Lower 48 states report 12-warmest summer on record

Much of the West was warmer than average in August 2015.

4 states are record-warm for year to-date

Staff Report

FRISCO — While the Far West heat wave moderated a bit in August, four states in the region are record-warm for the year to date — California, Nevada, Oregon and Washington — according to the latest monthly climate update posted by NOAA’s National Climatic Data Center this week.

For the contiguous 48 states, the average temperature for the year to date was 1.6 degrees Fahrenheit above average, making it the warmest such period on record since 2012 and the ninth-warmest year to date on record. The summer months, June-August, were the 12th warmest on record, according to the NCDC report.

Along with higher-than-average summer temps, precipitation was also above average for the season, mostly due to a wet start to the summer. But August rainfall across the lower 48 states dropped off, leading to an expansion of drought in the South, where hot temperatures and lack of precipitation quickly stressed manmade and natural systems. Drought also worsened across the Northwest and Northeast.

For the entire summer, 11 states across the West and Southeast were much warmer than average. Oregon and Washington each had their warmest summer on record. Oregon’s summer temperature was 4.6 degrees Fahrenheit above average, besting the previous record set in 2003 by 0.6 degrees. Washington’s summer temperature was 5.3 degrees Fahrenheit above average, beating the previous record set in 1958 by 1.1 degrees.

From the Central Plains to the Midwest, cooler-than average temperatures prevailed, but no state was record cold.
