Notes
Today’s 0600 hour weather station conditions: outside air temp 29.1°F after passing astronomical twilight; wind calm; humidity 90%; pressure 30.15 inches Hg and climbing since midnight; skies: thin scattered cloud layers at 4K and 25K feet as measured by the LIDAR-based ceilometer; visibility unrestricted; soil temps at 3/5/8/16 inch levels 33/34/35/37°F; temperature-compensated soil moisture readings at 3/5 inch levels 25/21 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 0723:10 hours EST at station location; daylight duration 09:56:33 hours; Moon illumination last midnight 15.12%. Past 24 hours: lowest temp 23.4°F Saturday at 0711 hours; highest temp 60.7°F Saturday at 1539 hours; highest average five-second wind gust recorded SW@16.9 mph Saturday at 1400 hours; minimum wind chill 19° F; evapotranspiration (ETo) 0.04 inch; precip periods: none; total 24-hour precip: 0.00 inch. January cumulative totals: precip 0.84 inch; ETo 0.50 inch resulting in a January ground moisture surfeit of 0.34 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.
