MORE RAIN CHANCES?
Surge of moisture will arrive on the weekend (Copyright 2026 by KSAT - All rights reserved.)
A surge of moisture arriving from the Gulf on Friday should at the very least give us more cloud cover. But, downpours, some heavy, should also arrive with this airmass. As of now, our best chance for downpours will be on Saturday (30%).
