Residents gearing up for a blazing week in Austin might need to find refuge in the shade or crank up the AC as forecasts predict a relentless wave of heat. According to the National Weather Service, starting today with mostly cloudy skies, the city is on a trajectory to see temperatures soaring near 97 degrees, with heat index values climbing as high as 109. The warmth isn't planning on giving any respite tonight with increasing clouds and lows hovering around 78 degrees.
The heatwave continues through the week, with Wednesday and Thursday mirroring the sweltering conditions of Tuesday. Both days are largely predicted to present mostly clear to sunny skies, with highs threatening to reach the upper limits of our thermometers at 98 and 99 degrees, respectively. A calm wind will give little to no relief from the searing temperatures—asserting its presence later in the day with a feeble gesture from the south at about 5 mph. Packing an additional punch, humidity insists on maintaining its grip throughout the week, which means the "feel-like" temperatures will push into an even more oppressive range between 100-110 degrees during the afternoons.
With a mighty high-pressure system staked out over the region, as described by KXAN, Austin may just encounter less than 10% of rain coverage. Hoping for a spot shower entering the eastern counties might feel like wishing on a far-off star. However, high pressure won't stay rooted in place, as it's expected to wobble west and then back east through the week, which, unfortunately, won't likely bring noticeable relief for those on the ground.
Friday through the weekend, Austin residents can anticipate more of the same: mostly sunny, with highs persistently teetering on the cusp of triple digits. Winds from the south, picking up momentarily with gusts that might reach 20 mph, offer only the slightest reprieve. As we look out beyond the stagnant mass of heat, meteorologists keep their eyes on a new area of potential tropical development. It's projected to make its entrance into the Gulf of Mexico, currently having a mere 20% chance of maturing into a tropical depression. Nevertheless, any development there could stir the stillness that's gripped the city—a narrative all too common in these times of climatic extremities.
