Dry air poured back into Southeast Texas yesterday, and despite high temperatures near 90 degrees, it really didn’t feel bad at all. In fact, dewpoints dropped into the 50s officially at IAH Airport for the first time in June since 2017. We’ve got one more day of this nice stuff today before we return to more standard summer.
Sunshine dominates once again. With dry air in control, we should again see humidity drop to near “comfortable” levels for many parts of the area. Look for high temperatures to pop back to 90 or better for most, however.
Winds will again be on the light side, so expect air quality to be fairly stagnant once again. While not as bad as Wednesday, today will again be an ozone action day, with poor air quality this afternoon. If you’re in a sensitive group or struggle on bad air quality days, take it easy and try to stay indoors later today. If you’re ever curious about the air quality outlook, the Texas Commission on Environmental Quality publishes 4-day forecasts each day. You can bookmark that link here.
Look for another sunny day tomorrow. The difference will be in the humidity. Dewpoints are expected to slowly rise late tonight and most of the day Friday, and they should end up back around 70, or uncomfortable, by Friday evening. Expect us to start the day pleasant (mid-60s) and finish hot (low-90s). Air quality will improve a bit as onshore winds kick up during the day.
We are still on track to return to summer this weekend. Look for high humidity, daily shower chances, and breezy weather. Expect morning lows to be in the mid- to upper-70s or low-80s and daytime highs in the low-90s. It will be breezy with 10 to 20mph winds and higher gusts over the open water. Use caution if you’ll be out boating in the Gulf or on the bays this weekend.
The combination of heat and humidity will also raise heat index values, so take it easy in the late afternoons and drink plenty of water.
In terms of rain chances, both Saturday and Sunday will have at least a scattering of showers in the afternoons, mainly as the sea breeze works inland from the Gulf. There will be an added disturbance very late Sunday or Sunday night to our north that could enhance some showers or storms up that way. But that will likely not interfere with any daytime plans.
Additional disturbances and daily shower or storm chances along the sea breeze will keep afternoons and evenings unsettled next week. Most of the day prior to that will see sun and clouds. Expect upper-70s to low-80s at night and low-90s during the day. A day or two could push mid-90s as well, along with plenty of humidity. The forecast is reminiscent of what is typical for summer around here.
