5/4/2012 7:00 AM 0.44 M M M M Severe thunderstorms blew through last night. The main core of precipitation passed to our Northwest. There is a significant rainfall difference between here and the northern part of Livingston County.

5/7/2012 7:00 AM 1.31 M M M M The total rainfall amounts from yesterday's severe weather. Even through this morning, there was widespread field flooding throughout town. Ditches were full. Some streets had either standing or flowing water on them. Part of IL Route 116, in between Pontiac and Saunemin was flooded, enough to where a detour was necessary. Flood problems should begin to resolve through the day, but it looks like it will persist for several more hours. The Vermillion is also rising. EDIT: Nickel to nearly Quarter size hail was also observed yesterday during a Severe Thunderstorm Warning. The largest hailstones fell at around 4:30 P.M CDT Sunday.

8/9/2012 7:00 AM 0.17 M M M M Occasional light showers throughout the day yesterday. The rainfall amounts were insignificant, but it was enough to give our soil moisture. The forecast calls for showers and thunderstorms likely. Maybe we will be lucky enough to get bigger rainfall totals after today.
8/17/2012 7:00 AM 0.52 M M M M A decent amount of rainfall fell during yesterday's thunderstorms. Finally! Should be great for the drought and for the river levels in our area.

8/27/2012 6:45 AM 2.00 M M M M The gauge read exactly 2 inches of rainfall this morning! This rain was definitely much needed. There wasn't any observed flooding from this event, but during the heavier bouts of rain, there was some runoff on area streets, but that did not persist for very long. Otherwise, this should put a dent in our drought.
