Heat building, rains ending, as summer solstice looms

As the reality of summer settles in for Houston, we can offer you one saving grace—the summer solstice is just six days away. June 20th will be the longest day of the year at 14 hours, 3 minutes. The Sun will be almost directly overhead during the middle of the day, at 84 degrees altitude. After passing the solstice, we’ll at least be able to begin counting down toward fall as days get a little bit shorter beginning next week. It’s a small hope, but the only hope we can offer at this point.


High pressure will begin to build over the area today, but there’s enough moisture to still squeeze out a few showers for Houston, especially over the eastern half of the area. They will be scattered and likely brief. Highs otherwise in the low 90s.

Thursday through Sunday

June-like weather will prevail as high pressure builds over the region. That is to say, we’ll see high temperatures generally in the low 90s, lows in the upper 70s, with partly to mostly sunny skies and almost nil rain chances. 

Next week

The models have gone back and forth on the extent to which the high pressure breaks down, and flopped around on rain amounts, for most of next week. Right now I’m pretty confident that the first part of next week will be hot (mid- or upper-90s, anyone?) and mostly dry, but there are still some questions about rain chances during the second half of next week. From Wednesday on we could see a little rain in the form of scattered showers, or (less likely) as much as a few inches (see below).

The tropics

I mentioned the tropics heating up on Monday, and the National Hurricane Center is tracking the potential development of two systems.

We are keeping an eye on the system near the Yucatan Peninsula, and the European model has been toying with its strengthening in the Bay of Campeche. For now I don’t think it will have any significant effects on the upper Texas coast. But if it does, it could increase our rain chances during the second half of next week. This isn’t anything to overly concern yourself about, but it is a good reminder that hurricane season has begun, and something we’ll need to be cognizant of over the next 3.5 months.
