A number of thunderstorms this afternoon produced severe hail of 1.00” diameter or greater in northwest Iowa. The storms were elevated and posed no risk of producing tornadoes. But there’s just enough energy in the atmosphere to boost hail. So far it appears as a storm begins to weaken, the hail core collapses and drops up to 1.75” (golf ball) diameter hail over an area.
The good news is these storms are cyclical, and are not tracking over a large area. Hail reports are coming every so often when a storm can gather enough strength. Isolated strong storms remain possible over the next few hours. But again, no organized severe weather outbreaks are expected today.
