In brief: Following a period of rainy weather, a cool front, and some lower temperatures due to the passage of Hurricane Francine, Houston is going back into the mid-90s this weekend. Moreover, pretty much all of next week looks fairly hot and sunny. It won’t be August-hot, but after a taste of cooler temperatures it will be plenty hot.

The return of summer

It may be difficult to remember, but not all that long ago Houston recorded seven straight days of 100-degree temperatures. That period of peak summer ended 21 days ago. That’s when, during the last week of August, we started to transition into a rainy pattern, with high temperatures of around 90 degrees or below most days. Then we got our first fall front, and the passage of Hurricane Francine allowed the trend of cooler days to continue into this week.

As a result the Houston region has had about three weeks of cooler than normal days (nights have been more in line with climate normals, except for a few nights after the front). Well, I hope you’ve enjoyed it. Because high pressure is back, baby, and it’s bringing summer with it. We’re not returning to the days of 100-degree temperatures, but we are going to jump back into a period of substantially hotter days. I’m not sure when it will end.

Thursday

Today will be something of a transition day, with high temperatures of around 90 degrees or a bit higher. We should start out partly to mostly cloudy in the morning, but by afternoon we should see clearing skies and light northwest winds. Lows will drop into the lower 70s for most of the metro area.

Friday, Saturday, and Sunday

There won’t be much to distinguish these days. All three should see mostly sunny skies, with temperatures solidly in the mid-90s for most locations away from the coast. This is fairly warm for mid-September in Houston, but certainly we often see these kinds of warm stretches this month. It’s not as bad as August, but it’s still pretty hot, and sometimes excruciatingly so in September as we eagerly await the onset of fall. But for those who like summer, and I know there are some of you thermophiles out there, this is a good opportunity for water outdoor activities before things cool off. Nights will only drop into the mid-70s. Humidity will be pretty high, but not as high as it gets during the peak of summer. Rain chances will be close to zero over the weekend.

Next week

The ridge retreats a bit next week, and this may allow for some slight rain chances on Monday, maybe in the 20 percent range. Still, most of next week looks pretty sunny, and highs are going to be in the low 90s most days, with the possibility of a few mid-90s here and there. So yeah, pretty hot and mostly rain-free probably. Our next front may be in the cards about 12 days from now, but I wouldn’t bet on it.

Tropics

Francine has moved inland, and while there are a lot of tropical blobs out there, right now it looks as though none of them are coming toward the Gulf of Mexico. We just need that pattern to hold on for a few more weeks…

In brief: Francine is making its closest approach to the Houston area this morning, but remains a non-issue for the state of Texas. We’ll see one more cloudy and somewhat cooler day, with a chance of showers, before summer returns for a spell. We look to be solidly in the 90s for awhile after today.

Francine status

Francine has substantially increased in intensity overnight, reaching 90-mph winds. It should become a Category 2 hurricane before reaching the Louisiana coast this afternoon or evening. The storm will bring serious impacts to major populated areas of the state, including Baton Rouge and New Orleans. We will provide continuing coverage of these impacts on The Eyewall.

Locally in the Houston area, the impacts have been minimal. The storm’s center is now making its closest approach but is still more than 150 miles off the coast from Galveston. We have seen some slightly elevated winds—there was a single gust of 38 mph in Galveston last night—but for the most part sustained winds even along the coast have been 15 to 20 mph. For all practical purposes it has been a non-event locally.

Wednesday

We’ll see mostly cloudy skies today, and that will help to keep high temperatures in the mid-80s. We’ll continue to experience north-northeasterly winds from the hurricane’s passage, and at times these could produce gusts of 20 to 25 mph. However, there will be nothing too out of the ordinary from this. Finally, we’ll see some scattered, mostly light to moderate showers throughout the day today. But overall rain chances for any given location are probably 50 percent or less. Low temperatures tonight will drop into the low 70s.

Thursday

Due to rains in late August and early September, and then the passage of Hurricane Francine, the Houston area has experienced a stretch of mostly 80s-days in terms of temperature. But just as a reminder, we’re still in September, and summer is not in fact over. We’ll be reminded of that, beginning Thursday, as the mercury starts to climb again. Highs will reach about 90 degrees, with mostly sunny skies and plenty of humidity. Lows will drop into the mid-70s.

Friday, Saturday, and Sunday

The weekend looks hot and sunny, with high temperatures in the low- to mid-90s. This will be due to Houston falling under the influence of high pressure. A very slight chance of rain returns to the forecast by Sunday, but it’s probably only 10 or 20 percent.

Next week

Houston could see a weakness in the high pressure system by the early part of next week, which could bring perhaps a 30 percent chance of showers for a few days. But for the most part of next week I expect partly to mostly sunny skies, with highs in the low- to mid-90s. There is a chance of a front about 12 to 14 days from now, but only a chance.

Tropics

Beyond Francine the National Hurricane Center is starting to track more potential areas of development. However, at this time I don’t see any particular threats to the Gulf of Mexico. For this time of year, that’s a great place to be.

In brief: This is a short post to wrap up our coverage of Tropical Storm Francine, which as expected is having a negligible effect on Texas as it remains well offshore. We also take a look ahead at potential tropical activity over the next 10 days or so.

Francine forecast

As of late this afternoon, Tropical Storm Francine is located due east of the mouth of the Rio Grande River, about 135 miles off the coast. This is about as close as the storm is going to get to Texas as it has assumed a northeastward movement that will take it toward the Louisiana coast. Forecasters at the National Hurricane Center expect the storm to reach the south-central coast of Louisiana by Wednesday afternoon as a Category 1 hurricane.

We have been, and will continue to cover the implications of Francine for Louisiana on our sister hurricane website, The Eyewall.

Houston-area impacts

Not much. We’ve seen some sporadic showers today, and that will continue tonight and into Wednesday morning. Inland winds will not be far above normal levels, and even along the coast I don’t expect gusts to exceed 35 or 40 mph, which is not something to be overly concerned about. Tides will run 1 to 3 feet higher than normal tonight and Wednesday morning.

All of this, to the extent that there is anything, will be gone by Wednesday afternoon. The main impact from Francine for Houston is lower temperatures, with highs in the mid-80s today and Wednesday. We’ll be back in the low- to mid-90s soon, so enjoy this.

What’s next in the tropics?

In short, not much we need to worry about. The National Hurricane Center is tracking a couple of areas of low pressure in the Central Atlantic Ocean. However, none of the reliable models bring either of these systems, if they develop at all, toward the Gulf of Mexico. Beyond that, the Gulf of Mexico looks pretty quiet for the next ten days. We’re getting closer to the end of the tropics season for Texas, which is great. But we’re not there yet.

In brief: Francine remains a strong tropical storm this morning, and we’re beginning to see the turn from northwest movement, to northern movement, to northeast that will ultimately carry the storm well away from Texas. Local impacts, for many not along the immediate coast, will be difficult to discern from a regular late summer-day in Houston.

Francine status and forecast

The overall forecast for Francine remains much as we have been saying for a couple of days now. The tropical system will remain well offshore from Texas, and effects for most of our area will be minimal. In fact, I would go so far as to say that by tomorrow people in Houston will be going, “Hurricane? What hurricane. This was a joke.” Well, people who didn’t know better will be thinking that at least—but not readers of this site.

Francine will not be a joke for southern Louisiana. The tropical storm has sustained winds of 65 mph, and is likely to move inland Wednesday afternoon or evening as a Category 2 hurricane. The state’s most populated area, from Baton Rouge to New Orleans, will be directly impacted with winds, rains, and storm surge. For complete coverage of these impacts to Louisiana, be sure to check our ongoing coverage at The Eyewall later this morning.

Tuesday and Wednesday

There are showers just offshore the Texas coast this morning, and the question is how far rains from Francine will penetrate inland into the Houston metro area today and tomorrow. The answer, I think, is not all that far. Based upon high resolution modeling, I expect to see a band of showers reach the coast around noon today, and then fall apart fairly quickly as it moves inland. Then, the region will see scattered rain chances through Wednesday evening. All in all, I could see the coast picking up 1 to 2 inches of rain, with inland amounts significantly less. Areas such as Katy or Tomball may not see any rain at all.

In terms of winds, I don’t expect much. If anything, the eventual track of Francine has pushed further to the east over night, and this really keeps the stronger winds at bay. We could see gusts of 25 mph or so in the city of Houston by Tuesday night, and perhaps 30 to 40 mph along the coast. But I don’t expect conditions seriously worse than this, and these kinds of winds will be fine if you need to be out and about. Seas will rise 1 to 3 feet above normal at high tide for coastal areas, including Galveston Island and Bolivar Peninsula.

The bottom line is that, for most of the Houston area, you won’t be able to tell there’s a hurricane passing offshore today and tomorrow. Skies will be mostly cloudy, with highs in the mid-80s, which is cooler than normal for this time of year. Perhaps that’s our greatest takeaway from this storm, some slightly cooler days. I’m not complaining.

Thursday

We may see a few lingering showers on Wednesday night, but by Thursday we should see sunny skies and light, northwest winds at 5 to 10 mph. Highs will reach about 90 degrees.

Friday, Saturday, and Sunday

The weekend looks hot and partly to mostly sunny. Daytime temperatures will get into the low-90s for most locations, with nighttime temperatures in the mid-70s. If I squint I can make out a slight chance of rain returning to the forecast by Sunday, but it is probably only in the vicinity of 10 to 20 percent.

Next week

I don’t see much of a pattern change next week, as highs should remain in the low 90s, with low-end rain chances and plenty of sunshine. This is fairly typical, if slightly warmer than normal weather for mid-September, and should be good for the pool, beach, or whatever outdoor water activities you care to partake in.

Next update

We’ll have a brief update on Francine later this afternoon. Don’t expect any significant track changes that will impact Texas, however.
