10/7/2017 8:00 AM 0.21 0.0 M 0.0 M need so much more rain than this. corn & soybean farmer in SW McHenry Co told me that they expect to be done picking corn by Halloween this year, usually they pick well into November, often finish by Thanksgiving. She said the pods of the soybeans have normal peas at the bottom of the pod that developed early in summer, and the top does not have peas or they are very small because of the drought. our grass is brown and leaves are turning brown and falling from trees.
10/8/2017 8:00 AM 0.26 0.0 M 0.0 M my station 3-day total only 0.49 inches. numerous radar runs on tv suggested our area might get more than one inch of rain.

Lawn is green again this am. By about 11pm last night had received about 0.5 inches, then heard loud thunder clap about 11:30pm followed by heavy rain - radar suggests rain continued through much of night. Light drizzle now.
