Austin is starting Labor Day with clear skies and temperatures in the upper 70s, but the holiday is headed toward a near-100-degree afternoon. A brief shower or thunderstorm remains possible, though most outdoor plans should stay dry.
The forecast calls for a high near 99 degrees, with the heat index reaching as high as 104. Winds will stay light from the south, generally around 0 to 5 mph, making the afternoon feel especially stagnant.
Small Rain Chance Arrives Before Afternoon Heat
A slight chance of rain showers is expected late Monday morning, beginning around 10 a.m. That chance continues into the afternoon as isolated showers or thunderstorms develop, but the overall probability remains about 20% and widespread rain is not expected.
Any shower activity should wind down before Monday night, which will turn mostly clear with a low near 79 degrees. No weather watches, warnings or advisories are posted for the Austin area.
Triple-Digit Heat Takes Over The Week
The hotter pattern becomes more persistent Tuesday, when Austin is forecast to reach 100 degrees under sunny skies. Wednesday and Thursday should also top out near 100, followed by highs around 101 Friday and Sunday.
Saturday currently looks like the hottest day of the forecast period, with a high near 102 degrees. Overnight lows will offer limited relief, remaining in the upper 70s through the weekend while rain chances fall to the single digits after Monday.
Plan For Heat During The Afternoon
People spending time outside should take frequent breaks, drink plenty of water and limit strenuous activity during the hottest part of the day. Check on older neighbors and anyone without reliable air conditioning, and never leave children or pets in a parked vehicle.
