Q2 2017 (May - July) was warmest in 123 years of record. The warmest temperature anomalies were found in western states with California experiencing its second warmest May-July on record. Parts of the Deep South observed a cooler than normal Q2 2017, largely due to well above normal precipitation levels and frequent cloud cover. The Midwest and New England regions generally saw near average temperatures while the Mid-Atlantic coast states experienced above normal temperatures. May featured seasonally cool temperatures in the Heartland while warmer conditions were located in the Southeast and along the West Coast. June was cooler than average in the Deep South but a prolonged heat wave in the West led to the West Coast states observing a top 10 warmest June on record.
