San Antonio woke under cloudy skies Tuesday with temperatures near 79 degrees, but the brief gray start will give way to another hot, humid afternoon. The high is expected to reach 94 degrees, with heat index values as high as 101 and breezy south-southeast winds adding to the discomfort.
Heat Peaks Tuesday And Wednesday
According to the National Weather Service, partly sunny skies should develop Tuesday as winds run 10 to 15 mph, with gusts of 20 to 25 knots, with the upper end equivalent to about 29 mph. Tonight will stay unusually warm, with a low around 78 and heat index values near 100.
Wednesday brings another 92-degree afternoon, with the heat index potentially reaching 102. There is a 20% chance of showers after 1 p.m., followed by a slight chance of thunderstorms later in the day.
Cooler Air Arrives Friday
Thursday stays mostly sunny and warm, with a high near 90, before a cold front moves through late Thursday night into Friday. Highs should be in the 70s for most of the area behind the front, with north-northeast winds near 20 mph and gusts reaching 35 mph.
The weekend looks considerably more comfortable, with highs in the upper 70s to low 80s and lows that could be in the 50s. Friday night could be especially blustery, with gusts up to 40 mph, so outdoor plans and lightweight decorations may need extra attention.
Heat Safety Still Matters
No watches, warnings, or advisories are in effect, but Tuesday and Wednesday will still be difficult for people working or exercising outdoors.
