Omaha-area insurance companies, repair shops stay busy after storm pounds parts of city with hail | Weather

In order for large hail to form, there must be a strong updraft to support the hailstones and allow them to ice and re-coat them.

According to reports, some hailstones on the Omaha subway reached about 4 inches in diameter.

An indication of how strong the updrafts were on these storms is the heights of their peaks, she said. These storms rose to 47,000 feet.

There was good news with this hailstorm, Kern said. The wind was negligible.

Had there been strong winds with these large hailstones, the houses would have been badly damaged, with holes in the siding and windows.

Pearson said the storm produced a smaller amount of hail – about the size of ping-pong balls – when it invaded Council Bluffs and then hissed as it moved on to Iowa.

World-Herald staff, Jay Withrow and Nancy Gaarder, contributed to this report.
