Random Weather Facts

Wind Chill
Everyone has noticed that in winter it seems colder when the wind is blowing. Mothers recognize this and tell their children to wear more clothes. The question the children ask is how much more clothes. Mothers answer very precisely because Mothers know everything. For the rest of us, wind chill calculations are the basis for determining the effect of wind on body heat loss. The wind chill equivalent temperature equation is: Wind chill temperature = 35.74 + 0.6215T - 35.75V (**0.16) + 0.4275TV(**0.16) where T is the air temperature in Fahrenheit and V is the wind speed in MPH.

Weather History for March 14
 
1988
Squalls in the Great Lakes Region continued to produce heavy snow in northwest Wisconsin and Upper Michigan, and produced up to 14 inches of snow in northeast Ohio. Poplar WI reported 27 inches of snow in two days. (The National Weather Summary) (Storm Data)
1989
High winds in Colorado and Wyoming gusted above 120 mph at Horsetooth Heights CO. High winds in the Central Plains sharply reduced visibilities in blowing dust as far east as Kansas City MO. Winds gusting to 72 mph at Hill City KS reduced the visibility to a city block in blowing dust. Soil erosion in northwest Kansas damaged nearly five million acres of wheat.
