How bad is August weather in Houston? ‘Mere anarchy is loosed upon the world’

In brief: In today’s post we look at how bad August really is in Houston, and fall back on a little post-war poetry for assistance. With regard to the forecast, we’ll be blistering hot for the next couple of days before conditions cool off slightly.

Look at those record highs: August is a brutal month. (National Weather Service)

August

This is the month of no respite. This is the month, often, of no rain. This is the month of relentless heat and humidity.

This is, quite simply, the worst month of the year in Houston.

How bad is it? In the aftermath of World War I, the Irish poet W.B Yeats wrote The Second Coming about the world sliding into chaos and collapse. It is a dark and haunting poem, and I sometimes think of it when contemplating August in Houston. These lines in particular:

Things fall apart; the centre cannot hold;

Mere anarchy is loosed upon the world,

The blood-dimmed tide is loosed, and everywhere   

The ceremony of innocence is drowned;

That is how I feel about August. It is the hottest month of the year, with the warmest days and muggiest nights melting all into a blood-dimmed tide. It also, historically, is when the plurality of hurricanes strike Texas (September ranks second). We often fall into miserable droughts. And by this time of year we have already gone through June and July; a steady progression of ever hotter days, a seemingly endless march toward the realm of Hades. Mere anarchy, indeed, is loosed upon our metro area’s atmosphere.

The good news—and let’s be honest, good news is in short supply at the moment—is that nothing lasts forever. We are already on August 3, and 6.5 percent of the month is behind us. Fall is not right around the corner, but it does lie on the horizon. Plausibly we could see the region’s first front in six weeks or so. And in the more near term our weather later this week should see a slight downturn in temperatures. We celebrate these small wins in August, because that’s all we can hope for.

Monday

You may not have noticed it, but a weak front moved in to Houston on Saturday. Dewpoints on Sunday briefly dropped below 65 degrees in some locations, particularly north of Interstate 10. Although air temperatures were still in the upper 90s, the air was a smidge drier. There may be a similar, less pronounced, effect this afternoon. This slightly drier air will allow inland temperatures to once again push up near, or reach 100 degrees this afternoon before the sea breeze completely washes the drier air away. Areas near the coast will be a bit cooler this afternoon, but more humid. There will be about a 10 percent chance of showers this afternoon or evening. Lows tonight will be around 80 degrees, so very sultry.

Tuesday and Wednesday

These will be hot, humid, and sunny days with highs in the upper 90s (perhaps 100 degrees for far inland areas). We cannot rule out some isolated to scattered afternoon showers, but chances are probably only in the 10 or 20 percent range. Nights remain sultry.

There is some slightly cooler weather ahead of us. (Weather Bell)

Thursday through Sunday

Although we’ll remain in the midst of fairly high pressure, we should see a more pronounced onshore flow during the second half of this week, and into the weekend. The effect of this will likely be to increase cloud cover (from mostly sunny to partly sunny, probably) and bump up daily rain chances to 30 or 40 percent. In turn, this should help bring down daily highs from the upper 90s to the mid-90s, or likely lower-90s for coastal areas. In terms of rain accumulations I would not expect too much in this pattern, but some passing showers would be generally welcome after a fairly dry period over the last few weeks. Anyway, as August goes, things could definitely be worse.

Next week

Speaking of worse, indications are that our pattern flips back to sunnier and hotter next week. But again, this entire month is about surviving and advancing, at least when it comes to weather. At least the tropics look quiet for now.

Houston’s sunny, hot weather continues with only a single mystery: What happens with a weak front this weekend?

In brief: Houston’s sunny and hot weather continues, but we’re watching for modest impacts from a dying front on Saturday or Saturday night. Rain chances from this front are not great, but they’re the best we’ve seen in awhile around here.

Overview

High pressure will dominate for a few more days before a weak front squeezes into Texas on Saturday or Saturday night. This will bring us a brief shot at some showers (and possibly a thunderstorm or two, but probably not), and possibly a few hours of slightly lower humidity. The timing of the front is important here. Following this we’ll be back to hot and sunny weather for the majority of next week, although temperatures might be 1 or 2 degrees cooler than this week. Maybe. It’s gonna be August so you know it will be miserable.

High temperatures today will be 4 to 6 degrees above normal for most of the region. (Weather Bell)

Friday

Today will be like the rest of this week so far: highs in the upper 90s to 100 degrees, sunny, humid, and hot. Light winds this morning will turn gusty later this afternoon and into the evening hours. Lows remain sultry, only dropping to around 80 degrees or slightly below.

Saturday

Weakening high pressure will allow a front to slip into Texas on Friday and Saturday, and by Saturday afternoon or evening it should approach the greater Houston area. The timing is important, because if the front reaches the metro area during the afternoon or early evening there will be plenty of heat for it to help generate some showers and thunderstorms. If not, then there will be less coverage. For now let’s go with rain chances in the vicinity of 30 percent during the period of Saturday afternoon through the overnight hours. Aside from this, Saturday is still going to be hot, sunny, and humid.

Sunday and Monday

These will be hot days with highs in the vicinity of 100 degrees. The wrinkle is that our air mass might be slightly less humid due to the front’s arrival. Not knock-your-socks-off lower humidity, but the kind of thing you may be able to feel on Sunday morning or evening. Or not. Rain chances both days are near zero.

Highs may come down a couple of degrees next week. (Weather Bell)

Next week

Houston’s weather turns slightly more normal-ish for August next week, with highs in the mid-90s to upper-90s most likely, and perhaps a 10 or 20 percent chance of afternoon showers. In general, this is pretty miserable. But because this is August, it’s pretty much the norm around these parts.

Have a wonderful weekend, everyone. We’ll see you on Monday morning.

Heat continues, with a slight chance of rain showers this weekend

In brief: In today’s post we discuss high pressure, and what impacts the region might see from a weak front that will move in from the northeast this weekend. Also, August looms.

The only cool air in Texas this morning can be found on a few peaks in the Davis Mountains in West Texas. (Weather Bell)

Big picture overview

High pressure continues to dominate our region’s weather, and it will do so for the rest of the work week. By this weekend high pressure will slowly ease westward, allowing a weak front to drop into East Texas. Since we are literally in the dead of summer, this front likely will not bring too much in the way of meaningful relief to our humid air mass. However it could spark a chance of showers later on Saturday, Saturday night, or Sunday. These would be briefly lived. High pressure likely returns next week, bringing more high summer heat along with it.

Thursday, Friday, and Saturday

If you liked the weather the past couple of days you’re in luck, because that’s more or less in store for the next three days. We can expect highs in the upper 90s to the low 100s, with sunshine and ample humidity. Light south winds will become a bit gusty during the afternoon hours. Rain chances? Maybe 10 percent daily, although by Saturday evening or Saturday night they may bump up to around 30 percent given the backdoor front mentioned above.

NOAA rain accumulation forecast for now through the weekend. Set your expectations accordingly. (Weather Bell)

Sunday

Skies will again be mostly sunny and hot. However we may well see some scattered showers and a few thunderstorms associated with the backdoor front during the daytime. The other thing I’m watching for is the potential for slightly lower dewpoints, in the 60s. If this were to happen it probably would be in the Sunday morning to Sunday evening time frame, for areas north of Interstate 10. The lower humidity effect would be very modest, but potentially noticeable. No promises.

Next week

Next week’s weather looks a lot like this week’s: Very hot, humid, and sunny. Possibly some increased rain chances toward the end of next week. Possibly.

Houston’s weather is hot, hot, hot. The Atlantic tropics are not, not, not.

In brief: In today’s post we discuss the quietude in the Atlantic tropics, and when that could begin to change. Also, our heat continues for as far as the eye can see, although there are some slight rain chances out there.

A quick look at the Atlantic

Nearly a week after Tropical Storm Bertha moved into Texas the overall picture in the Atlantic tropics remains very quiet. It is possible that a weak system forms off the Eastern Seaboard of the United States next week, but it likely would be moving away from land. The Gulf and Caribbean remain very quiet, and this is due in part to rather high wind shear levels across these basins.

Overall, things look good for the next couple of weeks, which is about how long we can reasonably expect to forecast out. It will be about that time, August 10 or so, that historically the Atlantic tropics start to take off. This is the point in the season when tropical waves start to move off the West African coast into the Atlantic, and strengthen into tropical storms and hurricanes as they propagate westward across the ocean in what is known as the “main development region.”

You can see this burst in activity in the above plot of “accumulated cyclone energy,” which starts to spike later in August and activity remains high into early October. This year (note the red line) activity is significantly below normal, just 34 percent of a typical total. That’s a great start, and to be clear we expect an overall fairly quiet season given a strengthening El Niño, but the bulk of this season lies ahead. We will need to get through August and most of September before giving an all clear for the year in Texas.

Wednesday

The high temperature at Bush Intercontinental Airport reached 97 degrees on Tuesday, and that should be the region’s coolest day for awhile. Highs today will probably reach around 100 degrees, with plenty of humidity and mostly clear skies. Of (slight) note there is about a 10 percent chance of showers or isolated thunderstorms this afternoon due to a potential break in the capping inversion. Winds pick up out of the south later this afternoon. Lows tonight will be around 80, or just below.

Thursday through the weekend

Our hot weather continues. Expect highs in the vicinity of 100 degrees, or the low 100s, for most of the Houston region away from the coast. Near the Gulf waters, highs will be a few degrees cooler. The models continue to indicate a decent chance of rain on Saturday night or Sunday, perhaps 30 percent. Is this a mirage? We’ll see. But mostly we’re going to be sunny and hot.

Next week? Yeah, it’s going to be hot too. (Pivotal Weather)

Next week

For now, I’m leaning toward the “not much changes next week” scenario. Welcome to high summer, y’all.
