The severe weather threat has now ended area-wide. Here’s a recap of the afternoon including injury and storm damage reports and radar images.
1:13pm Thursday, June 28, 2018
A little impulse of thunderstorms has developed just south of Des Moines and is headed in our direction. The storm is moving through very unstable air as it continues to trek eastward across the state — so that signals a decent chance of the storm making it to our area — in a severe form. In that case, winds of 60 to 80 miles per hour would certainly be possible with this one. I think around the 3 o’clock hour is the most likely time frame the storm would reach Southeastern Iowa in our listening area — and getting into the 4 o’clock hour east of the Mississippi River in our Illinois counties. Hail and a period of heavy rainfall would also be possible.
Our cloudiness at least is helping to keep our local (already high) instability from getting worse. This is an early heads-up if you need to get the lawn cleaned up and et cetera. The storm may go through several alternating strengthening and weakening phases before it gets closer to us. That then has a big effect on the eventual size, shape, and track of the storm by the time it gets near us. There’s time yet — but certainly be advised. Stay tuned to Mix 107.3 or 101.7 The Bull for the latest.
Update: 3:13pm Thursday, June 28, 2018
The thunderstorm area, now weakening, is moving through our Illinois counties. Some 50-mile-per-hour-or-so wind gusts, along with a period of heavy rainfall, are still possible as the line of storms comes through Illinois. Overall, we’ve actually been incredibly fortunate as to how well this event has turned out. This type of an event easily could have been much worse even.
Update: 6:41pm Weather Round-up
2:00pm Memphis, Scotland County, Missouri: woman hospitalized from falling tree
2:33pm Denmark, Lee County, Iowa: power lines down

Overall, winds seemed to be fairly consistently in the 55-65 mile-per-hour-range as the line of thunderstorms came through these areas where damage and power outages are being reported. A bout of torrential rainfall came with the wind. Hail occurrence was very minimal, and the hail itself was very small where it did fall — Washington, Iowa had the largest hail report at dime-sized.
