Month: September 2017

Back to regularly scheduled late summer

Admittedly, it was probably too good to be true to think we could get through September with completely pleasant weather. The weather pattern over most of the United States is actually going to make a pretty significant shift from where it’s been since early August. This means typical late summer weather for Texas. On to the details.

Today & Friday

While both today and tomorrow will be on the hotter side, it will actually be rather nice still. Yes, there will still be some haze around unfortunately. But it will be mainly sunny, with fewer clouds today, and we’ll keep that up into Friday. High temps will peak in the lower 90s, with morning lows in the lower or middle 70s. Rain chances are near zero both days.

Weekend

Expect similar temperatures this weekend, with highs in the lower 90s and nighttime lows more in the mid-70s perhaps. The warmer nights are courtesy of increased humidity, which will also signal our first chance of showers this month. Yesterday was our 14th straight day without rain. Given Harvey, you couldn’t script that any better, but of course it will still eventually rain again in Houston.

Rain totals this weekend should be extremely modest, a tenth to a quarter inch on average. Many of us won’t see any rain at all. The better chance of the two days will be Sunday.

Summer lite returns to Houston, and it will remain awhile

Nine years ago today, Hurricane Ike made landfall along the northern end of Galveston Island. Of a hurricane’s three major threats—damaging winds, storm surge, and inland flooding—Ike’s greatest damage came from its surge along the coast. In the nearly decade since then, we’ve done nothing to mitigate the problem of surge. It would be a great shame if we make the same mistake with regard to inland flooding after Hurricane Harvey.

Now, onto the forecast.

Wednesday through Friday

Southerly winds are back, and with it comes increased humidity and warmer nights. Overnight lows this morning are nearly 10 degrees warmer than just 24 hours ago. We won’t see too much of a difference in high temperatures over the next several days, with the mercury climbing to about 90 degrees or so. But it will feel warmer, given the increased moisture and humidity. This is more typical weather for September.

End of Texas tropics season may be near as Houston warms back up

Well, it has been a busy few weeks in the tropics with hurricanes Harvey, Irma, Katia, and now Jose meandering around the Atlantic Ocean. (Speaking of Jose and its track forecast, while the 75-mph storm may move back toward the US East Coast this weekend or early next week, as of right now it most likely will stay offshore). Perhaps not surprisingly, the Atlantic season reached its “peak” of activity on Sunday. As you can see, however, a good bit of activity historically continues into early November.

But for Texas it’s a different story. I am not ready to declare an end to the Texas hurricane season, but long-time readers will recall that after Sept. 24th the chance of a hurricane hitting the state are historically quite low. Moreover, forecast models show little to no tropical activity in the Gulf of Mexico for at least the next week or 10 days. So we’re getting close to that date, and after Hurricane Harvey we’ve certainly had enough of the tropics for awhile. I’ll post later this month when I think we’re all clear on the tropics front.

Now let’s take a look at our forecast for the next week.

Do you miss the rain yet, Houston?

For Houston, Hurricane Harvey’s rainfall ended on Tuesday, August, 29. A few parts of the region have seen some light showers since then, but essentially it has been bone dry for the last 12 days. This has been exactly what the doctor ordered in terms of recovery from what likely will be the costliest natural disaster in US history. And the low humidity has been nice too. Yet already, our soils are starting to dry out. So when is the rain going to return? The short answer is not soon.

Today

For most area school districts, this morning represents a second “back to school” day, and we will have fine weather, with lows this morning in the 60s, and highs today in the mid- to upper-80s.

Tuesday

We’re going to have one more really nice fall-like day on Tuesday, with lows generally in the low 60s across the area and some really nice, dry air blowing in from the northwest. Highs will be in the upper 80s. Savor the mornings, because change is coming.
