What's New?...

 

Changes to Cold / Windchill products for this season. The National Weather Service has simplified its suite of cold weather products to improve messaging of these hazards and provide better decision making services. The National Weather Service has also improved the watch, warning, and advisory criteria for the Extreme Cold suite of products to be climatologically based and informed by CDC, local forecasters, and partners.  These efforts are based on years of public and partner engagements as well as social science research informing the National Weather Service Hazard Simplification project.

 

Specifically, on October 1, 2024, the following changes were made:

Wind Chill Watches/Warnings were consolidated into Extreme Cold Watches/Warnings

Wind Chill Advisory was replaced with Cold Weather Advisory

These products will be issued as Non-Precipitation Weather Messages (NPWs) and not Winter Weather Messages (WSWs).

Our criteria for issuance has changed based on a nationwide climatology and impact analysis.

Previous NWS Windchill criteria for entire area was:

    • Windchill Advisory: -15F
    • Windchill Watch/Warning: -25F
