“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 Union
Union gets 29 inches of rain and melted snow a year. May is the wettest month and January the driest. Rain or snow falls on about 86 days a year. Snow covers the ground about 50 days of the year.
About 168 frost-free days a year
In half of years the last 32° night comes by April 26 and the first one by October 11. That leaves about 168 frost-free days for gardens, shorter than 63% of U.S. towns.
Heating and cooling a home in Union
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Union, 88% of that work is heating and 12% 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.
Union and its neighbors
Union borders 4 towns with climate data. January nights across them vary by 0.4°. Ulysses has both the coldest January nights (14°) and the hottest July afternoons (86°). Union’s January low is 14° and its July high 86°.
Temperatures and rain come from NOAA’s 5 km grid, so each town gets its own value.

Temperatures and rainfall come from NOAA’s gridded climate normals for Union itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Shelby 3ne, NE (10 mi, snow) and David City, NE (6 mi, frost, heat and degree days). Normals are 30-year averages, not a forecast.
