Good morning. It has been a long, very hot, and mostly dry summer for Houston. For the next three or four days, however, we’re going to see a distinct pattern shift amid a weakness in the high pressure ridge that has dominated conditions since late May. This weakness, combined with a surge of tropical moisture, will bring healthy rain chances from now through Saturday, and should also knock high temperatures back several degrees. It won’t rain all of the time, but it should rain some of the time. Sunny and hotter weather returns early next week.
Skies will be partly sunny today, starting out like most recent days. Highs should climb into the mid-90s for much of the region, with the usual smattering of coastal showers and thunderstorms. The more significant change comes this evening, as what is essentially a dying front moves southward into the region. At some point around sunset, give or take a couple of hours, we should see a broken line of storms moving from north-northeast to south-southwest across the area. It is not entirely clear whether these storms will hit western or eastern parts of the metro area hardest, but expect a healthy chance of showers and thunderstorms between 4pm and midnight. The strongest of these storms will produce heavy rainfall, with damaging winds. Low-lying streets may briefly flood in the heaviest storms.
Skies should be partly to mostly cloudy on Thursday, helping to limit high temperatures to the low 90s. Atmospheric conditions will continue to be favorable for rainfall, with chances of 60 or 70 percent for much of the area. Again, we expect showers to be hit or miss. Overall chances are probably better closer to the coast, and east of Interstate 45.
Friday and Saturday
This generally cloudier and potentially rainier pattern should persist into the first half of the weekend. Both of these days should see a mix of clouds and sunshine, with highs perhaps reaching 90 degrees, or slightly above. Rain chances both days are 50 percent, or perhaps even higher. All told, much of the region probably will pick up 0.5 to 2 inches of rain through Saturday, although some areas will see more, and alas, others less.
Sunday and beyond
By Sunday we should start to see the influence of high pressure again, as skies become sunnier and rain chances start to slacken. By the middle of next week temperatures should climb to the mid- to upper-90s, and it will be plenty hot. However, the potential for rainfall may return toward the end of next week, providing us some additional relief. We shall see.

Please remove the umbrella over Cypress!
We need hurricane!
You must be new to Houston. Welcome! Here’s a tip to help you have a good experience living in our city: Never Ever, Under Any Circumstances, wish for a hurricane.
I second that! Yes hurricanes are terrible. Rather a hot and dry summer than a hurricane.
We definitely don’t. I wouldn’t mind a tropical wave or something like that, but definitely not a tropical storm (unless it moves through quick) or a hurricane.
I agree Thiyagarajan in the sense we need a big storm. I have lived here for a few decades and while I don’t think we need a hurricane, don’t need the rain, we need a depression or tropical storm. Definitely need the rain especially since the long term forecast is showing a dry fall for us as well.
Nobody in here is gonna agree with you about your tropical storm idea, just stop
I think it’s a great idea, if it’s scaled way down. 😂
For my uneducated prediction, I’m going to go ahead and say that any rain we see will be mostly east of downtown. Things are really in a bad way here out on the west side and Katy areas.
With a certain amount of hesitation due to previous nearly disastrous results of wanting it to rain, I say, rather, whisper:
Kudos Eric, you totally nailed today’s forecast! (Also, my rain gauge has been dry for so long it broke at 0.18″)
I think plenty around Houston will be happy with the soaking we just got, at least for a while.
was pretty cool to watch the eastern storms outflow this evening cause that brief rotation over the western storm @ Katy today. You coud see it coming on radarscope. classic. Buddy of mine got a pretty good .gif of it.
So … share it (the .gif, i mean)
It would have been nice to get a soaking rain. One that diverts planes makes life interesting and adventurous! Hello Midland!
