San Antonio residents are waking up to wet conditions this Sunday as moderate to heavy rain spreads across the city from the south, with the possibility of lingering showers and storms continuing through Tuesday. The National Weather Service has issued a Flood Advisory for parts of south Bexar County and western Guadalupe County until 10:15 a.m. Due to rainfall totals reaching up to two inches in some areas.
The cooler weather experienced on Saturday is contributing to a less severe storm potential for Sunday, but pockets of heavy rainfall are developing. Even as some areas may experience only light showers and cloudy skies, others are seeing more substantial downpours. The ongoing rain is part of a larger weather pattern expected to bring chances for precipitation over the next several days, according to the KENS 5 Weather Team.

Looking Ahead: Warmer Temperatures and Increased Storm Potential
