HOUSTON, Texas (KTRK) — Sunday will be a repeat of Saturday. Temperatures are starting in the mid-upper 70s and will quickly climb into the upper 90s under a mostly sunny sky.
By lunchtime temperatures could be above 90 degrees with a heat index making it feel like close to 100 degrees already. The combination of heat and humidity will push the heat index around 105 Sunday, just shy of Heat Advisory territory.
Ozone levels could again reach unhealthy levels during the peak heat of the day. This invisible gas is a lung irritant that can trigger asthma attacks in sensitive individuals. The pollution levels should peak between 3 p.m. and 7 p.m., so it is best to get in any outdoor activities in the morning.
How many days will ozone pollution be a concern?
With rain chances returning Monday along with a southerly wind, we think Sunday will be the last day (for now) with an Air Quality Alert.
When will higher rain chances return?
The next best chance of rain arrives Monday and Tuesday, but even then it’s only 30%. We’ll get grazed by some tropical moisture, and that should be even to get a few afternoon thundershowers developing along the sea breeze front both days. After Tuesday, the heat ridge will again settle back over Texas to push highs toward 100 again next weekend.
What are you tracking in the tropics?
A tropical wave in the central Atlantic now has a 90% chance of development over the next seven days. This wave will likely become Ernesto over the next week. Head to our daily Tropical Update page for the latest on what’s happening in the tropics.
