Comparing January 34 to July

Posted: 16 Jan 2019 05:34 AM

The high temperature for Ames on Tuesday was just 34 degrees. That value is above average for the date, but sometimes such temperatures are hard to put into context. One way to provide such context is to compare temperature quantiles with another month, in this case July. The left hand chart is a q-q chart which plots equal percentiles for the month. Having the high of 34 in January compares with 88 degrees in July. So 88 degrees would be considered by most a warm July day, so yesterday was a warm January day too then!
