Winter has returned!
When it is cold, how do I decide if it is cold enough to delay?
I rely on a wind chill chart put together by NOAA (National Oceanic and Atmospheric Association) and NWS (National Weather Service). This chart lets me know when the combination of air temperature and wind speed creates a wind chill that could cause frostbite. As you can see on the chart, I start to worry about wind chills around the -20 degree mark. It is always a tough decision that we take very seriously.
