Houston is about to have its final fling with excessive heat this year (I hope)

Good morning. High pressure is starting to build back over the Houston region today, and that will lead to four days when temperatures will likely reach 100 degrees, or higher, for most of the region. Friday looks especially hot, with highs near 105 degrees possible for inland areas. But by this weekend high pressure starts to weaken. Accordingly, next week, our temperatures are going down into the mid-90s, at least, and we’ll start to see some better rain chances.

Daytime highs with “moderate” heat? Is such a thing even possible in Houston? (Weather Bell)

Wednesday

Today will be sunny and hot. Before the high pressure system fully asserts control, we’re going to have a puncher’s chance of rainfall today. I’d say there will be about a 20 percent chance of a brief shower. Otherwise, high temperatures will reach about 100 degrees with mostly sunny skies. Winds will be light, coming from the southeast later today.

Thursday and Friday

Both of these days are likely to bring highs in the low 100s for much of the metro area, with sunny skies. Winds will be light, out of the west to southwest. If I squint, I can see some scenarios in which there are a few isolated showers on Thursday, but it’s not something I’m holding my breath for.

Saturday and Sunday

As mentioned above, Saturday is likely to be the final day, of four, that could see highs of 100 degrees. Conditions will be mostly sunny and hot. However, by then the high pressure system will be easing westward, opening the door to some chances for scattered showers. Sunday should be a bit cooler, with highs in the mid- to upper 90s, and more scattered showers. Call it a 30 percent chance for each day, subject to modification.

Next week

High temperatures next week should be in the range of the low- to mid-90s. We may also see cooler nights, in the 70s. There’s even the chance of a weak front and some slightly drier air. We should also see daily rain chances in the vicinity of 20 to 40 percent. So all in all, quite a bit of moderation from the summer of hell conditions we experienced for most of June, July, and August.

Tropics

As we discussed at length on Tuesday, the Gulf of Mexico remains largely closed off to tropical activity for now, and likely the next two weeks. However there is a potentially very strong hurricane developing the central Atlantic Ocean, Lee, which is likely to eventually threaten Bermuda and possibly interests along the U.S. East Coast.
