generally in the low-90s. Winds will continue to blow from the south, perhaps gusting to 20- or even 25-mph. Humidity will naturally be quite high as well. And overnight lows will not drop much below the mid-70s.

As we come into Wednesday, high pressure (deeper reds) will move almost directly over Houston. (Weather Bell).

Tuesday and Wednesday

This period will see more of the same weather, with highs in the low 90s, but this pattern will start to change by Wednesday afternoon or evening, as high pressure moves almost directly overhead. This will effectively put the brakes on the southerly flow, and help to bring a little bit more dry air into the region. We’re not talking anything crazy, but lows on Wednesday night should drop into the mid- to upper-60s for areas away from the coast.

Thursday morning’s low temperatures will be slightly cooler and drier. (Weather Bell)

Thursday and Friday

Both of these days will be hot, with highs in the low- to mid-90s. But some slightly lower dewpoints will make conditions feel a little bit less humid. Not much, mind you. But long-time residents will probably be able to detect a difference. Overnight lows should drop to around 70 degrees. Mornings and evenings will be fairly nice.

Saturday and Sunday

The outlook for the weekend calls for mostly sunny and hot weather, with highs in the low- to mid-90s. The only real question is whether a weak atmospheric disturbance will be able to provoke some showers on Saturday or Saturday night. Rain chances are probably highest to the east of Interstate 45, and even then are probably 30 percent or less. But it’s the most meaningful chance of rain we’re likely to see during at least the next 10 days, so it’s worth mentioning.

Next week

There’s not really much to suggest that our overall pattern will change much over the next 10 days, or longer. It will feel more like mid-June than mid-May, with temperatures generally in the low 90s. Summer, it seems, has decided to come early. Our luck.

  1. I understand this is hard to predict, does this look like a “death ridge” you? Or this is just a phase and we can resume to our typical hot afternoons followed by sea breeze storms to cool us off a bit?

    I fear that heading into this summer with severe drought conditions, this could indicate what you see is what you get, we may not see a drop of rain for the next 4 months.

    • I know what you mean, I fear a repeat of 2011, when that high pressure ridge was basically stuck over the state of Texas for months at a time. We’re actually somewhat fortunate compared to the rest of the state westward right now. My unqualified expert opinion is that it won’t be quite as bad as 2011 and we’ll get a pattern change at some point this summer. Still, its looking like a long hot dry streak in the foreseeable future with many triple digit days ahead.

      • Brutha Anthony, I’m with ya. Please let this not be 2011……. The Rematch.

  2. You say Summer begins on June First;
    I say Summer begins on June Twenty-First…..

    • Meteorological summer vs astronomical summer… Both of you are right, but given the subject of this webpage, edge goes to Eric.

  3. Extreme drought!
    Road trip thru New Mexico wow never seen anything like it.Dirt front yards,burn bans everywhere.Amazing

    • The winds here in NM have been sustained between 25 to 35 with gust to 60 for days. There will likely be no relief until the monsoons start in late June or early July. Wish we were closer to a big body of water, that can be the game changer.

  4. This is awful already, I’m not looking forward to our hottest months of the year (August/September)
