How Early Is It To See Temperatures This Warm?

Spring is starting early and already we have seen record breaking temperatures, and more may be on the way this weekend. So how often do we get 70 or 80 degrees this early?

In Pierre, 70 and 75 degrees are pretty common in March. This year Pierre recorded 74 degrees on March 10^th. The earliest 70 degrees ever recorded was actually February 10^th of 1951. That day Pierre recorded 73 degrees. Pierre has also exceeded the 80 degree mark this year on March 13^th when 82 degrees was recorded. This was a daily high temperatures record for Pierre, but it was not the earliest 80 degrees ever recorded. That record is March 2^nd of 1974. Here are the top 5 earliest dates for Pierre to reach 70, 75 and 80 degrees respectively.
