After a fairly active start, the end of Labor Day weekend should be quieter

In brief: Happy Labor Day! This is just a short update due to the holiday, and in reality there’s not too much to say. After fairly widespread showers and thunderstorms on Saturday and Sunday, today should see less activity.

Labor Day

Although Tropical Storm Edouard largely missed the metro Houston area in terms of rainfall, an unsettled pattern in its wake has generally brought 1 to 3 inches since then. Much of this rain has come over the holiday weekend. The rain was welcome to be sure, but did it have to come when most people were off work and school?

For those seeking to do outdoor activities, some solace and sunshine should come today. Rain chances will drop back to around 20 or 30 percent for most of the region, with only areas near and along the coast seeing slightly better odds for precipitation. Skies, otherwise, should be mostly sunny with high temperatures in the low- to mid-90s for most of the region. Winds will be light, from the south. Lows tonight will drop into the upper 70s for most of Houston area.

It’s still going to be warm this week, but we’re likely done with triple-digit highs. (Weather Bell)

The rest of this week

Tuesday looks hot and sunny, whereas a surge of tropical moisture could bring some more widespread showers into the region later on Tuesday evening or Wednesday. The remainder of the week, and next weekend, should see mostly sunny days, highs in the low- to mid-90s, and low-ish afternoon rain chances along the sea breeze. It will feel very much like early to mid-September. We won’t see a cold front this week, but I’m not entirely ruling something out about 12 to 14 days from now as we get deeper into the month. More on that tomorrow.

Have a wonderful holiday and we’ll be back with a full report on Tuesday.

Labor Day weekend storm chances tick up for Houston on Saturday before a mostly typical September week

In brief: Houston’s storm pattern may tick up a little on Saturday as the Gulf opens the doors a little wider. But Sunday, Labor Day, and most of next week should feature very typical September weather for the Houston area.

Back to regularly scheduled summer in Houston, as we return to a more standard early September pattern of daily storm chances, moderate heat, and, of course, humidity. Let’s check in on how the region fared over the Tuesday-Wednesday-Thursday period for rainfall.

If you were lucky, you saw a cooling downpour or two. If you weren’t, well, we apologize. But most of the area at least saw a little rain, and while that may not erode developing drought concerns, hopefully some additional rains fall the next few days. But also note how close it was to being a much, much different story.

Today

We’ve already got a number of showers peppering the radar this morning. Most gauges have only seen a few hundredths of an inch of rain, but some spots should see more over the next few hours. We may see a bit of a lull around late morning and then more scattered showers and storms this afternoon. Highs should still manage to make the lower 90s this afternoon.

Saturday

Tomorrow will be a slightly more interesting day on the storm chance front. Edouard’s remnant “spin” will shift southwest of the area toward South Texas, which should open up a slightly stronger “fetch” off the Gulf. This, coupled with some upper level impulses probably upgrades our coverage of thunderstorms tomorrow afternoon. If today is isolated to scattered, tomorrow is more like scattered to numerous in terms of coverage. Or that’s what I think looking at things this morning.

The probability of an area seeing at least 1 inch of rain tomorrow on the REFS model is highest just east of Houston and near Matagorda Bay, but it remains high elsewhere around Houston. (WeatherFront)

Any downpours will be capable of producing torrential rainfall, so watch for some localized street flooding. Highs may reach the low 90s, but if storms get going a little sooner, we may only get to around 90 degrees.

Sunday

Edouard’s remnants are gone gone on Sunday. This should allow us to dial back storm coverage a bit, back to the isolated to scattered bucket. Highs should be back in the low 90s.

Next week

I don’t foresee a ton of variability next week as it stands right now. Labor Day should be a lot like Sunday I think, with isolated to scattered afternoon thunderstorms. Tuesday, Wednesday, and Thursday look fairly similar. Each day should feature the requisite mixture of clouds and sun, with highs in the low to perhaps middle 90s.

The good news is that the tropics are on holiday right now, something I discussed over at The Eyewall last evening. Let’s keep it going.

An unsettled pattern will bring showers and thunderstorms into the region for the next few days

In brief: The remnants of Tropical Storm Edouard have traversed north of our region, but it has left a disturbed atmosphere in its wake. This should lead to healthy shower and thunderstorm chances in the coming days, and slightly cooler than normal temperatures.

Edouard gone, but an unsettled pattern remains

The remnants of Edouard have now moved over north Texas, with heavy rains lingering in places like Huntsville and Crockett this morning. While this system will continue to slowly progress north today, it will leave an unsettled pattern in its wake over Houston. This essentially means that there is plenty of atmospheric moisture and low pressure, conditions capable of producing showers and thunderstorms.

Atmospheric moisture levels this morning are 130 to 150 percent of normal. (Weather Bell)

We saw the effect of this on Wednesday, when there were some fairly robust thunderstorms in northern Harris and southern Montgomery counties, including in The Woodlands. This pattern will persist into the weekend, bringing heathy rain chances to our region. Afternoon heat will provide the best opportunity for storms to form, but showers won’t occur exclusively during the afternoon and early evening hours. Over the next three days I expect most of Houston to pick up between 0.5 to 1 inch of rain, but of course there will be some areas that get more (beneath stronger cells) and some locations that miss out completely.

Thursday and Friday

Both of these days will see, as mentioned above, healthy chances of afternoon or early evening thunderstorms. I’d put chances at around 50 percent for most of the area. With mostly cloudy skies, we should see highs max out at around 90 degrees, or slightly above, for most locations. Rain chances should slacken overnight, but not completely go away. Overnight lows will fall into the upper 70s.

Saturday

This will be another day with ample moisture, so similar to Thursday and Friday I expect a healthy chance of afternoon showers and thunderstorms. Not everyone will get hit, of course, and the way it usually works in Houston is if you’re desperate for rain it’s dry, whereas two neighborhoods over it’s raining cats and dogs. Highs should peak in the low 90s.

NOAA rain accumulation forecast for now through Saturday: most of the area gets 0.5 to 1 inch, with the usual variations. (Weather Bell)

Sunday and Monday

Sunday could go either way, as in it could see widespread showers and mostly cloudy skies, or we could start to see the influence of high pressure so conditions start to clear out and temperatures warm into the low- to mid-90s. I do expect that by Labor Day most of the region will be mostly sunny, with a lower likelihood of rain and weather that’s a bit warmer. Hopefully we can get you a more precise holiday weekend forecast in tomorrow’s post.

Next week

My general expectations for next week are a continued pattern in which we see partly to mostly sunny skies, highs in the lower 90s, and decent-to-good rain chances during the afternoon hours. We are unlikely to see a dominant ridge of high pressure develop again, as happened in August, so that should keep us open to the possibility of sea breeze showers.

Major flooding occurring over East Texas; Houston region to see decent rain chances as Edouard pulls away

In brief: In today’s post we discuss the very heavy rainfall from Edouard that occurred overnight over East Texas. We also look ahead to a warm, but not too warm period for the Houston metro area during which we will continue to see some decent daily rain chances. (Yes, really).

The remnants of Tropical Storm Edouard are slowly moving to the north-northwest this morning, and rains near the center have produced significant flooding over counties to the northeast of Houston, particularly Polk and Hardin counties. Some towns north of Beaumont, including Kountze, Saratoga, and Lumberton, have received in excess of 12 inches of rainfall. Closer to Houston, locations such as Conroe, Cleveland, and Dayton have all seen several inches of rainfall.

These rains should slowly lift north today, into Walker, Trinity, and Houston (note: Houston County lies well to the north of the city of Houston) counties along with the remnants of Edouard. An additional 3 to 6 inches of rain is possible in these counties from the slow-moving system. Strong winds have also been observed near the center of the system, with gusts in the 40s recorded near Lake Livingston. But these are now fading.

Let’s take a look at the forecast for the Houston metro area.

Wednesday

Although Edouard proved a major disappointment on the rainfall front in Houston, its passage does not spell the end of our rain chances. It leaves in its wake a fair amount of atmospheric moisture, and this should produce a healthy likelihood of showers later today. Much of the area has about a 50 percent chance of rain, most likely during the afternoon hours with peak heating. Some locations may pick up as much as an inch, while other areas will miss out. Speaking of daytime heating, highs today will reach the lower 90s for most locations, with partly to mostly cloudy skies. Winds will be from the southwest at 5 to 10 mph.

Houston’s temperatures will be normal for the next week or so. (Weather Bell)

Thursday, Friday, Saturday, and Sunday

A similar pattern will persist into Labor Day weekend. We should see a mix of sunshine and clouds during this period, with most of Houston recording highs in the low- to mid-90s, which is fairly standard for this time of year. Each day is likely to have about a 50 percent chance of rain. Some of the short-range models are fairly bullish about shower chances on Thursday, but I want to see more data before I bite. By the weekend I do not expect widespread or long-lived showers, but they could still pop up at your pool or beach day.

Labor Day and beyond

If I had to guess—and I’m a meteorologist, so I guess I must—I would say that Labor Day will be a fairly sunny, low-rain chance kind of day. Expect widespread highs in the low- to mid-90s probably, so beaches and barbecues and the like will probably find favorable weather. There’s not a clear signal for what is coming later next week, but overall I do favor the return of healthy daily rain chances by Tuesday or Wednesday. So despite our disappointment at not seeing some rain from Edouard after a very dry August, I believe the overall pattern ahead of us favors a wetter pattern over the next 10 days.
