Numerous funnel clouds were seen late Friday afternoon into the earlier evening across Daviess County and extending into western areas of Grundy County. No damage was reported in either county, but two brief touchdowns were reported. The first was five miles southwest of Trenton around 6:14, and the other one mile south of Brimson about 15 minutes later. Dust was visible on the ground at both locations.
The National Weather Service was monitoring the thunderstorm activity, but did not issue tornado warnings. Significant weather advisories were issued by the National Weather Service as it received the funnel cloud reports and monitored the storms, that lacked signs of more dangerous “rapid rotation”.
Pamela Murray is a meteorologist with the National Weather Service in Pleasant Hill:
A severe thunderstorm warning was issued for northwestern Grundy and adjacent Mercer County. Storm spotters estimated winds to 60 to 65 miles per hour, hail between 1/4 to 1/2 inch in diameter, and heavy rain that reduced visibility to near zero about four miles west of Spickard. Storm spotters also reported some counter-clockwise rotation with the thunderstorm south of Modena, as the storm moved in a northeasterly direction. As a precaution, storm warning sirens were sounded throughout the town of Spickard.
