Rain and snow in Osage
Osage gets 44 inches of rain and melted snow a year. May is the wettest month and January the driest. Rain or snow falls on about 91 days a year. Snow covers the ground about 8 days of the year.
About 197 frost-free days a year

Heating and cooling a home in Osage
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Osage, 71% of that work is heating and 29% is cooling.
Degree days measure how far each day’s average temperature falls below or rises above 65°, added up over a year. Source: NOAA station normals.
