Calculated sunrise 0602:01 hours EDT at station location; daylight duration 14:28:38 hours; Moon illumination last midnight 14.85%.

July cumulative totals: precip 4.78 inches; ETo 2.88 inches resulting in a July ground moisture surfeit of 1.90 inch at FoxMill which correlates nicely (high R^2) with the observed soil moisture readings after accounting for the last precipitation type, weighted rate of fall, amount, duration, surface water runoff, ground temperatures, ETo and the previous 30 day rolling measured data.
