The hottest year in Midstate history, by just two-tenths of a percent was 1921 when the average temperature was 62.5.Helping propel Warren and surrounding counties into the history books when it comes to heat were three days in late June and early July when the mercury tipped 106 degree to tie Warren County’s all-time record.
