10/8/2019 8:00 AM 0.20 M M M M We have been in a severe drought here, and still are. September and October we had temps higher than has ever been recorded many days. Four of the first six days of October were 100 or more. For some reason it has become difficult to get into your website, so I only report when we have rain or anything major. If no rain you probably won't hear from me.
