What Has Followed Some of the
Warmest Marches on Record
2012 ended as the second warmest March on record, just behind 1910. The unseasonable warm temperatures have kick started spring with many trees and flowers in full bloom, some a month early. You may be wondering if after the warmest Marches in the past, can we expect the warmth to continue in April, May. Below are some statistics using the 136 years of data from North Platte about what happened after previous warm Marches. Included below is the odds of a freeze, which is nearly 100 percent, for more statistics about the odds of a late spring freeze see here. Of the top 10 warmest Marches, 1878 had the least amount of days - 6 (1 was in May) with temperatures falling to or below freezing over the following 6 weeks. The warmest March on record, 1910, saw 10 days in April fall to or below freezing. 1910 also recorded 2 days in the month of May when freezing temperatures were recorded.
