Huge Tornadoes Tear Across Kentucky, Alabama, Tennessee

There are communities in both Alabama & Indiana that are completely gone..

THE WEATHER CHANNEL LIVE STREAM

The long line of powerful tornadic supercells stretching from Arkansas all the way up into southern Ohio will continue to march in a ‘training’ fashion throughout this evening and unfortunately into the overnight hours. While much of southern Indiana has suffered significant to extreme damage, we’re seeing some of the strongest cells currently roaming across parts of northern Tennessee, central Kentucky.

Science Behind This Extreme Weather


TWC’s Dr Greg Forbes is currently discussing the setup with copious thunderstorms forming along a cold front associated with a storm system over the Midwest. The fuel from these storms is both the very sharp thermal contrast over the country with 10s and 20s over the Dakotas, 80s as far north as Tennessee and also the high ‘lapse rate’ which is measure of temperature contrast from surface to upper levels. Higher the lapse rate, the faster the upward motion can be. What’s making many of storms severe and tornadic is the ‘deep layered turning’ and ‘low level turning’ of the atmosphere which is responsible for ‘twisting or rotating’ these thunderstorms. A powerhouse jet stream racing overhead at 140 mph, low level jet racing at well over 60 mph from a different direction and the splitting of the upper jet also increases the violent rate of upward motion right where these storms are moving through.
