Austin is waking to mostly cloudy skies and temperatures around 78 degrees Tuesday morning, but the brief cloud cover will not do much to soften the day ahead. Forecast highs are expected to reach 101 degrees, with heat index values climbing as high as 108.

Triple-Digit Heat Arrives Tuesday

Skies should turn mostly sunny as the morning progresses, while south winds of 5 to 10 mph bring occasional gusts up to 20 mph. Rain is unlikely in Austin, with a 1% chance of precipitation in the local forecast.

The National Weather Service says no watches, warnings or advisories are currently in effect for the area, but forecasters continue to urge residents to practice heat safety as the hot, mostly dry pattern holds.

Evenings Stay Warm Through Wednesday

Tuesday night will be partly cloudy with a low around 78 degrees, but the heat index could remain as high as 106. Wednesday looks even hotter, with mostly sunny skies, a high near 102 and heat index values reaching up to 110.

South winds Wednesday will run 5 to 10 mph, with gusts up to 25 mph. Wednesday night should remain mostly clear and warm, with another low near 78 degrees.

Little Relief Into The Weekend

Thursday is expected to bring another sunny 102-degree afternoon, followed by a mostly sunny Friday near 100. Saturday through Monday will stay mostly sunny to sunny, with highs near 101 each day and overnight lows generally between 77 and 78 degrees.

Rain chances remain close to zero through most of the extended forecast, so storms are not expected to provide much relief. Plan outdoor work and exercise for the cooler morning hours when possible, drink water regularly, and use air conditioning or shaded breaks during the hottest part of the day.
