Today’s 0600 hour weather station conditions: outside air temp 24.4°F after passing astronomical twilight; wind SSE@3.2 mph; humidity 89%; pressure 30.15 inches Hg and climbing since midnight; skies: broken clouds at 6K feet as recorded by the LIDAR-based ceilometer; visibility unrestricted; soil temps at 3/5/8/16 inch levels 38/40/41/44°F; temperature-compensated soil moisture readings at 3/5 inch levels 33/25 centibars in Buckhall silty clay loam with 3.7% fine gravel/particulates and 3¾ inch mowed dense fescue overcover where the FoxMill Weather Station ground sensors are located. Calculated sunrise 0722:09 hours EST at station location; daylight duration 09:27:49 hours; Moon illumination last midnight 3.85%. Past 24 hours: lowest temp 19.4°F Saturday at 0141 hours; highest temp 29.6°F Friday at 0952 hours; highest average five-second wind gust recorded SE@6.5 mph Friday at 0801 hours; minimum wind chill 13° F; evapotranspiration (ETo) 0.01 inch; precip periods: occasional light snow flurries Friday afternoon 1427 - 1520 hours, slightly over 0.1 inch averaged accumulation on three snowboards; total 24-hour precip: 0.013 inch (melted snow) recorded by the commercial calibration-certified piezoelectric rain gauge, corroborated by the CoCoRaHS manual gauge. December cumulative totals: precip 0.35 inch; ETo 0.40 inch resulting in a December ground moisture deficit of 0.05 inch 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. Station data reported by: observer2 (ampersat) foxmill.us at 0600 hours EST. FoxMill Weather Station, Saturday, 16 December 2017. |
