Air temperatures have dropped and winds have increased this morning. The combination of both have conspired to create dangerous wind chills. Many schools have cancelled classes today due to the wind chill. The NWS has issued a Wind Chill Warning for today until noon for much of Iowa. The featured chart presents the frequency of when during the day a wind chill warning is active for Story County (Ames). Rewording, when a wind chill warning is active, what is the frequency during the day that the warning was active. The afternoon hours are the least favored time, which makes sense as it will likely be the warmest portion of the day. Products like these are issued on a 3 hour increment of time, which is why there is a rapid cut off at noon.
