 Air quality concerns persist as temperatures climb across Montgomery County

Residents across Conroe, the Woodlands, and Montgomery County should prepare for another stretch of hot, mostly sunny weather through the weekend, with afternoon temperatures in the mid-90s and heat index values expected to exceed 100 degrees.

Forecasters say a persistent high-pressure system will keep rain chances limited through Sunday while maintaining above-average temperatures across Southeast Texas.

Daytime highs are expected to range from 94 to 95 degrees each afternoon, while overnight lows will remain warm in the mid-to-upper 70s. Although rain chances will hover between 10% and 25%, humidity will make conditions feel significantly hotter during the afternoon.

Thursday will be sunny to partly cloudy with a high near 94 degrees and light southerly winds. Similar conditions are expected on Friday, with a high around 94 degrees and a heat index approaching 105 degrees.

Saturday will bring mostly sunny skies with highs in the mid-90s and overnight temperatures around 77 degrees. On Sunday, partly sunny skies are expected with another afternoon high near 94 degrees before temperatures fall to around 78 degrees overnight.

Air quality across the region is forecast to remain in the moderate-to-poor range, meaning conditions are generally acceptable for most people but may pose health risks for individuals who are especially sensitive to air pollution.

The primary pollutants expected are fine particulate matter (PM2.5) and ground-level ozone, both of which tend to increase during prolonged periods of hot, sunny weather with limited rainfall.

Health officials recommend that children, older adults, and people with asthma, heart disease, or other respiratory conditions reduce prolonged or strenuous outdoor activity during the hottest part of the afternoon when ozone levels are typically highest.

Residents are also encouraged to stay hydrated, wear lightweight clothing, limit outdoor work during peak heat, and check on elderly family members and neighbors during the extended period of high temperatures.

With little relief expected through the weekend, forecasters advise residents to continue monitoring local weather and air quality updates before spending extended time outdoors.
