River levels continues to recede but upcoming rainfall by the end of the week could cause some local creeks, streams and rivers to rise again.
Most points along the Rock and Pecatonica river basin have fallen into either minor or moderate flood stage, making quite a bit of progress over the weekend. The rain that came down Sunday afternoon and evening remained mostly under a quarter of an inch, having little impact on river levels.
Skies will remain dry through Tuesday night with a slight chance for light rain Wednesday afternoon and evening. The rain chance will increase Thursday ahead of a cold front that will pass through the Stateline early afternoon. Ahead of the front, light rain and even a rumble of thunder or two, will be possible. The front will push south Thursday night taking the rain threat south with it.
The chance for rain begins to ramp back up during the day Friday and Friday evening as the front is pulled back north as a warm front. An abundance of moisture will lift into central and northern Illinois leading to the potential for heavy rainfall through Friday night. Rainfall totals could range anywhere from one, up to two, inches area wide — depending on where the frontal boundary stalls. Right now it looks like the higher rainfall totals may fall just to the south of the immediate area. However, with soil moisture still running extremely high any additional rainfall would most likely just run off into local creeks, streams and rivers.
Those who live along the rivers and in low-lying areas should pay close attention to the forecast this week. Rivers are expected to fall below flood stage later this week, but could be pushed back into at least minor flood stage for the upcoming weekend.
