April 2012 U.S. Temperature Departures from Normal
The attached map produced by our High Plains Regional Climate Center shows the April 2012 temperatures compared to the 1981-2010 standard 30-year climate normals. Areas in yellow, orange and red experienced above normal temperatures and areas in green experienced below normal temperatures.
It was a warmer than normal month for much of the area on the map with the largest departures from normal stretching from western Texas up along the High Plains to the Canadian border. This extreme warmth made the long term drought in the Texas Panhandle even worse. Ironically, the cooler than normal conditions in parts of the eastern Great Lakes resulted in a first ever recorded occurrence of April averaging cooler than the previous month of March.
The following map is a closer view of the High Plains region showing the temperature departures from normal for April 2012.
