STORMS LIKELY TUESDAY NIGHT (10PM Tuesday night to 5AM Wednesday)
If you’re going to a Spurs watch party tomorrow night, please pay close attention to the weather, as storm chances will pick up after the game. An upper-level energy will help to touch off storms to our west. These storms will move east overnight, bringing good chances for rain. These storms may be strong, while also producing heavy rainfall. The main risk is for street flooding, with a secondary threat for up to 60 mph wind gusts.

After Tuesday night’s round of storms, odds for rain decrease. A few more pop-up storms may return Wednesday and Thursday afternoons. Friday looks to be rain-free. A front late in the weekend may help to stir up more storms for the Sunday to Monday timeframe.
