Good morning. I would love nothing more than to report some positive news about the Houston weather this morning. To say that temperatures are going to drop back into the low 90s next week, with a decent amount of cloud cover. Or to say that our region is finally going to get a good soaking from some much needed, steady rains. But I can say none of those things. For the next week or 10 days, unfortunately, it looks as though our weather is just going to get hotter, and anyone getting some rain will feel like they hit the lottery.

Thursday and Friday

High temperatures today and Friday will reach the mid- to upper-90s for much of the region, with mostly sunny skies. And if you’re thinking that sounds bad, well, this is actually our cooler stretch of weather before things really start to heat up this weekend. Winds will be light, out of the southeast. As for our rain chances, they’re going to be low. If you live north of Interstate 10, they’re about 10 percent or less. The highest rain chances will be south of Interstate 10, and particularly to the southwest in places like Fort Bend County. These may be about 20 or 25 percent. Again, if you receive any meaningful precipitation today or tomorrow, count yourself very lucky.

Saturday and Sunday

Houston will lie on the southern edge of a high pressure system anchored over the Central United States this weekend, but we’re going to feel its effects enough that we’ll see sunny skies and highs near 100 degrees this weekend. Rain chances are probably 10 percent, or less.

Next week

If you’re wondering whether there’s any relief in the forecast during the first half of next week, the answer is no. It’s going to be very hot, and at a minimum I would expect heat advisories from the National Weather Service, if not outright excessive heat warnings. It’s possible that rain chances rebound somewhat toward the second half of next week, but given the persistence of our heat and lack of precipitation, it’s hard to bet on that changing without a much stronger signal in the forecast models.

Good morning. Houston’s very hot, but not extremely hot, weather pattern will continue for the rest of this week, and well into next week. Truth be told, as we slide into August in a few days, this is the warmest time of the year in Houston. So we’re probably not going to see any significant relief, temperature-wise, for awhile. The best we can do is cloudier days with some rain-cooled air. There is a chance we may see a little bit more of that in a week or so.

Wednesday

This week we’ve seen a pattern of isolated-to-scattered showers and thunderstorms developing during the afternoon hours, most commonly south of Interstate 10, and this will continue today. Rain chances are about 30 percent for southern parts of Houston, and just 10 percent or so further inland. Otherwise we’re going to see highs in the mid- to upper-90s with mostly sunny skies. Winds will be light, from the south, and lows tonight will drop into the upper 70s.

Thursday

A day that will be a lot like Wednesday, except that rain chances will be just a bit lower.

Friday

Rain chances drop to about 10 percent area wide, as highs push into the upper 90s. Skies remain sunny.

Saturday and Sunday

High pressure will strengthen a bit over Texas this weekend, and this should lead to a pair of hot and sunny days with highs near or at 100 degrees. Rain chances both days will be on the order of 10 percent; which is to say very low.

Next week

The aforementioned high pressure system should start to retreat to the east next week, and this may open us up to the possibility of at least scattered showers, if not more widespread rainfall. To be clear, I’m not predicting any kind of washout. But we may get to the point where we’re seeing daily chances on the order of 40 percent by mid-week. Highs probably will remain in the mid- to upper-90s.

A combination of slightly cooler temperatures and slightly lower dewpoints means that the National Weather Service, for the first time in more than two weeks, has not issued a heat advisory or an excessive heat warning for today. These moderately cooler temperatures—mostly highs in the mid-90s instead of upper 90s to 100 degrees—will continue for the rest of the work week before nature’s thermostat rises again.

We can see this slight moderation in wet bulb globe temperatures, which we have been referencing during this summer’s heat wave. They will remain at high, but not extreme levels, until this weekend. One reason for the slight diminution in temperatures is the presence of Saharan dust in the atmosphere, roughly 1 to 3 miles above the surface. This reflects a bit of sunlight, decreasing the amount of energy reaching the ground. Unfortunately this increase in drier air may also wipe out chances for meaningful rainfall, which is badly needed.

Tuesday

Highs today will reach into the mid-90s for most of the region, with mostly sunny skies this afternoon. As we have experienced for a couple of days, rain chances will increase during the afternoon hours, particularly closer to the coast and along the sea breeze. However, I think chances will only be about 30 percent south of Interstate 10, and lesser for inland areas, partly due to the Saharan dust (levels of drier air make it more difficult for rain to reach the ground). Overnight lows may briefly drop into the upper 70s. Winds will be light, out of the south.

Wednesday, Thursday, and Friday

More typical, late-July-like conditions will continue through the end of the week, with highs in the mid-90s, and slight chances of rain along the afternoon sea breeze. If you’re looking for the “coolest” day in a while, that may be Thursday, when highs may not reach the mid-90s in parts of Houston, even away from the coast.

Saturday and Sunday

The weekend should bring us back into highs in the upper 90s, with coastal shower chances in the vicinity of 20 percent. So hot and sunny, for the most part.

Next week

This weekend and the early part of next week, truth be told, look pretty hot. I expect we may see another 100-degree day, or two. However, if I squint into the future I can see perhaps a return to slightly more moderate conditions by the middle of next week, with perhaps some healthier rain chances. That is part hope, and part science, however, as we’re talking about a forecast 7 to 10 days from now. As noted in the headline, don’t break out that sweater just yet.

Good morning. Houston remains on the edge of a high pressure system, so our weather this week will be slightly cooler than the last two weeks, with a puncher’s chance at some afternoon showers with daytime heating. The other factor to consider this week will be the influx of Saharan dust—dust kicked up over the large deserts in Africa and transported across the Atlantic Ocean by the atmospheric flow in the tropics. This dust will moderate temperatures slightly, but may also inhibit rain chances.

The net effect is that conditions will feel a bit more normal this week, and we can see this in the wet globe bulb temperatures we’ve been referencing. (These factor in temperature, clouds, winds, and humidity to provide a better overall sense of heat impacts). Previously this month we’ve see these temperatures reach extreme levels, but this week we should be more comfortably in the 80s. Which, don’t get me wrong, is hot. But not extremely so.

Monday

High temperatures today will likely top out in the mid- to upper-90s for most of the region, with mostly sunny skies. Showers and thunderstorms will be possible from early afternoon through early evening, primarily along the sea breeze. Rain chances today are probably in the neighborhood of 30 to 40 percent for areas south of Interstate 10, and 10 to 20 percent for areas for further inland. This pattern of better rain chance chances closer to the Gulf of Mexico is likely to persist for much of this week. Low temperatures will drop into the upper 70s tonight for much of the area, so slightly cooler than much of the rest of the month.

Tuesday through Friday

At this time there really is not much to differentiate the daily forecast for the remainder of this week. We are looking at daily highs, generally, in the upper 90s. Each day, primarily during the afternoon, we’re going to see a daily rain chance on the order of 20 to 30 percent close to the coast, with a lesser chances further inland. Winds will be light, from the south, and nights mostly clear.

The other factor this week is Saharan dust, which according to the latest modeling from NASA’s global modeling office should peak on Tuesday, Wednesday, and Thursday evenings. From time to time, Texas sees dust outbreaks from June through August. This layer of dust about 1 mile above the surface will bring dry air into the mid-levels of the atmosphere this week, and this may inhibit rain chances a bit. As this dust absorbs some sunlight, it should also help keep highs below 100 degrees. And finally, of course, it may lead to some rather vivid sunsets.

Saturday and Sunday

I have some questions about the pattern this weekend, as some modeling indicates a return to a very hot pattern in which high pressure prevails. However there is also a chance that our region stays just beyond this high pressure system. For now, I’m going to broad-brush things and say we’re looking at highs in the upper 90s with only a slight chance of rain.

Next week

Looking beyond the weekend, our weather next week probably will bring more of the same, in terms of mostly sunny skies and high temperatures in the upper 90s. At this point rain chances may turn slightly better later next week, but at that point my crystal ball starts to get pretty fuzzy.
