 * 		By carefully watching the pressure on a barometer, you can forecast local weather
 * 		using these simple guidelines:
 *
 * 			Decreasing barometric pressure indicates storms, rain and windy weather.
 *
 * 			Rising barometric pressure indicates fair, dry, and colder weather.
 *
 * 			Slow, regular and moderate falls in pressure suggest a low pressure
 *			area is passing some distance away. Marked changes in the weather are unlikely.
 *
 * 			Small rapid decreases in pressure indicate a nearby change in weather.
 *			They are usually followed by short lasting wind and showers.
 *
 * 			A quick drop in pressure over a short time indicates a storm is likely in 5
 * 			to 6 hours.
 *
 * 			Large, slow and sustained decreasing pressure forecasts a long period of
 *			poor weather. The weather will be more pronounced if the pressure started
 *			rising before it began to drop.
 *
 * 			A rapid rise in pressure, during fair weather and average, or above average
 *			pressure, indicates a low pressure cell is approaching. The pressure will
 *			soon decrease forecasting poorer weather.
 *
 * 			Quickly rising pressure, when the pressure is low, indicates a short period
 *			of fair weather is likely.
 *
 * 			A large, slow and sustained rise in pressure forecasts a long period of good
 *			weather is on its way.
