Houston will see peak heating the next couple of days—with nearly all of the region experiencing triple digit temperatures away from the immediate coast—before a dominant high pressure system starts to progress eastward. This should slowly start a return to somewhat more normal weather, which is to say by the middle of next week we could be in the mid-90s, with decent rain chances.

Wednesday

An excessive heat warning is in effect for inland counties today, including the cities of Crockett, Madisonville, Huntsville, Caldwell, College Station, Bryan, Brenham, and Navasota. This means these areas could see high temperatures of 105 degrees or above, with dangerous heat levels due to humidity. The rest of the region should see highs of around 100 degrees, or a bit higher, with only the coast remaining in the 90s. Skies will be sunny, with southerly winds at 5 to 10 mph, and higher gusts. Lows tonight will not drop below 80 degrees.

Thursday

Another brutally hot day, similar to Wednesday.

Friday

By Friday the high pressure system should start to back off a little bit, and this should open up the potential for a few isolated to scattered coastal showers. However, I don’t expect these rains to make it past Interstate 10. Most of the region should otherwise see mostly sunny skies, with highs in the upper 90s.

Saturday and Sunday

The weekend should bring highs in the upper-90s for much of the region, with mostly sunny skies and only slight 10 to 20 percent rain chances.

Next week

After starting in the upper 90s, temperatures will be slow to come down next week. But by Wednesday or Thursday we could start to drop back toward the mid-90s, and with a few more clouds begin to see the more widespread development of showers and thunderstorms. For now I’d guess rain chances most days will be in the 30 percent range, but there’s just no way to tell with much precision at this point. The bottom line is that the next six or seven days look pretty dry, in terms of rainfall, but there is least some potential for change after that point.

Good morning. There’s not much good to say about our weather for the next several days, outside of the fact that at least we won’t see flooding or the winds howling. However, after three or four really hot days of triple-digit temperatures, I do think we’ll see a slight downturn in highs, and an uptick in rain chances. The effect is likely to be subtle, but any relief is better than no relief, right?

Tuesday

Monday’s high temperature reached 100 degrees at Bush Intercontinental Airport, and we can probably expect today to be a carbon copy with mostly sunny skies. Winds will be out of the south, at 10 mph or so, with gusts up to 15 or 20 mph. Lows tonight probably won’t drop below 80 degrees for most of the region.

Wednesday and Thursday

It looks like the heat will peak on these days, with highs ranging from 100 to the low 100s for much of the area away from the coast. Expect sunny skies and southern winds. You should know the drill by now.

Friday, Saturday, and Sunday

It’s still going to be hot, but highs at some point should start to drop back into the upper 90s. We’ll also see a somewhat more disturbed atmosphere that should allow for the development of at least some isolated showers and thunderstorms. Expect mostly sunny skies.

Next week

Overall, the pattern won’t change a whole lot. But I think we’ll see highs in the mid- to upper-90s, instead of around 100 degrees. And rain chances will continue to be non-zero, but at this point it’s difficult to say whether we’re talking about 10 to 20 percent chances each day, or the more hopeful 30 to 40 percent.

Good morning. I wanted nothing more than to start this week by writing a hopeful post about Houston’s forthcoming weather—to say something about cooler weather ahead, more moderate nights, or a few days of steady rainfall and cloudy days. Alas, this is a reality-based site, and I’m sorry to say the rest of July looks very sunny, very hot, and mostly rain free.

Before jumping into the forecast, dreadful though it may be, I wanted to provide a situational update on our 100 degree days this year. These are officially recorded at Bush Intercontinental Airport, which is the city’s official monitoring station. Through Sunday, the city has now recorded 14 such days, which places this year second only to 1980 in terms of accumulation through July 17. Matt has been tracking these dates, and prepared the line chart below to show how this year (black line) compares to to most summers. Of note are years 1980 (Blue) and 2011 (pink).

Monday

High pressure is back, and it will be the dominant factor in our weather for the week ahead. This means mostly sunny skies for today, with highs near or above 100 degrees for inland areas, with highs in the low- to mid-90s near the coast. Winds will be light, out of the south or southwest at 5 to 10 mph. Lows will be sultry, only dropping to about 80 degrees in Houston. Rain chances are 10 percent or less, due to a capping inversion that is helping to prevent air at the surface from rising.

Tuesday

Rinse and repeat, although there will be precious little rinsing due to a lack of rain.

Wednesday and Thursday

Both of these days will be sunny, and perhaps a degree or two warmer as the high really takes hold.

Friday

Some sort of weak disturbance may attempt to pass over the area toward the end of the week, and this could bump up our rain chances to about 20 or possibly even 30 percent. It ain’t much, but it’s probably the best we’ll see this week.

Saturday and Sunday

These should be mostly sunny days, with highs of around 100 degrees. Rain chances at this point don’t look to be zero, but they are less than 20 percent.

Next week

If you’re looking to the extended forecast with some hope of a pattern change, I would say two things. First of all, congratulations on being an optimist. The worlds needs more of you. The second thing I would say is to remind you that August begins in 13 days.

Good morning. We’ve seen a healthy line of thunderstorms move through coastal areas this morning, including a pretty good soaking for the city of Galveston. As I write this the rain-cooled temperature is 77 degrees on the island. According to the National Weather Service, this is the first time the temperature there has dropped below 83 degrees, since July 1. I’m hopeful that other parts of the metro Houston area will see some welcome showers today and on Friday before heat and high pressure return this weekend.

Thursday

Skies will be partly sunny today as atmospheric moisture levels increase, and high pressure remains just far enough to our northwest to allow clouds to form. Showers and thunderstorms will become increasingly likely this afternoon, with storms moving from northeast to southwest. Local temperatures will depend a lot on the extent of this cloud cover later today, and whether you see showers this afternoon and evening. Overall, I expect areas south of 1-10 to stay in the low- to mid-90s, with inland areas likely seeing the upper 90s, and some locations such as College Station probably pushing to 100 degrees.

Rain chances are about 40 percent, and these showers will be hit or miss, with briefly intense rains possible and straight-line winds within thunderstorms. Storm chances will slacken overnight. Winds will be light, mostly out of the southeast.

Friday

I expect Friday to be similar to Thursday, albeit with probably the better chance of rain closer to the coast. This day probably is our region’s best chance to see a high temperature of 95 degrees or lower since July 1, and also probably our best chance of doing so for at least the next week or 10 days.

Saturday and Sunday

The weekend should see a return to high temperatures in the upper 90s for much of the region, with far inland areas possibly hitting 100 degrees. These days will be mostly sunny, although we probably will have about a 20 percent chance of an afternoon shower.

Next week

Unfortunately it appears as though high pressure will continue to build back over the area next week, pushing area-wide highs toward 100 degrees again, and rain chances below 20 percent each day. If you’re wondering when this pattern will break, I’m not sure I have a great answer. Instead, I have a depressing one—we still have our warmest month to come, August, when these ridges are often at their thickest. I hope you see some precipitation today.
