An earlier Wind Chill advisory was cancelled was cancelled just after 10am, but it’s still cold. Official morning lows: 3 Lafayette, Ft. Wayne 4 Indianapolis 5 Muncie, South Bend 6 Terre Haute, Bloomington The last time the Indy recorded a high below 15 degrees was January 21, 2011. It’s likely to happen today, with a high of 13. The wind will decrease through the morning, diminishing to about 10 mph by lunchtime. Temps are back to the single digits tonight although the winds will stay lighter. We could see flurries tomorrow, and a dusting is possible north of Indy. Lake Effect snow continues around South Bend today, with a storm total of up to 3 inches in the city itself. Yesterday’s inch of snow finally put South Bend into double digits for the season. There’s been 10.8 of snow. Normally there’d be 36 inches by now. WIKI-POTEETIA: SNOW SCOREBOARD SO FAR 1.3″ Chicago/O’Hare 2.1″ Birmingham Jillian Boza on Facebook asks “Is a snow storm in our forecast Friday?” The answer is yes. It could start Thursday Night, and accumulate 2-4 inches by Friday afternoon. Here’s an interesting question from @tamremullins on Twitter: “How is the wind chill factor determined? How does it FEEL 2 degrees out?” The wind chill index be useful to explain how quickly frostbite might set in, and to express a consistent idea of what the temp “feels like” outside, because of the rate of heat loss from exposed skin caused by the effects of wind and cold. As the wind increases, the body is cooled at a faster rate causing the skin temperature to drop. Wind Chill does not impact inanimate objects like car radiators and exposed water pipes, because these objects cannot cool below the actual air temperature. A “new” wind chill index was deployed in 2001. The original index was based on empirical data developed in 1939 by two Antarctic explorers and was long been thought by the meteorological community to have been too simplistic and to have overstated the overall cooling effects of the wind. To address this, the National Weather Service made adjustments for the wind speed, which is generally measured at 33 feet. Those adjustments reflect the wind at a “face level” of five feet.
