Good morning. The radar is a bit quieter this morning, so before jumping into the forecast I wanted to note a dubious record the city set last weekend. According to World Climate Service on Twitter, Saturday was the most humid day on record at Houston’s Bush airport (which has recorded hourly data since 1969), with an average hourly dewpoint of 79.7 degrees Fahrenheit. The four days from June 20 through June 23, in fact, ranked as four of the top six spots for daily mean dewpoint in Houston. As a reminder, here’s how Matt recently characterized dewpoints, and how they feel:
- 70s means uncomfortable, or typical summer
- 60s means humid, but not terrible
- 50s means mostly comfortable
- 40s or less means very comfortable or dry
Now, on to the forecast.

Wednesday
In case you were wondering, dewpoints this morning are generally in the low 70s. We’re going to see another day with scattered, daytime showers across Houston. Accumulations should be less than Tuesday, but we can’t rule out some areas seeing a 1 inch or so of rainfall, with a higher bullseye under the slowest-moving storms. Most of the area will probably see 0.25 inch or less. Highs will get up to around 90 degrees, although local temperatures will depend upon the extent of sunshine your area receives. High pressure should begin to build in this evening, shutting down rain chances area-wide.
