STORM CHANCES
The next several days will feature only small, afternoon chances for storms. A cap on the atmosphere (like a lid on a pot) likely keeps storms at bay. That said, should a storm break through that lid, severe weather is likely. The Storm Prediction Center does have San Antonio on the edge of a low-end risk for severe storms Friday evening. We’ll be watching.
