8:00pm Update: Still no watches or warnings, but a storm has developed in Carrol County, moving east-northeast. Plenty of rain will be possible with these slow-moving storms, especially areas around Rockford later tonight.
7:33pm Update: No T-Storm Warning, but storms in Lee and DeKalb Counties capable of 50mph winds, 0.5" hail, and heavy downpours. Affected cities will include Paw Paw and Shabbona.
7:00pm Update: At the moment, storms are staying south of the Stateline. None of these storms are severe, but they will be capable of dropping several inches of rain due to their slow movement.
Because of this, the National Weather Service is growing a little more concerned about flash flooding for our southern counties and has expanded their Flash Flood Watch to include Whiteside, Ogle, Lee, and DeKalb counties through Wednesday morning.
Original Post: We are tracking the potential for severe storms across the Stateline tonight, especially later this evening.
Precision Doppler is showing some rain moving into Jo Daviess and Carrol Counties just before 6:00pm, but no thunderstorms at this time. The more active weather is still to our southwest.
Here's a look at watches and warnings as of 5:40pm. A Tornado Watch is in effect until 10:00pm for northern Missouri and southeastern Iowa. The closest severe weather is to our south... a Severe T-Storm Warning is in effect for Knox and Stark Counties in Illinois until 6:15pm.
When these storms move into the Stateline this evening, the main threats for severe weather will be strong winds and hail. While a tornado will be possible, it will only be a small chance.
We'll keep you updated as we go through the evening. Stay tuned! -BA
