Check out the records at the National Climatic Data Center!
They have a web site that counts how many high and low temperature records have been set. More high temperature records have been set than cold record temperature records in the USA in the last several years.
For example, so far in 2016, 1290 daily record high temperatures have been broken in the USA. During that same time, 239 record cold temperatures have been broken. This weekend will add many for cold records, but go to the website to see the number of hot and cold records broken over the past 12 months!
