FORECAST
Sure... it was a “dry” heat yesterday, but we still managed to reach 100°. That’s our third triple digit day of 2025. We do enter into a more active pattern by the weekend, so you’ll want to pay close attention to the forecast.
HUMIDITY SPIKES THIS EVENING
Muggy Gulf air will surge back into place quickly after sunset, and then it’s here to stay.
RETURN OF HUMIDITY, SMALL STORM CHANCES
As Gulf moisture surges back into San Antonio, a few storms will be possible by tomorrow afternoon. Coverage will be limited (20%). Otherwise, it’ll be a cloudy start, with a sunny afternoon. Temperatures, once again, return to the upper-90s.
MEMORIAL DAY WEEKEND
Friday through the first half of Sunday looks to be quiet, but hot. By late Sunday, an approaching storm system combined with a front may help to develop storms. At this point, the best odds for rain will be on Memorial Day and into the night. Scattered showers and storms, some strong, are possible. The timing of the front will be important and is subject to change. We’ll keep you updated!
