You don't need a thermometer to know if winter weather has arrived, but you may need a dictionary to understand some of its terms.
Hoarfrost (yes, you read that correctly). It’s common on some of the coldest winter nights. You’ll see white crystals that form on vegetation or other objects such as spider webs or trees. Many refer to it as a Winter Wonderland.
What about wind chill? We’ve all heard of it, but what does it really mean? It’s the temperature your skin feels when wind is factored in.
It can also lead to frostbite, which isn’t a real bite, but can hurt just as bad. Frostbite happens when body tissue freezes, such as your fingers, toes, ear lobes or the tip of your nose. You can avoid this by dressing appropriately or staying inside on cold days.
Last but not least, know the difference between a winter storm watch vs. warning. A watch happens when there is the potential for hazardous winter weather in the next 48 hours. A warning means hazardous winter weather is occurring.
