FORECAST
SEA BREEZE
As high pressure shifts west, the sea breeze may be enough to stir up some brief showers Thursday through Monday. The sea breeze is a boundary created by temperature differences between Gulf waters and land temperatures. Southeasterly winds push the boundary inland and occasionally it can kick up some weak showers.

BACK-TO-SCHOOL
Monday is the first day of school for some in San Antonio. Know that not much changes from what we are seeing now. It’ll be hot & humid, while rain chances stay very low. After-school, outdoor practices will require lots of hydration!
