How much it actually snows in Terrell County
Most winters bring Terrell County roughly 0.4 in. of snow - NOAA's normal at SHEFFIELD, TX US, 34.7 mi off. 34.7 mi is a real gap between Terrell County and its nearest reporting station, so local snowfall can diverge from this figure, especially near elevation changes. (fresh vs. packed vs. ice explains why.)
Read this before you rely on it
Terrell County's number above is ASCE 7-22's default case, not a custom calculation: ordinary residential occupancy, heated, sited on ground that's neither fully sheltered nor fully exposed. Any one of those changing - pitch, exposure, heating, occupancy - moves the real figure.
