Don’t look now, Houston, but August is almost over. Fall comes not today, but it likely is just weeks away

Today is August 29. There are just three days left in the month that I consider to be the worst of the year in Houston, weatherwise. August is consistently the hottest, most humid, and often the month with the worst drought conditions of the year in our region. That has unquestionably been the case this month, with record heat and, for most of the area, very little rainfall. And now it’s almost over. Good riddance.

Matt and I have a friendly debate about whether August or September is the worst month in Houston. His point is that, in the rest of the country, fall starts settling in in September, whereas in Houston we often see some of the warmest weeks of the year in September. While I understand Matt’s point, he is entirely wrong. At least in September we have the hope of seeing a bonafide cold front. Typically we see our first real front during the third or fourth week of the month. Hope may be a dangerous thing, but at least I have it in September.

A cold front, by the way, is moving through the region today. Since it is August, however, this is an August front. Which is to say we’re going to see some drier air and (very) slightly cooler weather. This is not unwelcome, but it is not a front that will make you say, “ahhhh” either. Looking into the medium-term, there is no sign of a stronger front in the next 10 to 14 days, but rest assured it is coming. Probably within the next few weeks. We’re getting there, friends.

Tuesday

Thanks to the aforementioned front, high temperatures today will only top out in the mid- to upper-90s. With dew points dropping into the 60s, or even 50s further inland, this air will feel somewhat comfortable this afternoon for all areas but the immediate coast. Skies, otherwise, will be mostly sunny, with a northerly wind at 10 to 15 mph. Rain chances are effectively zero percent. Lows tonight will drop into the mid- to upper-70s for much of the area. The bottom line is that this evening should feel a bit more pleasant outside, especially as the Sun goes down.

Wednesday

Dew points will bottom out on Wednesday. So although highs will push the upper 90s to 100 degrees, the air will again feel fairly comfortable during the daytime. Lows will drop into the 70s on Wednesday night, and a few areas far from the coast may even briefly touch the upper 60s. Enjoy this as a promise of what’s to come. The only downside is that we really, really need some rain, and none of that is in the cards before the weekend with the drier air.

Thursday and Friday

These will be days a lot like Wednesday, but we’re going to see dewpoints start to creep back up, so you’ll feel the humidity a little bit more each day. By Friday evening, I’m afraid, the front should be long gone.

Saturday and Sunday

Highs this weekend should be in the mid- to upper-90s with mostly sunny skies. Some inland areas will probably push 100 degrees. As moisture levels rise, we could see some rain showers kick up along the sea breeze during the afternoon or early evening hours, especially on Sunday. Rain chances are probably on the order of 20 to 40 percent each day, at least at this stage. Expect some refinement as we get closer to the weekend.

Next week

This pattern looks to more or less hold next week, with highs in the upper 90s for the most part, with low- to decent rain chances. See, September is already better than the 109-degree temperatures we were experiencing in August.

Tropics

There’s likely to be a major hurricane in the Gulf of Mexico later today, Idalia. This storm presents a significant threat to the Gulf coast of Florida, particularly the Big Bend area of the state. We have full coverage of this storm, and the rest of the Atlantic tropics, on The Eyewall.
