NWS N. Ind. cancels Winter Weather Advisory, issues Wind Chill Warning

Map showing locations of wind chill warning and advisory

The storm system that dropped a few inches of snow in northern Indiana, southern Lower Michigan and northwestern Ohio moved on quickly this morning, leading the northern Indiana office of the National Weather Service (NWS) to cancel early its Winter Weather Advisories for all but Berrien County, Michigan.

The office issued a new Wind Chill Warning, however, for most of the counties in its coverage area, including Allen County, Indiana (see map above) and a Wind Chill Advisory for several other counties. They both take effect at 10 p.m. EST tonight and run until noon Thursday.

In the area covered by the Wind Chill Warning, the NWS expects prolonged, dangerous wind chill temperatures of -15 to -30 degrees Fahrenheit.  In the advisory area, the NWS expects prolonged wind chill temperatures of -10 to -25 degrees F.

As you can see in the chart below, at a wind chill of -18, frostbite can occur after 15 or fewer minutes of exposure.
