8/17/2020 5:36 AM 0.32 M M M M Nice but not quite wheat I'm looking for. Gusty winds. 30+ degree temperature drop from at least 103* to 73*. Rain was falling at a rate of approx 1/4"/hour then the "heavy" stuff came in.

8/30/2020 7:00 AM 0.26 M M M M Just what we've needed: a slow soaker. Not a monsoon deluge that runs off and is wasted.
