On July 7, 2015, NWS implemented changes to the icons depicted on all of its point-forecast pages. Changes include new icon images with increased clarity, 6-hour increments for rapidly changing weather and new color blocks to highlight forecast hazards.

A page depicting all of the new icon images can be accessed here: www.weather.gov/forecast-icons

Changes to the icons were based on analysis of 6,700 public comments collected in 2014. Also, many of these changes are based on the results of a research project led by the National Center for Atmospheric Research.

Users are encouraged to continue to provide comments regarding these changes via email at icons@noaa.gov. NWS will continue to analyze incoming feedback and refine the icons as necessary. Any substantial change to the icons will be facilitated through the NWS public comment/review process.

Above-normal temperatures continue across much of U.S.

Temperatures will once again be above-normal, in some cases by as much as 15-20 degrees, across much of the contiguous U.S. on Wednesday. Afternoon highs are forecast to reach into the mid to upper 90s across the Great Plains, as well as parts of the southern U.S. and mid-Atlantic. Take precautions if you plan to spend extended time outside.
