Despite a drier forecast, river flooding is possible this weekend

Remaining Ad Time Ad - 00:00

ROCKFORD (WREX) – A longer stretch of drier weather sets up starting Thursday, but that may not prevent river flooding before the end of the week. Minor river flooding is likely on sections of the Rock and Pecatonica rivers.

Any lingering rain showers should dry up early Thursday morning. The remainder of the day looks cloudy and dry. By that point, around 1″ of rain will have fallen around the Stateline. This amount of rain, plus rain amounts from earlier this week and last week, should be enough to cause some river flooding.

Winnebago County looks to be the only spot to see minor flooding. A stretch of the Pecatonica River by Shirland and Pecatonica may see minor flooding starting Saturday, and lasting until Monday night. A small stretch of the Rock River near Machesney Park will likely see the same thing. The rivers will be just above the minor flood stage. Impacts will be limited, and not nearly like what we saw a few months ago when major flooding hit.

The Rock River will be running high near Byron and Oregon, but flooding is not likely.

Any minor flooding will be short lived. Minor flooding will be over by Monday, with the rivers dropping from there. The forecast may still change, so stay alert.

A longer stretch of dry weather is helping limit the length, impacts, and scope of the flooding. Dry weather starts up Thursday afternoon, and lasts through Saturday. Sunday morning looks to have some light rain showers fall, but little accumulation is expected. Any new rain amounts from this possible round of rain won’t cause additional flooding.

Long term, much of next week will be dry, outside of Wednesday. The Climate Prediction Center’s outlook shows below average precipitation through the middle of the month. This bodes well for flooding to stay away long term.
