Temperatures and rainfall come from NOAA’s gridded normals for Jefferson City itself (about a 3-mile square). Snow, frost dates and day counts: the NOAA station at Helena Rgnl Airport, MT (16 mi, snow) and Tizer Gardens, MT (1 mi, frost, heat and degree days). Sunrise and sunset are calculated from the town’s position. Normals are 30-year averages, not a forecast.
