Combined ranking of states, based on:

   1) the most high temperature records broken (after accounting for the number of stations in each state, and the expected number of records) and
   2) the greatest disparity in the ratio between high and low record temperatures.

The total number of high-temperature records broken this year in every state through August 31. In this basic counting method, states with more stations have an advantage. Not surprisingly, Texas (with a nation-leading 232 stations reporting) tops the list.

The total number of high-temperature records broken in each state through August 31 divided by the number of stations in the state.

The total number of high-temperature records broken in each state through August 31 divided by the number of stations in the state, then adjusted for the length of the data record at each station. This accounts for the fact that it is tougher to break a record at a station with 100 years of data than at one with 40. This calculation yields the number of records broken compared to the number expected to be broken.

The ratio of record high-temperatures to record lows. In an unchanging climate the ratio of high-temperature records to low-temperature records is 1:1. So far this year, every state in the country is over the 1:1 ratio. Ohio leads the nation with a stunning 49-to-1 ratio of high to low-temperature records. Not a single state has seen more low-temperature records than highs (or even a 1:1 ratio).
