This is a summary report of weather that occurred at my station in West Downtown Rochester and the Rochester Airport. 2012 will be a year to remember for many people as a year with a very early spring and hot and rather dry year. It ended out being the hottest year on record for parts of Southeastern Minnesota. I will have the happenings of 2012 into month by month statements. Information below will be from my station and yard. Below this statement I will have a statement with a summary of weather conditions from the official airport 7 miles South of my station as well. Information of records in both statements are based on records from the airport.
