FORECAST
WEDNESDAY AM STORMS
Another shot at rain will arrive around sunrise Wednesday. Storms are forecast to gather to our north and then dive south, reaching San Antonio by sunrise Wednesday. However, it’s likely that these storms will weaken as they approach. This means rainfall totals will likely be on the low side. Heat and humidity return by Wednesday afternoon.
Rain could disrupt parts of the Wednesday morning commute. (Copyright 2024 by KSAT - All rights reserved.)
MORE HOURS OF DAYLIGHT
We are fast approaching our longest day of year. June 20th is the summer solstice and provides us with slightly more than 14 hours of daylight. Thereafter, days will start to get shorter.
