The hail storm was about 20 miles north of my house, I drove up there and took some pictures I can post later if you like
Now to clear up a few myths, it only hailed about 4 inches along with around 6 inches of rain which caused a lot of runoff that gathered the 4 inches of hail and washed it down stream and into the drainage gates under the highway , blocking them and making for a lot of water over the road, the 4 foot tall hail drifts are from the banks of the creeks and one from the short plane down stream from the grates,
While it is amazing to see 4 inches of hail, 4 feet of hail didn't fall, it simply collected, it has happened here many times, just not on a major highway to often,, this is only the second time I've seen it across a highway ,the first time was by Stratford Texas back in the early 90s when a similar storm happened over an ancient plia lake that highway 54 ran thru, as well as a railroad ,, the road was closed for most of the summer while the lake was pumped out, the hail from that storm was 4 to 6 feet deep in the ditches of the highway about a 1/4 mile from the lake and didn't melt for a month That storm produced 10 inches of rain and about 8 inches of hail!
