“Wet days” have at least 0.01" of rain or melted snow. “Snow on ground” counts days with 1" or more. The 30-year range is the coldest and warmest that month’s average temperature got between 1991 and 2020.
Rain and snow in Alliance
Alliance gets 17 inches of rain and melted snow a year. May is the wettest month and December the driest. Rain or snow falls on about 84 days a year. Snow covers the ground about 65 days of the year.
About 144 frost-free days a year
In half of years the last 32° night comes by May 11 and the first one by October 3. That leaves about 144 frost-free days for gardens, shorter than 85% of U.S. towns.
Heating and cooling a home in Alliance
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Alliance, 91% of that work is heating and 9% 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 Alliance itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Hemingford, NE (18 mi, snow) and Alliance 1wnw, NE (1 mi, frost, heat and degree days). Normals are 30-year averages, not a forecast. Source: NOAA NCEI U.S. Climate Normals, 1991–2020 and 1901–2000.
