Active Weather for the West, Warming in the East

The potential for heavy snow at higher elevations in the western U.S. will continue for many spots through the weekend. In the meantime, the eastern half of the continental U.S. will transition to above normal temperatures ahead of a pair of cold fronts next week that will bring readings back to closer to normal as we approach Thanksgiving Day.

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 10th. The earliest 70 degrees ever recorded was actually February 10th of 1951. That day Pierre recorded 73 degrees. Pierre has also exceeded the 80 degree mark this year on March 13th 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 2nd of 1974. Here are the top 5 earliest dates for Pierre to reach 70, 75 and 80 degrees respectively.
