FORECAST

There are a few storms in the Hill Country that could produce some street flooding in isolated spots. This activity will be around until sunset, with a small chance (20%) of it reaching San Antonio metro area.
THIS WEEK
Daytime temperatures will slowly climb, peaking Wednesday and Thursday, with highs in the upper-90s.
MORE RAIN CHANCES?
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%).
