6/10/2018 7/24/2018 10:00 AM 45 0.00 M M This amount of rain was a total mystery to me. I have no recollection of any significant rain that I was aware of. This brings the seasonal total up to 41.00 inches. I just discovered it was a sprinkler that filled the gauge. OOPS! Sorry.
8/5/2018 9/30/2018 10:00 AM 57 0.45 M M Bringing the seasonal total up to 38.45 inches. I feel like this rain should be counted on next season's total, instead of this season. More rain due on 10/1/2018. Last actual report occurred on6/9/2018 but the site will not allow me to post over 60 day's span. What's up with that?
8/8/2018 8/09/2018 10:00 AM 2 0.00 M M I must apologize for the false report given on 7/10/2018. The reported 2.5 inches was from a garden sprinkler that was set too high. I just figured it out. the seasonal total is 38.50 inches; not 41.00 as previously reported. OOPS! Sorry!
