Extreme warmth continued in much of the Northeast during the spring, contributing to the region’s warmest March–May on record. The regional temperature average was more than 3.0°C above the LTA.
Eight northeastern states experienced their warmest spring on record, as did Michigan. Cool anomalies were present in several western states and in Florida.
Nationally, it was the 19th warmest spring on record.
Warmer-than-average conditions prevailed throughout much of the contiguous U.S. during the summer. Induced by a combination of a persistently
strong Bermuda High that extended abnormally westward and a strengthening La Niņa episode, the Southeast had its warmest summer on record.
Demonstrative of this irregularity, there were several other climate regions that were abnormally warm: Central (3rd warmest), Northeast (4th warmest), and the South (7th warmest). It was the warmest summer in 116-years of record keeping for every state in the Southeast climate region. A total of 12 states were record warm, while only two (Montana and Oregon) experienced an average temperature that was below the LTA. Overall, it was the fourth warmest summer on record for the contiguous U.S., with an average temperature of 1.0°C above the LTA.
Abnormal warmth continued into the fall season. While spatial temperature averages were variable across climate divisions, nearly every state averaged
a temperature that was above the LTA.
Rhode Island (6th warmest), Delaware (7th), and New Jersey (11th) each experienced the warmest anomalies, while
Florida, Georgia, Michigan, Montana, and Washington were the only states with average temperatures near the LTA.
