Monday’s cold set the record for the Lowest March 4th High temperature. Shortly after midnight temperatures were at 16°, and this afternoon we didn’t climb higher than that mark, while most of the afternoon was spend in the teens. The previous lowest maximum for this day was 20° set back in 2002.
Days below 20° are actually pretty rare for March. The last time we had a high at 20° or below in March was back in 2015. Multiple occurrences of days 20° or below in March are also hard to come by, with it only happening 5 times in data that spans all the way back to 1897.
