For each station, you will see a temperature along with a pile of percentage columns. Here’s how it works: The percent column tells you the probability that you will experience that row’s temperature on or before that date.
So, for example, in the Spring 32° row, if you have “Apr 15” under the 50% column, that means that you have a 50% chance of seeing frost on or before April 15th.
Another example. Say in the Fall 24° row, under 90%, you have Dec 1, then that means that you have a 90% chance of seeing 24 degrees on or before December 1st.
Empty cells indicate you have a less than 10% chance of ever seeing that temperature.
