There are at least some interesting “wrinkles” in the forecast which, while not having a major shift in any of the daily predictions, do change the wording. I know what you are thinking: that I am just looking for ways to say “hazy, hot, and humid” without looking totally redundant. possibly, but for the first time in a long time there is a meager chance for rain on one day. And we may be ending our 100 deg F or higher streak this weekend.
Highest temperatures in recent days have routinely been around 101 or 102 degrees F. We should be in that realm on Thursday, with the usual display of brilliant sunshine and dry air in the mid-levels allowing for a steady rise in temperature into late afternoon. But the century mark is not a given between August 12 and 16. More moisture will work into the lower and middle layers of the atmosphere, a cold front will stall nearby (Arklatex vicinity), and random thunderstorms may pop up very close to Houston. The best chance of any convection will be in N TX on any given day or night (especially the TX Panhandle), and there is even the possibility that the scorched Dallas-Fort Worth metroplex may have one whole day without reaching 100 degrees F for a high (I am guessing Sunday or Monday). Computer forecasts say that if the Bayou City gets some rain (and not much moisture at that), most likely the precipitation will visit on Sunday night. Odds are about 1 in 10, so do NOT get your hopes up to see your lawn watered.
With a large storm progressing across southern Canada next week, the core of the heat ridge will rebuild and expand into MO and IL after August 17. Most likely, southeastern Texas will settle into that familiar (for this summer) rut of highs in the upper 90s and low near 80, with perhaps some breeze kicking up in the afternoon. The tropics will be come more active to the right of the ridge complex, implying a threat to Florida and the Eastern Seaboard between August 21 and 25. But as of now, a side storm track trip into Galveston Bay and vicinity seems highly unlikely.
