Saturday downpours trigger flash flooding, large hail across South

According to the National Weather Service Office in Greenville, South Carolina, widespread damage was reported in Rock Hill, a community outside of Charlotte.

DALLAS – A stalled frontal boundary from Texas and across the Southeast triggered thunderstorms on Saturday that dropped heavy rainfall and large hail.

The Carolinas were the recipients of damaging hail that was estimated to be at least the size of softballs.

According to the National Weather Service Office in Greenville, South Carolina, widespread damage was reported in Rock Hill, a community outside of Charlotte.

Photos and videos showed large hail stones damaging cars, trees and awnings.

PowerOutage.us reported more than 25,000 electrical outages across South Carolina with most situated in York County.

Further west, NOAA's Weather Prediction Center had much of East Texas in a Level 2 out of 4 flash flooding threat into early Sunday morning.

Thunderstorms moved down I-20 on Saturday morning on the outskirts of the Dallas Metro area. Although not severe, these storms generated 300-500 lightning strikes every 5 minutes, the FOX Forecast Center said. 

There will be widespread areas of 1-2 inches of rain, with some spots reaching 3 inches of rain through Sunday morning. The heaviest accumulations appear centered over East Texas, but communities as far east as Alabama could see at least an inch of rainfall.

Storms will track into the Southeast by Sunday as an area of heavy rain will follow suit, with cities like Atlanta, Birmingham, Alabama and New Orleans seeing their rain and storm chances dramatically increase Sunday. At the same time, those across Texas begin to dry out.

Though rain amounts won't be as high as across Texas, moisture levels will remain above average, and instability will be present, supporting higher rain rates and an instance or two of minor flash flooding.
