Barometer

The barometer was invented in 1643 by Italian Scientist Evanglista  Torricelli.  The barometer measures how much air pressure is in the atmosphere. A very detailed explanation is on Wickipedia that goes into detail on how he discovered this.

In short when we are having low air pressure - weather is getting an artic cold wave.  Well Kansas and much of the country is experiencing this right now.

Don't get me wrong I love winter and wouldn't want to live where the seasons don't change.  This is us this morning.
