Dog’s breath weather descends upon Houston now

Posted by Eric Berger at 6:55 AM

One of my favorite sayings about Houston’s weather comes from Bill Read, a long-time meteorologist in charge of the National Weather Service’s office in League City, who later served as director of the National Hurricane Center from 2008 to 2012. He characterized the morning humidity in Houston, during the summer, as “dog’s breath weather.” And with low temperatures only around 80 degrees this week, and dewpoints in the upper 70s, it will definitely feel like a dog breathing on your face in Houston for the time being. Other than that, there’s not much to say about Houston’s weather in the days ahead. It’s gonna be hot and humid.

Atmospheric moisture levels remain fairly high today, but with high pressure building in it will be difficult for that surface moisture to rise and produce rain showers. So while we’ll definitely see some clouds today, I think rain showers will be isolated at best. Highs should reach into the low- to mid-90s with lots of that aforementioned humidity.

Thursday and Friday

Hot and sunny. Need we say more? OK. Highs in the low- to mid-90s. Find some shade.

Houston has had a moderate first half of July, with an average high temperature below 93 degrees, and overall temperatures slightly below normal for this time of year. That is now about to change, as we shift into the mid- and upper-90s, virtually no chance of rain, and full-on summer. We hope you like it hot, because hot is what you’re going to get.


Remember all those clouds and healthy rain chances last week? Yeah, they’re pretty much gone. During most of last week the amount of moisture in the atmosphere, typically measured as precipitable water, was quite high as we saw values 50 to 100 percent above normal for this time of year. But this morning the tables have turned, with precipitable water values only about 50 to 70 percent of normal levels.

So rain chances are going to go way down today, and go pretty much away for quite a while. Skies today should be partly sunny with highs in the mid-90s. What you probably will notice is a fine, yellow haze. That’s the Saharan dust that will be with us for the next few days. It will at least make for some pretty sunsets.

Heat and minimal rain chances through the weekend

Posted by Matt Lanza at 6:37 AM

Good morning. Yesterday was the 16th day this month that we officially hit 95° or hotter in Houston. The last time we did that was 2013. At least this isn’t a repeat of 2011, when we did 95+ on 26 occasions. We will continue to flirt with 95 degrees for the final three days of June. More on that in a second. Below today’s forecast, we’ve got some analysis on the National Weather Service post-Harvey service assessment that was released last week. I farmed out some interesting tidbits for you that may be of interest. First, the forecast.

Today & Friday

More hot weather is in store for us over the next couple days. We had a handful of showers in the region yesterday, and we’ll probably have a handful more today. However, atmospheric moisture looks a bit more robust today than it did yesterday, so that should yield a slightly larger handful of showers than Wednesday. That said, we’re talking like 20 percent chances at best here. Basically, if you see a cooling shower today or tomorrow, consider yourself fortunate.

Temperatures will peak around the middle 90s once again both Thursday and Friday.


Shower chances continue to look like they’ll dwindle to near zero this weekend. With that, expect more hot weather. Officially, high temperatures should reach the mid-90s both Saturday and Sunday. Take it easy outdoors, as it will continue to be quite humid and uncomfortable.

As noted yesterday, we will also be dealing with Saharan dust. Skies will be hazy or gray looking at times, despite sunshine. And again, if you have any respiratory ailments or bad allergies, you may want to take it a little extra easy this weekend, as air quality could be a little worse than usual.

Just to clarify, as we’ve gotten a handful of interesting questions, this isn’t a dust storm or big, unique event for us. This happens at least a few times a summer usually. The vast majority of us will notice more haze than usual and the color difference to the sky. Maybe, if we’re lucky, the sunsets and sunrises will be more vibrant, though I’m happy to put a Texas sunrise or sunset up against anyone’s on a normal day. Sometimes, too much dust can have the opposite effect and dull the sunsets or sunrises a bit.

The only real “impact,” per se, is the slight increase in particulate matter, which is why if you have bad allergies or other respiratory ailments, we encourage you to take it easy. It’s certainly meteorologically interesting and a nice reminder of how fascinating this marble is that we inhabit to realize that you’re seeing dust in the sky in Texas that’s come all the way from Africa.

Next week

We do still look to be on track for a change next week, though the details are very uncertain. We’ve got high confidence in Monday still looking a lot like the weekend, with some haze and plenty of heat and humidity. By Tuesday, a disturbance aloft will be approaching western Louisiana, perhaps generating slightly better storm chances east of Houston toward Beaumont or Lake Charles. After about Tuesday afternoon, forecast confidence trends downward. Wednesday will probably see our storm chances peak in the Houston area and just east, but depending on the speed and trajectory of next week’s disturbance, that could easily get pushed back to Thursday.

So before you go cancelling any plans, just know that as of right now we don’t expect a washout on the Fourth of July yet, just a better than average chance of storms. That said, yes, if you have outdoor plans you want to stay tuned to the forecast, as this could shift one way or another pretty easily. More on this tomorrow.

A lot of stuff to get to today. We’ll go through the forecast first, and then jump into the National Hurricane Center’s final report on Hurricane Harvey, released yesterday.

Today & Saturday

We’re thinking today will be a rather uneventful weather day. We should see a good deal of cloud cover around, with limited (if any) sunshine. Temperatures are starting the day much warmer (around 50° in most spots, roughly 15° milder than yesterday at this time), and they’ll likely finish warmer than yesterday too. We should manage about mid-60s this afternoon.

In terms of rain, the bulk of today should be dry, but there could be some sprinkles or showers.

Things do change tonight as onshore flow continues, driving in ample moisture. A weak disturbance passes offshore, and this combination will lead to increasing rain chances as the night goes on. The best chance for the most shower activity will be south and east of US-59. The general rule of thumb will be that the closer to the coast you get, the better rain chances will be. Saturday will see shower chances continue in the region, but I think they’ll be highest both in the early morning and later afternoon. And once again, they’ll be highest south and east of Houston. Still, have an umbrella handy Saturday. It will be warm again, with highs near 70 degrees.

Total rainfall tonight and tomorrow will be highest well south and east of Houston. (Weather Bell/WPC)

Generally, we’re only expecting about a half inch or less in and around Houston. Some coastal locations could see upwards of three-quarters of an inch or so of rain. Higher amounts will be possible as you move toward Beaumont-Port Arthur and Lake Charles. Also, watch for some patchy dense fog along the coast (or even in some inland spots) later today through Saturday night.

Sunday into next week

A cold front will pass through the area Saturday night without much punch. You’ll notice it more Sunday with lowering humidity and gradually decreasing clouds. Expect temperatures to top off near 65° or so on Sunday. Sunday night will be chilly, with lows back into the 40s in the area. Monday and Tuesday continue to look splendid, with highs in the low-60s and lows in the 40s. We’ll see a warm up with increasing clouds and minor rain chances after Wednesday.
