FORECAST
TUESDAY
Tomorrow will be pretty much a repeat of today’s weather, with one exception: Saharan dust will thin out, so skies will not be as hazy. Expect brief morning clouds, with abundant afternoon sun. Highs will be in the low- to mid-90s, with a heat index of close to 100°. But here’s the thing: that’s average for this time of year, not exceptionally hot.
COASTAL SHOWERS
As the week progresses, the weather around San Antonio will stay the same. However, if you live closer to the coast, you may see a brief, daytime shower from the seabreeze. Chances these make it to the metro area stand at only 10%.
JULY 4TH
