Roscoe gets 20 inches of rain and melted snow a year. June is the wettest month and January the driest. Rain or snow falls on about 73 days a year. Snow covers the ground about 30 days of the year.
About 163 frost-free days a year

Heating and cooling a home in Roscoe
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Roscoe, 86% of that work is heating and 14% is cooling, so the furnace matters far more than the air conditioner.
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.

Temperatures and rainfall come from NOAA’s gridded climate normals for Roscoe itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Ogallala, NE (7 mi) away. Normals are 30-year averages, not a forecast.
