This was then followed by a record drought across the region. On April 27, 2013 the running 365 day (1 year) total precipitation lost that heavy rainfall event. This dropped the running 365 day total from 8.45 inches to 7.23 inches. While the total of 8.45 inches was already near the lowest total on record, the total of 7.23 inches shattered the previous record of 7.87 inches set on June 9, 1932. The drought over the past year has dropped the running 365 day total to drop below 10 inches for the first time since 1940 at North Platte. Below is a graph representing the running 365 days total precipitation for North Platte, with a few dates highlighted. On the low end, the lowest total when a stretch fell below 10 inches.
