SAN ANTONIO – Keep those umbrellas handy.

Rain will continue into the weekend with possible strong storms by Saturday.

Moisture continues to increase across South Texas on Thursday, keeping cloudy skies and areas of drizzle and light rain.  

Most places will only see a trace of rain, with maybe the occasional 10th to a quarter of an inch in isolated areas.

By Friday, the atmosphere will be saturated.  That means you'll still see cloudy skies and you'll feel the high humidity in the air.  

Scattered showers will persist through the day Friday. As temperatures warm into the 70s, a few isolated thunderstorms could pop up by afternoon.  

A few isolated strong storms could develop in the Hill Country on Friday afternoon and evening, but the risk is very slight. Best chances for severe weather on Friday will stay north and west of San Antonio. 

But that won't be the case on Saturday, when a strong upper-level low pressure will move south into the region. With dewpoints in the mid 60s by this time, thunderstorms will be likely along and ahead of the advancing cold front.  

Heavy thunderstorms - possibly some severe storms - will develop and move through South Texas beginning late morning and continuing through the afternoon.  

The area of concern will begin along the I-10 corridor and then shift south and east through the late afternoon.  

The main threats will be large hail and damaging winds.  However, conditions are favorable for discrete supercell thunderstorms, which means isolated tornadoes cannot be ruled out.

The entire storm system will move out of the area by Sunday, leaving us with sunny skies and mild temperatures through the holiday next week.
