Chart-busting 2012 temperatures in Lower 48 and Washington, D.C.

Temperatures so far this year are warmest on record locally and nationally, and it’s not even close. Year-to-date temperatures are on an entirely different level from past record-setting years.

Charts tell the story.


Chart shows year-to-date departures from normal for average temperatures from 1895 to present. The temperature departure in 2012 is more than a degree warmer than the next warmest year. View big. (NOAA)
The national year-to-date average temperature is 4.3 degrees above normal, 1.1 degree above the second warmest year on record: 1988.

In Washington, D.C., it’s a similar situation. The year-to-date average temperature is 4.6 degrees above average, which for statistics junkies is 3.2 standard deviations from the norm. The current year-to-date temperature is running almost 2 degrees above the next warmest year (since 1946): 1991

Examining state-wide temperatures, same deal. Both Virginia and Maryland have their warmest average temperatures year-to-date, 4.3 and 4.7 degrees above normal, respectively. Maryland’s average temperature is 1.3 degrees above the previous recordholders (frin 1998, 1991, and 2002) and Virginia’s average temperature is 0.8 degrees higher than the next hottest year: 1953.

34 out of 48 states and scores of cities are having their warmest years on record to date. These cities include (but are not even close to being limited to): Atlantic City, Baltimore, Chicago, Cincinatti, Des Moines, Detroit, Indianapolis, Little Rock, Milwaukee, Minneapolis-St. Paul, New Orleans, New York City, Oklahoma City, Philadelphia, Pittsburgh, Raleigh, Salt Lake City, and Tampa.
