Wind Chill: Does it really feel that cold?

Boy, was it great that President Obama's{ }inauguration and the inaugural parade was today and not tomorrow.{ } The coldest air in several years is coming in this week and after a very mild winter, WIND CHILL is the weather headline. Is this a real effect or something weather geeks have created?{ } Think about the last time you were in a crowded room.{ } Within a brief time the room probably got warm and stuffy.{ } We are alive, our body temperature is 98.6° and if there are 100s of us in a small space we heat things up.{ } But if someone turns on a fan, the moving air moves some of the heat away from us and our body "feels" cooler.{ } A diagram from{ }

{ }Now if you go ourtside with light clothing, when the temperature is 10°, but no wind,{ } your warm body radiates heat into the cold air and you feel cold . . .{ } get inside.{ } Now if you go outside (again light clothes-not naked, the neighbors would call the police) when the temperature is 25° and the wind is 20 mph, the wind chill is about 10° and heat leaves your body about the same rate as when the actual temperature is 10° with no wind. A bit simplified explanation but that's what wind chill is.{ } It sure is a real effect and the "wind chill temperature" is a calculation that tries to give you an idea of how cold it will feel (with light clothing) so you can take precautions and dress as though the wind chill was the actual temperature.{ } here is a chart.{ }

and here is what our wind chills around the area will approximately be Tuesday morning.{ }

Bundle up and make sure the youngsters are dressed safely heading to school tomorrow.{ } After this winter so far, tomorrow morning may feel like 50° below zero rather than "only 10°-15°.{ } We'll keep you posted.
