FORECAST
TONIGHT
We are still watching a line of showers and thunderstorms move in from the west. Most of these will be non severe and will provide a heavy downpour and pea sized hail. Overnight these will continue to gradually weaken, clearing out for most by morning.
SUNDAY
Most of the rain Sunday will stay well south of San Antonio. There will be some peeks of sun, and temps will stay cool -- in the 60s. Clouds will thicken Sunday night, with a few sprinkles possible.

MONDAY
An upper-level disturbance will bring another round of showers. While the rain won’t be heavy, off and on showers are possible throughout the day. This will keep temperatures cool, with highs struggling to get out of the 50s. Showers may try to wind down a bit in time for the Texas Cavaliers River Parade, but plan for cool & damp conditions.
