Sunday wake-up call: showers, storms, and tree damage in spots

By  | 

A line of thunderstorms moved east across the area during the early morning hours of Sunday, August 18. Some of the stronger thunderstorms caused some tree damage in parts of the Stateline.

The Storm Prediction Center had a majority of the Stateline under "Slight Risk" for severe weather through 7 a.m. The region first saw some lighter showers around 2-3 a.m. before the main line of showers and storms arrived around 6 a.m. Shortly after, the National Weather Service issued a Severe Thunderstorm Watch for the entire region until 1 p.m., though it was canceled much earlier.

Because this system was weakening as it moved across the Stateline, more impressive rain totals were the western portion of our viewing area and even further west into Iowa. Areas in Jo Daviess and Stephenson Counties had rainfall reports around an inch or locally higher.

The 23 Storm Team received some stunning pictures of the storm as it moved across the region this morning, note the shelf cloud imagery from Winnebago, Illinois and Machnesey, Park Illinois. In addition, some isolated wind gusts of 50 miles per hour or greater were reported in Ogle County, Illinois near the city of Oregon.

No reports of severe damage were reported with these storms but it was for sure a wake-up a call for many Stateline residents this morning. The next decent rainfall in the forecast comes on Tuesday, which will then follow with cooler and more seasonable conditions and temperatures.
