As I’m typing this the link above shows 2.31 inches of rainfall at Farmington and 1.28 inches at Pilot Knob, but only 0.66 at Libertyville, and 0.21 at Roselle. And the current Roselle level is 3.47′.
Anyone care to make a rough prediction on what the level will be tomorrow morning?
Before you make any predictions, I found this cumulative precipitation map that shows the high (near 2″) precipitation to be only in a relatively narrow band, which won’t have as much effect on the river as 2″ across the whole watershed.
