If you’ve been missing summer, you’re in luck. It returns for a one-day engagement Thursday with highs of around 90 degrees. My guess is that we’ve only got two or three days with 90-degree temperatures left in 2019, so if you really like the heat please get outside and enjoy it today. Cooler weather arrives Friday.
Today will be quite warm, with highs of 90 degrees in the city of Houston, and possibly mid-90s just to the west, in places like Katy. Mostly sunny skies will amplify the heat, and we’ll get no respite from the humidity as the sun goes down tonight. (Just as the Tampa Bay Rays will not get any respite from the Astros’ bats tonight).
But that all changes on Friday. A potent fall cold front has been sweeping down the central United States, and it will reach the Houston area on Friday morning. Areas such as College Station will likely see the frontal passage before sunrise, and it should move into central Houston by around 10am, and push off the coast around Noon. A broken line of light-to-moderate showers should accompany the frontal passage, but any storms should be short-lived.
Conditions after the front will be significantly drier, cooler, and gustier. We can’t entirely rule out some light rain after the front’s passage, but for the most part it will be just cloudy. With the lack of sunshine, and winds gusting to 25 mph (or higher, along the coast), you may well want a longer-sleeved shirt or light jacket on Friday afternoon and evening.
Lows on Saturday morning will be the coolest they have been since at least mid April, and possibly early April depending on how cool things get across the city. But generally, most everyone but the immediate coast will see lows in the 50s.
Overall, this will be a fairly cool day, with a persistent northerly breeze at 10 to 15 mph, partly sunny skies, and high temperatures in the low- to mid-70s. It will be excellent for doing any kind of yard work outside, cleaning out the garage, or what have you.
Lows Sunday morning will be a few degrees warmer than Saturday morning, but much of the region should still dip into at least the upper 50s. Sunday will be a fine, mostly sunny day with high temperatures of around 80 degrees.
As we’ve discussed, next week will see the return of warmer weather, with perhaps 20 to 40 percent rain chances each day beginning Monday. A weak front may push into Houston by later Wednesday or Thursday, but at this point it doesn’t appear likely to pack too much oomph.
