Calculated sunrise 6:13:26 EDT at station location, daylight duration 13 hours 51 minutes. Past 24 hours: lowest temperature 50.6°F Sunday at 0542 hours; highest temperature 57.0°F Saturday at 1526 hours; highest sustained wind gust observed ESE@11.8 mph Saturday at 1033 hours; evapotranspiration (ET) 0.03 inch; precipitation periods: first sporadic raindrops observed reaching ground level Saturday at 1731 hours, measurable amounts by 1743 hours and continued intermittently at varying intensity levels through the 0600 hour CoCoRaHS gauge reading Sunday morning with peak rainfall period(s) at 0305, 0345, 0426, 0506, 0516 hours; maximum rainfall intensity 0.663 inch/hour Sunday at 0516 hours for 3 minutes; total 24-hour precipitation: 0.30 inch. April cumulative totals: precipitation 2.52 inches; ET 3.51 inches resulting in a monthly ground moisture deficit of 0.99 inch at FoxMill which correlates nicely (high R-squared) with the observed soil moisture readings after accounting for the last precipitation type, weighted rate of fall, amount, duration, ground temperatures, ET and the previous 30 day rolling statistical data.
