Wind chill advisory in effect until 11 a.m.
Johnson County is once again under a wind chill advisory issued by the National Weather Service. The advisory is in effect until 11 a.m. today. Southwest winds of 5-10 mph are expected to bring wind chill values of 15-25 degrees below zero. Temperatures this cold can be extremely dangerous, according to the NWS, and care should be taken to avoid hypothermia and frostbite.
There may be hope ahead though, as the weekend forecast from the NWS currently shows temperatures "improving rapidly" and reaching the mid-40s by Saturday afternoon.
