Ozone pollution and heat dominate the forecast until the weekend
HOUSTON, Texas (KTRK) -- We are in the middle of our hottest stretch of weather so far this summer, and it's also having a negative impact on our air quality.
Ozone levels are once again expected to reach unhealthy levels on Wednesday just like we observed on Tuesday. This invisible gas is a lung irritant that can trigger asthma attacks in sensitive individuals. The pollution levels will peak between about 2 p.m. and 7 p.m.
Wednesday will start off warm with lows in the upper 70s, then temperatures should rise into the low 90s by noon and the upper 90s between 3 p.m. and 5 p.m. While we can't rule out a stray sea breeze shower, it will likely stay dry for all.
How many days will ozone pollution be a concern?
At this time we think the ozone levels could reach concerning levels each afternoon through Saturday. We'll monitor the pollution sensors for you and let you know where any issues pop up.
Just how hot will it get this week?
We expect the temperature in Houston to top 100 degrees Thursday through Saturday with the hottest day being Friday. That's when we predict a high of 101.
When will rain chances return?
This weekend! A weak summer front will slide into Southeast Texas early in the weekend, which could help usher in a few showers and storms Saturday and Sunday. The highest chance for rain looks to be Sunday, and even then it's only 30%. Otherwise it will simply be hot this weekend with highs in the upper 90s to low 100s.
What are you tracking in the tropics?
Tropical Storm Debby will move at a slow pace up the east coast bringing heavy rain and flooding to that part of the US. There is another tropical wave we're keeping a close eye on that's currently in the central Caribbean. This wave has a 30% chance of development over next 7 days and could eventually get into the Gulf of Mexico this weekend.
