The National Weather Service confirmed a tornado in Paw Paw was one of several that were registered across the region on Monday. There were also three tornadoes in Bureau County and a possible tornado in Ogle County.
An update from the National Weather Service shortly after 6 p.m. Tuesday confirmed the Monday tornado in Paw Paw.
Romeoville-headquartered National Weather Service meteorologist Rafal Ogorek said the first confirmed tornado on Monday was near Esmond in the far northwest of DeKalb County, and it’s possible that one also touched down in Ogle County. The Romeoville office confirmed 7 tornadoes in its monitoring area, including the Paw Paw one.
The NWS in the Quad Cities recorded three tornadoes in Bureau County on Monday.
The most significant one was about three miles west and southwest of Arlington. It had estimated peak winds of 105 mph, tracked for 3 miles and was 525 yards wide. It started in a cornfield and caused damage to four farms. Trees were snapped and four sheds were destroyed. Another 10 structures suffered damage. A farm outbuilding was destroyed near Arlington.
There was a tornado about four miles northwest of Princeton that was not classified that traveled a little over a mile and had a maximum width of 100 yards and caused damage to corn and soybeans along the path. The third was southeast of Van Orin that went only one-tenth of a mile.
Ogorek said heavy late summer storms Monday night made for weather patterns which are favorable for tornadic activity.
“The environment overall across northern Illinois was favorable for the development of tornadoes,” Ogorek said. “Oftentimes, tornadoes like to form on boundaries, and what we’re thinking is that there was probably some sort of boundary known as an outflow boundary that left behind storms earlier in the day and it’s possible that that might have been laid out right across DeKalb County.”
The NWS also issued a storm report on Tuesday’s storms that identified storm damage in Ogle County.
Two weather stations reported wind gusts of more than 56 mph in the vicinity of Rochelle. Tree limbs were reported down in Leaf River.
