The canal has merged with & disappeared into the Illinois River. Because low-lying Canal Street was also closed, I couldn't get close enough to see, but Rt. 351 dips down low south of the bridge, so it's reasonable to assume 351 was under river water there.

7/10/2013 7:00 AM 0.22 M M M M 9:30am is just a guess at yesterday's rain start time. It ended at 11:20am with 0.22" in the gauge. Another guess is that we got another T of rain before dawn. There was no more water in the gauge, but the puddling on car roofs & hoods looked like way too much to be dew even though it's quite humid. Partly cloudy at obs: a cloud-chart sampler that I'm calling M8 altocumuli.

9/18/2013 7:00 AM 0.01 M M M M Overnight rain. Judging by the wet pavement at obs time, I would guess it might have fallen not long before dawn. L4 or L5 stratocumulus overcast at obs time. From my position under the clouds, I can't tell if they're spreading or not.
9/19/2013 7:00 AM 1.19 M M M M As stated in significant weather report issued yesterday, we got 0.99" of rain in just 49 minutes, from 2:24pm to 3:13pm. Thunder & lightning, too.

9/20/2013 7:00 AM 0.26 M M M M Late-night thunderstorm. It was so humid at obs time that for a second I thought rain was striking me, but it wasn't even mist; just dense humidity. L8 cumulus/stratocumulus overcast.

The main rain event started sometime around 8:30pm and continued on into the night. Light-to-moderate fog at obs time partially obscured what looked like an otherwise clear sky.
