Beginning December 8, 2009 and ending on May 29, 2010...the Lincoln National Weather Service Forecast Office (WFO Lincoln, IL) will begin modifying the Winter Weather (WSW) and Non-Precipitation (NPW) formats to produce experimental bulleted watch...warning and advisory products with a format similar to Severe Thunderstorm and Flash Flood Warnings.
These formats will be easier for users to read and quickly gather vital information during hazardous winter weather and non-precipitation events. During the test period...WFO Lincoln, IL may temporarily revert back to the current format to maintain mission critical warning services.
