Margusity's thunderstorm scale consists of five categories: TS1, TS2, TS3, TS4 and TS5, with TS5 being the most severe in terms of damage and impact. 
The scale ranks thunderstorms by a combination of their average rainfall rate, maximum wind gusts, hail size, peak tornado potential, lightning frequency and storm impact.

Cold fronts generally move from northwest to southeast. The air behind a cold front is noticeably colder and drier than the air ahead of it. When a cold front passes through, temperatures can drop more than 15 degrees within the first hour.]]> 2016-09-27 17:14:43 UTC https://padlet.com/kathy_witt/5th_thunderstorm/wish/126749551 derek_duclos https://padlet.com/kathy_witt/5th_thunderstorm/wish/126750230 A warm front is a density discontinuity located at the leading edge of a homogeneous warm air mass, and is typically located on the equator facing edge of an isotherm gradient. Warm fronts lie within broader troughs of low pressure than cold fronts, and move more slowly than the cold fronts which usually follow because cold air is denser and less easy to remove from the Earth's surface]]> 2016-09-27 17:16:34 UTC https://padlet.com/kathy_witt/5th_thunderstorm/wish/126750230 derek_duclos https://padlet.com/kathy_witt/5th_thunderstorm/wish/126751372 Hail is formed when very strong thunderstorm updrafts meet supercooled water droplets. Supercooled water droplets are liquid water drops that are surrounded by air that is below freezing which causes the rain to freeze and do to the moister in the storm more and more layers begins to freeze creating hail]]> 2016-09-27 17:19:23 UTC https://padlet.com/kathy_witt/5th_thunderstorm/wish/126751372 derek_duclos https://padlet.com/kathy_witt/5th_thunderstorm/wish/126754210 The sun heats the surface of the earth which warms the air above it. If this warm air is forced to ris in areas where cold and wet or dry together can cause rising motion as long as it weighs less and stays warmer than the air around it.

As the air rises, it transfers heat from the surface of the earth to the upper levels of the atmosphere ,The water vapor components start to cool and release the heat forming a cloud. The cloud eventually grows upward into areas where the temperature is below freezing. ]]> 2016-09-27 17:26:41 UTC https://padlet.com/kathy_witt/5th_thunderstorm/wish/126754210 kaitlyn_gholson https://padlet.com/kathy_witt/5th_thunderstorm/wish/126756379 https://youtu.be/zCQGR6Tl5ZM]]> 2016-09-27 17:30:54 UTC https://padlet.com/kathy_witt/5th_thunderstorm/wish/126756379
