Instructions:

A wind chill warning means that a combination of very cold air and strong winds will create dangerously low wind chill values. Monitor the latest forecasts and warnings for updates on this situation. A winter storm watch means there is a potential for significant snow accumulations that would greatly impact travel. Stay tuned for later statements. This watch will be upgraded to a warning if winter storm conditions become more certain.
