7/1/2019 8:00 AM 0.17 M M M M As of this am, my station has received 39.09 inches of precipitation in this Water Year. The 30-yr annual average for Woodstock IL (the closest town) is 36.62 inches. With 3 months to go in the Water Year, my station is 2.47 inches over the annual average. My garden had been slow to grow given the cool and cloudy weather, and then the temps warmed and the rain began to fall. It is lush now. Frequently see standing water in fields that do not usually flood.

About 5:33 pm rain let up to moderate rate, and light rain had stopped about 5:50 pm. I used binoculars to watch rain gauge fill up quickly - could not believe what I was seeing in such a short period - wondered if it was capturing all of the rain that was falling because rain was blowing sideways.
