Mesonet Station Summary

CAUTION: Mesonet data are only available since 1994, a period considered too short to give reliable climate statistics for temperature and precipitation. Cooperative observer sites are strongly recommended for these purposes. Other variables, such as humidity, soil temperatures, and winds, are not available from cooperative observer sites and Mesonet represents the best-available information.
