More rain Saturday; flash flood watch extended through 7 a.m. Sunday

SAN ANTONIO – Here we go again.  

Expect rain throughout the day Saturday, but it'll be intermittent in nature with breaks between the downpours.  

Upper energy, a weak surface low and abundant moisture are combining to produce the batches of downpours cycling through South Texas.  

Flash flooding is the primary threat as the ground is already saturated, so it won't take a whole lot of rain to cause areas of rising water on some roadways.  

Lightning should be limited with hail and severe storms highly unlikely.  

Most of South Texas can expect 1 to 3 inches of rain but pockets of 3 to 8 inches of rain 1"-3," but pockets of 3"-8" are possible by Sunday morning.  Otherwise, a few peeks of sunshine are possible in between the downpours, causing temperatures to briefly make it into the lower 80s.  

This is a progressive system, so the rain should gradually push west of San Antonio into Sunday morning with most of the rain on Sunday falling closer to the border.  

A few passing showers and partial sunshine are in the works for Sunday with highs in the upper 80s and very humid air in place.  

Overall, the week ahead is looking predominantly dry with sunshine, but we're keeping an eye on the potential for more rain by next Friday and Saturday.  

We'll keep an eye on it, so check back for updates.
