KEY POINTS:
-
Hot weekend with peak heat index values as high as 107°
-
Small chance for thunderstorms both Saturday and Sunday evenings
FORECAST DETAILS:
The last 100-degree day in San Antonio was way back on July 6, 28 days ago. We’re likely to hit 100° this afternoon with a peak heat index of 105° to 107° thanks to high humidity. There’s a small chance (20%) for a stray thundershower after 5 p.m. Saturday.
Sunday starts with mostly cloudy skies and even a sprinkle or two. But with quickly clearing skies, we’ll warm up to near 100° in the afternoon. Slightly better, but still low, rain chances (30%) Sunday after 4 p.m.. Chances for rain are not high enough to cancel Sunday evening plans. However, if you happen to get a storm, you could experience gusty winds and heavy rain. Plan to have the radar handy Sunday evening, just in case!
Otherwise, the week ahead will be typical for August: hot and humid with little-to-no chance for rain. Have a nice weekend! ~ Sarah
