Eye on the Tropics: The Atlantic slumber will probably push into August

Another week with a quiet Atlantic basin. No complaints here, though we really do need some rain.

Tropical outlook in a sentence

The Atlantic basin seems likely to stay mostly dormant for at least another week, as no reliable modeling is indicating any meaningful development anywhere at this time.

What gives?

Surely by now we should have had another system, right? Not necessarily. If we look at climatology, the fourth named storm of the season usually doesn’t occur until mid-August. So, we’re tracking in line with climatology. Of course, when the sales pitch coming into this season was for it to be another busy year, an average start may raise a few eyebrows. I still wouldn’t read too much into things at this point, and I would still almost certainly expect the season to finish busier than normal. But for now, just know that this isn’t out of bounds in terms of what is typical, even in active seasons.

Where to watch

While we see absolutely nothing in the models that suggests any sort of tropical development is likely over the next 2 weeks, a look at where storms have historically originated from August 1 through 10 is telling.

Historically, storms have formed in the Gulf or just east of the Lesser Antilles in early August. (NOAA)

Two clusters stand out in the Atlantic: First, the Gulf and second just east of the Lesser Antilles. So if we wanted to look somewhere for tropical development over the next week or two, those would be good places to start. The Gulf is interesting because so many storms formed *in* the Gulf. In other words, you’re more like to get “homebrew” storms than long trackers right now. So while we believe things will be quiet over the next week or two, it’s always important for meteorologists to keep tabs on any thunderstorms that find their way into the Gulf for that reason.

The Gulf is warm — does it matter?

One question we’ve been getting more and more of lately is whether or not the hot weather this summer has led to the Gulf being abnormally warm. The answer is yes.

This anomaly map shows that the Gulf is much warmer than normal almost everywhere but especially in the central and eastern portions. (Weather Bell)

The Gulf is much warmer than usual virtually everywhere. It’s especially notable south of Louisiana, Mississippi, Alabama, and off the west coast of Florida. The thing about a warm Gulf, however, is that, while not great to see, it doesn’t overly concern us because a.) things can change quickly if the pattern were to change and b.) the Gulf is almost always going to be very supportive of tropical systems. In other words, it’s not a guarantee that we’re in for trouble this year. But it does give us some pause. Of course, tropical storms need more than just warm water. One of the best examples of a Texas storm that struggled despite a fairly warm Gulf was Tropical Storm Don in 2011. While the Gulf wasn’t quite as warm as it is this year, it was still warm. Don got absolutely annihilated by dry air due Texas’s drought, as well as wind shear. Then you get years like 2005 or 2020 where everything hits the warm Gulf and seems to explode. Again, not great but not a promise of ugly days ahead. We’ll of course keep watch!

Parts of Pearland and Friendswood were Monday’s rainfall lottery winners. Will you win today?

Sorry for the late post! Pearland and Friendswood were the big winners of Monday’s rainfall lottery. Pearland saw 1 to 3 inches east of 288, centered right over downtown. Friendswood saw a bit less, around 1 to 2 inches, mainly along and west of Dixie Farm Road.

Areas east of Highway 288 in Pearland and in the Friendswood area were the rainfall lottery winners on Monday. Congratulations! (RadarScope)

That was basically the only meaningful shower in our area yesterday. We will give it another go today.

Today

Atmospheric moisture is just a little higher today than it was yesterday. This should translate to at least a few additional showers and storms in the area. Indeed, we are already seeing at least a few showers on the radar as of this later than usual post. Much like yesterday, the heaviest action may be fairly isolated, but you could quickly go from no rain to 2 or 3 inches in the right scenario. Chances today are around 30 percent. Highs will be in the mid to upper-90s to near 100 in spots.

Wednesday through Friday

Yesterday I noted how this would probably end up being the most “normal” week we’ve had so far this summer. This is very much embodied in the forecast for Wednesday through Friday. First off, the heat will remain with us: Expect mid to upper-90s each day with 70s to near 80 each morning.

As far as rain chances go, there will be little in the way of specific predictability as to where and when rain will occur over the next few days. We know that there will be roughly a 20 to 30 percent chance each day, with storms likely starting on the edge of the sea breeze moving in from the Gulf. From there, atmospheric “bumper cars” will probably take hold, where outflow boundaries (or the rain cooled breezes that precede storms) bump into each other and form new storms on their way inland. There’s little predictability to how that all unfolds, short of us saying there’s a chance of storms each day. We may get a better sense of which days have higher rain odds than others as the week progresses.

Rainfall through Thursday morning will be very, very isolated, with many places seeing nothing, but others perhaps seeing an inch or two. (Pivotal Weather)

Inland areas won’t be shut out, but their rain chances are lower than in the city and south. We desperately need rain in some of those inland locales. Per the Houston National Weather Service office, the 0.21 inches of rain in College Station since June 1st makes for the driest June/July combo on record, back to 1882.

Weekend

More of the same, as it stands right now: Sun, clouds, mid to upper 90s or hotter and low-end rain chances each day.

Next week

We have not officially hit 100 degrees since Thursday. Could that change next week? Yes. High pressure is expected to re-intensify over Texas next week, which probably means we’ll lower the rain chances a bit and dial back up the heat a little more.

The upper level pattern next week as shown by the GFS ensemble is one that implies we will see weather that we are unfortunately familiar with this summer: Hot & mostly dry. (Weather Bell)

Monday and Tuesday probably start the same as the weekend, but things begin to cook for mid to late week.

Tropics

All is quiet. We’ll have our weekly Eye on the Tropics published later this afternoon explaining more about what’s happening.

Energy conservation, smart thermostats and a reminder from Reliant

Hi all. This is a sponsored post from Reliant, who asked that we share this timely information with readers about smart thermostats and energy conservation. Thanks, Eric.

Eric and Matt don’t believe in hype and at Reliant, neither do we. There has been a lot of misleading talk
in the media and online recently about smart thermostats and how energy companies use this
technology during moments when conservation is needed this summer. Requests for conservation are
not new. They are a valuable tool often used to balance supply and demand, especially during extreme
heat waves like the one we’ve been experiencing. That’s why Reliant wants to be a source of factual
information on this topic.

The main takeaway: Consumers are always in control of their thermostats

Here’s an explanation on the role smart thermostats play regarding energy conservation in Texas:

  • Reliant’s demand response programs reward customers for reducing their usage and conserving energy during periods of high electricity demand, which ultimately helps reduce the load on the Texas electricity grid and helps customers save money by consuming less. Electricity customers must sign up for and agree to participate in a demand response program.
  • At Reliant, our program is called Degrees of Difference and it rewards customers with a bill credit for the small changes they make to reduce their usage during designated events, which are communicated to customers in advance.
  • Here’s how it works: Customers with smart thermostats have the temperature automatically adjusted by no more than four degrees during these designated events, which last no more than four hours. However, customers always have ultimate control over the temperature in their homes and can override any adjustments.
  • A do-it-yourself version of this program is also available to Texans with manual thermostats who are interested in receiving bill credits for adjusting their usage.
  • Demand response programs are separate from the customer’s electricity plan and opting in or out is easy. Customers who no longer want to participate can unenroll online or by calling our call center without penalty, cancellation fees or having to cancel their existing electricity plan.
  • We’ve also reviewed other similar demand response programs across Texas and haven’t found ANY that don’t allow customers to adjust their temperature or penalize them for opting out.

With high temperatures continuing this week and beyond, we felt it necessary to be clear on how these
programs operate and remind Texans they are always in control of their energy usage.

Stay cool, SCW readers!

Houston may be embarking on our most normal week of summer so far

The Houston area has sort of settled into a happy (?) medium this weekend with moderate heat, a good bit of sunshine, but definitely at least a handful of showers each afternoon. Some locations in northern Harris County (Louetta, Champions, Klein) saw an inch to an inch and a half of rain on Sunday. A few other areas also saw wetting showers. Some saw nothing all weekend. As we go through this week, the expectation should be for fairly similar weather: Sun, heat, and at least a few showers each day. This may actually be our most “normal” week of summer so far.

Today

Today should bring us similar weather to the weekend, with at least a couple storms around this afternoon. Coverage today may be a bit underwhelming, so consider yourself fortunate if you see one. We will likely top out in the upper-90s, similar to perhaps a touch hotter than the weekend.

Tuesday

Tomorrow will see more of the same. Rain chances should be a little higher than they will be today, however, and they may be the peak of this week. Expect maybe a 20 to 30 percent chance that you’ll win the rainfall lottery. Temperatures should be mainly in the mid-90s, but they’ll be a bit hotter where it doesn’t rain and cooler where it does.

Tuesday’s temperatures should peak in the mid to upper-90s, but they’ll be more variable depending on exactly where it rains. (Pivotal Weather)

Wednesday & Thursday

The mid to late week period will also see elevated rain chances in that 20 to 30 percent range, but again each day will be like playing the rainfall lottery. Still, it’s something. Highs will be in the mid to upper-90s.

Friday & weekend

The weekend forecast stays at least a little interesting from a rain chance perspective. A front should stall to the north of the region, allowing places like Arkansas, Missouri, Oklahoma, and Kansas to get some meaningful rain. For us, the overall pattern should kick up atmospheric moisture a bit up to about the 90th percentile or a bit higher. In simple language? There will be a little more “juice” to work with, especially Friday and possibly Saturday. Coverage of storms should increase a bit on those days before declining some on Sunday.

Houston is going to lie on the western periphery of decent rain chances this week. Unfortunately, the majority of Texas will remain bone dry. (Pivotal Weather)

It would appear that hotter, low rain chance type weather may rebound next week. More on all that in the coming days.

Tropics

All in quiet. A tropical wave in the Atlantic looked as if it could develop later this week, but model support for that has plummeted in the last 36 hours. It’s still a bit hostile out there. More in tomorrow’s tropical update.

Just a quick note: Tomorrow’s posts will likely be delayed, but we’ll have something out to you by late morning. The tropics post will get pushed tomorrow later in the afternoon or evening. Thanks for your patience!
