May featured strong storms and even significant snow. It was also a warm month, ranking among the warmest third of the 131-year period of record. That warmth meant a rather warm spring for the country, with only the spring of 2012 ranking warmer.

The last month of meteorological spring ended up nearly two degrees above average. The contiguous United States had an average temperature in May of 61.7 degrees, 1.5 degrees above the 20th-century average, ranking as the 26th warmest May on record, according to the National Centers for Environmental Information’s (NCEI) U.S. climate report for the month.

There was a stark contrast among some of the biggest cities in the country. Houston had its 10th warmest May on record, finishing nearly two degrees above average for the month. Los Angeles was just over a degree above average during May, for its ninth warmest May.

Chicago came in at just over three degrees below average last month for its 16th coolest May on record, while New York City’s May was nearly a degree below average as it registered its 69th coolest May.

Severe and Unusual May Weather

The NCEI’s report also noted several “selected climate anomalies and events” that made their mark during May. There were over 200 preliminary tornado reports along with several reports of damaging winds and large hail as two large outbreaks of severe weather impacted the country during the middle of the month. The strongest tornado occurred in Marion, Illinois, on May 16, producing EF-4 damage with winds as strong as 190 mph.

Just prior to Memorial Day weekend, a rare nor’easter spun up along the East Coast. The storm brought late-spring snow to higher elevations in New Hampshire and also set record-cold temperatures at several locations in the Northeast. The powerful storm squeezed out more than seven inches of rain in Kingston, Massachusetts, and four inches of snow on Mount Washington in New Hampshire.

Warm May Rounds Out a Warm Spring

The country’s 26th warmest May was preceded by its 14th warmest April, and sixth warmest March, assuring a spring that would rank among the nation’s warmest. The average temperature for meteorological spring (March-May) this year was 54.1 degrees, 3.2 degrees above average, ranking it as the second warmest spring since records began 131 years ago. Year-to-date (January-May) ranks as the 18th warmest such period on record at nearly two degrees above average.
