I don’t believe there will be anymore severe tonight. It’s been a while since we’ve had any warnings tonight. We’ll end our severe weather alert right here for the night. Thanks so much for stopping by. Feel free to leave any comments about the storms here or E-Mail us. Take care! -ERIC

6:54pm – Got off of the phone with Jo Daviess Co. sheriff. No reports of severe weather with the storms.
6:47pm – Quad Cities NWS: “Just checked with spc and they are concerned about redevelopment along primary cold front moving through nw ia. So we may be in a lull now but will have to watch for redevelopment over our area later this evening.”
6:40pm – I wanted to post a little analysis on the current radar. (Click to enlarge) Visible satellite and radar confirms a lull in the action southwest of the current activity. As I see it right now, our severe weather threat is diminishing for Whiteside and Carroll County. However, our atmosphere out ahead of the dryline is still very unstable. Threat not over entirely, but this is definitely a good trend to see! -ERIC
