Over 300 locations in the U.S. had a daily warm temperature which was the warmest on record for April, according to data from the NOAA National Climatic Data Center (NCDC). Not only were many monthly records broken, but many of them were broken by a large margin – well over 1 degree Fahrenheit. Plotted in this image are the locations of the broken records for the highest monthly maximum temperature during April, along with shades of red indicating by how much the record was broken. Many of these records were concentrated in the Rocky Mountains and Southern Plains. Texas alone accounted for over 50 of these records. To note: for highly populated areas, there may be more than one automated surface observation station (ASOS) whose values are averaged to form a single grid point (pixel). The final statistics on the April 2012 U.S. climate analysis will be released by NCDC in the first week of May.
